When solar radiation passes through the glass cover and penetrates
the PV layer, most of the radiation is absorbed by the PV cells
and the black TPT layer. Part of this radiation is converted into electricity,
and the rest is eventually converted to heat energy. The
electricity is transported by a solar controller to the electricity consumer
or to an accumulator battery. Heat energy is conducted
along the aluminum plate to the evaporator section of the heat
pipes. The heat pipes then transfer this energy to the water flowing
through the water box through the condenser sections.
