Solar panel warranties typically cover two main aspects: the performance warranty and the product warranty. Performance warranties guarantee that your solar panels will produce a certain level of electricity over a specified period, typically 25 to 30 years. If your panels don’t meet the promised performance levels, the manufacturer will usually replace or repair them. Product warranties, on the other hand, cover defects in materials and workmanship and are typically shorter, around 10 to 12 years. It’s crucial to review the warranties offered by your chosen solar panel manufacturer and installer to understand what is covered and for how long. Having strong warranties in place provides peace of mind and protects your solar investment.
