Thinking about solar panels for your home in San Bruno? With high PG&E rates, generating your own electricity is an effective way to lower monthly expenses. But as of 2026, the financial equation has evolved. The federal tax credit that many homeowners relied on is no longer available, and PG&E's rules now place a higher value on using your solar power at home rather than exporting it.
This guide breaks down the modeled costs, savings, and key considerations for going solar in San Bruno today, including the important role a home battery can play in maximizing your investment.

What Do Solar Panels Cost in San Bruno in 2026?
Here are modeled price points for a typical solar installation in the San Bruno area, reflecting costs without the previous 30% federal tax credit.
- Solar Only (4.7 kW System): The estimated upfront cost is $11,985. This system is sized to cover the electricity needs of an average local home.
- Solar + Battery (4.7 kW System with 10 kWh Storage): Adding a battery brings the estimated total cost to $26,985. This option provides energy independence and higher long-term savings by storing solar power for nighttime use.
These figures are estimates based on local averages. Your actual cost will vary based on the equipment you choose and your home's specific characteristics.
Incentives & Tax Credits
Key Financial Benefits for San Bruno Homeowners
Even without a federal tax credit in 2026, California provides important incentives that make solar a strong financial decision:
- Property Tax Exclusion: Installing solar panels will not increase your property taxes in San Mateo County. California's solar property tax exclusion ensures your home's assessed value doesn't rise due to the panels, a benefit that saves you money every year.
- High Rate Offset: The primary financial driver for solar is offsetting PG&E's high electricity rates. The more you can self-consume your solar power, the greater your savings, effectively giving you a high return on your investment.

PG&E's Net Billing: Why Self-Consumption is Key
Under the current rules, PG&E pays you a low rate for any surplus solar energy you send to the grid. This model estimates that export credit at just $0.113 per kWh—far less than the $0.323 per kWh it costs to buy electricity. This difference makes it financially smart to use as much of your own solar power as possible.
A battery is the best tool for this. It stores the extra energy your panels produce during sunny afternoons, letting you power your home with it in the evening instead of selling it to PG&E for a low price and buying it back for a high one. It also provides valuable backup power during grid outages.
Projected Savings
Modeled Savings with PG&E
Your potential savings depend on how much of your own solar power you can consume directly. With PG&E's retail rate at $0.323/kWh, replacing grid power offers significant value.
- The solar-only system is modeled to save a San Bruno homeowner about $1,354 in the first year, with a payback estimate of 8.1 years.
- The solar-plus-battery system increases those annual savings to $1,952. By avoiding low-value exports and expensive evening electricity from PG&E, the battery boosts your financial return. However, the higher initial cost extends the modeled payback period to 10.6 years.
Beyond monthly savings, an owned solar system can also become more valuable if grid electricity costs continue to rise, offering a hedge against future rate hikes.
