The essentials about solar energy

When the sun shines, solar panels produce electricity. Logical, isn’t it? But even on less clear days, solar cells can produce electricity, although not at full capacity. This is comparable to our skin, which reacts to solar UV rays even when it is cloudy. Around 75 percent of the electricity generated by conventional solar systems installed in the lowlands, for example, is generated from May to September. In the mountains, a lot of winter electricity can be generated in the winter months with alpine solar systems. 

A typical solar panel (one square metre in size) made of commercially available silicon can generate an average of 180 watts on a clear, sunny day in Switzerland. That's enough to run a laptop computer. A solar power system consisting of several panels with a size of 20 square metres produces around 3,600 kilowatt hours (kWh) of electricity per year. In comparison, an average Swiss household consumes between 4,500 to 5,000 kWh of electricity per year.

As a general rule, the output of solar modules essentially depends on the amount of sunlight (global radiation/geographical location), orientation (the more precisely the photovoltaic system is positioned at the optimum inclination angle to the south, the higher the yield) and shade (from trees, chimneys, etc.) But, of course, the quality of the solar cells also has a significant influence on the overall performance.

Axpo and MOSOLF to build one of Europe’s largest solar car park canopy installations

Axpo and the MOSOLF Group, one of the leading system service providers to the automotive industry, are joining forces to build one of the largest solar car park canopy installations in Europe. The project, which was announced today, will be realised at MOSOLF’s site in Kippenheim, southern Germany. Covering an area of 109,000 square metres – roughly the size of 15 football pitches – the state-of-the-art photovoltaic system will feature over 54,000 solar modules with a total capacity of up to 24 megawatt peak (MWp).
