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

Temecula's rental market is tight, SCE bills are high, and solar incentives are significant. But the financial structure of solar on investment property is completely different from installing it on a primary residence. This guide covers the landlord-tenant split problem, NEM 3.0 implications for landlords, virtual net metering for multi-unit buildings, the right financing structure, Section 48E tax credits for rental property, and how solar actually affects your cap rate in this market.

The Landlord-Tenant Solar Split Problem

The single biggest obstacle to solar adoption on rental property is a structural misalignment: the landlord pays the installation cost, but the tenant captures the electricity savings. In a standard single-family rental or small multifamily building where each unit has its own SCE meter, the tenant pays SCE directly. Solar installed on the roof reduces that bill. The tenant's cost goes down. The landlord's mortgage, property taxes, and insurance costs stay the same. The landlord spent $25,000-40,000 and sees no direct financial benefit unless they have restructured the lease.

This split incentive problem is well-documented in residential real estate research and it is the primary reason solar penetration on rental properties in California lags solar penetration on owner-occupied homes by a wide margin. But there are solutions, and the economics are changing in ways that make some of those solutions more attractive in Temecula specifically.

The main paths landlords use to close the split incentive gap are:

• Utilities-included leases: the landlord pays SCE directly and builds the electricity cost into the rent. With solar, the landlord's electricity cost drops, and the landlord captures the savings. This works best on single-family rentals where total electrical load is predictable.
• Master-metered multifamily: the landlord has one SCE meter for the whole property and charges utilities back to tenants as part of rent. Solar reduces the master meter bill. The landlord benefits directly.
• Virtual Net Metering: for properties where tenants have separate meters and pay SCE individually, California's VNM program allocates solar credits directly to each tenant's meter. Detailed in the next section.
• Solar as a rental premium: even when tenants pay their own bills, a home with solar in Temecula can command higher rent because tenants understand their SCE costs. A tenant paying $220/month in summer electricity bills versus $40/month with solar may rationally pay $100-150/month more in rent for the solar-equipped unit.

How NEM 3.0 Changes the Landlord Calculus

Under the old NEM 2.0 program, solar on a rental property where the landlord paid utilities was a simpler financial case. Excess solar production exported to the grid received close to retail credit, roughly 28-30 cents per kWh. That made it possible to right-size a solar system and essentially zero out the electricity bill for the property, with excess production banking against future consumption.

NEM 3.0, which applies to all new solar systems interconnected after April 14, 2023, replaced retail-rate export credits with the Avoided Cost Calculator rate. ACC export rates average 5-8 cents per kWh. That change has two implications for landlords:

First, oversizing a solar system is now a poor investment. Under NEM 2.0, a system that produced more than the property used simply banked the excess at near-retail value. Under NEM 3.0, that excess earns 5-8 cents. A landlord installing solar now needs to size the system to match consumption precisely, not to generate a surplus.

Second, the economic case for battery storage on rental property strengthened considerably under NEM 3.0. A battery captures the difference between the 5-8 cent export rate and the 28-47 cent import rate during evening hours. On a utilities-included rental, every kilowatt-hour the battery prevents importing from the grid during the 4pm-9pm on-peak window saves roughly 30-40 cents instead of the 20-22 cents it saved under NEM 2.0 credit structures. The payback on battery storage at rental properties improved significantly after NEM 3.0.

Virtual Net Metering for Multi-Unit Properties

California's Virtual Net Metering program, administered by SCE in most of the Temecula and Murrieta service territory, is designed specifically for multifamily properties where tenants have individual meters. VNM allows a single solar array on a shared roof to allocate production credits across multiple tenant accounts.

Here is how it works in practice. Say you own a four-unit apartment building in Murrieta with a shared roof. You install a 16 kW solar array on that roof. Each of the four tenants has their own SCE meter and pays their own electricity bill. Under standard NEM, the solar would need to go on one meter (probably the landlord's common area meter), and the other three tenants see no benefit.

Under VNM, you designate how the solar production is allocated across all meters at the property. You might allocate 25% to each of the four tenant meters. Each tenant's SCE bill receives a credit each month for the solar production attributed to their unit. The tenants see lower bills without doing anything. You, as the landlord, negotiated leases with higher rents knowing the tenants would receive that bill credit.

VNM eligibility requirements for SCE customers include: all meters must be at the same premises, all meters must be with SCE, and the system must be interconnected under a valid NEM agreement. The landlord submits the allocation percentages to SCE, which can be adjusted annually. VNM allocations can also be set up so the landlord retains a portion for common area lighting, laundry rooms, or other landlord-paid loads.

VNM is one of the cleanest solutions to the split incentive problem because it does not require a utilities-included lease structure. The tenants benefit directly. The landlord can justify a rent premium for the VNM allocation without the complexity of managing electricity bills.

