For homeowners in Tustin Legacy, high electricity bills from Southern California Edison (SCE) are a constant pressure. With retail rates around $0.323 per kWh, finding ways to reduce that cost is a priority. Rooftop solar is a powerful tool, but the financial equation has changed. Under California's net billing system, using the energy you generate yourself is far more valuable than exporting it to the grid. This makes pairing solar panels with a home battery a strategic choice for maximizing savings and energy independence in 2026.

Solar Panel System Costs in Tustin Legacy (2026)
Here are modeled cost estimates for a typical home in the Tustin Legacy area. These figures represent the full gross cost before any savings are applied, as the 30% federal tax credit for homeowners is no longer the default incentive for systems installed in 2026.
- Solar-Only System (7.1 kW): A system of this size, designed to offset a significant portion of a typical local electricity bill, has an estimated gross cost of $18,105.
- Solar + Battery System (7.1 kW panels with a 10 kWh battery): Adding energy storage to the system increases the upfront cost to approximately $33,105. The battery allows you to store solar energy generated during the day for use at night, which is critical for savings under SCE's current rules.
These costs are estimates. The final price depends on your specific roof, equipment choices, and installation partner.
Incentives & Tax Credits
California Solar Incentives for 2026
While the landscape of solar incentives has shifted, California homeowners still have valuable benefits available. The primary financial driver is avoiding SCE's high retail electricity rates, but state-level policies provide additional support.
- Property Tax Exclusion: Installing a solar system in California will not increase your property taxes. The added value of the solar installation is excluded from your home's valuation for tax purposes, a significant benefit that saves you money every year.
- No State Income Tax Credit: California does not offer a state-level tax credit for solar installations.
- Focus on Self-Consumption: The most significant financial incentive is now the savings you achieve by using your own solar power. Every kilowatt-hour you generate and use at home is a kilowatt-hour you don't have to buy from SCE at their high rates.

Net Billing (low export)

Understanding Export Compensation with SCE
Under the current net billing tariff (often called NEM 3.0), Southern California Edison compensates you for surplus energy sent to the grid at a rate much lower than what you pay for electricity. Our model uses an estimated export value of around $0.113 per kWh, while you pay SCE roughly $0.323 per kWh to buy that same energy back.
This difference is why battery storage is now highly recommended. A battery lets you store your excess solar power instead of exporting it for a low credit. You can then use that stored energy during the evening, avoiding high-priced grid power and maximizing the value of every kilowatt-hour your panels produce.
Projected Savings
Expected Electricity Bill Savings
Installing solar panels is about long-term financial benefits, especially as utility rates climb. A solar system protects you from future price hikes by locking in your energy costs. With California's high electricity prices, the savings from self-consuming your own solar power are substantial.
- With a solar-only system, you could see an estimated annual savings of $2,216, leading to a payback period of around 7.5 years.
- Adding a battery storage system significantly increases your ability to use your own power, boosting estimated annual savings to $3,308. While the initial cost is higher, the payback period is only slightly longer at 8.3 years, and the long-term savings are greater.
An owned solar system can also be an attractive feature for potential buyers, potentially supporting your home's resale appeal down the road.
