Why we suggest solar thermal?

5 times powerful
compared to Photovoltaic

Photovoltaic
1m² = 0.1〜0.13 kW

Solar thermal
1m² = 0.7 kW

Under 1 kW/m² solar irradiation, when the temperature of Photo cell or Solar collector is equal to ambient air temperature, Efficiency of the Solar cell is about 10-13% while Efficiency of Solar collector is about 70%.
