The sun provides us with a virtually never-ending supply of energy. The amount of solar energy which reaches the earth each hour is enough to satisfy mankind’s entire annual energy requirement. Experts estimate that this free source of energy will be available for the next four billion years.

What makes more sense than to avail of this free source of energy? Especially when one considers the finite supply of fossil fuels, constantly increasing environmental pollution and the discussion on climate change, now is the time to turn to this clean energy and make more use of it.

Photovoltaics are a way of using solar energy which can already be implemented now. Photovoltaics is an invented word, made up of a combination of the word Photon, the Greek word for light, and the name of the physicist Alessandro Volta. Photovoltaics is an umbrella term which defines the physical process of generating electrical energy from sunlight.

Many million square metres of photovoltaic elements installed on buildings and in open spaces which generate electricity in a variety of ways prove that this principle not only works in the world’s deserts, but also in Central Europe.

The systems don’t have to be as large as a football field. Today, small-scale systems offer suitable conditions to allow energy-conscious home-owners to produce their own electricity.In contrast to fossil fuels, the raw materials required to produce the solar cells which are usually used in photo-voltaic modules are available in large quantities. The silicon required is the second most common chemical ele-ment in the earth’s crust. It is to be found in common-or-garden quartz sand, among other sources.

The yield of a photovoltaic system depends to a great extent on all system components suiting one another optimally, and being coordinated for one other. Only perfect coordination of selected products guarantees maximum yields.

After exhaustive tests and a stringent selection procedure our engineers have assembled systems using the very best components produced by leading German suppliers. This allows us to guarantee and document optimal compatibility of all components.
