Enhanced Solar Electric and Solar Pool Heating System in One

Combination Pool and PV Systems

The world’s newest and most elegant Solar Energy Solution has finally arrived. CoolPV is not your typical residential solar PV system. CoolPV is a premium solar electric system that generates electricity and heats water using the same panel on the same roof space. Because the solar electric panel is “cooled” CoolPV can generate up to 4x the energy than that of a stand alone Solar Electric System!
