Solar Financing Options Explained: Cash, Loan, Lease, PPA & Subscription

December 31, 2025 was the last day a US homeowner could claim the Section 25D federal tax credit on a new solar purchase. Starting January 1, 2026, cash buyers and loan borrowers get nothing from the federal government — zero. Lease and PPA providers, meanwhile, still access Section 48E at 30% through the July 4, 2026 begin-construction deadline, and they pass those savings to customers as below-market rates. That asymmetry is reshaping every sales conversation happening right now.

For solar installers and sales reps, this means the financing script that worked in 2024 and 2025 needs a full rewrite. Customers who once defaulted to a loan because “the tax credit covers the interest” now face a longer payback. Third-party ownership (TPO) — leases and PPAs — already exceeded 50% of residential installs in the first half of 2025, according to SEIA’s January 2026 Guide for Residential Solar Installers. In some markets, TPO share had reached nearly 50% by summer 2025 (Source: EnergyScape Renewables).

This guide covers all five financing structures — cash, loan, lease, PPA, and community solar subscription — with real 2026 math on an 8 kW system and a five-question decision framework you can run through in a customer’s home. Whether you’re designing systems with solar design software or sitting at a kitchen table with a proposal printout, the numbers here are the ones that will close or lose the deal.

In this guide:

• How each of the 5 financing structures works — and the exact math for an 8 kW system in 2026
• Why the Section 25D expiration shifts the cash/loan equation and what Section 48E means for leases and PPAs
• How dealer fees inflate solar loan costs by 15–30% — and how to spot the markup before you sign
• How lease payment escalators compound over 25 years (with a side-by-side table)
• Which financing option is best for homeowners who plan to sell their house
• How to present all five options in a customer consultation using a 5-question decision framework
• Where community solar works best — and the states with the most active programs

The 2026 Financing Mix Has Shifted

The US residential solar market ran on the same playbook for a decade: customers buy or loan-finance a system, claim the federal ITC, and payback arrives in 6–9 years. That playbook expired with Section 25D on December 31, 2025.

In 2025, the market split roughly 63% solar loans, 22% cash purchases, and 15% TPO (Source: SEIA/Wood Mackenzie data cited by JouleIO). The loan-dominant share existed largely because zero-down loans paired with the 30% ITC made financing look like free money. Remove the ITC and a $22,000 loan at 7% APR with a 22% dealer fee costs $46,680 net over 25 years — compared to $61,400 net for a cash purchase. The math changed overnight.

On the TPO side, lease and PPA providers can still claim Section 48E (the commercial ITC) at 30% for projects beginning construction by July 4, 2026 (must be placed in service by December 31, 2030). (Source: IRS Notice 2025-42 via The Tax Adviser, 2026; SunwiseUSA, 2026). They pass those savings to customers as rates 20–40% below utility pricing from day one. A homeowner in a high-rate state choosing between a 7% loan and a PPA at $0.12/kWh is looking at a much tighter decision than they were two years ago.

Why Installers Need an Updated Sales Script

Most homeowners have not absorbed what the Section 25D expiration means in dollar terms. They still expect a federal tax credit. When a rep explains that the credit is gone for buyers — but not for lease/PPA customers — it reframes the entire conversation. The rep who can walk through the five financing options, show the 25-year numbers, and map the customer’s situation to the right structure will close more deals than the one still quoting “30% back from the government.” This guide is that script.

The Five Solar Financing Options at a Glance

The five main solar financing options are: (1) cash purchase — pay upfront, own the system, highest lifetime savings; (2) solar loan — $0 down, monthly payments, you own the system; (3) solar lease — fixed monthly rent, no ownership; (4) PPA — pay per kilowatt-hour produced; and (5) community solar subscription — offsite panels, bill credits, no installation required.

Each structure has a different risk-and-reward profile. The sections below go deeper into the math for each one. All models use an 8 kW system at $22,000 gross cost, 10,800 kWh/year annual production, and a national average utility rate of $0.1805/kWh escalating at 3% annually — with no federal ITC for residential buyers in 2026.

Option 1 — Cash Purchase

How It Works

A cash purchase means paying the full system cost upfront. The system is on the property title from day one. There is no lien, no monthly payment, and no lender to satisfy at closing. The owner captures 100% of the electricity production value through net metering credits or avoided utility charges.

For a home sale, owned solar transfers with the deed. The transaction is clean. No assumption paperwork, no credit check for the buyer, no provider approval required.

