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

Updated May 18, 2026  |  Temecula & Riverside County

A 7.5-kilowatt solar system installed on a Temecula home in 2026 runs between $18,000 and $26,000 before the 30% federal tax credit. For most homeowners, that is not a check you write from savings. You are financing it. How you finance that system determines whether solar works financially or quietly becomes a drag on your household budget for two decades.

There are five distinct paths: cash purchase, solar loan, solar lease, Power Purchase Agreement (PPA), and PACE financing through your property tax bill. Each has a different owner, a different tax credit outcome, different monthly payment math, and a different consequence when you try to sell your home. This guide covers all five in detail, including the specific California programs that affect your decision in 2026: the federal ITC, SGIP battery rebates, and the shift from NEM 2.0 to NEM 3.0 in SCE territory.

The Five Solar Financing Paths: What Separates Them

The single most important question in solar financing is: who owns the system? System ownership determines who gets the 30% federal tax credit, who is responsible for maintenance, and how the deal plays out when you sell your home.

With a cash purchase or solar loan, you own the system from day one. With a PPA or lease, a separate company owns the panels on your roof and you are paying that company for either the electricity produced or the right to use the equipment. PACE is ownership-based but uses a property tax lien instead of a traditional loan.

Cash Purchase: Highest Return, Requires Capital

A cash purchase means you pay the full installed cost of the system out of pocket or through a home equity loan or HELOC that you arrange independently. You own every component from day one with no third-party contracts, no dealer, no escalator clause.

For a 7.5-kW system in Temecula in 2026, the gross installed cost typically runs $21,000 to $25,000 depending on panel brand, inverter type, and installer. The 30% federal ITC reduces that by $6,300 to $7,500, bringing your net cost to roughly $14,700 to $17,500. With annual electricity savings of $1,800 to $2,400 at current SCE rates, simple payback runs 6 to 9 years. After payback, the system produces electricity at essentially zero ongoing cost for another 16 to 20 years.

Cash purchase is also the cleanest path for home resale. An owned system appraised under the energy improvements category typically adds $10,000 to $25,000 to a Riverside County home value according to Lawrence Berkeley National Laboratory research. A buyer does not have to assume any lease or satisfy any lien. The system transfers with the title, period.

The limitation is obvious: most homeowners do not have $20,000 sitting in savings earmarked for solar. A HELOC or home equity loan at 7% to 9% can bridge this, but at that rate a purpose-built solar loan often wins on total cost. Cash purchase is best when you have liquid savings, a strong reserve after purchase, and enough federal tax liability to capture the full ITC in year one.

Solar Loans: The Most Common Choice in Temecula

A solar loan lets you own the system with zero or low money down while spreading the cost over 10 to 25 years. You keep the 30% federal ITC. Your monthly loan payment replaces your SCE bill, and in most cases in Temecula, the loan payment is lower than what you were paying SCE from day one.

The major solar loan lenders operating in California in 2026 include GoodLeap (formerly LoanPal), Dividend Finance, Mosaic, and GreenSky. Rates from these lenders for borrowers with 700+ FICO scores run approximately 5.99% to 8.99% on 10 to 15-year terms, and 7.99% to 12.99% on 20 to 25-year terms. Borrowers in the 650 to 699 range typically see rates 2 to 4 points higher.

Term length has a large effect on monthly payment versus total interest paid. On a $20,000 solar loan: a 10-year term at 6.99% produces a $232 monthly payment and $7,840 in total interest; a 15-year term at 7.99% produces $191 per month and $14,380 in total interest; a 20-year term at 8.99% produces $180 per month and $23,200 in total interest; and a 25-year term at 9.99% produces $182 per month and $34,600 in total interest. The 25-year loan carries more than four times the interest of the 10-year loan. Most homeowners focus on the monthly payment without doing this math. If you can afford the 10 or 15-year payment, the lifetime cost difference is substantial.

