SOLAR SERDAR - USE YOUR ROOF !!!
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 solarserdar@gmail.com.