Lease vs Loan vs PPA for Landlords

The financing structure you choose significantly affects who captures the tax benefits and how the system is treated on sale of the property.

Solar loan (owned system). You borrow to purchase the system outright. You own the panels. You capture the Section 48E commercial tax credit (30% of system cost) directly. The system becomes part of the real property and can be appraised as part of the property value. On sale, the system transfers with the property. This is the structure that maximizes tax benefits and long-term property value for landlords.

Solar lease. You lease the equipment from a solar company for 20-25 years. The solar company owns the panels and claims the tax credits. You pay a fixed monthly lease payment in exchange for the electricity the panels produce. The lease payment is typically lower than your previous electricity bill, creating a cost reduction. On sale of the property, the lease either transfers to the buyer or must be bought out. Lease assumptions can complicate real estate transactions.

Power Purchase Agreement (PPA). Similar to a lease but you pay for the electricity produced rather than the equipment. A solar company installs panels on your property at no upfront cost, and you agree to purchase the electricity at a rate below SCE's retail rate for 20-25 years. PPAs on rental properties can solve the split incentive by placing the panels at the property level while the landlord pays below-market rates, but the PPA must be carefully structured for properties with tenant-paid utilities. PPA transfers at sale require buyer qualification and consent.

For most Temecula landlords with long investment horizons, a solar loan with outright ownership captures the most value. The Section 48E commercial credit reduces upfront cost by 30%, the system adds appraised property value, and there is no lease transfer complication at sale. A lease or PPA makes more sense when capital preservation is the priority or when the landlord's tax situation limits the value of the investment credit.

Section 48E Commercial Tax Credit: What Landlords Can Actually Claim

The tax credit situation for solar on rental property is one of the most misunderstood aspects of residential real estate investing in California.

The residential solar tax credit, officially called Section 25D of the Internal Revenue Code, provides a 30% credit on the installation costs of solar panels on a taxpayer's primary residence. The word "primary" is the operative term. Section 25D explicitly does not apply to rental, vacation, or investment properties. A landlord who installs solar on a rental home in Murrieta cannot claim the Section 25D credit.

However, Section 48E of the Internal Revenue Code is a different credit entirely. Section 48E is the commercial and investment clean energy credit, and it does apply to solar installed on rental and investment property. The base credit rate under Section 48E is 30% of qualified installation costs for solar photovoltaic systems placed in service after January 1, 2025.

To claim Section 48E, the system must be placed in service at a property used in a trade or business or for the production of income. A rental property qualifies because renting real estate is an income-producing activity. The credit reduces federal income tax liability dollar-for-dollar. Unlike Section 25D, Section 48E credits can be carried forward to future tax years if the credit exceeds the taxpayer's tax liability in the year the system is placed in service.

There are additional bonus credits under Section 48E for systems that use domestically manufactured components and for projects in energy communities. These bonuses can push the effective credit rate above 30% in qualifying circumstances. A tax professional familiar with real estate investment and energy tax credits is essential for rental property solar projects where the Section 48E credit is material to the investment return.

Solar and the Temecula Rental Market

Temecula and Murrieta represent one of the more compelling rental market contexts for solar investment in Southern California. Several factors compound here in ways that improve the landlord's return on solar.

SCE electricity rates are among the higher residential rates in the United States. On the TOU-D-PRIME schedule, electricity costs 34.5 cents per kWh during the summer on-peak window. For a three-bedroom single-family rental running central air through a Temecula summer, monthly electricity bills of $250-350 are common. Tenants in Temecula understand high SCE bills. A solar-equipped rental where tenants face $30-60 bills in summer instead of $250-350 is a differentiated product in the local market.

Vacancy rates in Temecula have remained relatively low compared to Southern California averages, partly driven by the quality of the school district, proximity to the 15 freeway corridor, and the demand from military families at Camp Pendleton. Lower vacancy means landlords can capture a solar-driven rent premium without worrying about units sitting empty.

The climate is solar-favorable. Temecula averages approximately 280 sunny days per year. A 6 kW residential solar system in Temecula generates approximately 9,000-10,000 kWh annually, compared to 7,500-8,500 kWh for the same system in Seattle or a comparable northern market. More production from the same installed capacity means better return on investment.

How Solar Affects Property Value and Cap Rate

Two different valuation frameworks apply depending on whether the property is valued as comparable sales or as an income-producing asset.

Comparable sales approach. Lawrence Berkeley National Laboratory research found that owned solar systems added an average of approximately $4 per watt of installed capacity to residential sale prices. For a 6 kW system, that implies roughly $24,000 in additional value. A 10 kW system implies $40,000. These figures come from a nationwide dataset and California properties showed higher solar premiums than the national average.

The comparable sales premium is harder to realize on rental property because many buyer pools for income property primarily value the income approach rather than the improvement premium. But as solar becomes standard on Temecula homes, a solar-equipped rental may not command a premium so much as an unequipped rental carries a discount.

