Performance Increase by Cooling ����
Earth temperature: 6 to 12 �C
Cooled PV as Solarthermal Collector ����
High thermal yield: (>600 kWh/m² a)
Seasonal Geothermal Storage
Summer: temperature lower than air temp.� water condensation
Winter: de-icing possible
- less shading by snow,
-lesser weight on the roof
lesser energy costlesser energy cost
