What is your solar panel warranty?

A solar panel has two warranties: a performance and equipment guarantee. A solar panel’s performance warranty will typically guarantee 90% production at 10 years and 80% at 25-30 years. An equipment warranty will typically guarantee 10-12 years without failing.

A solar panel’s product warranty insurance covers the integrity of the panel itself and protects you against problems such as manufacturing defects, environmental issues, premature wear and tear etc. As with most warranties, a longer period is generally more advantageous to you, if you own your solar system When evaluating a solar panel warranty and its manufacturer, the two most important factors on which you should focus on are:

1. Product (or materials) warranty
2. The performance warranty

As to Lingtechsolar, the warranty policy is strict and completely.

Buyers can ask warranty policy paper from the sales person. And the warranty clause are along with order contract.
