High electricity bills are a constant in San Francisco, but the rules for rooftop solar have changed. In 2026, simply sending excess solar power back to the grid doesn't provide the 1-for-1 credit it once did. This shift makes using your own solar power directly—a concept called self-consumption—the most effective way to save money. For homeowners in the Parkside neighborhood, this means a solar system paired with a battery is often the most practical path to meaningful energy savings.

Solar & Battery System Costs in Parkside (2026)
The following are modeled costs for a typical home in the Parkside area, based on an average electricity bill. These figures reflect pricing after the phase-out of the broad federal residential solar tax credit.
- Solar-Only System (4.7 kW): The estimated gross cost is around $11,985.
- Solar + Battery System (4.7 kW panels with 10 kWh battery): The estimated gross cost is $26,985. This configuration is recommended to maximize the value of your solar production.
These numbers are estimates; the calculator below can provide a more precise quote based on your specific home and energy usage.
Incentives & Tax Credits
California Solar Incentives for 2026
While the major federal tax credit is no longer available for most homeowners, California still offers important financial benefits that make solar a strong investment.
The most significant incentive is the Active Solar Energy System Property Tax Exclusion. This state rule prevents your property taxes from increasing because of the value added by your solar system. It's a crucial benefit, but note that the current program applies to systems installed through June 30, 2026.
Additionally, an owned solar system can be a compelling feature for potential homebuyers, potentially supporting your home's resale appeal. The primary financial driver, however, remains avoiding the high cost of grid electricity in the Bay Area.

Net Billing (low export)

How Export Credits Work in San Francisco
Under California's net billing structure, the value of the solar energy you produce depends on when you use it. Using your solar power in real-time to power your home is the most valuable approach, as it directly offsets electricity you would have bought for around $0.323 per kWh.
Any excess power you export to the grid is credited at a much lower rate, modeled here at approximately $0.113 per kWh. Because this export credit is less than half the price of buying power, storing your excess solar energy in a battery for later use is financially advantageous.
Projected Savings
Modeled Annual Electricity Savings
Adding a battery significantly increases your ability to offset expensive grid power. By storing solar energy generated during the day, you can use it during the evening instead of buying electricity at the full retail rate of over 32 cents per kWh.
- A solar-only system is projected to save approximately $1,219 annually, with an estimated payback period of 8.9 years.
- A solar and battery system increases the estimated annual savings to $1,739. While the payback period extends to 11.6 years, this setup provides greater bill control and resilience against power outages.
Long-term utility inflation can also improve the value of your solar investment over time. If grid electricity becomes more expensive in the future, the power your system generates becomes even more valuable.