Solar loans come in two main structures. Secured loans are backed by a lien on your home, similar to a HELOC, and carry lower rates because the lender has collateral. Unsecured solar loans are personal loans with no lien on your title, closing faster but at higher rates (typically 1 to 3 points above comparable secured products). Most residential solar loans from the lenders listed above are unsecured personal loans.

One critical feature to read carefully in any solar loan is the ITC recapture provision. Many loans are structured so that the monthly payment assumes you will apply your ITC refund to the principal within 18 months of system activation. If you do not, the monthly payment may step up or a balloon payment may trigger equal to the ITC amount. If you are not certain you will owe at least $6,000 in federal tax in the year you install, a loan with this provision is a risk worth understanding before you sign.

Dealer fees are the other major variable in solar loan cost. When an installer sells you a system through their preferred lending partner, the lender pays the installer a dealer fee of 20% to 30% of the loan amount. The installer covers that fee by marking up the system price. A system with an actual installed cost of $20,000 can appear as a $26,000 contract. Ask every installer for their cash price separate from financing and compare across bids. The gap reveals the dealer fee embedded in their loan product.

The Federal Investment Tax Credit: How It Works in 2026

The federal solar Investment Tax Credit (ITC) is the most valuable financial incentive available to California solar buyers. It is a dollar-for-dollar reduction in your federal income tax liability, not a deduction from taxable income. A $7,000 tax credit reduces your tax bill by $7,000. A $7,000 deduction reduces your bill by your marginal rate times $7,000, roughly $1,750 at a 25% rate. The difference is significant.

The current ITC schedule under the Inflation Reduction Act: systems placed in service through December 31, 2032 receive a 30% credit of the gross installed cost. Systems placed in service in 2033 receive 26%. Systems placed in service in 2034 receive 22%. The residential ITC phases out entirely after 2034.

On a $23,000 system installed in 2026, the ITC is $6,900. You claim it on IRS Form 5695 in the tax year the system is placed in service. If your total federal tax liability for that year is only $4,000, you receive $4,000 in credit and the remaining $2,900 carries forward to the next tax year. The credit is non-refundable, meaning it cannot reduce your tax liability below zero or result in a refund check if you had no liability at all.

With a solar loan, the ITC goes to you, the system owner. You can apply that credit to pay down the loan principal in year one, reducing your long-term interest costs. With a solar lease or PPA, the solar company owns the system and claims the ITC. You receive none of it. This is the primary financial disadvantage of lease and PPA structures for California homeowners who have meaningful federal tax liability.

Solar Leases: Zero Down, but the Economics Rarely Win

A solar lease is straightforward: a solar company installs panels on your roof at no upfront cost, and you pay a fixed monthly amount to use the electricity they generate. Terms run 20 to 25 years. The solar company owns the system, handles maintenance, and claims the federal ITC.

The monthly lease payment is typically set below your current electricity bill, creating an apparent immediate savings. That is the pitch. What the pitch often omits is the escalator clause.

Nearly all solar leases include an annual escalator of 1.5% to 3% per year. At 2.9% annually, a $120/month lease payment in year one becomes $195/month by year 20 and $225/month by year 25. Whether this beats your SCE bill at that point depends entirely on how fast SCE rates rise over the same period. SCE rates have historically increased 4% to 6% annually, which means a 2.9% escalator may still produce relative savings in year 20. But the gap narrows each year, and you are betting on a 25-year rate forecast locked into a contract you cannot easily exit.

More importantly, compare the 25-year total outlay of a lease against the 25-year total cost of ownership of a purchased system. In most Temecula scenarios, the owned system costs less in total money spent over 25 years even including interest on a loan, and the homeowner ends with an owned asset rather than an expired lease and nothing to show for two decades of payments.

Solar leases also complicate your home sale. You cannot simply sell the house with the lease attached without resolution. You must either transfer the lease to the buyer (who must qualify under the leasing company's credit requirements and agree to the remaining term) or buy out the lease at its current value, which can range from $5,000 to more than $20,000. Some buyers in Riverside County refuse homes with active solar leases entirely to avoid the assumption process. If you plan to sell within 5 to 10 years, a lease is especially difficult to recommend.

