The lower the temperature of the photovoltaic module, the higher their output. This is a problem, especially in summer when outside temperatures are high. When the solar cells heat up, it inevitably leads to loss in performance. What is therefore, more obvious than to cool the modules in order to increase efficiency? This is precisely the secret of the PV-Therm module: it is cooled using a heat transfer fluid - thus increasing output. But there is more: at the same time, the heat generated through the cooling process can also be used, e.g. for water heating or to support heating systems.
