Understanding the warranty offered by a solar installation company is crucial in choosing the right Solar Installer.

When it comes to warranty, this is one of the most important things that you need when comparing solar proposals.

There are 2 types of warranties that the solar installers offer. Product Warranty and Performance Warranty.

Product Warranty

Product Warranty covers the integrity of the panel. Any defect in materials, manufacturing and premature wear and tear is covered by the warranty. Most solar panel manufacturers warrant that their solar panels and will not fail for at least 10-12 years with some even extending to 25 years. Remember, the longer the warranty period is, the more advantageous it is to you as a customer.

Performance Warranty

Performance Warranty, on the other hand, this warranty covers the degradation rate of power output the panel can provide over time. A common practice in the solar energy industry is guaranteeing that the panels will produce electricity at 80-90% of their power output ratings. This means that the manufacturer guarantees that the panel will not lose 10-20% of their power output capacity over the 25-year period.
