A photovoltaic system is an electricity producer – i.e. your own small power plant on the roof It does not produce any harmful substances and, at the same time, is easy on the purse as the dependency on fossil raw materials and thus on expensive electricity decreases. Annually, the sun emits an energy quantity of approx. 1,000 kilowatts per square metre in Germany. This energy potential corresponds to approx. 100 litres of heating oil or 100 cubic metres of natural gas.
The correct roof pitch is the prerequisite for optimum use A south-oriented surface is ideal. However, a deviation to southwest/southeast only decreases the energy yield slightly. In contrast, shade must be avoided or excluded with PV systems. Due to shade, individual modules can generate no or only a low level of electricity, which could affect the system's overall performance considerably. The easiest way to find out the roof pitch is examining the construction plans. Alternatively, the inclinometer can be used. If you are interested, we would be happy to advise you accordingly.
