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

A $30,000 solar installation in Temecula does not cost $30,000 after incentives. Between the federal Investment Tax Credit, California's SGIP battery rebate, the active property tax exclusion, and energy efficiency credits for upgrades done alongside solar, most Temecula homeowners bring their net cost down by 35 to 55 percent. 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: 30 Percent Through 2032

The federal ITC is the largest single incentive available to Temecula solar buyers. It reduces your federal income tax liability dollar-for-dollar by 30 percent of the total eligible cost of your solar installation. On a $30,000 system, that is $9,000 directly off your tax bill. On a $45,000 system with battery storage included, the credit is $13,500.

The credit applies in the tax year the system is placed in service, meaning the year the system passes inspection and is turned on. If your system is installed in November 2025 and passes inspection in November 2025, you claim the credit on your 2025 federal return filed in spring 2026. If your tax liability for the year is less than the credit amount, the unused portion carries forward to the following tax year -- it does not expire after one year.

What Counts Toward the ITC Basis

The ITC applies to the total cost of the system as placed in service. Eligible costs include:

• Solar panels and all associated hardware (racking, mounting, clamps)
• Inverters (string inverter, microinverters, power optimizers)
• Battery storage systems -- but only batteries that are charged at least 75 percent from the solar system. A standalone battery with no solar connection does 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

What does NOT count toward the ITC basis: roofing work done at the same time as solar installation (unless the roofing portion of the roof is structural support for the panels and serves no other purpose), landscaping, and tree removal to clear shading obstructions. If you are financing the system, you claim the ITC on the full system cost -- not just the down payment. The credit is based on total cost, regardless of how you pay.

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: Stack These Alongside Solar

The Inflation Reduction Act expanded the Section 25C nonbusiness energy property credit into a much more valuable program. The 25C credit now covers 30 percent of the cost of qualifying energy efficiency upgrades, with annual caps by category. This credit runs through 2032, the same window as the ITC, and can be claimed in any year you make qualifying upgrades -- it resets annually.

The 25C credit matters to solar buyers because many Temecula homeowners improve their home's envelope or HVAC at the same time as solar installation. Done in the right sequence, these upgrades are independently credit-eligible and are additive to the ITC. Here are the 2025 limits:

The 25C credit is separate from the ITC and is claimed on the same Form 5695 used for the solar credit. A Temecula homeowner who installs solar in year one and replaces their HVAC with a heat pump in year two can claim the ITC in year one and a separate 25C credit in year two. The credits do not compete with each other.

In Temecula, the most common 25C upgrades alongside solar are heat pump HVAC replacement (replaces 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, making the $2,000 credit meaningful. Temecula's cooling-dominated climate makes envelope upgrades -- particularly attic insulation and windows on west-facing walls -- especially cost-effective 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 -- but one specific rule governs how the ITC and SGIP interact in the same tax year.

When you receive a SGIP rebate in the same tax year that your battery is placed in service and you claim the ITC, the SGIP rebate reduces your ITC basis. Under IRS rules, when a subsidized energy financing benefit reduces your cost, your tax credit basis must be reduced accordingly. Here is how the math works in practice:

For CARE-eligible customers using Equity SGIP, the stacking math is more dramatic. A $12,000 battery minus an $8,500 Equity SGIP rebate leaves a $3,500 ITC basis, generating a $1,050 credit. Total net cost: $2,450 for a battery system that installed for $12,000. After combining Equity SGIP and the ITC, the battery is about 80 percent subsidized.

What you CAN stack without basis reduction issues: the ITC (on solar panels) and the 25C credit (on separate efficiency upgrades like heat pumps or insulation). These are different credits on different assets. You can claim both in the same year or in different years. The solar ITC does not reduce the 25C basis, and vice versa.

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.

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 account for the SGIP basis reduction on the ITC calculation. They may not verify your HFTD status at the parcel level.

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? How does the SGIP amount reduce my ITC basis in your net cost calculation? 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.
