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

The financing structure you choose matters as much as the panels on your roof. Loans let you own the system, claim the 30% federal tax credit, and build home equity. Leases and PPAs hand those advantages to the installer. Here is a plain-English breakdown of every option for Temecula and Murrieta homeowners in 2026.

Ownership: The Core Question Behind Every Financing Choice

Every solar financing decision flows from one question: who owns the panels? When you take a solar loan, you own the system from day one. The installer transfers title to you at commissioning, and the panels are treated like any other home improvement on your property.

When you sign a lease or a power purchase agreement (PPA), the solar company owns the equipment and installs it on your roof under a long-term contract, typically 20 to 25 years. You are either paying a fixed monthly lease payment for the right to use the system, or you are buying electricity the system produces at a contractually fixed rate that is usually below your current utility rate. The company that owns the panels receives the 30% federal Investment Tax Credit (ITC), not you.

In Temecula and Murrieta, an 8 kW system costs approximately $22,000 to $27,000 before incentives. The 30% ITC on that system is $6,600 to $8,100. When you own the system through a loan or cash purchase, that credit reduces your federal tax liability dollar for dollar. When you lease, the company keeps it.

Solar Loans: Types, APRs, and the Hidden Dealer Fee

Most residential solar loans in California today are unsecured personal loans originated by specialty lenders such as Mosaic, Goodleap, Sunlight Financial, and Dividend Finance. Rates in 2026 range from 5.99% to 9.99% APR for borrowers with credit scores above 700, with terms of 10, 15, 20, or 25 years. Monthly payments on a $22,000 loan at 7.99% for 20 years are approximately $183 per month.

Secured solar loans, including PACE (Property Assessed Clean Energy) loans offered in Riverside County through programs like Ygrene and HERO, are tied to your property rather than your credit score. PACE loans are repaid through your property tax bill as an assessment. They carry no credit check, but they can complicate refinancing and resale because the lien is senior to the mortgage. PACE rates in 2026 run from 5.5% to 8.9%, but total financing costs including origination fees can push the effective rate higher.

The most important number in a solar loan that almost no salesperson volunteers is the dealer fee. Solar lenders charge installers a fee of 15% to 30% of the loan amount for originating the loan through their platform. Installers routinely embed this fee in the system price. A system that would sell for $22,000 cash may be quoted at $26,000 or $28,000 when financed through the installer's preferred lender. Always ask for the cash price and the financed price side by side, and calculate the difference as a percentage. If it exceeds 12%, the dealer fee is inflating your total cost significantly.

Payment Comparison for a Typical 8 kW Temecula System

At a cash system price of $24,000 and the 30% ITC of $7,200, net cost is $16,800. Spread across 25 years of solar production, that is $56 per month in amortized cost. An 8 kW system in Temecula produces roughly 13,000 to 14,500 kWh per year, offsetting approximately $195 to $218 per month in SCE charges at current TOU rates. The net benefit after amortized cost is $139 to $162 per month.

With a 20-year loan at 7.99% on $24,000 (no ITC benefit until your next tax filing), your monthly payment is approximately $200. Your SCE savings are the same $195 to $218. In the first year before the ITC hits, your net position is roughly breakeven. After you apply the $7,200 credit to reduce your loan balance, the monthly payment drops substantially and the savings margin widens.

Leases: Fixed Monthly Payment, No Ownership

A solar lease charges you a fixed monthly fee, typically $80 to $140 per month for an 8 kW system in Temecula, regardless of how much electricity the system produces. Your SCE bill drops because the system offsets some of your usage, but you pay the lease on top. Contracts usually include a 1% to 3% annual escalator, meaning the monthly payment increases each year.

The installer claims the 30% ITC, the California property tax exclusion, and any available utility incentives. Those benefits lower the installer's cost basis and allow them to offer a monthly rate below what your electricity would cost from SCE. The savings are real but significantly smaller than what an owner captures.

Lease contracts run 20 to 25 years. At the end of the term, you can purchase the system at fair market value, renew the lease, or have the panels removed. Most contracts require you to maintain the panels and the roof area beneath them in good condition throughout the term.

