Synthesis of minute values

If required, the global radiation, which is supplied in hourly resolution, can be divided into minute values. In this process, 60 minute values are synthesized from each hourly value according to the Hofmann method.

Minute values of global radiation are particularly important in order to simulate yield losses due to inverter underdimensioning, inverter control or the interaction of PV system, consumers and storage systems as realistically as possible.
