If your solar panels are not working, check the circuit breaker box. Some switches might have been turned off or broken. Check your inverter's indicator lights first – a green light means normal operation, while red or orange signals a potential issue requiring attention. Like any other technology, solar systems can also malfunction or underperform in certain conditions or due to various issues. Checking Voc (voltage open circuit) and Isc (current short circuit) measurements can help diagnose panel issues. Loose connectors and improperly seated terminals can cause low voltage or current. . Real-world performance expectations: Solar panels typically achieve only 75-85% of their rated capacity under normal conditions due to temperature effects, inverter losses, and varying weather patterns—this is completely normal and not a sign of system failure. Soiling is the #1 culprit: Dirt. . Obstructions, dirt, a faulty inverter, or broken panels could be why your solar panels aren't working.
