4 autonomous Solar-Power-Plants with the sides lengths of 4km Each Mirror-Field has a Size of 16km², together 64km² The Power-Plants are designed with a Thermal-Storage of 15h, so that they can supply 24h electricity - so they are capable of base load Operating-Time up to 8000h/pa Cleaning and Inspection of the Mirror systems is fully automatic at Night The depreciation period can be estimated at > 50 years due to the longevity of the Sota-Domus Mirror Technology The output of all 4 Solar-Power-Stations is 3.84GW - as much as 4 medium Atomic-Power-Plants The amount of electricity generated per year is 21.120 GWh Berlin, for Example, Capital of Germany with 3.8 Mio. Inhabitants and a large Industry, consumes in the Year 13.433 GWh - with only 62% of the Power-Plant-Capacity we could supply All of Berlin with Electricity!