Income approach and cap rate. On a utilities-included rental, solar reduces the landlord's operating expense. Each dollar reduction in operating expenses becomes a dollar of additional net operating income. At a 5.5% cap rate, which is reasonable for a Temecula single-family rental in 2026, an annual $1,800 reduction in electricity costs adds $32,700 in property value.

The arithmetic: a $30,000 solar installation that saves $1,800 per year in electricity (net of system costs, after the Section 48E credit reduces net cost to around $21,000) adds $32,700 in income-approach value against a $21,000 net cost. The return is compelling when the transaction is structured correctly.

PACE Financing for Temecula Landlords

Property Assessed Clean Energy financing is worth understanding for landlords who want to install solar without using cash or conventional debt.

PACE works by attaching the solar financing to the property as a special assessment, collected through the property tax bill over 5-30 years. The financing company pays the solar installer at project completion. You repay through your property tax in semiannual installments. Because the assessment is secured by the property rather than by your personal credit, PACE approvals are based primarily on property equity and not on income or credit score.

For rental property specifically, PACE has a notable characteristic: the assessment is tied to the property, not the owner. When you sell the property, the assessment either transfers to the buyer or is paid off from sale proceeds, similar to a mechanics lien or property tax bill. Some buyers may view a PACE assessment as unattractive because it sits senior to first mortgage financing in many structures. Disclose a PACE assessment clearly in any sale.

PACE programs serving Riverside County include Ygrene Energy Fund and CalFirst Bankcorp programs. Interest rates on PACE financing are typically higher than conventional solar loans, often running 6-9% in a 2026 rate environment. The tradeoff is zero upfront capital and no income qualification. For a landlord with equity in the property but limited liquid capital, PACE can make a solar installation financially accessible when a bank loan would not close.

What to Do Before You Commit

Before signing a solar contract for a rental property in Temecula, four steps will protect your investment.

Confirm the tax treatment with a CPA. Section 48E eligibility, passive activity rules, and depreciation treatment (MACRS applies to solar installed on income-producing property) vary by the investor's tax situation. Do not rely on the solar salesperson's explanation of the tax benefits. Get written confirmation from your tax advisor before signing.

Review your lease structure. If tenants currently pay utilities directly to SCE, decide now whether you will switch to utilities-included, apply for VNM, or position the solar as a rental premium driver. Each path requires different lease language and different expectations set with tenants.

Get a production estimate tied to actual consumption. Request 12 months of SCE interval data from the property's meter (you can obtain this as the property owner) and ask your installer to size the system against actual usage rather than a generic square footage estimate. Under NEM 3.0, an oversized system is a wasted investment.

Compare financing options explicitly. Get quotes for both a solar loan (owned system) and a PPA or lease, model the Section 48E credit for the owned option, and calculate the net present value of each path over a 10-year hold period. The right answer depends on your capital position, tax situation, and investment horizon.

Frequently Asked Questions

Can a landlord in Temecula claim the federal solar tax credit on a rental property?

The residential Section 25D credit (30%) applies only to primary residences. It does not apply to rental property. However, Section 48E, the commercial investment tax credit, provides a 30% credit on solar installed on income-producing property, which includes rental real estate. Consult a tax professional to confirm eligibility for your specific situation.

What is the landlord-tenant solar split problem?

The split problem is the misalignment between who invests in solar (the landlord) and who receives the electricity bill savings (the tenant). Solutions include utilities-included leases where the landlord pays SCE directly, California's Virtual Net Metering program that allocates solar credits to tenant meters, or positioning solar as a rent premium driver since tenants in Temecula understand high SCE bills.

What is virtual net metering and does it apply to Temecula rentals?

Virtual Net Metering (VNM) is a California program that allocates solar production credits from a single array across multiple tenant meters at the same property. SCE administers VNM in most of the Temecula and Murrieta service area. It allows tenants with separate meters to see direct bill reductions from a shared solar installation, solving the split incentive problem without requiring a utilities-included lease.

How does solar affect property value and cap rate for Temecula rental properties?

Lawrence Berkeley National Laboratory research found solar adds approximately $4 per installed watt to residential property values. For income-approach valuation, each $1,800 per year in reduced operating costs adds approximately $32,700 in property value at a 5.5% cap rate. A $30,000 solar installation with a Section 48E credit bringing net cost to roughly $21,000 can add more value than it costs when structured correctly on a utilities-included rental.

What is PACE financing and can Temecula landlords use it for solar?

PACE (Property Assessed Clean Energy) financing attaches solar costs to the property as a special assessment repaid through property tax bills over 5-30 years. Approval is based on property equity rather than personal credit. PACE is available to landlords and investors in Riverside County through programs including Ygrene. Interest rates run higher than conventional solar loans (6-9%), but the zero-upfront-capital structure makes solar accessible when conventional financing is not.
