Where We Work

Six regions across the Northern California valley and foothills, each with its own utility rules and its own reasons to go solar.

How our map works

Six regions, one small team

Your power provider decides more about your system than almost anything else, so we organize by who serves you.

Utilities change by street

SMUD, PG&E, Roseville Electric, Lodi Electric and several community energy agencies all operate on our map. Each has its own paperwork and its own credit for what you send back.

Incentives are local

A battery rebate that is generous in one county does not exist two towns over. We quote against the programs your address can actually use.

Same crew everywhere

No franchises and no subcontracted sales offices. The people who design your system are the people who show up to build it.

What stays the same

What you get in every region

The region changes. The way we work does not.

A design, not a sales pitch

You get a layout, an honest production estimate and the tradeoffs explained. No pressure, no call center, no commission theater.

One trip for the whole job

Roof work, electrical work, storage and inspection are sequenced by one team so nothing gets torn out and redone.

Warranty we answer for

Twenty-five-year premium panel coverage from the manufacturer and ten years of workmanship from us, in writing.

Outside these cities

Don’t see your city? Call us.

The cities below are where we work most, not a fence around the map. If you are a reasonable drive from any of these regions, call us at 510-773-1922 and we will tell you straight away whether we can take the job. If it is too far to service properly, we will say so instead of wasting your afternoon.

We quote by address, because the utility, the incentive programs and the permit office all depend on exactly where the house sits.

Before you call

Questions about our service area

How do I know which region I am in?

Find your city in the cards above. If it is not listed, call and tell us your town, and we will point you to the closest region or tell you it is out of range.

Do you charge more for towns further out?

Travel is part of how we price any job, and we tell you the number before you commit. There is no surprise mileage line added later.

Why does the utility matter so much?

It sets what your extra power is worth, what rebates exist and how long interconnection takes. Two identical houses in different territories get different designs.

Can you work on a home I own but do not live in?

Yes, as long as you are the owner or have written owner authorization, since permits and interconnection are filed in the property owner’s name.
