Quick Answer
Solar panels should be inspected for physical damage at least every 6 months, or after severe weather events, such as hurricanes or hail storms. This frequency helps prevent damage to the panels and the inverter, reducing the risk of electrical shock and equipment failure. Regular inspections also ensure optimal energy production.
Visual Inspection Techniques
When inspecting solar panels for physical damage, use a ladder or a lift to safely access the panels. Look for any signs of wear, such as cracked or broken glass, loose or missing screws, and damaged frame components. Use a flashlight to inspect the panels in the early morning or late evening when the sun is not directly overhead.
Frequency of Inspections
The National Renewable Energy Laboratory (NREL) recommends inspecting solar panels at least every 6 months. This frequency helps identify potential issues before they become major problems. If you live in an area prone to severe weather events, consider increasing the inspection frequency to every 3 months.
Additional Considerations
When inspecting solar panels, also check the mounting structure and the electrical connections. Make sure all connections are secure and not damaged. Clean the panels as needed to maintain optimal energy production. Use a soft-bristled brush and a mild detergent to clean the panels, and avoid using high-pressure washes or abrasive materials that can damage the panels.
