The antifreeze flowed on the back side keeps the solar cell at a low temperature, which does not rise above the ideal temperature even in hot weather, therefore increasing the power generation capacity of the solar cell by at least 25%, while hot water can be produced from the released heat.
The flat collector unit is more than half the heat generator has the same capacity as a flat collector of similar size.

Hybrid solar panel

The hybrid module has a double function - It produces electricity and heats water.
The first part of the collector has the polycrystalline solar cell, which produces electricity and unfortunately heats up in the process. Heating significantly reduces its efficiency.
A flat collector is integrated on the rear surface, which absorbs the heat and cools the solar panel.
Thus increases the performance of the solar panel while producing hot water like a traditional solar collector.
