Multivariant Analysis of Photovoltaic Performance with Consideration of Self-Consumption

The presented work contains the comparison of a different photovoltaic system approach, in terms monthly energy production profiles, with detailed user needs profiles. Two types investors were taken into account—a company where yearly consumption exceeded 50 MWh and standard household was around 6 MWh. Moreover, two scenarios considered; first one focused on maximization during year by choosing optimal azimuth tilt angles, whereas second PV based East–West which usually enables to have better self-consumption, leads sustainable usage. Energy along users’ analyzed sustainability, investment payback time, loss face new Polish Renewable Law. Recent changes Law Poland, came force 1 April 2022, changed way many are thinking about investing systems. main difference is how Distributor obliged trade electrical injected grid Prosumers. so-called “net metering”, kind barter deal, billing”—selling at wholesale price. Net billing believed be less profitable than net metering due significant price between bought sold energy.
