About Solyndra: The Rooftop Solar Leader

Headquartered in Fremont, California, Solyndra designs and manufactures solar photovoltaic (PV) systems, comprised of panels and mounts, for the commercial rooftop market. Solyndra’s technology is a proven and scalable solar solution that offers strong ROI and economics for the rooftop owner. The company has installed its systems on more than 1000 rooftops in more than 20 countries. In 2010 Solyndra was named “One of the 50 Most Innovative Companies in the World” by MIT’s Technology Review Magazine. Using innovative cylindrical modules and thin film CIGS technology, Solyndra systems are designed to provide the lowest levelized cost of electricity and the highest kilowatt hour production per rooftop for typical installations. The unique Solyndra form factor is designed specifically for the commercial rooftop, offering the fastest and easiest installation, a non-penetrating mounting system, and superior wind, snow and soiling performance. In addition Solyndra offers energy and conservation advantages when installed in conjunction with a white or “cool” roof. 

Founded in 2005, today the company manufactures its products entirely in the United States in a state-of-the-art 300,000 square foot front-end manufacturing factory and a 500,000 square foot back-end facility. The manufacturing facility has helped Solyndra drive costs down dramatically allowing the company to offer highly competitive “all in” installed cost on the rooftop. In 2011 Solyndra will double it’s production capacity, ramping toward 300MW. The company employs approximately 1050 employees around the world and has offices in the United States, Switzerland, Germany, Italy, and France. Revenues were approximately $140 million in 2010.



Solyndra Cylindrical Module

Benefits of a Cylinder

Solyndra designs and manufactures proprietary cylindrical modules incorporating copper indium gallium diselenide (CIGS) thin-film technology. Our panels employ cylindrical modules which capture sunlight across a 360-degree photovoltaic surface capable of converting direct, diffuse and reflected sunlight into electricity. In the industry sometimes panels are referred to as modules; at Solyndra, each panel is made up of individual modules.

Reliable Manufacturing

A Solyndra module starts in our front-end facility as a glass tube and passes through a complex, highly-automated manufacturing process and rigorous quality control before emerging as an encapsulated package ready to efficiently convert energy from the sun. There are approximately 23 steps to build and protect the 195 thin-film solar cells created in the manufacture of each module, encompassing cleaning, deposition, scribing, binning, insertion, filling, testing, panel framing and flash testing.

Each module in a 200 Series panel has 195 individual solar cells.The inner cylinder is protected by a liquid optical coupling agent (OCA) which serves as a moisture barrier and increases the active solar cell surface of the internal tube.

Each module is designed to produce electricity for more than 25 years in the harsh environment of the rooftop.The hermetic seal on our glass tubes ensure the CIGS material inside remains protected from contamination. Each tube is helium leak tested.

Solyndra’s factory has produced over 16 million modules and each day produces approximately 1000 panels or 40,000 modules ramping to more than 3000 panels a day in 2013.

Broader Shoulders: More Power During the Day

The tubular design of a Solyndra module is “self-tracking”. Collecting light around a 360 degree surface allows it to capture more light early and late in the day. with broader shoulders and less peak during the day. This consistent power generation during the day allows the use of a smaller inverter, saving costs and benefits the overall energy yield of a system over time.

Advantages with Snow and Soiling

Because of our unique design, light snow falls through the Solyndra panels and the panels actually benefit from the increased albedo (reflected light) from a fresh snowfall. Solyndra systems experience less system loss due to snow.

The cylindrical design attracts less dirt and airborne particles, and moisture or rain that lands or forms on the modules works to clean the cylinders. Research shows that energy loss due to soiling on Solyndra systems is approximately half of that for conventional flat panels.

Solyndra Agricultural Solar Products

The rapidly expanding use of agricultural shelter structures in warm climates offers an exciting opportunity for greenhouse and shade structure rooftops to generate clean energy from the sun while optimizing plant growth. Greenhouses topped with Solyndra panels allow more light through than a traditional flat panel application and benefit from the light weight of the panels.

Benefits of Solyndra Greenhouse Applications

  • Uniform overhead shading and lighting at crop surface
  • Rapid installation, light construction
  • Configurable, seasonal shading with addition of reflective cloth
  • Quality construction, 20+ year life

Benefits of Agricultural Solar

  • Dual land use
  • Additional revenue stream for farmers
  • Distributed power
  • Tax incentives
  • Reduced electricity bills

A Unique Application for Agricultural Greenhouses

Solyndra offers a solar application for agricultural greenhouse and shade structures that takes advantage of the ability of light to pass through Solyndra’s proven solar panel design. Installation of Solyndra’s unique solar panels on agricultural structures allows for dual use of land, and reliably supports existing agricultural practices, while generating considerable electricity. The Solyndra solution enhances plant growth by controlling shading and provides growers with an additional income stream and power for their operations. Research by renowned agricultural establishments, such as CeRSAA in Italy and the Department of Plant Sciences, University of California Davis, USA, has confirmed the superior nature of the panel design and their ability to support crop growth underneath while generating electricity.