Power Purchase Agreements: Pay Per Kilowatt-Hour, No Ownership

A PPA functions similarly to a lease in terms of ownership and contract structure but with a different billing mechanism. Instead of a fixed monthly payment, you pay a per-kilowatt-hour rate for the electricity your panels produce, typically set at 10% to 30% below your current SCE rate at signing.

For a Temecula homeowner currently paying $0.40 per kWh average (a reasonable blended rate under SCE time-of-use billing in 2026), a PPA at $0.29 per kWh sounds like a meaningful discount. And it is in year one. The problem is the same escalator clause that affects leases: if your PPA rate escalates at 2.9% annually, you are paying $0.47 per kWh by year 20, which may be close to or above what SCE charges at that time.

PPAs also introduce production variability. If your system produces less than expected due to shade, soiling, or panel degradation, your PPA payment drops but your SCE bill for the shortfall rises. You bear the shortfall cost even though you do not own the system.

One genuine advantage of PPAs: the solar company owns and maintains the equipment. If an inverter fails in year 12, the PPA company handles it. Under a cash or loan purchase, you own the problem and pay for repairs beyond manufacturer warranty coverage. For homeowners who want to maximize current cash flow and minimize maintenance responsibility, a PPA with a low escalator (under 2%) from a financially stable provider can make sense. It is almost never the best long-term financial outcome, but it is not irrational for certain buyer profiles.

PPAs carry the same home sale complications as leases. You must either transfer the agreement to the buyer or buy out the remaining contract. PPA buyout prices are often set at a formula that captures the net present value of remaining payments at a discount rate that favors the company. Buyout prices of $15,000 to $25,000 for 15 remaining years of PPA are not unusual.

PACE and HERO Financing in California: Property Tax Bill Solar Loans

PACE stands for Property Assessed Clean Energy. It is a government-backed financing mechanism that allows Riverside County homeowners to finance solar by adding the loan repayment to their annual property tax bill. Major PACE lenders operating in California include Ygrene Energy Fund and CalFirst Finance. The HERO program was an early PACE product in Riverside County that is no longer accepting new applications but whose legacy loans still appear on Riverside County properties.

The defining feature of PACE is that it bypasses personal credit. Your FICO score is irrelevant. What matters is that you own the home, have equity, and can demonstrate ability to repay under California's 2022 PACE consumer protection reforms.

PACE financing attaches to the property as a special tax assessment. It is senior to your mortgage in payment priority, meaning in a foreclosure the PACE lien is paid before your mortgage lender. This is why most mortgage servicers require written notification when a PACE lien is added, and some loan agreements specifically prohibit PACE financing without servicer approval. More significantly, Fannie Mae, Freddie Mac, FHA, and VA have all issued guidance that they will not purchase, guarantee, or refinance mortgages on properties with outstanding senior PACE liens under current federal guidelines. If you have a PACE lien and want to refinance your conventional mortgage later, your lender will likely require you to pay off the PACE balance before closing.

Interest rates on PACE products in California typically run 6% to 9%. Terms range from 10 to 30 years. On a $20,000 PACE-financed solar installation at 7.5% for 20 years, you pay approximately $1,865 per year added to your property tax bill, and total repayment exceeds $37,000. Compare that to a $20,000 solar loan at 7.99% for 15 years totaling $34,380 with no property lien complication.

The California PACE Reform Act (AB 422), signed in September 2022, addressed prior consumer protection concerns by requiring income verification and documented ability-to-pay assessment before financing approval, clear written disclosure of total repayment amount, annual payment, interest rate, and term, a three-day right of rescission after signing, and a prohibition on financing that would result in annual PACE payments exceeding 5% of the homeowner's documented gross annual income.

PACE is best suited to a narrow set of homeowners: those with damaged or thin credit who own their home outright or have substantial equity, those certain they will not refinance or sell before the PACE balance is paid off, and those who understand the mortgage lien complications and have consulted their mortgage servicer before applying. For everyone else, PACE's lien priority creates risks that outweigh its qualification advantages. If your installer recommends PACE without explaining the FHA and VA mortgage implications, treat that as a signal to ask harder questions.

