Thermal solar collectors

Thermal solar collectors can absorb the sun’s rays and convert them into heat. This heat is stored in heat storage tanks and can then be used to heat the hot water, to support the heating or to regenerate the geothermal probes. In contrast to the electricity feed-in option with a PV system, the excess heat cannot be used or sold with thermal collectors. Another disadvantage compared to the PV system is the more complex maintenance. In addition, it often makes more economic sense to generate hot water by means of a heat pump and PV system than thermal solar collectors directly.
