Every Solar Rebate Available to Temecula Homeowners in 2025: Federal, State, and SCE Programs

Adrian Marin|Independent Solar Advisor, Temecula CA

Helping Riverside County homeowners navigate SCE rates and solar options since 2020

A $30,000 solar installation in Temecula did not cost $30,000 after incentives through 2025 - and even without the federal purchase credit, which expired December 31, 2025, California's SGIP battery rebate, the active property tax exclusion, and energy efficiency credits for upgrades done alongside solar still bring most Temecula homeowners' net cost down meaningfully in 2026. The challenge is that these programs have different eligibility rules, different timelines, and specific stacking restrictions that are not well explained anywhere in one place. This guide covers every incentive available to Riverside County homeowners in 2025 and 2026, with specific dollar amounts, eligibility requirements, and practical notes for the Temecula market.

Quick Reference: All Available Incentives at a Glance

Federal Investment Tax Credit: What Happened to the 30 Percent Rate

Through December 31, 2025, the federal ITC under Section 25D was the largest single incentive available to Temecula solar buyers who purchased their system. It reduced federal income tax liability dollar-for-dollar by 30 percent of the total eligible cost - on a $30,000 system, that was $9,000 off the tax bill. The One Big Beautiful Bill Act, signed July 4, 2025, ended that credit for expenditures after December 31, 2025. A homeowner buying a system in 2026, cash or loan, gets no federal tax credit.

For a system that was placed in service on or before December 31, 2025, the credit applied on the return for that tax year, and any unused portion (if tax liability was lower than the credit) still carries forward - that part is unaffected by the repeal. If you want the value the credit used to represent for a 2026 purchase, a lease or PPA still carries it through Section 48E, the commercial version of the credit, as long as the system is placed in service by December 31, 2027.

What Counted Toward the ITC Basis (Through 12/31/2025)

For a qualifying system, the ITC applied to the total cost of the system as placed in service. Eligible costs included:

• Solar panels and all associated hardware (racking, mounting, clamps)
• Inverters (string inverter, microinverters, power optimizers)
• Battery storage systems -- but only batteries that were charged at least 75 percent from the solar system. A standalone battery with no solar connection did not qualify.
• Electrical wiring, conduit, disconnects, and the main panel upgrade if required to safely interconnect the system
• Labor costs for installation, including permit fees paid by the homeowner
• Monitoring equipment included in the installation contract
• Sales tax on equipment

None of this applies to a 2026 purchase, since there is no credit left to calculate a basis for. This section is kept for homeowners who purchased and placed a system in service on or before December 31, 2025 and are still working through their tax filing.

California SGIP: Battery Storage Rebates Up to $1.00 Per Watt-Hour

The Self-Generation Incentive Program (SGIP) is California's primary rebate for battery storage systems. It is administered by the California Public Utilities Commission (CPUC) and funded through a surcharge on utility customer bills. For Temecula homeowners, SGIP is administered through SCE and applied for through your solar installer at the time of installation.

SGIP comes in three tiers. Your tier depends on your income level and whether your address falls within a High Fire Threat District (HFTD). Here is how each tier works:

SGIP is subject to budget availability. When a step's budget is exhausted, applications are placed on a waitlist. Equity and Equity Resiliency tiers have dedicated budget allocation that is separate from Standard, so income-qualified customers typically face shorter wait times. Your installer submits the SGIP reservation at the time of contract signing, and the rebate is paid out after installation is complete and verified by SCE. SGIP rebates are considered taxable income by the IRS, so consult a tax professional about how to handle the rebate on your federal return.

California Property Tax Exclusion for Solar Installations

California Revenue and Taxation Code Section 73 provides that the assessed value of your home does not increase when you install an active solar energy system. This means your Riverside County property tax bill stays the same even though your home just became more valuable. The exclusion applies to:

• Solar panels (photovoltaic modules)
• Inverters and associated electrical equipment
• Battery storage systems installed as part of a solar project
• Solar water heating systems
• Monitoring and control equipment integral to the solar system

The exclusion does NOT apply automatically -- it requires a specific filing with the Riverside County Assessor's Office. Most solar installers in Temecula handle this filing as part of the installation process, but confirm this with your installer before signing the contract. The form is the BOE-64-SES (Solar Energy Systems -- Exclusion from Assessment).

