Solar + storage in
Walnut Creek, CA.
Rossmoor is one of Northern California’s largest 55+ communities, and it accounts for a significant share of our work in Walnut Creek. Because of this, we are well-versed in the HOA’s Architectural Review Committee (ARC) approval process and can navigate it quickly. For the rest of Walnut Creek, the combination of large homes and monthly energy bills between $300 and $500 makes solar and battery storage one of the best financial decisions available.

What Walnut Creek homeowners need to know.
There are two important factors to know upfront regarding solar in Walnut Creek: the MCE CCA utility structure and the significant Rossmoor HOA community, which requires its own approval process. Neither of these factors acts as a barrier, but both will influence your project timeline. Here is the full picture.
Sun & production
Walnut Creek averages 5.5 peak sun hours per day, which is on par with the national average and consistent with the climate in central Contra Costa County. There are approximately 17,000 owner-occupied homes in the area, and neighborhoods such as Rossmoor, Northgate, Rudgear, Parkmead, Saranap, and Woodlands are all highly active for solar installations.
Your utility & rates
Most Walnut Creek residents are MCE (Marin Clean Energy) CCA customers, meaning that while PG&E delivers their electricity, their generation supply comes through MCE. NEM 3.0 applies regardless of this utility arrangement. Given that monthly bills often range from $300 to $500 due to large home sizes and high air conditioning usage, battery self-consumption during the 4 p.m. to 9 p.m. peak window delivers meaningful savings. Continuum designs every Walnut Creek system with MCE’s specific tariff structure in mind.
Rossmoor HOA & PSPS context
Rossmoor is a large 55+ active adult community in Walnut Creek with an Architectural Review Committee (ARC) process that every solar installation must complete before permits are pulled. Continuum manages the entire ARC submission and approval process for you. In other neighborhoods such as Rudgear and Northgate hills, residents face moderate exposure to Public Safety Power Shutoffs (PSPS). For these areas, battery backup is especially relevant for work-from-home households and individuals who rely on medical devices.
Rossmoor homeowners – we handle the HOA process: If you reside in Rossmoor, your solar project requires ARC approval before you can secure city permits. Continuum manages this entire process, including ARC documentation, submission, and follow-up, followed by the City of Walnut Creek permits and PG&E or MCE interconnection. You will have one point of contact from start to finish, and we will provide your full project timeline in writing before you commit.

Rossmoor ARC experience
We handle Rossmoor’s HOA ARC process as part of every Rossmoor project. Complete documentation the first time, faster approval, no surprises for homeowners navigating the process for the first time.
The Continuum difference: Most solar companies are unfamiliar with the ARC requirements in Rossmoor, leading them to submit incomplete packages that are often delayed or rejected. Because Continuum has extensive experience with this process, we prepare complete ARC documentation from the beginning. This results in faster approvals and no surprises during your project. We then manage your city permits and PG&E or MCE interconnection under the same fixed-price quote.
