| 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%. |
