How to Test Insulation Resistance on Solar Panels
Testing the insulation resistance of solar panels is a critical procedure to ensure the safety, reliability, and efficiency of a photovoltaic (PV) system. Proper insulation prevents leakage currents, which can degrade performance and pose safety risks. This guide provides a comprehensive overview of how to perform insulation resistance testing on solar panels. Key Considerations for Insulation Resistance Testing When measuring the insulation resistance of a solar panel that is actively generating electricity, it is essential to avoid using conventional methods designed for standard circuits. The voltage generated by photovoltaic cells can influence the test voltage, and if the array is grounded, there is a risk of damaging connected equipment. Using specialized tools designed for PV systems can mitigate these risks by accurately measuring insulation resistance without interference from the PV system’s generated electricity. Step-by-Step Procedure for PV Insulation Resistance Testing Follo…