2026 Math — 8 kW System, No ITC

National average installed costs in 2026 range from $2.65/W (NREL Spring 2025 Solar Industry Update, Source: NREL, 2025) to $3.39/W (SEIA/Wood Mackenzie national average Q4 2025, Source: SEIA SMI 2025). LBNL pegs the median for cash-purchased systems at $3.5/W (Source: LBNL Tracking the Sun 2025 Data Update, 2024 installs).

For modeling, we use $22,000 gross — consistent with the $2.75/W midpoint across DOE, NREL, and EnergySage data for a standard residential system.

• Gross cost: $22,000
• Federal ITC: $0 (Section 25D expired December 31, 2025)
• Annual production: 10,800 kWh
• Annual savings at $0.1805/kWh: ~$1,950/year in year 1
• Simple payback: 11–14 years depending on utility rate trajectory
• 25-year electricity value captured: ~$67,400 (at 3% annual rate escalation)
• Home value increase: $16,000 ($4/W for 8 kW system, per LBNL)
• Net 25-year benefit: ~$61,400

Use solar shadow analysis software during site assessment to confirm the production estimate holds — shading that cuts yield by 15% stretches payback from 12 years to 14 years, which changes the recommendation.

Pros and Cons

Pros:

• Highest lifetime ROI of any structure
• No lien, cleanest home-sale transaction
• Owned solar can add value at resale (Source: WattBuild citing multiple studies, 2025)
• No dealer-fee markup embedded in the cost

Cons:

• Large capital requirement ($22,000+)
• No federal ITC available for residential buyers in 2026
• Opportunity cost on capital (money tied up instead of invested elsewhere)

When to Recommend It

Cash purchase fits clients who have $22,000+ in liquid capital with no higher-yield alternative, plan to own the home for 10+ years, and are in a state with a utility rate above $0.16/kWh. It is the highest-ROI path — the payback math is just slower in 2026 without the ITC.

Option 2 — Solar Loan

How It Works

A solar loan lets the buyer own the system from day one while financing the full purchase price. A bank or specialty lender pays the installer upfront; the homeowner repays the lender over 10–25 years. Ownership — and all equity value — sits with the buyer from the moment the system is installed. The most common product is an unsecured personal loan, but several structures exist.

Loan Types and APR Ranges

APR ranges sourced from JouleIO (2026) and NuwattEnergy.

The Dealer Fee Trap — What Inflates the Loan

Most loan reps never explain this — and they should. A dealer fee (also called a buy-down fee or origination markup) is a charge the solar company pays to the lender in exchange for a lower advertised APR. The fee is rolled into the amount the customer finances, not shown as a line item on the contract.

Typical dealer fees run 15–30% of the cash price, with an average around 22–25% (Source: SolarReviews, 2025; EnergySage, 2023). Some lenders push 30–40%, which consumer advocates have flagged as a risk (Source: EnergyScape Renewables).

The LBNL data is stark: loan-financed systems are priced at a median $4.7/W vs $3.5/W for cash purchases — a $1.2/W gap driven almost entirely by dealer fees (Source: LBNL Tracking the Sun 2025 Data Update, 2024 installs). On an 8 kW system, that is $9,600 in additional financing cost before a single interest payment.

2026 Math — 8 kW, 7% APR, 15-Year Term, 22% Dealer Fee

• Financed amount: $26,840 (after 22% dealer fee)
• Monthly payment: ~$241
• Annual savings offset (year 1): ~$1,950
• Net annual cash flow (savings minus payment): ~−$942 for first 3–4 years
• 25-year net benefit: ~$46,680
• Versus cash: trails by ~$14,720 over 25 years

The break-even on cumulative benefit vs cash purchase arrives around year 18–20, depending on utility rate escalation. This is the conversation a rep must be prepared to have. See loan, cash, and PPA modeling for a deeper look at the amortization mechanics.

Pros and Cons

Pros:

• $0 down, system ownership from day one
• Builds home equity value
• Can be refinanced if rates drop
• Avoids long-term TPO contract restrictions

Cons:

• Dealer fees inflate true cost significantly
• No federal ITC for residential buyers in 2026
• Total interest cost is higher than cash purchase by $14,720+ in our model
• Monthly payment creates negative cash flow for first several years

When to Recommend It

A loan works when the client has a 680+ FICO score, no cash reserves but strong income, and the dealer fee is disclosed and under 20%. Long tenure (12+ years) and a utility rate above $0.16/kWh are necessary conditions. If the dealer fee is above 25%, run the PPA math alongside — the customer may come out ahead with TPO.

