The energy consumption of ourself in 2010 was 3300KWh. The yearly earning by the sun is more than this. So for planing a PV system in the area of Stuttgart we can roughly say: for a consumtion of 3600KWh/a you need a PV system of 3600 KWp. With our PV system we saved in 3,5 years 7,8t CO2 output. Our yearly family CO2 production could be reduced from 55 to 28t CO2/a.
We are in future not 100% delivered to price increasings.
And we do something for a livable future on earth.