Greenhouse manufacturers can easily integrate Solyndra panels onto the roof of a greenhouse or shade structure. Complete coverage with Solyndra panels maximizes energy output per acre and generates a uniform shading comparable to the light transferred through conventional shade structures or the process known as whitewashing. The cylindrical design of the modules enables them to capture sunlight and generate electricity from direct, diffuse and reflected light. Growers with Solyndra-enhanced greenhouses may add an optional shade cloth to protect plants that require more shade during certain months of the year. Using a white cloth also allows some of the light to reflect back onto the tubes thereby increasing the energy output of the system. A venting system at the gables can also be used, since air circulation is important for plant health.

“This product, which supports plant growth and provides both shade and a distributed power source is the best idea I have seen for what could ultimately be the ideal application of solar power – dual purpose agricultural-land use,” says Dr. Giovanni Minuto of CERSAA, a research center in Albenga, Italy, who has been evaluating the Solyndra system over the past year with a variety of plant types and under various weather conditions.

Test sites at prestigious agricultural research establishments like CeRSAA and the Department of Plant Sciences, University of California, Davis, have demonstrated that plants, such as nursery crops and ornamental flowers grow well in the partial shading provided by Solyndra systems.

While the use of Solyndra panels on agricultural greenhouses is relatively new, Solyndra solar panel technology has been proven in installations on more than 1000 commercial and industrial rooftops around the world. Panels come with mounting solutions and cable management systems, which are then integrated into greenhouse structures by leading manufacturers in Italy. Currently, multiple megawatts of agricultural installations are underway. Solyndra also offers a solution for the rooftops of large, flat agricultural warehouses and distribution centers.

Solyndra is working with leading greenhouse manufacturers, EPCs (engineering, procurement, construction) and banks in Italy. Interested growers and agricultural cooperatives should contact Solyndra to be put in touch with an integrator in their area.


Cool, Powerful Roofs
CoolRoofs_Frito

Cool and Powerful Commercial Roofs

Building owners around the world are discovering the benefits of combining the power generation capabilities of a Solyndra solar power system with the energy conservation benefits of a white “cool roof”. Solyndra’s unique cylindrical solar modules are designed to capture additional refracted light from white roofs to raise the overall amount of electricity generated by the system. Albedo is the portion of light that is reflected from the roof and the more light reflected, the cooler the roof which is why building owners around the world are turning to white roofing membranes, or spray on white roof coatings. And while all solar systems perform better on white roofs due to lower ambient temperatures, Solyndra offers a number of additional advantages. Along with our non-penetrating mounting design and simple installation, one of the most important considerations in the United States are federal tax incentives that apply to both solar systems and the roof. More Info

Cool Roofs Reduce Building Energy Needs

If you are considering a new roof, you should consider a white roof and a solar system on that roof at the same time. A cool roof reduces building cooling requirements by lowering the temperature of the roof and the building underneath. This means cooling equipment savings and in many cases the ability to run less air conditioning or purchase smaller air conditioning units.

You may even increase the life of your roof. By lowering the roof temperature, roofing products may last longer due to less thermal stress over time. Our non-penetrating design means less opportunity for leaks from your new roof.

While it makes great economic sense, a cool roof also makes an important statement about your commitment to reducing your building’s impact on the environment. One clear environment benefit comes as cool roofs reduce the “heat island” effect in cities, lowering average outside air temperatures. Lower the outside air temperature and you need even less cooling. In fact, U.S. Energy Secretary, Steven Chu said that “whitening the world’s roofs and roads would have the same effect on global warming as removing all the world’s cars for 11 years.”

Solyndra Solutions Providers have a wide range of specialized models and tools to help you understand the many factors involved in deciding if a cool roof and solar system are right for you and your business and we can help you find a roofing expert to discuss your reflective roofing needs.

For more information, the U.S. Department of Energy offers a great cool roof guide.

Solyndra Fab 2 Hitting Production Targets

SOLAR TODAY tours the Solyndra factory.

By Seth Masia


Solyndra, the spanking-new, fully automated photovoltaic (PV) factory in Fremont, Calif., has hit some important production targets this year. According to a press release, the company shipped 70,000 modules in the first quarter of 2011, doubled U.S. sales in the first half and exported more than 50 percent of its production. It’s now shipping 2,000 modules a day, averaging 205 watts per module, in a factory running 24 hours a day, seven days a week, with a goal of expanding out to 200 megawatts (MW) this year and 300 MW soon. The existing buildings may eventually handle 450 MW.

Solyndra has also become a political football. A 2009 federal loan guarantee amounting to $535 million has been targeted for investigation by Rep. Fred Upton, R-Mich., chairman of the House Energy and Commerce Committee.

