High electricity bills from Southern California Edison (SCE) are a constant pressure for homeowners in the San Gabriel Valley. With peak-hour rates getting more expensive each year, the old way of selling solar power back to the grid for a 1-for-1 credit is gone. Under California's Net Billing (NEM 3.0) tariff, your solar investment depends on being able to store and use your own power.
Benchmark Cost Analysis
What's the Real Cost for a Solar & Battery System in 2026?
To achieve energy independence from SCE, a combined solar and battery storage system is the standard for new installations. While a solar-only setup might seem tempting at around $8,050 after credits, its payback is severely limited by low export rates. The realistic and recommended path is a solar-plus-battery system.
- Gross System Cost: Approximately $23,500
- Federal Tax Credit (30%): -$7,050
- Net Cost After Incentives: $16,450
This investment covers a properly sized solar array and a battery, ensuring you can use your stored solar energy during SCE's expensive 4-9 PM peak rates, rather than selling it for pennies.
Incentives & Tax Credits
Key Financial Incentives for San Gabriel Homeowners
The primary incentive is the 30% Federal Residential Clean Energy Credit, which is locked in through 2032. This allows you to deduct $7,050 from your federal taxes on a $23,500 system. Additionally, California offers a full property tax exemption, meaning the significant value solar adds to your home won't increase your property taxes.

Critical 🔋
Understanding SCE's Net Billing (NEM 3.0)
NEM 3.0 is the policy that makes batteries essential. Under the old rules, SCE paid you a near-retail rate for any excess solar energy you exported. Now, they pay a fraction of that—around 5-8 cents per kWh. By storing that excess power in your battery instead, you can use it later to avoid buying electricity from SCE at peak rates (often over 40 cents per kWh). The battery transforms your system from a simple power generator into a tool for strategic energy management against SCE's time-of-use rates.
Projected Savings
Estimated Yearly Savings in San Gabriel
With an average electric bill of $243 and rising SCE rates, a solar and battery system delivers significant savings by maximizing self-consumption. Instead of just offsetting daytime usage, you're creating a private power reserve for nighttime use. Homeowners can expect to eliminate over 70% of their utility bill, resulting in an estimated $1,726 in annual savings. This leads to a typical system payback period of around 9 to 10 years—an investment that continues to pay dividends for over two decades.
