We had Sun watt installed our new solar system a few months ago. They were very thorough in details, and had many visits and meetings to make sure our needs would be met. The final result is beautiful and efficient! Highly recomended!

Frequently Asked Questions
Will a Sunwatt PV-only system provide power during an outage?
No. Sunwatt says a solar PV system without battery storage does not provide backup power during an outage.
Can Sunwatt add battery storage to an existing solar array?
In general, yes. The available options depend on the existing equipment and the homeowner’s backup needs.
What does a Sunwatt site evaluation include?
The team photographs details from attic rafters to the electric service and discusses system design, incentives and financing.
Can Sunwatt install solar on an older roof?
Sunwatt says it has installed on roofs five to ten years old after case-by-case inspection of the roof structure, decking and shingles.
