Solar Services in Sunnyvale, CA

Professional Solar Solutions for Residential & Commercial Properties

Sunnyvale electricity service may involve Silicon Valley Clean Energy for generation and PG&E for delivery, billing, and grid services. That local rate structure drives most of the solar conversations we have with Sunnyvale property owners. Add in a housing stock that ranges from single-family homes to HOA-governed townhome communities, plus a dense concentration of tech and light-industrial buildings, and you get a market where a generic solar package rarely fits. Cobalt Power Systems Inc has designed and installed solar systems throughout the Bay Area since 2003, completing more than 3,500 photovoltaic installations, and Sunnyvale’s mix of property types is exactly the kind of variety our in-house design team is built to handle.

Solar under PG&E’s Current Rate Structure

Most new solar systems in California, including everything we design in Sunnyvale, fall under the Solar Billing Plan, also known as the Net Billing Tariff or NEM 3.0. Under this structure, power you export back to the grid receives a credit at a lower rate than it used to. That changes the math: instead of designing a system to maximize what you sell back to PG&E, we design it to maximize what you use yourself, which is why battery storage has become an important consideration for many Sunnyvale homeowners going solar today.

A battery stores what your panels produce during the day and releases it during PG&E’s more expensive evening hours, when rates are highest and grid demand peaks. For many Sunnyvale households, using stored energy during those peak periods can represent a meaningful portion of the monthly value a solar-plus-storage system provides. Because utility rates, export credits, and rate-plan rules can change, we review your specific energy use, system design, and storage options during the consultation so the analysis reflects your property’s actual conditions.

What Makes Sunnyvale Different: A few things about this market change how we approach a project here:

• HOA design review. Some Sunnyvale properties sit inside HOA-governed communities with specific rules on panel visibility and placement. When that applies, we build those requirements into the layout before submitting anything, so you’re not redesigning after a rejection.
• Commercial density. Sunnyvale’s office and light-industrial properties can have varied daytime energy loads and EV charging needs, and we size systems around those actual load profiles.
• Housing variety. Shingle, tile, and flat commercial roofs all show up regularly across Sunnyvale, and our design team sizes systems around your property's configuration rather than a standard assumption.
• City permitting and PG&E interconnection. Sunnyvale photovoltaic projects require city permitting before installation, and eligible small residential systems may qualify for expedited review.

Why Sunnyvale Property Owners Choose Cobalt Power Systems Inc

We’ve completed more than 3,500 photovoltaic installations across the Bay Area, and Sunnyvale’s property mix, from HOA townhomes to commercial rooftops, is squarely within that experience. We are the first SunPower Elite Dealer and have been named SunPower Dealer of the Year. We’re also a Tesla Premier Certified Installer and a Maxeon Preferred Partner, and we work closely with Enphase and QCells, so you’re choosing from proven equipment rather than an unfamiliar brand.

Every residential installation includes a 15-year materials and labor warranty, and we’re fully bonded and insured. We also provide complimentary system checkups and panel cleanings for residential customers after the first year in operation. Design, permitting, and installation all happen in-house from our 10,000-square-foot Mountain View facility, with 14 installation teams and 32 service trucks, so a design revision doesn’t mean waiting on a subcontractor’s schedule.

Getting Started

A free consultation is the starting point. We review your PG&E bill history, walk your roof or site, and talk through HOA requirements if they apply to your property. From there, our CAD team builds a layout sized to your roof, shading, and panel capacity, and we handle City of Sunnyvale permitting along with PG&E interconnection coordination. Once the system is installed and approved, we walk you through monitoring so you can see exactly how it’s performing.
