A faulty inverter or charge controller are the most likely reasons for a solar panel to register no voltage. Other possible reasons for low to zero power are a damaged PV module, poor wiring, shading and temperature higher than the ideal operating range. . According to the National Renewable Energy Laboratory (NREL), solar systems typically operate with over 95% reliability, meaning issues are usually preventable or easily diagnosed. This guide explains the most common reasons why your solar panels may not be generating power, and how to troubleshoot. . If a layer of dirt, dust, or grime has formed on your solar panels, it could be blocking sunlight and preventing your home solar panels from producing at their full power. You were sold on a specific level of performance, and if your system isn't meeting that promise, it's a major problem. It's fairly easy to clean solar panels or remove obstructions to get them back to their previous performance.
