What is PVT Solar Collector?

These are systems that convert solar radiation into thermal and electrical energy. These systems combine a solar cell, which converts sunlight into electricity, with a solar thermal collector, which captures the remaining energy and removes waste heat from the PV module.

Two types of PVT Solar CollectorWater PVT CollectorAir PVT Collector

Water PVT CollectorIn a standard fluid based system, a working fluid, typically water, glycol or mineral oil is then piped through these pipes or plate chillers. The heat from the PV cells are conducted through the metal and absorbed by the working fluid (presuming that the working fluid is cooler than the operating temperature of the cells).

Advantage The basic advantage of this type of split configuration is that the thermal collector and the photovoltaic collector can operate at different temperatures.
