Even the most efficient solar systems face inevitable PV loss. These include losses in solar cell conversion, inverter power loss, and resistive wiring losses. Typically, approximately what percentage of PV power is expected to be lost through the wiring? The answer is about 2–3%. That means energy is lost as it moves from the panels to the inverter. More losses in the PV system occur... https://solarsme.com/top-solar-energy-system-losses/
