One frequent question from homeowners is, “What kind of warranty do solar panels come with?” A solar energy system is a long-term investment, so knowing what’s covered can offer peace of mind. Here’s a quick breakdown of what to expect with solar warranties and why they’re essential.

Types of Solar Warranties

Most solar panels come with two types of warranties: product and performance. The product warranty covers defects or issues with the physical panels themselves, while the performance warranty guarantees that your panels will maintain a certain level of energy production over time.

Product Warranty: Peace of Mind for Panel Durability

A typical product warranty lasts around 10-12 years, though many high-quality panels now offer 20-25 years of coverage. This warranty protects you against issues like manufacturing defects, material faults, or premature wear. If a panel fails within this period, it’s typically replaced or repaired by the manufacturer.

Performance Warranty: Guaranteed Energy Production

Solar panels naturally lose a bit of efficiency each year, but a performance warranty ensures they won’t drop below a certain threshold—often 80-90%—over 25 years. This warranty gives you confidence that your panels will continue producing enough energy to meet your needs in the long run.

Inverter and Installation Warranties

In addition to panel warranties, the inverter (which converts solar energy into usable electricity) also comes with a separate warranty, typically lasting 10-15 years. Reputable installers may also offer an installation warranty (often 5-10 years) that covers issues related to installation, such as mounting problems or roof leaks.

Choosing Panels with Strong Warranties

Not all warranties are created equal, so it’s wise to choose panels from a manufacturer with a strong reputation and reliable warranty coverage. Good warranties can protect your investment and minimize costs if any issues arise.

Understanding solar warranties can help you make an informed choice and feel confident about your investment. Look for quality panels, solid warranties, and a trustworthy installer to enjoy your solar system worry-free for years to come.
