Photovoltaic systems

Solar power systems generate electrical energy from sunlight. Their output curve follows the daily path of the sun; the highest yield is achieved around midday. The daily consumption peaks in the electricity grid also occur at around the same time.

Due to the current feed-in tariffs, it makes sense to use all the electricity yourself. The size of grid-connected systems is primarily determined by economic and legal factors. In addition to the investment costs and the available space, the statics of the roofs play a key role for existing systems.
