For homeowners in the planned community of Tustin Legacy, investing in solar energy is a forward-thinking move that matches the area's modern design. With average Southern California Edison (SCE) bills climbing, taking control of your energy costs with a home solar and battery system provides financial predictability and protection from future rate hikes. Here’s a breakdown of what to expect for costs and savings in early 2026.

Benchmark Cost Analysis

2026 Solar & Battery System Costs in Tustin Legacy

The key to maximizing your solar investment under current SCE rules is pairing panels with a battery. While a basic solar-only setup costs around $8,050 after incentives, its savings are severely limited by low export rates.

Therefore, the realistic and recommended path is a solar and battery system. The average gross price for a system sized for a home in Tustin Legacy is $23,500. After factoring in the federal tax credit, your final investment comes down to approximately $16,450. This setup has a typical payback period of 9.6 years and shields you from SCE's expensive peak electricity rates.

Incentives & Tax Credits

Primary Incentive: The 30% Federal Tax Credit

The most significant incentive available is the Residential Clean Energy Credit. This federal program allows you to claim 30% of your total system cost—panels, inverters, and battery included—as a dollar-for-dollar credit on your federal income taxes. For a $23,500 system, this credit is worth $7,050. California also offers a property tax exclusion, ensuring your property taxes don't go up when you add solar.

Why a Battery is Essential with SCE's Net Billing (NEM 3.0)

Since 2023, SCE's Net Billing Tariff (NEM 3.0) has been in effect. This policy means you are credited far less for the extra solar power you send to the grid compared to the retail rate you pay. With export rates often below 8¢/kWh and import rates climbing past 30¢/kWh, storing your own energy in a battery for nighttime use isn't just a bonus—it's the only way to make solar financially effective in Southern California.

Projected Savings

Projected Monthly and Annual Savings

A $243 average monthly bill from SCE can be drastically reduced with a home battery system. By generating your own power during the day and using stored energy at night, you can avoid buying high-cost electricity from the grid. Homeowners in Tustin Legacy can expect to save around $1,717 per year, which adds up to over $42,000 in savings over the 25-year life of the system.

Local Questions Answered