As of 2025, the exclusion is active. The original legislation had a sunset date that has been extended multiple times. The current extension runs through at least 2026, and the California Solar and Storage Association has historically succeeded in extending it further. However, the exclusion is not permanent law, so homeowners considering solar should be aware that the landscape could change after 2025 if the Legislature does not act.

Federal 25C Energy Efficiency Credits: Ended December 31, 2025

The Inflation Reduction Act had expanded the Section 25C nonbusiness energy property credit into a much more valuable program, covering 30 percent of the cost of qualifying energy efficiency upgrades with annual caps by category. The One Big Beautiful Bill Act ended that credit: it is not allowed for any property placed in service after December 31, 2025. A 2026 efficiency upgrade gets no 25C credit.

The 25C credit used to matter to solar buyers because many Temecula homeowners improve their home's envelope or HVAC at the same time as solar installation. Those upgrades no longer carry an independent federal credit any more than the solar side does (which also no longer applies to a 2026 purchase). Here are the limits that applied through the end of 2025, for reference:

While it was active, the 25C credit was separate from the solar ITC and claimed on the same Form 5695 used for the solar credit. That no longer matters for planning purposes: a Temecula homeowner replacing their HVAC with a heat pump in 2026 gets no 25C credit for that upgrade, just as a 2026 solar purchase gets no ITC.

In Temecula, the most common upgrades that used to pair a 25C credit with solar were heat pump HVAC replacement (replacing a gas furnace and electric AC with a single efficient electric system that solar can power) and attic insulation to reduce cooling loads. A heat pump system typically costs $8,000 to $15,000 installed; without the 25C credit, that full range is out of pocket in 2026. Temecula's cooling-dominated climate still makes envelope upgrades -- particularly attic insulation and windows on west-facing walls -- cost-effective on their own utility-savings merits, because they reduce the peak cooling load that drives summer SCE bills.

SCE CARE and FERA Programs: How They Interact With Solar Bills

SCE's CARE (California Alternate Rates for Energy) and FERA (Family Electric Rate Assistance) programs reduce electricity rates for income-qualified customers. CARE provides a 30 to 35 percent discount on baseline electricity rates. FERA provides an 18 percent discount for households that do not qualify for CARE but meet a slightly higher income threshold. Both programs are applied as a discount on your SCE bill each month.

How CARE and FERA interact with solar is nuanced. If you are a CARE customer who installs solar, you continue to receive the CARE discount on any electricity you still purchase from SCE. Under NEM 3.0, your net metering exports are credited at the same avoided-cost export rate as non-CARE customers -- the CARE discount does not enhance your export credits. But your ongoing SCE charges for any grid electricity you consume are billed at the discounted CARE rate.

The more significant interaction is the SGIP eligibility unlock. CARE or FERA enrollment is one of the qualifying pathways for Equity SGIP ($0.85/Wh), which provides more than four times the battery rebate of Standard SGIP. If you are a CARE or FERA customer in Temecula who is considering battery storage, this is the most important number in this entire guide. A 10 kWh battery generates $8,500 in Equity SGIP versus $2,000 in Standard SGIP -- a $6,500 difference.

Stacking Incentives: What You Can and Cannot Combine

Stacking multiple incentives is legal and common. Through December 31, 2025, one specific rule governed how the ITC and SGIP interacted in the same tax year; for a 2026 purchase, there is no ITC left to stack, so SGIP simply applies on its own.

For a battery placed in service on or before December 31, 2025, a SGIP rebate received in the same tax year reduced the ITC basis before the 30 percent credit was calculated. Here is how that math worked in practice:

For CARE-eligible customers using Equity SGIP through 2025, the stacking math was more dramatic: a $12,000 battery minus an $8,500 Equity SGIP rebate left a $3,500 ITC basis, generating a $1,050 credit, for a total net cost of $2,450. For the same battery bought in 2026, Equity SGIP alone brings net cost to $3,500 - still a large discount, just without the additional $1,050 the ITC used to add.

The 25C credit (on separate efficiency upgrades like heat pumps or insulation) is gone too, for the same reason as the battery ITC discussed above: it is not allowed for any property placed in service after December 31, 2025. A 2026 heat pump or insulation upgrade gets no 25C credit regardless of whether solar is part of the same project.

