Solar Installation in Walnut Creek, California
Walnut Creek homes tend to be larger and better insulated than the county average, and the systems we design here are correspondingly bigger.

Designed around your roof, not a template
Singh Solar Couple is a family-run solar company based in Concord, Contra Costa County. We design and project-manage residential and commercial solar, battery storage and EV charging for homeowners in Walnut Creek. You deal directly with the owners from the first call to switch-on.
Mixed stock, from Rossmoor single-storey units to large Northgate and Saranap homes. Tree cover is heavy in parts of Walnut Creek, so a shading study matters more here than in flatter neighbouring cities.
What solar costs in Walnut Creek
Walnut Creek is served by PG&E for electricity delivery, with generation supplied by MCE, the local Community Choice Aggregator. That matters because PG&E residential rates are among the highest in the United States, and because it puts Walnut Creek under the California Public Utilities Commission's Net Billing Tariff — the rules commonly called NEM 3.0.
We won't quote you a price on a web page. System cost depends on your actual usage, your roof and whether you add storage, and any installer who gives you a figure before seeing your bill is guessing. What we will do is model your real numbers against current rates and show you the working — including the Contra Costa County permit and inspection costs that City of Walnut Creek Building Division charges, which some quotes leave out and bill later.
Why Walnut Creek homeowners are adding batteries
Under the Net Billing Tariff, the credit you earn for exporting surplus solar to the grid is far lower than the retail rate you pay to import it. The practical consequence is that a system designed to export as much as possible no longer pays the way it did — the value now comes from using your own power, especially during expensive evening peak hours. That shifts what a good design looks like in Walnut Creek specifically, because the roof determines how much midday surplus there is to store in the first place: mixed stock, from Rossmoor single-storey units to large Northgate and Saranap homes. Tree cover is heavy in parts of Walnut Creek, so a shading study matters more here than in flatter neighbouring cities.
That is why most of the systems we design in Walnut Creek now include storage, and why we size the battery to your evening load rather than selling you the largest one available. A battery also keeps your power on during an outage, which a grid-tied system without one cannot do.
Every documented install is listed on our completed projects page, with system sizes and real timelines.

Permits and inspection in Walnut Creek
Solar permits for Walnut Creek go through the City of Walnut Creek Building Division. Under California Senate Bill 379, jurisdictions of this size have been required since 2023 to offer online permitting that issues a residential solar and storage permit — up to 38.4 kW AC — in real time rather than over weeks.
We manage the application to City of Walnut Creek Building Division, the PG&E interconnection paperwork and the inspection scheduling, and the installation is carried out by our licensed contractor partners. You do not need to speak to City of Walnut Creek Building Division or to PG&E yourself; that is our job.
