High electricity rates from Southern California Edison are a major concern for Fountain Valley homeowners. While solar panels are a powerful way to generate your own clean energy, the rules have changed. In 2026, sending surplus solar power back to the grid doesn't earn you what it used to. This makes maximizing your own solar usage—a practice called self-consumption—the most effective strategy for saving money. This is where pairing solar panels with a home battery becomes a practical and financially savvy choice.

2026 Solar & Battery Costs in Fountain Valley
Here are the modeled costs for a typical system sized for an average Fountain Valley home, before any incentives. Note that the federal tax credit for solar is no longer available for systems installed in 2026.
- Solar-Only System (7.2 kW): The estimated gross cost is around $18,360.
- Solar + Battery System (7.2 kW panels, 10 kWh battery): The estimated gross cost for a combined system is approximately $33,360.
These figures are based on a cost of $2.55 per watt for solar and include the addition of a 10 kWh battery. An owned solar system can also be an attractive feature for future homebuyers, potentially supporting your property's long-term value.
Incentives & Tax Credits
California's Solar Incentives in 2026
While the 30% federal investment tax credit (ITC) is no longer available for residential solar systems placed in service in 2026, California homeowners still benefit from a key state-level incentive:
- Property Tax Exclusion: In California, installing a solar panel system does not increase your property taxes. The added value of the solar installation is excluded from your home's valuation for tax purposes, a benefit that runs through at least mid-2026.
The primary financial benefit of going solar now comes from bill avoidance—using your own power to sidestep SCE's high and rising electricity rates—rather than from tax credits.

Net Billing (low export)

Understanding Export Rates with Southern California Edison (SCE)
Under the current Net Billing Tariff (NBT), the value of solar energy you send back to the grid is much lower than the retail price you pay for electricity. You might pay SCE over $0.32 per kilowatt-hour (kWh) for power, but the credit you receive for exporting is modeled here at around $0.11 per kWh. This difference is why storing your solar energy in a battery for later use is so valuable. By using your own stored energy, you avoid buying expensive power from the grid, which delivers far greater savings than exporting it for a small credit.
Projected Savings
How a Battery Increases Your Solar Savings
With SCE's current net billing structure, the electricity you export is valued at a fraction of the high retail rate you pay. A battery solves this by storing your excess solar energy for use in the evening, when the sun isn't shining but utility rates are high. This dramatically reduces the amount of expensive power you need to buy from the grid.
- A solar-only system is modeled to save a Fountain Valley homeowner about $2,216 annually, with a payback period of around 7.6 years.
- Adding a battery boosts those savings significantly to $3,308 annually. While the initial investment is higher, the payback period is only slightly longer at 8.3 years, and you gain the crucial benefit of backup power during outages.
If grid electricity becomes more expensive over time, rooftop generation stored in your battery can offset even costlier power in future years, improving the system's long-term value.
