For Home Solar + Roofing Customers Only Your solar system is covered by the 25-year Sunnova Protect warranty which is designed to reduce or eliminate out-of-pocket expenses for repairs. If any issues arise with your home solar system, contact Sunnova customer service at 866.SUNNOVA to report the issue. If you also had a new roof installed and need to report any issues with it, please contact your Sunnova dealer (listed as “Contractor” in your agreement) to report the issue. If you do not know your Sunnova dealer’s contact information, please contact Sunnova customer service by email at customerservice@sunnova.com or by phone at 866.SUNNOVA.
