How Good Warranties Actually Work (And What to Watch For)

Warranty categories

Panel performance (long-term output expectations)
Product/workmanship (defects)
Inverter coverage (often shorter than panels)
Racking coverage (corrosion and structural)

What to watch

Who handles claims?
Is labor included or only parts?
Is the company likely to be around?
Are serial numbers and install docs required?

DIY tip

Keep a "system folder" with receipts, spec sheets, and photos.

Next step: Choose brands that make warranty claims realistic, not theoretical.
