Photovoltaic system

Photovoltaic systems (PV systems) consist of solar cells and can convert part of the solar radiation into electrical energy. This electricity can either be used directly at the point of generation, stored in a battery storage system or fed into the grid of the local utility provider. The profitability of a PV system depends strongly on the design and size of the system, the self-consumption (which is increased, for example, with a heat pump or an electric car) and the feed-in tariff for electricity fed into the grid. There are different forms of PV systems: on-roof systems, in-roof systems, solar tiles and solar facades. On-roof systems are installed on the roof by means of a mounting system, while in-roof systems, solar tiles and solar facades replace the weatherproof building envelope of the roof or facade. On-roof systems are easy to install and relatively inexpensive, while in-roof systems and solar tiles have aesthetic advantages and are particularly suitable if the roof is being comprehensively renovated anyway.
