Cost and savings sections below are sized to a typical system for this city’s average utility bill (~8.0 kW modeled). Typical monthly bill here: $319.77.

At this bill level, modeled system sizes are often in the mid-to-high single-digit kW range. Use the calculator below to match your actual usage.

With electricity rates from the Los Angeles Dept of Water & Power (LADWP) among the highest in the country, many Santa Monica homeowners are looking for ways to reduce their bills. Rooftop solar is a powerful tool, but the financial equation has changed. In 2026, the key to maximizing savings is using the solar energy you generate yourself, rather than selling it back to the grid for a low credit. This shift makes pairing solar panels with a home battery a practical and often more valuable strategy.

Benchmark Cost Analysis

Solar & Battery System Costs in Santa Monica (2026)

Here are modeled cost estimates for a typical 8.0 kW solar installation, designed to offset a monthly LADWP bill of around $320. These figures reflect pricing after the federal residential solar tax credit has expired.

  • Solar Panels Only: The estimated gross cost is around $20,400. This system is designed to produce energy during the day to power your home directly.
  • Solar Panels + 10 kWh Battery: The estimated gross cost for a combined system is $35,400. The battery stores excess solar energy generated during the day for you to use in the evening, significantly reducing your reliance on expensive grid power from LADWP.

An owned solar system can also be a strong selling point for future homebuyers, adding long-term value beyond the immediate bill savings.

Incentives & Tax Credits

California Solar Incentives for 2026

While the 30% federal tax credit is no longer available for systems installed in 2026, California homeowners still benefit from important state-level policies that support the economics of going solar.

  • Property Tax Exclusion: California law prevents your property taxes from increasing due to the added value of a solar energy system. This exclusion is a significant financial benefit that lasts for the life of the system.
  • High Rate Avoidance: The most powerful financial incentive is simply avoiding LADWP's steep electricity rates. Every kilowatt-hour of solar energy you produce and use at home is a kilowatt-hour you don't have to buy from the utility.

Understanding Export Rates with LADWP

Santa Monica operates under a net billing framework, which is different from older net metering policies. Here's what that means for your solar system:

  • Self-Consumption is High Value: The electricity your panels produce that you use immediately is worth the full retail rate you would have paid LADWP (around $0.323/kWh).
  • Exported Power is Low Value: Any excess solar energy you send back to the grid is credited at a much lower rate, estimated here at $0.113/kWh.

This structure is why a battery is so strongly recommended. Storing your excess solar power is far more valuable than selling it to the utility for pennies on the dollar. It allows you to use your own clean energy when the sun isn't shining, maximizing your financial return.

Projected Savings

How Much Can You Actually Save on Your LADWP Bill?

Your total savings depend on how much of your own solar energy you use. With LADWP's high retail rate of $0.323/kWh and a much lower modeled export credit of around $0.113/kWh, self-consumption is critical.

  • A solar-only system is modeled to save approximately $2,438 annually, with a payback period of about 7.7 years. Savings come from offsetting your daytime electricity usage.
  • Adding a 10 kWh battery increases the modeled annual savings to $3,657. The payback period is similar at 8.1 years, but the system provides far greater bill control and resilience. By storing solar power, you avoid buying expensive electricity from LADWP during peak evening hours.

These savings can become even more valuable over time if grid electricity costs continue to rise, making your rooftop-generated power a hedge against future price hikes.

Local Questions Answered

Why is a battery so important for solar in Santa Monica now?
Because LADWP credits you a low amount for exported solar energy. A battery lets you store your excess solar power to use in the evening instead of selling it cheap and buying it back expensive. This self-consumption strategy dramatically increases your savings.
Is solar still a good investment without the federal tax credit?
Yes, especially in areas with high electricity rates like Santa Monica. The payback period is still attractive at around 8 years, and the system protects you from future LADWP rate increases for decades. The California Property Tax Exclusion also provides significant savings.
How do I get a solar estimate for my specific home?
