The Fraunhofer Institute for Solar Energy Systems ISE, a Germany-based research body, has developed the a method for quantifying PV self-consumption. Research scientists have now published their findings in an analysis prepared for the German Federal Environment Agency. The economically motivated self-consumption of solar power has been rising sharply in Germany since the feed-in tariff relationship reversal. In 2024, self-consumption totalled 12.28 TWh, representing 17% of PV-based net electricity generation. This 17% share reflects improvement from its value in 2023, when the share remained at 13%. Researchers anticipate that self-consumption will continue to rise supported by elevated electricity costs and wider BESS integration. Prior to this update, Fraunhofer ISE was studying medium-voltage approaches to improve efficiency.