HERO/PACE Financing: Why Most Temecula Solar Companies No Longer Recommend It

PACE (Property Assessed Clean Energy) financing -- sold under brand names like HERO, Ygrene, and Renovate America -- allows homeowners to finance solar and home improvements without a traditional credit check. Repayment is added to your annual property tax bill. PACE was once heavily promoted in the Inland Empire, and Riverside County was one of the largest PACE markets in California.

The product has significant structural problems that most Temecula solar companies now explain before recommending it:

• Lien seniority: PACE liens in California are senior to your mortgage. If you default, the PACE lender has priority over your mortgage lender in a foreclosure. Because of this, Fannie Mae and Freddie Mac backed loans (the majority of conventional mortgages) cannot be refinanced with an active PACE lien without the lender's explicit consent, which is rarely given.
• Home sale complications: When you sell your home with an active PACE lien, the buyer may not be able to assume the PACE obligation. In many Temecula transactions, this has required sellers to pay off the full PACE balance at closing, often eliminating any equity gain from the solar installation.
• Effective interest rate: PACE programs typically charge 7 to 10 percent annually, which is higher than conventional solar loan rates of 4.5 to 7 percent for most qualified buyers in 2025.
• Regulatory scrutiny: California has enacted consumer protection rules requiring disclosure of all PACE terms, but complaints about deceptive PACE sales practices in Southern California communities remain common at the CPUC and CFPB.

For Temecula homeowners who cannot qualify for a conventional solar loan due to credit or income constraints, PACE remains a legal financing option. But go in with full information. Compare the all-in cost (total interest paid over the term) to the alternative of a lease or PPA before signing. If you own your home and plan to sell in the next five to seven years, the PACE lien complication at closing is a material risk.

Temecula and the High Fire Threat District: What HFTD Status Means for SGIP

California's Office of Energy Infrastructure Safety designates High Fire Threat Districts across the state based on fire hazard severity. SCE uses this map to administer the Equity Resiliency tier of SGIP. In Temecula, not all neighborhoods are in an HFTD -- the designation is address-specific.

The areas most commonly in SCE's HFTD Zone D within Temecula include:

• The De Luz Road corridor and surrounding hillside properties west of I-15
• Unincorporated Riverside County parcels along Rainbow Canyon Road
• Scattered hillside parcels in the Old Town Temecula area near the Santa Margarita River corridor
• Wine Country road properties on dirt or narrow paved roads with limited emergency vehicle access

The main subdivisions of Temecula -- Redhawk, Wolf Creek, Crowne Hill, Meadowview, Morgan Hill, and most of the planned communities along Margarita Road and Butterfield Stage Road -- are generally NOT in an HFTD. If you live in a master-planned subdivision within Temecula city limits, verify your address specifically before assuming HFTD status.

To check your specific address: go to the SCE HFTD mapping tool at sce.com/safety/wildfire/hftd or use the California Energy Commission's address lookup. Your solar installer can also verify your HFTD status as part of the SGIP application process. An address that qualifies for Equity Resiliency SGIP can change the economics of battery storage dramatically -- confirm it early in the project, before you negotiate your installation contract.

Full Incentive Stack: What a Temecula Solar-Plus-Battery Installation Actually Costs

The following examples show how incentives combined for two typical Temecula homeowner profiles who purchased and placed their system in service in 2025, while the federal ITC was still available. For a 2026 purchase, drop the "Federal ITC" line entirely - Section 25D expired December 31, 2025 - and the net out-of-pocket is whatever remains after SGIP alone: $37,300 for Profile A and $26,500 for Profile B (the same figures already labeled "after SGIP reduction" below).

Frequently Asked Questions About Solar Rebates in Temecula

Getting the Numbers Right Before You Sign Anything

The most common mistake Temecula homeowners make with solar incentives is taking the installer's "net cost after incentives" number at face value without understanding what assumptions are behind it. Installers may quote the Standard SGIP rate when you actually qualify for Equity. They may not verify your HFTD status at the parcel level. And in 2026, some installers are still quoting numbers that assume the federal ITC, which no longer applies to a purchase.

Before signing any solar contract, ask these three questions specifically: What SGIP tier are you assuming, and have you verified my address on the HFTD map? Does your net cost number include a federal tax credit, and if so, is that for a purchase, a lease, or a PPA? Will you handle the BOE-64-SES property tax exclusion filing as part of the installation? The answers tell you quickly whether the installer knows this market or is giving you a generic Southern California pitch.
