Even higher energy yields The »PV-Therm« combined module is the answer to a physical problem: The higher the temperature of the photovoltaic modules, the lower their output, in other words, under the very conditions in which they ought to be most effective. With each degree rise in temperature, they lose approx. 0.5% of their performance. At the latest in summer, when the solar cells heat up to 80°C, this will become a problem. The »PV-Therm«, developed by us, is different. A so-called heat transfer fluid flows through an additionally installed steel tub in order to cool the solar cells. It is connected to the photovoltaic laminate by means of an as of yet unique polyurethane enclosure – which ensures optimum density and resistance.

And additional options Because »PV-Therm« can even do more. If a fluid is used for cooling, it will need to be heated – and can thus be used otherwise. After all, heat is appreciated elsewhere, e.g. for hot water generation and as heating support. Thus, the aspects of thermal solar collectors and photovoltaic modules, which have always been separate, are combined in one product. What usually decreases efficiency is now useful in two ways. If necessary, the solar thermal water circulation can be used for the safe removal of snow or de-icing of modules in winter.