Option 3 — Solar Lease

How It Works

A solar lease is a rental agreement. The customer makes a fixed monthly payment for the use of panels the provider owns. The provider handles operations, maintenance, and insurance for the full contract term — typically 20–25 years. The customer buys no asset; they buy the convenience of solar electricity at a predictable rate.

Two variants exist. A standard lease charges a monthly rent that may increase each year by an escalator rate. A prepaid lease (also called a prepaid PPA) accepts a lump sum upfront — often at a 30% discount to the lifetime monthly payments — in exchange for no further monthly obligations. Prepaid leases are gaining share in California under NEM 3.0 because they avoid the escalator risk entirely.

The provider claims Section 48E in 2026 and passes part of that savings to the customer through a rate set below the local utility price. The customer does not claim any ITC.

The Escalator Risk — Compounding Over 25 Years

The escalator rate is the annual percentage increase built into a lease or PPA contract. Mainstream escalators run 0.9%–2.9% (Source: GreenSun NJ; Solar.com). The industry recommends avoiding contracts above 2%.

At 2.9%, a $100/month starting payment becomes $202/month by year 25. That $202 may still be below the utility rate if electricity prices have climbed — but the margin narrows, and if the utility builds more renewables and rates flatten, the customer loses the arbitrage they signed up for.

2026 Math — 8 kW, $120/Month Start, 2% Escalator

• Year 1 payment: $1,440/year ($120/month)
• Year 10 payment: ~$1,716/year
• Year 20 payment: ~$2,093/year
• 25-year total payments: ~$30,600
• 25-year electricity value captured: ~$67,400
• 25-year net benefit: ~$36,800 (electricity value minus payments)
• Versus cash: trails by ~$24,600 over 25 years

The lease looks worse on a 25-year ROI basis, but it has a faster apparent break-even vs doing nothing — savings begin from month one with $0 upfront.

Transferability When Selling the Home

When a homeowner with a lease wants to sell, three outcomes are possible:

1. Lease assumption — the buyer takes over the remaining contract (requires credit check and provider approval)
2. Buyout — the seller pays the provider’s fair market value to purchase the system outright
3. Panel removal — the provider removes the panels; the seller pays removal costs and the home loses the solar value

NAR’s 2024 REALTORS® and Sustainability Report found that 49% of agents listed “understanding how solar panels impact a transaction” as a market issue, and 43% cited “valuation of solar panels on homes” (Source: NAR, 2024). The credit check requirement can kill a transaction if the buyer doesn’t qualify. Leased solar adds near-zero to appraised home value because Fannie Mae and Freddie Mac guidelines exclude third-party-owned systems from valuation (Source: WattBuild citing GSE guidelines, 2025).

When to Recommend It

A lease makes sense when the customer cannot qualify for a loan and wants $0 down. It is also the right call for someone planning to sell in 5–10 years who can negotiate a lease assumption clause and is in a state with a utility rate above $0.20/kWh — the deeper discount buffer protects the value even if the buyer negotiates.

Option 4 — Power Purchase Agreement (PPA)

How It Works

A power purchase agreement (PPA) is distinct from a lease in one key way: the customer buys the kilowatt-hours the system produces, not the use of the panels. If the system underperforms due to equipment failure or shading, the customer pays less. If it overproduces, they pay more. Production risk sits with the provider.

Typical residential PPA rates run $0.08–$0.25/kWh depending on region and provider (Source: SolarTechOnline, 2025). The standard discount vs local utility rates is 10–30% (Source: Solar.com). In 2026, with Section 48E pass-through, the discount from providers can reach 20–40% from day one (Source: SunwiseUSA, 2026).

PPAs also typically include an annual escalator rate, usually 1–3%. Model the same compounding risk as a lease.

PPA Rates vs Utility Rates — Regional Snapshot

California utility data as of April 2026 (Source: EnergySage, April 2026; NRG Clean Power, 2026). National average utility rate from ElectricChoice/EIA, April 2026.

The PPA discount is powerful in high-rate markets. In Oklahoma at $0.11/kWh, a PPA at $0.09/kWh saves only $0.02/kWh — barely worth the 20-year contract. In California at $0.34–$0.45/kWh, the same PPA structure saves $0.15–$0.28/kWh. Utility rate is the single biggest variable in the PPA decision.

