ELECTRICAL PERFORMANCE OF A WATER-COOLED PVT SYSTEM WITH FORCED AND NATURAL CIRCULATION

This study evaluated the electrical performance of a photovoltaic-thermal (PVT) system using water as cooling fluid (PVT/w), with adaptation, in photovoltaic module device for heating without direct contact cell and air secondary working fluid. The PVT/w forced natural circulation was compared regime thermal accumulation hot supply by boiler reservoir relative to same PV panel original factory characteristics. average temperature, open circuit voltage, current voltage load, generated electric power were analyzed during seven non-consecutive days, ten repetitions every thirty minutes between 9:30 am 2:00 pm city Dourados-MS, Brazil, June July 2021. PVT (PVT/w_CB) presented best (PVT/w_SB), order 3.7%.
