Facing High LADWP Bills in Chatsworth? Here’s How Solar Economics Work in 2026.
High electricity rates from the Los Angeles Department of Water and Power (LADWP) make solar an attractive option for reducing monthly expenses. However, the rules for getting credit for surplus solar energy have changed. In 2026, the power you send back to the grid is valued at a much lower rate than the power you buy. This shift makes using your own solar power directly—a concept called self-consumption—the most effective way to save money. For many homeowners, this means pairing solar panels with a home battery is now the smartest financial strategy.

Solar & Battery System Costs in Chatsworth
The total cost of a solar installation depends on system size and whether you include a battery. Below are modeled estimates for a typical Chatsworth home, with no federal tax credits assumed for systems installed in 2026.
- A 6.8 kW solar-only system is estimated to cost around $17,340.
- Adding a 10 kWh battery to that system brings the total estimated cost to $32,340.
These figures are benchmarks; the final price depends on your specific roof, equipment choices, and installation details. An owned solar system can also be a useful long-term home-value feature, potentially improving resale appeal.
Incentives & Tax Credits
California Solar Incentives in 2026
With the federal residential solar tax credit no longer available for systems placed in service in 2026, state-level benefits are more important than ever. For Chatsworth homeowners, the key incentive is California's property tax exclusion.
- Property Tax Exclusion: Installing a solar system will not increase your property taxes. The value added to your home by the solar installation is excluded from your property's assessed value, a benefit that runs through at least mid-2026.
- No State Tax Credit: California does not offer a state-level income tax credit for solar.
The primary financial benefit comes directly from reducing your high LADWP electric bills month after month.

Understanding LADWP's Export Compensation
LADWP operates independently from utilities like SCE and PG&E, but the principle is similar: the electricity you export to the grid is worth less than the electricity you import. Our model uses an estimated export rate of $0.11 per kWh, which is significantly lower than the retail rate of over $0.32 per kWh you pay to buy power. This difference is why maximizing self-consumption is critical. A battery allows you to store your solar energy, which is effectively worth $0.32/kWh to you, instead of selling it for just $0.11/kWh.
Projected Savings
How a Battery Maximizes Your Savings
With lower export rates, a solar-only system saves money by offsetting the power you use during the day. But a battery takes it a step further by storing that excess daytime energy for you to use in the evening, preventing you from having to buy expensive power from LADWP after the sun goes down.
- The solar-only system is modeled to save about $2,216 annually, with an estimated payback period of 7.2 years.
- The solar and battery system significantly increases savings to $3,308 annually. While the initial investment is higher, the payback period is only slightly longer at 8.1 years, and it delivers greater long-term financial benefits and energy independence.
If grid electricity becomes more expensive over time, rooftop generation can offset costlier power in future years, making your investment even more valuable.
