It can cost anywhere from $200 to $400 to fix a solar panel, but the repair cost may be more if you have a warranty. One way to determine whether or not your solar panels need repairing is to inspect them for broken or cracked glass, as well as any signs of water leakage. If you do spot any problems, take some photos and contact your solar installer right away for assistance. Many solar companies will offer free or discounted repairs if you have a warranty agreement in place.

It can cost anywhere from $0 (if you're handy and can do it yourself) to hundreds of dollars, depending on the extent of the damage and the company you hire to do the repairs. If your solar panels are damaged but still producing electricity, you may be able to get away with only cleaning them. This involves using a hose or a pressure washer to remove any dirt, debris, or bird droppings that have built up on the panels. You should also check for any broken or missing panels, and replace them if necessary. If your solar panels are not producing electricity, then you'll need to have them repaired or replaced.