The White House Office of Management and Budget (OMB) this week delivered 1,400 pages of emails concerning its final review of the loan guarantee. OMB promised more documents soon.

On Tuesday, Upton accused the OMB of stalling, and threatened a subpoena. Upton and his staff are investigating whether Solyndra deserved that loan guarantee, and a subsequent $75 million Department of Energy (DOE) loan made after the company canceled a June 2010 initial public stock offering that was supposed to raise $300 million. The company has since raised significant new venture-capital investment.

The original loan guarantee was offered, in part, because the DOE estimated the new factory would employ 3,000 workers in construction and provide 1,000 permanent production jobs. According to David Miller, director of corporate communication at the Fremont plant, the company already employs 1,100. That includes 300 workers in this building on each shift, including front office and design staff. Since the factory has reached only about a third of its production potential, it would appear that it’s on track to be a significant employer, as promised. The loan guarantee backed about 74 percent of the financing to build the new plant.

An important criterion used by the DOE in this loan guarantee program was the technology’s readiness to achieve mass production quickly. Solyndra, then a start-up, applied for the guarantee in 2006 under the Bush administration. After three years of review, the deal was offered in March 2009 — the first such loan guarantee offered under the American Recovery and Reinvestment Act. Construction of the 1 million-square-foot LEED-certified building began in September 2009 and Fab 2 shipped its first product within a year. Solyndra then shut down the original fab 1, with its 45-MW annual capacity.

Roof Solyndra is a copper indium gallium (di)selenide (CIGS) thin-film product, with a nominal conversion efficiency of about 13 to 14 percent. The 7,000 panels on the factory roof produce 1.23 MW to power the office space, about 25 percent of the building’s current load. That works out to 175 watts per panel, but Miller points out that the array includes a lot of early production and quality-challenged modules. “If we were to do the same system for a customer it would be about 5,000 panels,” he said. That would be 246 watts per panel, close to the company’s goal of 250 watts in the near future. The best panels going out right now test out at 220 watts.

Each tube is a multi-layer concentric assembly. The CIGS tube is of tempered glass, progressively coated with copper, indium and gallium selenide. It’s scribed in a helical pattern, and then scribed again along its length to divide the CIGS layers into 200 cells. Inside that tube is a long, thin Mylar gas bag to compensate for thermal expansion of the helium atmosphere inside the finished tube. The CIGS tube in turn is contained in an acrylic plastic tube, and the entire assembly is protected by another external tempered glass tube. A clear oily fluid sits between the acrylic and outer tubes to help refract light around the cell cylinder, and the ends are hermetically capped in much the way a fluorescent tube is sealed. One end becomes an anode, the other a cathode. So the wiring harness built into one rubber-coated structural side rail delivers a positive charge, the other negative.

If you were to roll the CIGS area out flat, it would measure 467 square centimeters. That multiplies to about 1.87 square meters for a panel. Because only half the tube faces the sun, Solyndra’s literature claims one square meter of equivalent PV surface. But to get the claimed power output at 14 percent efficiency, it’s clear that photons are also harvested on the underside of the panel, from backscatter off a high-albedo roof.

The assembly line is fully automated. One of the first workers I encountered on a tour July 11 was a squat, cubic delivery robot, autonomously carrying a pallet of material from the loading dock. This rubber-tired hod carrier broadcast the theme from “Raiders of the Lost Ark” in place of its original warning beeper, which human employees had found annoying.

Once loaded into the front end of the production line, the tubes are never again touched by human hands. All inspection, cleaning, coating, scribing, assembly, sealing and testing processes are handled with linear equipment. Stationary robots handle transfers between conveyor lines, just as happens in a highly-automated flat panel factory. Human supervisors handle workstations monitoring several processes at once, with video close-ups of critical steps. A big difference: no screen printing or soldering stations.

The lines are set up to run 24/7 for three weeks at a time, and then pause for a rapid maintenance break. Miller likens the pause to a pit stop. When everything runs as designed, a stack of 40 tubes moves through the line from receiving dock to shipping dock in 24 hours.

Solyndra pitches a unique product, promising rapid, nearly tool-free installation and light footprint. Each 60-pound Solyndra “panel” is a 1-meter-by-2-meter collection of 40 tubes, designed to stand about a foot off a flat white roof. Because the wind goes through the open grid, Solyndra claims stability to 130 mph (210 kph) when the modules stand on their own snap-in-place feet. Add ballast or tethers, and wind safety goes to 180 mph (290 kph). Snow falls straight through the grid, and an array adds 2.8 pounds per square foot (13.7 kg per square meter) to roof loading. Panels are easily unsnapped and moved for roof maintenance or to accommodate new rooftop equipment. Because the sun always faces a convex surface, Miller says, the daily power curve is broader and flatter than that of a non-tracking flat panel.

Solyndra now claims more than 1,000 installations completed in more than 20 countries, totaling more than 100 MW. Regardless of what the House Committee does, the company expects black ink this year.