NEM 3.0 and What It Means for Solar Financing in SCE Territory

California's Net Energy Metering policy changed fundamentally on April 14, 2023, when the California Public Utilities Commission approved NEM 3.0, now branded as the Net Billing Tariff (NBT). Temecula and the surrounding Riverside County area falls within Southern California Edison (SCE) territory, so this policy directly affects every solar installation made after that date.

Under NEM 2.0, excess solar power exported to the grid during the day was credited at near-retail electricity rates, roughly $0.30 to $0.45 per kWh depending on the time of day and rate plan. Under NEM 3.0, daytime export credits average $0.05 to $0.08 per kWh, a reduction of 75% to 85%. You still export surplus power during the day, but the credit you receive is a fraction of what it used to be. Meanwhile, the electricity you draw from SCE during peak evening hours still costs $0.35 to $0.55 per kWh.

The practical effect on financing is significant. Solar-only systems without battery storage have longer payback periods than they did under NEM 2.0. Battery storage is now much more financially valuable: a battery allows you to store daytime surplus and use it during peak evening hours at a self-consumption value of $0.35 to $0.55 per kWh rather than exporting it for $0.05 to $0.08 per kWh.

Homeowners who interconnected under NEM 2.0 before April 14, 2023 are grandfathered for 20 years from their original interconnection date. If you have a NEM 2.0 system, it retains its original export credit rates. Do not let a contractor talk you into a system replacement that resets your NEM 2.0 grandfathering without fully understanding the financial consequence.

When evaluating solar loan offers, confirm that any savings projection your installer provides accounts for NEM 3.0 export rates, not the old NEM 2.0 rates. Projections built on NEM 2.0 assumptions overstate annual savings by 15% to 30% for systems that export significant daytime surplus. This is one of the most common sources of disappointment among Temecula homeowners who went solar in 2023 or 2024 with proposals written before the rate change.

SGIP Battery Rebates: California's Incentive That Stacks on Any Financing Structure

California's Self-Generation Incentive Program (SGIP) is a rebate program administered by the state's investor-owned utilities, including SCE, that pays homeowners for installing qualifying battery storage systems. It is independent of your financing structure and stacks on top of both the federal ITC and any solar loan or PACE product.

SGIP pays per kilowatt-hour of usable battery capacity. In the standard residential tier for SCE customers in 2026, the incentive rate is approximately $200 per kWh. For a 13.5 kWh Tesla Powerwall 3, that is $2,700. For two Enphase IQ Battery 5P units totaling 10 kWh, it is $2,000.

Equity-eligible households, including those in Tier 2 or 3 High Fire Threat Zones (which includes significant portions of Riverside County), low-income households, and those on medical baseline rates receive a substantially higher SGIP rate of up to $1,000 per kWh. For these households, a 13.5 kWh Powerwall 3 qualifies for $13,500 in SGIP rebate, which can exceed the net installed cost of the battery after the federal ITC. If you qualify for the equity tier, battery storage is essentially free or close to it.

SGIP funds are allocated in budget steps and are not always immediately available. The waitlist for standard-tier SCE applicants can run 6 to 18 months. Your installer applies on your behalf after installation. The rebate is paid to the installer and should be reflected in a reduced final invoice. Confirm this arrangement in writing before signing any contract that promises an SGIP rebate. From a financing standpoint, SGIP significantly improves the battery storage payback calculation: a $12,000 Powerwall 3 installation qualifying for a $3,600 federal ITC and $2,700 SGIP rebate has a net cost of approximately $5,700 before loan interest.

Red Flags in Solar Financing Contracts: What to Catch Before You Sign

California's solar market includes reputable installers and a persistent fringe of contractors who use financing complexity to obscure true costs. Here are the specific red flags to identify before signing any solar contract.

