A solar electricity plant means profitable power generation with a good conscience.

The electricity is free as soon as the PV system has paid off. Up till then, every kilowatt hour fed in by the local energy provider is refunded. So it is important to have systems run as long as possible – over several decades – with good performance. SES 21 provides a special service portfolio with well engineered products and first-class consulting services for this.

Photovoltaics systems produce electricity from sunlight. (1) They consist of solar modules with semiconductor elements. They have to be installed safely on a substructure for the long term and will defy any kind of weather. (2) Inverters convert the direct current generated into alternating current that can be fed into the public grid (3) measured by (4) power counter.

The overall level of efficiency of a power station is decided by the carefully coordinated interaction of the system components (solar modules, inverter, etc.). An important element for the operation of the PV system is the continuous performance monitoring with modern software.
