Energy from the sun.
The amount of energy our sun gives us every single day is equivalent to 2,850 times our worldwide energy needs. Depending on the region, around 1000 watts of sunshine per square meter reach the ground. Just what an inconceivable amount of energy this is becomes clear when you consider that the sun could meet one year’s worth of our global energy needs in just three hours. One thing is clear: we must take advantage of that.

SOLON SE is one of the largest solar module manufacturers in Europe and a leading supplier of photovoltaic systems for large-scale solar power plants. The SOLON Group has subsidiaries in Germany, Austria, Italy, Switzerland, and the U.S. The SOLON Group's core business is the manufacture of solar modules in various performance categories and of complete photovoltaic systems for the construction of solar power plants as well as the construction of turn-key solar power plants worldwide.SOLON SE was founded in 1997 and went public in 1998, making it the first listed solar energy company in Germany.

Group revenue for 2009 was € 354 million. SOLON employs about 900 people group-wide. More than half of revenue is generated outside Germany. SOLON anticipates a further significant growth for the coming years.

The company's success is driven by its passion for ecological change. This passion for a sustainable future is summarized in SOLON's central mission statement:

"We are passionate fighters for ecological change in the energy market. We revolutionize the usage of solar energy with our innovations. We are: The Pioneers of Power."More info at

How your power plant works.

1. Modules
SOLON photovoltaic modules consist of several interconnected solar cells made of the semiconductor silicon, which have a poly- or monocrystalline structure depending on the production technique used. A solar cell’s silicon is doped differently on the front and rear sides to create one positive and one negative charge carrier surplus, producing an electrical potential at the junction of the two differently doped layers. When sunlight strikes the solar cells, the silicon begins conducting and voltage is generated across the cells’ metal contacts, creating direct current.

2. Inverter
Direct current created in the solar cells cannot be fed directly into the public grid: an inverter converts direct current into 230-volt alternating current so that it can be used normally.

3. Export meter
You can use the produced energy in your own home or feed it inot the grid. Grid-connected plants require an export meter that measures the energy fed into the grid in kilowatt hours (kWh).

4. Public grid
The alternating current created and fed into the public grid can then be used by all consumers.

How to become an electricity producer.
A solar plant from SOLON pays for itself in three different ways: it converts free solar radiation into valuable electricity, protects our environment and gives you a high-yield capital investment for decades of high returns. All with low operating costs and without added risk. You could call that a real investment for the future.More info at

Project development.
Our specialist partners will put you in touch with a SOLON installer in your area. He or she will perform a general assessment to determine the suitability of your home by using your house’s building plans or through an on-site appointment. If the result is positive, a yield simulation and subsequent profitability analysis for your roof will be performed. Many SOLON installers will also be able to help you hold any necessary discussions with the bank and public authorities.

Planning and construction.
As no roof is identical to another, your pv system will be planned individually. During installation, the installer will be your expert contact person when it comes to construction management, scheduling and installation.

Opertion and service.
As soon as all work has been completed, your solar power plant can be connected to the public power grid. That means it is time to sit back and enjoy the sun!

In many countries you will also enjoy these exclusive benefits with your SOLON solar insurance*:
Loss-of-production coverage when exchanging the inverter
Reimbursement of all costs incurred in connection with roof repairs resulting from damage to the PV system (e.g. caused by snow pressure)
Cost coverage (removal and reinstallation costs, transport and storage costs) as well as reimbursement for loss of output in the event of removal of an undamaged system

* Applies to Germany, Spain, Italy, Portugal, Denmark, Poland, the Czech Republic, Austria, France, Luxemburg, Belgium, Finland, Sweden and the Netherlands.More info at

SOLAR SERDAR - Solar technology FAQs:

What is photovoltaics?
Photovoltaics is the direct conversion of solar energy into electric current using solar cells.

How do photovoltaics work?
When light strikes a solar cell, it creates an electric voltage between the surface facing the light and the surface turned away from the light. When the electric circuit is closed, electric current flows. (Source: DGS)
What does a solar power system consist of?
The base unit of a PV system is the solar module. Several modules are connected to a solar generator. Because the generator creates direct current, it requires an inverter to convert the direct current into alternating current for standard electrical applications. The electricity is then fed into the public power grid via a meter.
What is a module made of?
The main components of the modules are the solar cells. Several of these cells are combined into one module. The module is then laminated in a plastic layer and framed between a glass cover plate and a rear panel.
What steps are involved in the value creation chain for module creation?
Silicon raw material is derived from silicon-rich rock (e.g. sand). The silicon is melted to form blocks known as ingots. The ingots are then cut into paper-thin discs called wafers. The wafers are then used to make solar cells that form the main constituent of module production.
What kinds of PV systems are there?
In general, there are two different kinds of systems:
1. Structure
The most common type of mounting is the rooftop installation. This method makes particularly efficient use of space. Further mounting options include rooftop integration and building integrated systems.

