For homeowners in San Gabriel, high electricity bills from Southern California Edison (SCE) are a familiar reality, especially during warm months. Rooftop solar offers a direct way to lower those costs, but the rules for getting value from solar have changed. In 2026, the key isn't just producing power—it's about using as much of that power as possible yourself. This makes understanding your options, especially the role of battery storage, more important than ever.

2026 Solar & Battery Cost Estimates in San Gabriel
Here are modeled cost estimates for a typical home, based on local pricing and a 7.1 kW system designed to offset a significant portion of a standard electricity bill. Note that the 30% federal tax credit for homeowners is no longer available for systems installed in 2026.
- Solar Panels Only: A 7.1 kW system is estimated to cost around $18,105. This setup is designed to produce power during the day to cover your home's immediate needs.
- Solar Panels + Battery: The same 7.1 kW system paired with a 10 kWh battery costs approximately $33,105. This configuration allows you to store excess solar energy for use in the evening, maximizing your savings.
These figures are benchmarks; your exact cost will depend on your roof, equipment choices, and installer.
Incentives & Tax Credits
California Solar Incentives for 2026
While the federal ITC for homeowners has expired, California still offers a crucial financial benefit that makes going solar attractive.
The most significant incentive is the Property Tax Exclusion for Active Solar Systems. This state rule means that adding a solar system will not increase your property taxes. Given San Gabriel's property values, this is a major benefit that can save you thousands over the system's lifespan. An owned solar system can also be a valuable feature that enhances your home's resale appeal to future buyers.
The primary financial driver, however, is avoiding SCE's high and escalating electricity rates, which provides a strong, ongoing return on your investment.

Net Billing (low export)

Understanding Export Rates with SCE Net Billing
Under California's current net billing tariff (often called NEM 3.0), the value of the solar energy you export to the grid is much lower than the price of electricity you buy from SCE.
When your panels generate more power than your home is using, that excess energy is sent to the grid. SCE buys this power from you at a modeled rate of around 11.3 cents per kWh. However, when you need to buy electricity from the grid (like at night), you pay the full retail rate of about 32.3 cents per kWh.
This difference is why battery storage is now strongly recommended. A battery lets you store your excess solar power instead of selling it for a low price. You can then use that stored energy in the evening, avoiding SCE's expensive peak rates and maximizing the value of every kilowatt-hour your panels produce.
Projected Savings
How Solar Translates to Bill Savings with SCE
High electricity rates from SCE mean that every kilowatt-hour of solar energy you use at home provides significant value. However, the savings potential differs greatly depending on whether you add a battery.
- With a solar-only system, you could see estimated annual savings of around $2,216, leading to a payback period of about 7.5 years. Savings primarily come from avoiding expensive daytime electricity purchases from SCE.
- Adding a battery storage system substantially increases your energy independence and savings. The estimated annual savings jump to $3,308, with a payback period of around 8.3 years. The battery allows you to avoid buying high-priced electricity from the grid during peak evening hours, which is why the annual savings are over $1,000 higher.
If utility rates continue to rise, the value of producing your own power will only increase over the life of the system.
