For homeowners in Montebello, rising electricity bills from Southern California Edison (SCE) aren't a surprise. What is surprising is how drastically the rules for solar have changed. Under the state's NEM 3.0 policy, sending your excess solar power to the grid no longer earns you the high credits it used to. This makes a battery storage system not just an add-on, but an essential part of any modern solar installation in Los Angeles County.
Benchmark Cost Analysis
How Much Does a Solar + Battery System Cost in Montebello?
Expect a typical solar and battery system in Montebello to have a gross cost of around $23,500 before incentives. While a basic solar-only system can be installed for as little as $11,500, it offers minimal savings under current SCE rules. To gain true energy independence and maximize your return, investing in battery storage is the recommended path.
After claiming the 30% Federal Solar Tax Credit, the net cost of a solar-plus-battery system drops to approximately $16,450. This investment is designed to protect you from SCE's expensive peak electricity rates, which can be 2-3 times higher in the late afternoon and evening.
Incentives & Tax Credits
Montebello Solar Incentives (2026)
- Federal Solar Tax Credit: This is the most significant incentive. You receive a credit worth 30% of your total system cost (panels and battery) when you file your federal taxes. For a $23,500 system, that's a $7,050 credit.
- Property Tax Exemption: Installing solar panels increases your home's value, but thanks to California's Property Tax Exclusion for Solar Energy Systems, your property taxes will not increase.
- No State Rebate: California's state-level solar rebates have largely been phased out in favor of the NEM structure. The savings come from bill reduction, not an upfront rebate from the state.

NEM 3.0 (2023)
Critical 🔋
Understanding SCE's Net Billing (NEM 3.0)
The Net Billing Tariff, or NEM 3.0, is SCE's current policy for solar customers. The old net metering system gave you nearly a 1-for-1 credit for power you sent back to the grid. Under NEM 3.0, the value of that exported energy has been cut by about 75%. The credit you get is so low that it makes financial sense to store every possible kilowatt-hour in your own battery and use it yourself later. Without a battery, your solar investment simply won't perform as expected.
Projected Savings
Projected Electric Bill Savings
With an average electric bill of $243, a Montebello home with a solar and battery system can expect to save around $1,531 annually. Instead of selling your excess energy back to SCE for pennies, your battery stores that power. When evening peak rates kick in, you use your own stored, free solar energy instead of buying expensive grid power. This self-consumption strategy is what delivers significant savings under NEM 3.0, leading to a system payback period of about 10-11 years.