2. Freestanding
Freestanding plants are systems that are mounted on the ground. The modules can be fixed or installed so that they track the sun.
How is a photovoltaic system different from a solar thermal system?
Instead of generating electricity from sunlight, a solar thermal system generates heat in the form of hot water or heat energy.

Use roof areas.
Many rooftop areas in industry and commerce are still unused.

What many companies do not know: they are losing promising additional income because rooftop photovoltaic systems can be used to generate extra profit.

Rooftop systems from SOLON.
A solar power system from SOLON is a profitable choice and a simple and safe investment. Our "all around carefree package" means that you do not have to worry about planning, construction or initial operation. SOLON and its partners will take care of all that.

Even after installation, everything has been arranged: a 10-year product warranty, a 25-year performance guarantee and integrated solar insurance are proof of that.
Highest performance during each phase of your project.
Solar systems on industrial and commercial buildings are a profitable business. In conjunction with our partners, we develop solutions that are custom-made for your requirements.

SOLON quality, which is renowned in this industrial sector, and our global references provide all the requirements for financing your project. SOLON is a listed company and therefore provides two essential benefits: transparency and financial strength.

Step by step to a sustainable investment.

SOLON can be your experienced partner. From planning to a turnkey solar plant. See for yourself: we have compiled a brief description of the most important project phases to give you an impression of a typical SOLON project:
Project development.
You have chosen a rooftop photovoltaic system and thus a sustainable investment. Congratulations - also to the environment!

Solar energy is the cleanest, most abundant, renewable energy source available. And the U.S. has some of the richest solar resources shining across the nation. Today's technology allows us to capture this power in several ways giving the public and commercial entities flexible ways to employ both the heat and light of the sun.

The greatest challenge the U.S. solar market faces is scaling up production and distribution of solar energy technology to drive the price down to be on par with traditional fossil fuel sources.

Solar energy can be produced on a distributed basis, called distributed generation, with equipment located on rooftops or on ground-mounted fixtures close to where the energy is used. Large-scale concentrating solar power systems can also produce energy at a central power plant.

There are four ways we harness solar energy: photovoltaics (converting light to electricity), heating and cooling systems (solar thermal), concentrating solar power (utility scale), and lighting. Active solar energy systems employ devices that convert the sun's heat or light to another form of energy we use. Passive solar refers to special siting, design or building materials that take advantage of the sun's position and availability to provide direct heating or lighting. Passive solar also considers the need for shading devices to protect buildings from excessive heat from the sun.
Solar is an Emerging Economic Engine
A robust solar industry in the U.S. is an economic engine that will help relieve a struggling American economy. With aggressive and effective national policy, solar power will create tens of thousands of jobs across the country and will spur billions of dollars in economic growth and tax revenue. Consider the growth of solar in 2007:

New solar installations nationwide increased by more than 40 percent from 2006 to 2007.
Expansions of solar energy companies resulted in 6,000 new jobs, 265 megawatts of energy and more than $2 billion of investment in the U.S. economy by Wall Street firms such as JP Morgan, Chase and Goldman Sachs.
The first utility-scale solar power plant in the U.S. in 18 years went online.

The National Renewable Energy Laboratory (NREL) estimates that an additional thirty gigawatts of solar energy will be deployed as a result of the recent eight year extension of the solar investme. This is enough energy to power more than five million homes! NREL also estimates that the solar market would continue to drive increased deployment even after the tax credits expire.

An expanding solar market creates thousands of new jobs - jobs like electricians, construction workers, plumbers, line workers, roofers, engineers and high-paying manufacturing positions - for a struggling economy.

Solar Leads the Way in Stabilizing America's Energy Security
Energy security is increasingly finding its way into the national consciousness. Whether in terms of national security or our ability to respond to domestic challenges such as natural disasters, energy is one of the most critical issues facing the U.S. Solar provides crucial energy supplies vital to the function of homes, businesses and the entire economy.