PPAs in Temecula: Rare in 2026 and Why

A power purchase agreement (PPA) is structurally similar to a lease except you pay per kilowatt-hour produced rather than a flat monthly fee. A typical PPA rate in Southern California used to be 10 to 14 cents per kWh, well below SCE's retail rate of 28 to 34 cents. Under NEM 2.0, that spread was attractive enough for installers and customers alike.

NEM 3.0, effective for all new solar interconnections after April 14, 2023, dramatically reduced the value of daytime solar exports. The Avoided Cost Calculator rate paid by SCE for excess solar dropped from approximately 28 cents per kWh to 5 to 8 cents per kWh. That reduction compressed the margin available to PPA providers in SCE territory. As a result, most solar companies operating in Temecula and Murrieta have stopped offering PPAs for residential customers entirely. If you are quoted a PPA in 2026, ask the company how they are making the numbers work under NEM 3.0 before signing anything.

What Happens at Resale

Owned solar systems, whether purchased with cash or a loan, are generally treated as a home improvement that adds value. Studies by Lawrence Berkeley National Laboratory found that solar adds approximately $4 per watt of installed capacity to home resale prices in California, suggesting a Temecula 8 kW system could add $32,000 in resale value. The reality varies by market and buyer, but owned solar rarely complicates a sale.

Leased systems are a different matter. Lease contracts are not tied to the current homeowner; they transfer with the property. A buyer must agree to assume the remaining lease term, often 10 to 18 years. Some buyers will not do this, especially if the remaining payments total $15,000 or more. Others negotiate a price reduction to account for the obligation. Real estate agents in Temecula report that listings with solar leases take longer to close and sometimes require the seller to pay off the lease buyout to facilitate the sale. Lease buyout prices in the first 10 years are typically $20,000 to $35,000.

When Leasing Still Makes Sense

Leasing is not always the wrong choice. It makes the most sense when you do not have sufficient federal tax liability to use the 30% ITC. The credit is nonrefundable, meaning you can only use it to offset taxes you actually owe. If your federal tax bill is under $5,000 per year, carrying forward the unused credit over multiple years reduces its present value. In those situations, letting the installer claim the credit and passing some savings to you through a lower lease rate may actually produce comparable net savings.

Leasing also makes sense if you are planning to sell the home within 3 to 5 years and want to avoid a large upfront loan commitment. In a rising electricity rate environment, locking in a fixed or slow-escalating lease rate provides some protection, though you give up the long-term equity benefit.

5 Questions to Ask Any Installer About Their Financing

Before signing any solar financing agreement in Temecula or Murrieta, get clear answers to these questions:

1. What is the cash price versus the financed price? Any gap above 12% reflects a dealer fee you are paying through a higher loan balance.
2. Who claims the 30% federal tax credit? If the answer is anything other than you personally, you are in a lease or PPA structure regardless of how it is labeled.
3. What is the residual value or buyout schedule if I sell my home early? Get this in writing as a dollar figure for years 3, 5, 7, and 10.
4. Is there a prepayment penalty on the loan? Some specialty solar loans include prepayment fees if you refinance or pay off early. Standard home equity loans do not.
5. What happens to my NEM interconnection agreement if I refinance into a home equity loan later? The NEM agreement stays with the property, but understanding the lender's view on collateral and liens matters for planning.

The Bottom Line for Temecula and Murrieta Homeowners

For most homeowners in Temecula and Murrieta with a federal tax liability of $6,000 or more per year, a solar loan produces better long-term financial outcomes than a lease. You capture the 30% ITC, you own an asset that adds home value, and you eliminate a lease complication at resale. The total 25-year cost of ownership through a loan is typically $25,000 to $32,000 after the credit on an 8 kW system. The total 25-year cost of a lease on the same system is $28,000 to $42,000 in cumulative payments with nothing owned at the end.

If your tax situation or timeline makes ownership less advantageous, a lease can still cut your electricity costs meaningfully. The key is going in with clear eyes about what you are giving up and what you are getting in return.
