How to extend commercial solar panels warranty?
To extend commercial solar panels's warranty, customers should have full knowledge of our warranty policy specified in the contracts signed by both parties. We regulate the warranty range, services provided, and conditions for compensation. As our product performance and style are rapidly updated, sometimes it is not necessary to require repair or replacement in a high frequency. If customers confirm to extend the warranty, contact our after-sales personnel for help who will give you a detailed explanation about the procedures and cautions.