The hurricanes in the fall of 2005 were a stark reminder of the vulnerability of our domestic supplies of oil and natural gas to severe weather and environmental factors. Not only does solar energy provide reliable access to energy where it is used, but it can supplement energy needs in blackouts and disaster recovery for electricity, water pumping and hot water.

With the cost of oil rising to more than $130 per barrel, a gallon of gasoline to more than $4 at the pump and skyrocketing electric bills, Americans are feeling the squeeze. Complicating matters, most of America's energy supply arrives from politically volatile regions of the world. Rapidly growing economies, such as China and India, are staking larger and larger claims to dwindling global energy resources. According to the Energy Information Agency, two-thirds of the petroleum and 20 percent of the natural gas consumed in the U.S. is imported from other countries, and U.S. production of both is dropping while consumption continues to rise.

A fully-developed U.S. solar market will decrease our overdependence on foreign sources of oil and natural gas and meet long term demands for domestically produced clean energy. The U.S. must make a long term investment in a diverse, clean, and renewable energy portfolio - with solar in the lead - if it is to have a secure energy future. More info at

Harnessing the Power of the Sun to Confront Global Climate Change
As global climate change impacts the way the U.S. addresses environmental policy, conducts business and harnesses energy, the solar energy industry is leading the way with a renewable energy source that creates economic growth and reduces carbon emissions. Solar is an pollution-free source of electricity and hot water that can be immediately deployed to reduce the nation's growing carbon footprint.

As the federal government considers climate change legislation, Congress should create carbon output-based market rules that encourage carbon-free technologies and allow energy sources such as solar to be rewarded for producing
Myths and Facts
MYTH #1: Solar devices require more energy to manufacture than they produce in their lifetime.

This study by the National Renewable Energy Laboratory (NREL) conclusively demonstrates that energy payback for photovoltaic (PV) power is, in the worst case, less than 4 years. Given that PV module lifetimes are generally in excess of 20 years, a PV system will produce far more energy than it consumes over its lifetime.

Technological progress in the four years since the issuance of this report has tended to bring down the energy consumption of PV manufacturing yet further, as silicon growth processes in particular become more efficient.

Energy output and input ratios for concentrating solar power (CSP) and solar thermal devices are even more favorable, given their simple manufacture. As best we can determine, this myth has its origins in the early history of PV power, when devices were essentially custom-fabricated for military, space and research markets.

MYTH #2: Solar manufacturing results in more pollution than is saved by solar usage.

As shown in the NREL study above, a PV system meeting half of the electrical needs of a typical household would eliminate approximately half a ton of sulfur dioxide pollution from the air, and about 600 lbs. of nitrogen oxides. In contrast, the pollutants produced in the manufacturing process are minimal and largely recycled.

CSP plant equipment and solar thermal devices are essentially specialized formations of glass, steel, aluminum and plastics; their manufacture is comparable to that involved in making household windows, water heaters or mirrors.

PV devices are essentially "electric glass." Their typical silicon substrate is a close relative of window glass. The processes used to render it electrically reactive are the same as are used in the microchip manufacturing industry, acknowledged by states and municipalities as a clean manufacturing process.

MYTH #3: Solar is too expensive for widespread usage.

Solar PV technologies have declined in price every year since they were introduced onto the market, driven by improved research and development, and most of all by steady increases in sales volume. (In 1954, approximately one watt of PV generating devices was manufactured. In 2004, approximately one billion watts will be manufactured worldwide.)

Every solar panel purchased makes the next one cheaper, in stark contrast to nonrenewable sources, which become scarcer and more expensive with every ton that is burned.

PV has recently exploded into a number of industrial markets, where it is quite simply the lowest -cost source of power available. These include highway warning signs, rural irrigation applications and remote electrical and communications devices. Similarly, for any application more than about half a mile away from the electrical grid, a solar system will likely prove less expensive than will power line construction.

The most rapidly-growing segment of the solar industry is for "grid connected" systems - rooftop solar panels on homes or businesses that remain connected to the conventional electrical grid. In some cases, as where electricity is more expensive during the middle of the day, or when solar is used to support power-critical applications (e.g. banking, microchip manufacturing), the economics are very compelling without further incentives. In other places, comparatively modest state or federal incentives (listed comprehensively at can make solar a great investment for home or business owners that betters with every year. Utilities and large consumers are becoming more conscious of the value of solar and other generation sources with the publication of works like "Small is Profitable" - available at

MYTH #4: Solar won't work where I live.

