Homeowners in the Westpark neighborhood of Irvine face some of the highest electricity costs in the nation from Southern California Edison (SCE). Switching to solar is a proven way to reduce that monthly burden. The key in 2026 isn't just generating power, but storing it to avoid SCE's costly peak rates under the state's new Net Billing tariff.
Benchmark Cost Analysis
2026 Solar + Battery System Costs in Westpark
A residential solar system paired with a home battery typically costs about $23,500 to install in Westpark. However, the 30% federal tax credit immediately brings your net investment down to approximately $16,450. This investment buys you freedom from SCE's time-of-use rate schedule and provides a reliable source of backup power.
It is vital to contrast this with solar-only quotes. While a system without a battery may seem cheaper upfront at ~$8,050 net, its savings are severely limited by NEM 3.0, making the combined system the superior financial choice for most Westpark residents.
Incentives & Tax Credits
Tax Credits & Local Perks
The main driver of affordability is the 30% Federal Residential Clean Energy Credit. This non-refundable credit is available through 2032 and can be applied to both solar panels and battery storage costs. In addition, California's property tax exemption ensures that the added value of your solar system won't increase your property tax bill, a significant benefit in Orange County.

Critical 🔋
Understanding SCE's Net Billing Tariff (NEM 3.0)
Since 2023, California's NEM 3.0 policy has reshaped the solar landscape. SCE now credits homeowners at a low 'avoided cost' rate (around 5-8¢/kWh) for exported electricity while charging full retail rates (27¢+ and much more during peak) to pull power from the grid. This makes a battery indispensable. Your system prioritizes storing your solar energy for your own use during high-cost evening hours, shielding you from this unfavorable rate structure.
Projected Savings
Your Expected ROI with Solar in Irvine
Based on a typical $243 monthly SCE bill, a Westpark family can save an average of $1,717 per year by installing a solar and battery system. This translates into a payback period of roughly 9.6 years. After that milestone, the solar energy you produce and consume is effectively free, protecting you from SCE's inevitable future rate increases.
