What Maintenance Should Be Done After Extreme Weather?

Inspecting Solar Panel Damage

Inspect solar panels for any visible damage, such as cracks, broken glass, or misaligned frames. Use a ladder or a lift to safely access the panels. Check the panel’s frame and mounting system for any signs of looseness or damage. If any damage is found, replace the affected panels or have them repaired by a professional.

Cleaning Solar Panels

Solar panels should be cleaned every 6-12 months, or more frequently if they are exposed to heavy dust, debris, or bird droppings. Use a soft-bristled brush or a specialized solar panel cleaning cloth to gently remove dirt and debris. Avoid using high-pressure washes, abrasive cleaners, or bleach, as they can damage the panels’ surface or compromise their electrical performance. For more thorough cleaning, mix 1 cup of white vinegar with 1 gallon of water in a spray bottle and spray it onto the panels, then wipe clean with a soft cloth.

Verifying System Functionality

After extreme weather, verify the functionality of the charge controller and the electrical connections. Check the charge controller’s settings and ensure it is set to the correct voltage and current limits. Inspect the electrical connections, including the wiring, fuses, and connectors, for any signs of damage or wear. Use a multimeter to test the voltage and current output of the solar panels and the charge controller to ensure everything is functioning within the manufacturer’s specifications.
