How to Collect 100kWh of Solar Power per Day
Calculation Size 1:
A. Start amount 100kwh
B. The 100kwh/500wh/person = 200 persons on the 50km round trip per day.
C. Taking into account the SHE internal losses, (100kwh/4.5kwh/m²) * 2 = 44.44m² of solar concentrators for the first start up day.
D. Amount to be collected 100kwh * 2 = 200kWh
E. At 70% efficiency: 200kWh * 0.7 = 140kWh to the
heat storage.
