The TwinPower PV/Thermal
The TwinPower PV/Therma provides up to 300% more energy (in the form of solar electricity + solar heat) than a conventional solar PV system. The heat energy captured from the PV modules is circulated into the geyser system, pool heat and under ﬂoor heating system where it is used to displace the conventional heating load
The secondary beneﬁt is to provide PV cooling by reducing the operating temperature of the PV modules, which improves the electrical performance. Excess heat build-up behind PV panels is a common problem, and for every 1°C (1.8°F) above 25°C (77°F), the electrical output could drop by 0.4 to 0.5 percent.
more components and are more expensive than a standard grid-tied system as well.
