Aim for companies with a solid reputation and a history of honoring their warranties.

What are common exclusions in solar power installation warranties?
Common exclusions in solar power installation warranties often include damages caused by natural disasters and improper maintenance. Understanding these exclusions can help homeowners avoid unexpected costs and ensure their solar systems remain protected under warranty.
