With average electricity bills in San Pedro climbing toward $320 a month, finding ways to lower costs is a top priority for many homeowners. Rooftop solar is a powerful tool for reducing your reliance on Los Angeles Department of Water and Power (LADWP), but the rules for 2026 place a strong emphasis on using the energy you produce. Understanding how to maximize your savings under LADWP's compensation structure is the key to making a smart investment.

How Much Do Solar Panels Cost in San Pedro?
The upfront investment for a solar system in 2026 depends heavily on whether you include a home battery. For a home in San Pedro needing an 8.0 kW system to offset a high electricity bill, the estimated costs are as follows:
- Solar-Only System Cost: The estimated gross cost is $20,400.
- Solar + Battery System Cost: To maximize savings and add blackout protection, a system with a 10 kWh battery has an estimated gross cost of $35,400.
Since the 30% federal tax credit is no longer available for new systems, this gross cost reflects the total investment. However, an owned solar system can add value beyond bill savings by enhancing your home's resale appeal in the competitive Los Angeles market.
Incentives & Tax Credits
Key California Solar Incentive for 2026
While federal tax credits for homeowners have expired, California offers a crucial incentive that protects your investment:
- Property Tax Exclusion: When you install a solar energy system on your home, its value is excluded from your property tax assessment. This means you get the benefit of a home improvement that saves you money every month without the downside of a higher tax bill. This exclusion is a significant, long-term financial benefit for California homeowners.

How LADWP Compensates for Your Surplus Solar
LADWP, like many California utilities, has a net billing program where the credit you receive for surplus solar energy sent to the grid is less than the price you pay for electricity. For example, you might pay LADWP $0.32/kWh for power you use at night, while the excess solar you generate mid-day may only earn you a credit of around $0.11/kWh.
This difference in value makes self-consumption critical. A solar battery allows you to store your low-cost solar energy and use it later, ensuring you get the full retail value from every kilowatt-hour you produce. It's the most effective way to reduce what you owe LADWP each month.
Projected Savings
Projected Solar Savings with LADWP Rates
In San Pedro, the financial benefit of solar comes from avoiding LADWP's high electricity rates, which are modeled here at over $0.32 per kWh. Adding a battery dramatically improves your ability to do this, leading to significantly higher savings with a minimal impact on the payback time.
- A solar-only 8.0 kW system is modeled to save an estimated $2,438 annually, with a payback period of about 7.7 years.
- Adding a battery to that same system boosts the estimated annual savings to $3,657. The payback period only increases slightly to 8.1 years, making the solar-plus-battery option a very compelling financial choice for maximizing long-term value.
As utility rates continue to face upward pressure, generating your own power provides a valuable hedge against future price hikes.
