The exterior part of your solar panel system contains mounting hardware, solar panels, and wired connections. Exterior maintenance is a question of cleanliness and protection against elemental damage.

The following is a step process for completing it:

Check your lightweight solar plate for cracks in the glass or Plexiglas panel. If cracks are detected, cover with high-temperature silicone products.

Cracks can allow moisture, and they can also grow deeper and wider if left untreated. Be sure to clean the area around the gap with a window cleaner and dry it thoroughly before applying silicone. It's best to work on cracks when the sun is low and the glass isn't too hot.

Clean the dirt, grime, bird droppings, and other foreign matter from the solar panel, then wash everything with a window cleaning solution or vinegar and water solution.

Check all mounting hardware to make sure your solar panels are still tight. You can spray the WD-40 thin film on the connection if they show signs of exposure to the elements. Replace seriously corroded hardware.

Also inspect the bolts that go into your roof and apply the roof seal to the bolt head and around the hole, if necessary.

Check the wire connector that leads from your solar panel to your home for any signs of corrosion or collapse. Replace damaged cables or connectors.