Solar thermal and PV devices are dependent on light, not heat - and this light does not need to be direct. Put another way, if you can find your way around outside, a solar panel could be working. The map below shows solar resources throughout the U.S. While the Southwest enjoys particularly good resources, the entire U.S. has adequate solar resources.

More important than place-to-place variations in solar intensity is the price of daytime electricity where you live and the existence of state incentives for clean energy. A solar contractor in your area can give you a good idea of whether solar is right for you.

enXco, an EDF Energies Nouvelles company, and Portland General Electric (PGE) have entered into two power purchase agreements for solar photovoltaic installations to be located in the Willamette Valley near Salem, Ore. The two installations will combine for a total of 2.84 MW of generating capacity, providing power for approximately 2,300 homes at peak production.

enXco will develop, build and own the thin-film solar projects. PGE will purchase the power generated under a 25-year power purchase agreement. The projects are expected to commence construction in early 2011 and reach commercial operation in July 2011. enXco Service Corp. will operate and maintain the projects.

"These projects represent the largest ground-mounted solar PV installations in the Pacific Northwest, as well as the first solar development for enXco in the region," notes Troy Gagliano, project developer at enXco.

Both sites are located in the southeastern portion of Yamhill County. The Bellevue Solar project site will produce 1.69 MW, and the Yamhill Solar Project site will produce 1.15 MW. The projects will connect to the existing PGE utility system.

The highest demand for PV inverters this year will come from both the smallest and the largest three-phase inverters, according a recently released report on the market from IMS Research. Shipments of inverters rated below 35 kW and above 500 kW are growing nearly 50% faster than the rest of the market.

The PV inverter market has achieved remarkable growth in the past few years, overcoming the collapse of the Spanish market to produce record shipments in 2009 - a feat set to be broken again in 2010 with close to 17 GW of shipments, IMS Research says. This growth has attracted many new entrants to the market, especially suppliers already active in similar markets.

However, although these suppliers have transferred their expertise in high power and produced large central inverters, it is the smaller three-phase products that are predicted to capture a greater share in the short term.

IMS Research’s recently published report has revealed that shipments of small three-phase inverters rated around 10 kW to 20kW are forecast to grow by around 170% this year. Inverters rated at over 500 kW are projected to grow at a similar rate but will capture a smaller share of the market.

In the longer-term, however, much faster growth is predicted for these larger inverters, with utility-scale installations emerging rapidly – although, due to their inherently lower price per watt, these inverters will still only account for 10% of revenues in 2014, the report says.

"Recently, demand for PV inverters in commercial installations appears to be splitting into two clear categories: very small three-phase products or very large central inverters," says Tom Haddon, PV research analyst at IMS. "While mid-sized central inverters offer a lower initial investment cost, shipments of inverters in the 10 kW to 20 kW range have increased massively in 2010, with a range of new models being released by major suppliers such as SMA, Kaco, SolarMax and Power-One.

"These products offer greater system design flexibility, easier installation and higher energy yields, and also better grid integration - a crucial factor, given the medium-voltage directive and reactive power legislation in Germany," Haddon adds.

Although it is forecast that these units will lose some market share to larger central inverters in the longer term as the emerging markets of the U.S., India and China drive demand for megawatt-sized substations, in the medium term, smaller three-phase models are forecast to be one of the prime revenue generators, as their adaptable nature can be applied to installations ranging from small commercial to multi-megawatt utility-scale installations.

Fotowatio Renewable Ventures (FRV) has begun a major expansion of the Colorado State University (CSU) solar plant at the Foothills Campus. The 3.3 MW addition, which will be located adjacent to the 2 MW facility that opened in December 2009 on Chrisman Field, is expected to be completed within four months, according to FRV.

With the expansion, the entire project will generate a total of 8.5 million kWh of electricity annually.

FRV will own the solar facility and will be responsible for operating and maintaining it over the 20-year contract term. FRV and CSU have entered into a power purchase agreement that enables CSU to purchase the electricity produced by the plant at a fixed rate for 20 years, without any up-front cost to the university. The university also has the option to purchase the solar plant at the end of the 20-year contract for the fair market value. At that time, the university could claim the full value of the renewable energy credits (RECs) generated by the plant.

The project is part of the Xcel Energy Solar Rewards program. Xcel will purchase the RECs generated by the system in support of Colorado’s renewable portfolio standard, which requires utilities to generate 30% of their power from renewable energy sources by 2020.

