Wall Mounted Solar Metal Cabinet Warranty Period

Some solar warranties might last 20 years and only cover the product and labor costs, while other warranties might last 25 years and cover the product, system performance and labor costs. Don't be afraid to shop around to see who's offering the best deal. What's covered under a solar panel warranty?

Solar warranties are your safety net, shielding you from costly repairs and performance dips. Product warranties handle defects; performance warranties ensure energy output over time. Know the exclusions and avoid voiding your warranty with improper care or unauthorized fixes.

And if you plan to get a solar battery with your solar panel system, the battery is covered under a different warranty. The average battery warranty is 10 years. Your solar panel's performance warranty guarantees that your panels will produce a certain amount of electricity over the term of the warranty.

These warranties come in two main types: Product Warranties, which cover physical defects or failures in the panels, and Performance Warranties, which guarantee your panels will maintain a certain level of energy output over time. Why does this matter?

By the end of a typical 25-year warranty, your panels should still operate at 80-90% of their original capacity. Not all panels are created equal, though. Panels with lower degradation rates (closer to 0.5% per year or less) will generate more energy over their lifetime, saving you more in the long run.

Many homeowner insurers will cover roof-mounted solar panels as part of a regular homeowners insurance policy, though ground-mounted or carport systems may require supplemental insurance, according to a report from the National Renewable Energy Laboratory.
