Questions
Fairfield questions, answered
How many systems has Westhaven installed in Fairfield?
1,000+ installs in Fairfield as of August 2026. The count is real, pulled from our install records, and it grows most weeks.
Does Westhaven service Fairfield?
Yes. Fairfield is inside our core Northern California service area, reached by our in-house crews from Yuba City. We design, install, and service every system ourselves, and Power Guard monitoring watches each one around the clock.
Do I need a battery in Fairfield?
Most designs today include one. You store the power your roof makes and use it when rates are highest, instead of selling it to the grid for pennies. Backup during outages comes with it. We will show you the math for your address.
