With front to rear cooling surface ratio 1/20, 95% of all heat dissipates at rear side of PVCOOL solar module. Also with heat sinks at rear the solar module operates cooler and produce more electricity. Solar modules with a flat rear surface can dissipate at rear side only 50% of all thermal power. Thermal energy can be used to cut energy costs and increase comfort levels in buildings at minor installation cost. On sunny winter days PVCOOL-SP95 solar module generates 95 Watts (peak) and 270 watts thermal heat power from the back surface. An installation of 1.9 kW (peak) PV array can generate extra of about 5 kW (peak) thermal power, average about 30kWh of low-grade heat can be collected on sunny day and transferred as tempered air into cool rooms to warm temperature.   In summer, this effect is reversible as cooling occurs at the back of the PV array, which faces the night sky as a radiant surface. In PVCOOL module, 4 times more thermal heat can be absorbed by rear heat sinks compared to flat rear modules. In non-cloudy nights, black color panels cool down at 5-7 degrees C below ambient air temperature due to the heat radiation to sky. Cooling air can be transferred to the living rooms to reduce air temperature. House designs can be made with underground storage facilities for accumulation thermal heat or cool energy with further use accumulated heat/cool energy in appropriate time.