Global Energy Services will install the project as an FRV contractor. Advanced Energy, based in Ft. Collins, Colo., is supplying the inverters for the project.

ART TEC Solar has developed the DTC-D solar differential temperature controller, which is designed specifically for PV-powered collector circulation pumps used in solar heating systems.

This digital controller includes an internal battery backup that allows the controller to continue to display current temperatures and record maximum/minimum temperatures in the absence of solar power for several days, the company says. The controller's backlight makes it easy to read in dark utility rooms.

Features include max temperature shutoff, with optional over-temperature audible alarm, freeze alarm with optional freeze pumping for systems that operate from batteries, and resettable max/min display of recent temperature extremes. Front-panel controls allow easy changes to settings and manual override of the pump to on, off and auto modes, the company adds.

The new differential temperature controller will be available in November.

Why Invest in Renewables?
If you're not at the power table, you're on the menu. Welcome to the Power business.

At this moment in history, a unique opportunity, barely recognized as yet, has presented itself to all of us who work for a living in America. We have the chance to take control of our own future as it relates to energy and power, food, and our local economies.

First, let’s look at Energy.

Distributed Renewable Energy is a concept that, until very recently, applied only to a few off-grid hippies, usually in the mountains somewhere. But oh how times have rapidly changed, and now these formerly mysterious technologies can become a very powerful force in shaping the future of our city.

We have a small window of opportunity here.

Our big government and big energy and power companies are planning your energy future right now. Their plan includes solar, wind, and a lot of coal. Their plan includes transmission fees, distribution fees, line loss fees, maintenance fees, infrastructure development fees, special assessments, big salaries, municipal taxes, state taxes, federal taxes, and more subsidies than ever before.

Thus far, our country has run almost exclusively on big, centralized power. We have grown up believing that this is normal and natural. But this is not the case at all.

Right now, before they can tax us into a second job, we can act. When we invest our own money in solar and wind, we can secure a future with far less need for coal and no need at all for all those taxes, fees and subsidies that can be raised every year without notice. We can use geothermal systems for our heating, air conditioning and hot water. We can use the grid (conventional power and electricity) for back up only, and sell back power, at a profit, whenever we have excess. We can also invest in carbon reduction projects, carbon financial instruments, carbon futures, and renewable energy credits.

Right now, big Energy and Power is investing in all these things, including geothermal, solar, and wind. And in the next five years, you are going to buy someone solar panels. If that someone is not you, the solar power you buy from them will be taxed and tarriffed. It will make you madder than anything that’s happened thus far. But the window will be closed, the opportunities gone.

Oh, you’ll pay for solar panels, anyway. But they won’t be yours. Still doubting...

Here are the Facts:

Natural Gas Prices are now at $1.25 per therm, commodity only, and are expected to nearly double in the next twelve months.
Electric Prices are higher than ever since recent deregulation and are forecasted to increase dramatically (25-40%) in the upcoming months.
Also, the greatest tax incentive that nobody talks about -is that there is no tax on your renewable energy system.

Well, you ask -how much money are we really talking about?

First, I will breakdown the cost of conventional electricity for one of our commercial clients:

For the month of May, our client, a large plastics manufacturer, was billed $23,778.31, of which $9095.93 was fees, taxes, and additional assessments. That means that Transmission Charges, Transmission and Distribution Loss Charges, Customer Charges, Franchise Costs, State Taxes, Municipal Taxes, Instrument Funding Charges, Environmental Cost Recovery Adjustments, Standard Metering Charges, Distribution Facilities Charges, and Nonstandard Facilities Charges, account for an additional 61%, on top of our clients actual electricity usage cost.
Next, we will examine natural gas costs for a typical Chicago 4 bedroom, 2 bath home.

For the month of April Natural Gas (Commodity) Costs totaled $177.03, on top of which our residential client paid an additional $65.49 in taxes, fees and assessments, including Monthly Customer Charges, Environmental Cost Recovery Charges, County, Government, Agency Comparative Adjustment fees, Franchise Customer Adjustment fees, Municipal Utility Taxes, Utility Fund Taxes, and State Revenue Taxes, which added an additional 39% to the Natural Gas usage cost.
In both of these examples, we see that added to the already steadily increasing, volatile cost of conventional Electricity and Power, fees, taxes and assessments add, on average, an additional 30-60% to your power and electric costs. Wouldn't you like to save that money, year after year?More info at

Other reasons to go renewable:

