TechnologyCoolPV is a hybrid PV module which adds the collector to the PV module to produce both electricity and hot water.
CoolPV generates up to 4 times more energy than conventional PV modules because it gathers the remaining solar energy from the solar power generation through its collectors. The circulating water flowing into the collector cools the PV and produces more power. PV module and collector are all-in-one design that enables applications where the floor area is limited, and the polymer material collector is very light to transport and install easily.
