What Solar Warranties Usually Cover
Most panels come with two kinds of coverage. A product warranty covers defects in materials and workmanship, often for 10 to 25 years. A performance warranty guarantees a minimum level of output over time, often for 25 years.
Where Cleaning Comes In
Installation and maintenance manuals commonly include cleaning guidance, such as how often to clean and what methods to avoid. Some warranties also exclude damage caused by improper maintenance or cleaning. The wording varies a lot between manufacturers, so we can't tell you what yours says. We'd rather you didn't assume either way.
How to Check Yours
- Find your warranty documents and panel manual. Your installer should have copies if you don't
- Look for sections on maintenance, cleaning and exclusions
- Ask your installer what the manufacturer expects and what records they recommend
- Keep your service invoices. A dated record of professional cleanings is easy proof of upkeep
Cleaning the Wrong Way Can Be the Bigger Risk
Abrasive pads, harsh chemicals, hard water and high-pressure spray can scratch coatings or leave residue. That kind of damage is the type warranties tend to exclude. It's also why hiring a professional who uses pure water makes sense. Our DIY vs. professional guide goes into more detail.
The Bottom Line
Check your paperwork, clean on a sensible schedule and keep the records. That protects both your output and your warranty position. For help picking a schedule, see our Sarasota cleaning schedule.