Take advantage of Federal tax credits and incentives, available for businesses and homeowners, accelerated depreciation for businesses, and state rebates, for RE energy systems.
Consider that heating your hot water is the second biggest natural gas expense, and you use it every day, all day--all year long. Shouldn't you save money on such a necessary expense?
Don't forget that Renewable Systems, like solar, wind and geo, add value to your property and are exempt from property taxes.
Own your energy at a fixed cost and free yourself from the rising, volatile cost of conventional power and energy, while Renewable systems for businesses and multi unit properties offer positive publicity opportunities while increasing assets and lowering liabilities.
Solar Energy will extend the life of your hot water heater and furnace by reducing their workload, and a geo system will completely eliminate your need for a furnace. In addition, Renewable Systems are long-lasting, cost efficient, quiet, reliable, and require very little if any maintenance.

SOLAR SERDAR - Extended-Range Electric Vehicle

SOLAR serdar Extended-Range Electric Vehicle (EREV)
Current car batteries usually take several hours to fully charge, so Battery Electric Vehicle (BEV) usage is limited to commuting and other short trips by the battery range.

To extend the range, some BEV manufacturers add a highly efficient Internal Combustion Engine (ICE) powering a generator when the batteries are low. Such vehicles are called Extended-Range Electric Vehicles (EREVs), as well as Range-extended Electric Vehicles (ReEVs) or Series Plug-in Hybrid Electric Vehicles (SPHEVs). Several models are to be commercialised as of 2011 (including GM's Chevy Volt and Opel Ampera). More info at

For short distances, which represent about 80% of cars mileage, EREVs can operate in full electric mode and are therefore as clean and energy-efficient as BEVs (unlike parallel hybrids).

For longer distances, which represent only about 20% of cars mileage, EREVs operate in generator mode, in which they consume noticeably less fuel than conventional Internal Combustion Vehicles (ICVs) because:

The engine of an EREV is significantly smaller than of a conventional ICV, because EREV engine must only cover average power needs (peak power being delivered by the batteries), while ICV engines also must cover peak power surges (accelerations).

The engine of an EREV operates at a constant, highly efficient rotation speed, while the engine of an ICV often operates at low or high rotation speeds at which its efficiency is low.
We do promote EREVs as long as their battery power is sufficient for most commuting and other short trips, for which they will run on batteries (because it is much cheaper).
We recommend that the minimum battery power should allow an effective electric range of 50 to 100 km (75 to 150 km nominal).More info at .

In a more distant future, two cleaner technologies should replace EREVs:

Ultrafast charging BEVs: Ultrafast charging stations, charging BEV batteries in less than 15 min, could spread on road networks. This would allow BEVs to charge nearly as conveniently as fuel cars and make them competitive against EREVs for long trips.

Fuel Cell Vehicles (FCVs): they are also very clean and can be refuelled quite fast. The could thererefore compete against EREVs in the future.
While FCVs are likely to become the winning technology in some transport applications, it is not yet clear which technology will win the passenger car market. It will largely depend on the cost of the vehicle and of the refuelling infrastructure (fast charging stations versus hydrogen refuelling stations).
AVEM is the Association for the Future of the Mediterranean Electric Vehicle. Founded in 1997, it aims at promoting actions for the development and use of electric vehicles.

AVEM has a network of more than 100 partners. Created in 2006, its website is a leading source of reliable information on electric vehicles in French, with a readership of more than 700.000 visitors in 2009.
ThePlugincompany, market leader in Belgium and Luxembourg, is a leading provider of sustainable and easy to use “plugin” solutions for recharging and driving electric vehicles.

Solar energy is not only easy to use – it has the most power from all renewable energy forms. Just a small fraction of the solar radiation that hits the earth would be sufficient to cover world energy consumption. And that – at least with regard to primary energy costs – is free of charge: sunlight costs you nothing.

However, not only the quantity is impressive. Solar energy is particularly attractive due to its cleanliness. There are practically no emissions and no dangerous radiation. So it is well-suited to tackle current climatic problems.

In order to use solar energy, no new and complex technologies are needed that would probably make no contribution to generating energy in the near future, despite intense and costly research. Already today, largely matured technologies are available which allow efficient use of solar energy.

Last but not least: fossil fuels are becoming increasingly scarce and ever more expensive. At the same time, energy demand is continuously increasing, especially in the aspiring Asian nations. We can predict that this will have significant political, economical, and ecological consequences. Solar energy can be an efficient instrument to counteract this alarming development.
Over 95 % of today’s solar cells consist of the semiconductor material silicon. Semiconductors are materials whose electrical conductivity increases with the influx of light or heat.

