High electricity bills from Southern California Edison (SCE) are a constant pressure for homeowners in West Puente Valley. In 2026, going solar is about more than just generating power; it's about using that power smartly. Under current rules, sending excess solar energy back to the grid doesn't pay what it used to. This shifts the focus to self-consumption — using the energy you produce to maximize your savings and reduce your reliance on an increasingly expensive grid.

2026 Solar & Battery Costs in West Puente Valley
The following are modeled costs for a typical home in the area, before considering any local rebates. Since the primary federal tax credit for homeowners expired at the end of 2025, these figures represent the full upfront investment.
- Solar-Only System (7.1 kW): A system of this size is estimated to cost around $18,105.
- Solar + Battery System (7.1 kW panels with a 10 kWh battery): This combined system has an estimated cost of $33,105. The battery adds backup power capability and significantly increases your ability to use your own solar energy after sunset.
Incentives & Tax Credits
California Solar Incentives for 2026
While the 30% federal tax credit is no longer available for systems installed in 2026, California homeowners still have a key financial benefit:
- Property Tax Exclusion: Installing a solar system in California will not increase your property taxes. This exclusion for active solar energy systems is a significant benefit that saves you money for the life of the system. According to current state law, this benefit applies to systems installed through June 30, 2026.
Beyond tax rules, an owned solar system can be a powerful asset for your home. It can enhance resale appeal, as potential buyers may see value in the lower, more predictable electricity bills that a solar and battery system provides.
Net Metering: Southern California Edison Co
Net Billing (low export)

Understanding SCE's Net Billing Tariff
West Puente Valley falls under Southern California Edison's territory, which uses a Net Billing Tariff (NBT). This system fundamentally changes solar economics compared to older net metering programs.
Here's the simple breakdown: you buy electricity from SCE at the full retail price (around $0.32/kWh), but when your panels produce more energy than you're using, the excess power you export to the grid is credited at a much lower rate (modeled here at about $0.11/kWh). This difference is why storing your excess solar power in a battery for later use is often more financially advantageous than selling it to the utility for pennies on the dollar.
Projected Savings
How a Battery Maximizes Your Solar Savings
With SCE's high retail rate of around $0.32 per kWh and a much lower export credit (modeled at $0.11 per kWh), storing your solar energy is more valuable than selling it. A battery lets you save your cheap, self-generated power from the afternoon and use it during the evening when grid electricity is most expensive.
- The solar-only system is modeled to save approximately $2,216 annually, with a payback period of about 7.5 years.
- Adding a battery boosts those savings significantly. The solar-plus-battery system is modeled to save $3,308 annually, with a payback period of around 8.3 years. While the initial cost is higher, the battery increases your energy independence and long-term bill reduction.
These savings also act as a hedge against future utility rate hikes. If grid electricity becomes more expensive over time, the value of your rooftop-generated power increases right along with it.
