FAQ - Fragen zu Anlagen

As far as solar radiation is concerned, Central Europe is obviously not in the same league as locations close to the Equator where up to 2,500 kWh/m² can be attained.
However, with an average of 1,000 kWh of solar energy per m² per annum, the sun provides more than enough energy even at our latitudes.

Theoretically, the annual amount of solar radiation on a square surface of about 4,225km² (edge length: ~65 km) would be enough to cover the total electricity requirements of Germany (measured according to the gross amount of electricity generated in 2006) with the help of photovoltaics.

Thus the challenge lies simply at the storage technology level and not at the level of radiation of the “giant power plant” sun whose capability is beyond question – even in Germany.
With a Gecko plant of about 30 m² on the roof, a family of 4 with an average annual consumption of electricity of 3,500 kWh would not have to worry about their energy requirements.