For the production of solar cells, the silicon is doped. For this purpose, other chemical elements are added, either creating an electron surplus (n-conductive layer) or an electron deficit (p-conductive layer). If two differently doped semiconductor areas convene, a so-called space charge zone is created at the boundary layer (p-n transition).

In order to achieve the desired effect, the initial material is normally lightly p-doped and a thin surface layer heavily n-doped. This creates the space charge zone required for separating charge carriers.

The front contact is a metallic mesh, enabling the sunlight to penetrate the silicon between the contacts. Moreover, solar cells are coated with an anti-reflection layer, serving to protect the cell and to reduce energy loss resulting from reflection. This layer gives the solar cells their typical bluish black appearance.
As a home owner, you can take the opportunity to use your roof as a small power station – without any effort as all the work is done by the solar cells. Modules made by SOLAR SERDAR can be installed by several different means in various ways, making them extremely versatile.More info at

SOLAR SERDAR recommends SolarWorld

SolarWorld is the largest PV manufacturer in the U.S. and is currently building its network of installers across the country. Our modules are completely Made in the USA (98.6%) and lead the competition on energy production based on independent studies.
How a PV cell makes electricity

Under the sun, a photovoltaic cell acts as a photosensitive diode that instantaneously converts light – but not heat – into electricity.

Cell Layers

A top, phosphorus-diffused silicon layer carries free electrons – unanchored particles with negative charges. A thicker, borondoped bottom layer contains holes, or absences of electrons, that also can move reely. In effect, precise manufacturing has instilled an electronic imbalance between the two layers.

Sun Activation

Photons bombard and penetrate the cell.
They activate electrons, knocking them loose in both silicon layers.
Some electrons in the bottom layer sling-shot to the top of the cell.
These electrons flow into metal contacts as electricity, moving into a circuit throughout a 60-cell module.
Electrons flow back into the cell via a solid contact layer at the bottom, creating a closed loop or circuit.
SolarWorld manufacturers solar panels entirely in the USA from raw silicon to completed solar panels. This process involves four main steps: crystal growing, wafering, solar cell production and solar panel assembly. Learn about each of the four steps below.

Crystal growing
Solar cell production
Solar panel assembly
SolarWorld heats and melts polysilicon rock until it forms a whitehot liquid, then re-fuses the molten silicon into a single giant crystal in which all atoms are perfectly aligned in a desired structure and orientation.


The magic starts with about 250 pounds of polysilicon rocks carefully stacked in a quartz crucible. The only other ingredient is a silicon disk impregnated with a tiny amount of boron. The addition of the oron dopant ensures that the resulting crystal will bear a positive potential electrical orientation. The crucible is encased within thick walls of insulating graphite and locked inside a cylindrical furnace.More info at


As the crystal-growing furnace heats up to temperatures ranging around 2,500 degrees Fahrenheit, its silicon contents melt into a shimmering slurry. Once computerized monitors register the right temperature and atmospheric conditions, the alchemy begins. A silicon seed crystal, hung from a narrow cable attached to a rotary device atop the furnace, is slowly lowered into the melt.


The crucible starts to turn, and the seed crystal begins to rotate in the opposite direction. The silicon melt freezes onto the seed crystal, matching the seed’s crystalline structure. The crystal grows, the cable and seed slowly ascend, and the crystal elongates at a controlled width. As the growth depletes the silicon slurry, the crucible also rises.


Flash forward about 2.5 days since the crucible was charged with polysilicon: After hours of cooling to about 300 degrees Fahrenheit, the furnace hood and shaft lift away from the crucible encasement, slowly swing to one side and reveal a completed cylindrical crystal, ready to move to the second step and next production room.
A silicon crystal must change shape several times before it winds up as the precisely calibrated wafers that form the foundations of photovoltaic cells.


First, a saw cuts off the crystal’s so-called top and tail, so that a crystal of uniform width remains. Typically, wafering saws draw thin wire bearing a liquid abrasive across the crystal’s surface. (Below, a machine mounted with a giant donutlike steel blade does the cutting.) Wire saws also cut the crystal into ingots measuring 2 feet or less. Steel holders are mounted on the ends of these ingots for the next step.


Mounted ingots are placed standing on end in a rack bearing 16 at a time inside another wireslicing machine. There, wire running in a lattice configuration descends on the ingots to shear off four rounded segments, leaving flat sides. The result: The ingots now have a square crosssection, except for still-rounded corners.


