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
