Solar panel warranties - How do they work?
How do solar companies fulfill their warranties? Do they change one panel if it breaks or is underperforming? How long will my system be out of commission if this happens?

When my array got destroyed by a tree, the homeowners insurance covered it. For my Sunpower panels, I believe they'd be replaced if they don't produce 80% of the original production during the first 25 years. That would be rare though.