The next wire saw is more intricate yet. A wire winding hundreds of times between two cylindrical drums forms a web of parallel, tightly spaced segments. As the wire unspools through the machine, ingots mounted sideways on glass and metal holders are pressed two at a time through the wire web, slicing them into the thickness of slim business cards. Each millimeter of crystal yields about 21/2 wafers. Detached from their holders, the wafers are loaded into carriers, or boats, for transport to the next step.
Converting wafers into cells

At this point, a wafer is no more capable of producing electricity than a sliver of river rock. The wafer is the main building block of a PV cell, but so far its only notable characteristics are its crystal structure and positive potential orientation. All of that changes in the third, multistep, cell-production phase of PV manufacturing.More info at


In the only phase requiring a designated clean room, a series of intricate chemical and heat treatments converts the blank, grey wafers into productive, blue cells. A so-called texture etch, for instance, removes a tiny layer of silicon, relying on the underlying crystal structure to reveal an irregular pattern of pyramids. The surface of pyramids – so small they’re invisible to the naked eye – absorbs more light.


Next, wafers are moved in cartridges into long, cylindrical, ovenlike chambers in which phosphorus is diffused into a thin layer of the wafer surface. The molecular-level impregnation occurs as the wafer surface is exposed to phosphorus gas at a high heat, a step that gives the surface a negative potential electrical orientation. The combination of that layer and the boron-doped layer below creates a positive-negative, or P/N, junction – a critical partition in the functioning of a PV cell.

Coloring and Printing

The burgeoning, still-grey cells move in trays into heavy vacuum chambers where blue-purple silicon nitride is deposited onto their tops. The coating with silicon nitride – yet another member of the silicon family of materials – is designed to reduce reflection even further in the energy-dense blue end of the light spectrum. It leaves the cells with their final, dark color. Now, the cells can optimally gather photons and produce electricity. They lack, however, any mechanism to collect and forward the power. So, in a series of silkscreen- like steps, metals are printed on both sides of the cell, adding pin-stripe "fingers" and bus-bar circuitry. A functioning cell is born – only sunshine needed.
Stringing cells into solar panels

Each phase of production depends on processes with flavors all their own. Careful control of heating and cooling dominates crystal growing. Wafering employs abrasion and cutting. Cell production concentrates on chemistry. Any factory process would be incomplete without a final assembly step, and in PV such a step is known as moduling.


At SolarWorld, module manufacturing is a highly automated process, relying on robust steel robotics to undertake the increasingly heavy lifting of assembling lightweight PV cells into modules weighing around 45 pounds apiece. Each robotic tool works within a safety fence that, by design, excludes people. First, cells are soldered together into strings of 10, using an over-under-overunder pattern of metal connectors to link the cells. Six strings are laid out to form a rectangular matrix of 60 cells. Each matrix is laminated onto glass.


To become a module, however, each laminate requires not only a frame to provide protection against weather and other impacts but also a junction box to enable connections among modules or with an inverter-bound conduit. Robots affix those, too.

Inspection and Shipping

Careful cleaning and inspection provide final touches before each module can be palletized for delivery to homes and businesses.

Is Solar Right For Me?

Solar is right for most every home, depending on your motivation. Are you interested in solar purely for economic benefit? Are you concerned for our environment or the social responsibility of your business? Are you concerned for our environment or the future health of your family? Are you bothered by the fossil fuel situation and wish to declare your energy independence? All of these are great reasons to go solar! Below are a few limiting factors to getting the most out of your solar electric system:

Do you have a south-facing area of roof or land that can accommodate your solar system?
A south facing roof is going to provide the optimum potential for your system. Depending on your building orientation, other directions can also provide sufficient production; please consult us for these details.
Do you have unobstructed space available for your system?
Each kilowatt (kW) of solar contracted will cover approximately 100-150 sq. ft. of area. This can be a roof, parking structure, ground area, etc. If you do not have ample, unshaded, structurally sound area for solar, then your property may not be well-suited for solar.
Do you have any daytime shading issues on your south-facing space?
Trees, neighbors with larger buildings, vents, or other factor that cause shading throughout the day will cause significant decreases to your power production, therefore not making a suitable building for solar.
Will you need to repair or replace your roof in the next 5 years?
If so, then you may want to wait to add your solar system during that time, or consider re-roofing now to add your system.
