Solar Installation in Brentwood, California
Brentwood was farmland thirty years ago and is now one of the fastest-grown cities in Contra Costa, which means an unusual amount of newer roof that is straightforward to work on.
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 Brentwood. You deal directly with the owners from the first call to switch-on.
Most of the housing went up between 1990 and 2008 on former orchards and farmland, so roof planes are consistent, pitches are predictable and the structures are new enough that reinforcement is rarely needed. Like Antioch, Brentwood is not an MCE community — generation and delivery both come from PG&E. Summer temperatures out here run well above the central county, so cooling load drives the sizing.
What solar costs in Brentwood
Brentwood is served by PG&E for electricity delivery. That matters because PG&E residential rates are among the highest in the United States, and because it puts Brentwood 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 Brentwood Building Division charges, which some quotes leave out and bill later.
Why Brentwood 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 Brentwood specifically, because the roof determines how much midday surplus there is to store in the first place: most of the housing went up between 1990 and 2008 on former orchards and farmland, so roof planes are consistent, pitches are predictable and the structures are new enough that reinforcement is rarely needed. Like Antioch, Brentwood is not an MCE community — generation and delivery both come from PG&E. Summer temperatures out here run well above the central county, so cooling load drives the sizing.
That is why most of the systems we design in Brentwood 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 Brentwood
Solar permits for Brentwood go through the City of Brentwood 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 Brentwood 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 Brentwood Building Division or to PG&E yourself; that is our job.
