What is different about going solar in Kensington
County permits
Kensington is unincorporated, so solar and battery permits go through Contra Costa County. We prepare and file everything.
Shade and slope
Tall trees and steep, multi-level roofs are common here. Microinverters like Enphase handle partial shade better, which is one reason we use them on many Kensington homes.
Backup for the hills
Hillside neighborhoods can see outages during storms and fire weather. A battery keeps the essentials running and gives you power at night.

Our story
Ally is a family-owned solar and electrical contractor in Richmond. Our team was first licensed in 2002 as Arco Electric, and in 2010 we became Ally Electric & Solar. Since then our own crew has helped more than 1,000 Bay Area homeowners, and in 2026 our neighbors voted us a Nextdoor Fave. Some customers have been with us a long time: the Garafolis in Oakland have been saving on their electricity bill since 2016.
"They made sure all PGE paperwork, issues and questions were addressed quickly."
Kensington solar questions
Who issues solar permits in Kensington?
Contra Costa County, because Kensington is unincorporated. We file the permit and schedule the county inspection.
What works best with tree shade?
Panels with microinverters, like Enphase, let each panel work on its own, so shade on one panel does not drag down the rest. We check shade on site before we design.
Can I add a battery to an existing Kensington system?
Yes. We add Enphase, Tesla Powerwall 3 and FranklinWH batteries to existing systems. See solar expansions.
How much does a home battery cost in Kensington?
Battery systems start from $15,000 installed, before rebates. The final price depends on panel upgrades, wire runs and how many batteries you want. GoGreen financing is available.
Is Ally licensed for both solar and electrical work?
Yes. Ally Electric & Solar holds CSLB license #806465 with C-10 (electrical) and C-46 (solar) classifications. Our team has been licensed since 2002, and Ally has been in business since 2010.