How to Compare Solar Financing Offers: Total Cost of Ownership

Monthly payment comparisons mislead almost every solar buyer. A $150 per month solar lease looks cheaper than a $210 per month loan payment until you account for 25 years of escalating lease costs and zero asset ownership versus a paid-off system in year 15. The correct comparison metric is total cost of ownership over 25 years, minus the value of electricity savings and the ITC.

The framework:

1. Get the cash price from every installer for a comparable system specification. This is your baseline system cost before any financing overhead.
2. Calculate your net cost after the 30% ITC if you own the system. For a $23,000 cash price, that is $16,100 net.
3. For loans: add total interest paid over the term to the net cost. Then subtract cumulative electricity savings over the loan term. The difference is your net financial position at loan payoff.
4. For leases and PPAs: sum every monthly payment over 25 years including escalator increases. Compare that total against what you would have paid SCE over the same period at an assumed 4% annual rate increase.
5. Add home sale impact: owned systems add appraised value and transfer cleanly. Leased systems can slow or complicate a sale. Quantify this based on how long you plan to own the home.

This analysis takes 30 to 45 minutes with a spreadsheet and almost always reveals that cash purchase and low-rate solar loans produce better 25-year outcomes than leases or PPAs for Temecula homeowners with federal tax liability. The exception is homeowners with zero or near-zero federal tax liability, for whom the ITC advantage of ownership disappears and the lease or PPA becomes more competitive on a pure cash flow basis.

Credit Score Strategy for Solar Loans in Riverside County

If your FICO score sits below 680, spending 6 to 12 months improving it before applying for a solar loan can save you several thousand dollars in total interest. A borrower at 680 FICO applying for a $22,000 solar loan through GoodLeap or Mosaic in 2026 might receive a rate of 9.99% for a 20-year term, paying about $23,800 in total interest. The same borrower at 720 FICO often qualifies for 7.49%, cutting total interest to about $16,700, a difference of over $7,000.

Key actions to raise your score before a solar loan application: pay down revolving credit balances to below 30% utilization on each card, dispute any collection accounts or inaccurate negative items with all three bureaus, avoid opening new credit accounts in the 90 days before applying, and request a credit limit increase on existing cards without a hard pull to lower utilization ratios.

If you cannot wait and need solar financing now at a lower credit score, PACE financing is available without a credit check. The rate will be higher (6% to 9%), but you own the system and qualify for the ITC, which is more valuable than a lease structure where the ITC goes to the leasing company. Some credit unions in Riverside County also offer personal loan products at competitive rates for members with mid-range credit. Check your credit union before assuming a solar lender's rate is your best available option.

Which Financing Option Fits Your Situation

There is no universal answer, but there is a logical decision tree based on your specific situation.

Next Steps: Getting Solar Financing Right Before You Talk to an Installer

The financing decision comes before the installer decision, not after. When you start getting solar quotes, you want to already know which financing structure you are targeting so you can evaluate installers against that framework instead of letting their preferred financing partner drive your decision.

Before you contact a single installer, take these steps:

1. Pull your credit score from all three bureaus. Know your FICO number before any lender does.
2. Calculate your estimated federal tax liability for this year. If you owe less than $3,000 in federal income tax annually, the ITC advantage of ownership is limited and you should factor that into your structure decision.
3. Determine your monthly payment comfort zone. This affects term selection for loans and whether a lease payment makes sense relative to your current SCE bill.
4. Check whether your home qualifies for the equity-tier SGIP rebate. High Fire Threat Zone status, low-income programs, and medical baseline rates all expand battery storage economics dramatically.
5. If considering PACE, review your mortgage terms to confirm they do not prohibit PACE financing, and contact your mortgage servicer in writing before applying.

With that groundwork done, get at least three quotes from licensed C-10 California electrical contractors. Ask each one for both a cash price and a financed price for the same system specification. The gap between those two numbers tells you the dealer fee embedded in their preferred loan product. Solar financing in California is genuinely more complicated than most installers present it to be. The homeowners who do best over 25 years are the ones who understood the total cost of ownership before they signed.
