Solar collector system is a set of technical devices that absorb solar radiation by converting it into heat, which is transferred to a solar boiler or through heat exchangers in a swimming pool, underfloor heating or other heat accumulator.

The construction principle of the solar collector is relatively simple - it consists of a housing, an absorbent surface, a layer of thermal insulation and impact-resistant solar glass. Copper pipes are placed in the housing below the absorbent surface, through which the heat carrier flows, which for safety reasons must not be antifreeze or other toxic liquid.
