If you have several solar panels in your home, determine which ones don't function properly by doing a shading test.

Tighten the loose wires, take out the wires that have oxidation on them, and install new parts instead.

The system may overheat during the hottest and sunniest parts of the day. If the system produces less energy during the sunniest parts of the day, this is probably why. Inspect the wires and their connections, and repair any poor connections. If you find that some of the wires are very small, replace them with the heaviest wires that are compatible with the system.