State PPA Availability

PPA legality varies by state utility commission. PPAs are widely available and common in California, New York, Massachusetts, Arizona, New Jersey, Colorado, Texas, Nevada, Washington, and Oregon. Some states have restrictions or limited availability — Florida, Wisconsin, Kentucky, North Dakota, South Dakota, and Oklahoma historically restrict or complicate PPAs, though this changes as regulatory decisions update. Always verify with the state’s public utilities commission before quoting a PPA product. No single authoritative source maintains a live national PPA legality map — instruct reps to check the state commission directly.

2026 Math — 8 kW, $0.12/kWh PPA Rate, 2% Escalator

• Year 1 production: 10,800 kWh × $0.12/kWh = $1,296/year ($108/month)
• Year 10 PPA rate: ~$0.146/kWh
• Year 20 PPA rate: ~$0.178/kWh
• 25-year total PPA cost: ~$28,200
• Utility alternative cost (3% escalation over 25 years): ~$67,400
• 25-year net benefit: ~$39,200

The PPA edges out the lease in this model by ~$2,400 because the starting rate ($0.12/kWh) produces lower year-1 payments than the lease’s $120/month on the same system. The lower base compounds favorably over 25 years.

When to Recommend It

A PPA fits customers in high-rate states where the discount is 30%+ of their current bill, who cannot qualify for a loan, do not want ownership, and are in a state where PPA is legally available. They must have stable long-term plans or a clear understanding of the transfer options if they sell.

Option 5 — Community Solar Subscription

How It Works

Community solar lets customers subscribe to a share of an offsite solar array. No panels are installed on their property. The utility applies bill credits to the subscriber’s account each month through virtual net metering — the array’s production is allocated to subscribers proportionally, and the utility reduces each bill by the credited amount.

Two subscription models exist. An ownership share means the subscriber purchases a fractional portion of the array and receives credits tied to that system’s output for 20–25 years. A pure subscription charges a monthly fee (usually a flat rate or a rate per kWh of allocated production) and can be cancelled with 30–90 days notice. The pure subscription is more flexible and more common for residential customers.

Community solar requires no roof assessment, no HOA approval, no installer visit. A customer who rents, owns a condo, has a heavily shaded roof, or simply does not want the complexity of rooftop solar can participate today in any state with an active program.

Savings Range and Economics

Typical savings run 5–20% of annual electricity costs (Source: EnergySage). The most common range is 10–15%, with some programs offering up to 25% (Source: RevisionEnergy).

The NREL median net present value of community solar subscriptions through mid-2024 was +$0.27/W-AC for subscribers (Source: DOE Community Solar Market Trends / NREL Sharing the Sun, 2024). Cumulative US community solar capacity reached approximately 10.6 GW-AC in 2024 (Source: NREL Spring 2025 Solar Industry Update).

For a homeowner spending $2,400/year on electricity ($200/month), a 12% community solar discount saves ~$288/year. That is modest compared to rooftop ownership’s ~$1,950/year in avoided costs. Position community solar as the best option for people who cannot do rooftop — not as a replacement for those who can.

Best States for Community Solar

When to Recommend It

Recommend community solar when the customer rents or owns a condo, has a shaded or structurally compromised roof, faces HOA restrictions, or simply wants zero installation complexity. It is also the right answer for customers who want to go solar today in a state where rooftop PPA is not available. The tradeoff is lower lifetime savings compared to ownership, but the barrier to entry is near zero.

Side-by-Side: 25-Year Financial Model

Reading the table:

Cash wins on lifetime ROI — it is not close. The ~$14,720 gap between cash and loan is mostly dealer fees and interest, not hardware. PPA edges out lease by ~$2,400 over 25 years because the per-kWh starting rate is lower than the equivalent monthly lease payment. Community solar does not compare directly — there is no installation cost to amortize, but the savings ceiling is lower.

Every scenario narrows when state rates change. A customer in Massachusetts at $0.31/kWh sees shorter payback and better TPO discounts across the board. A customer in Louisiana at $0.10/kWh sees extended cash payback and weaker PPA economics. This is exactly why running scenario-specific outputs with a generation and financial tool matters more than any generic table.

The 5-Question Decision Framework for Sales Reps

Run through these five questions in order. The framework takes about 10 minutes and routes a customer to the right option without the rep needing to pitch all five structures unprompted.

Q1 — Does the Customer Have $22K+ Liquid, or Qualify for a Loan at Under 7% APR?

If the answer is yes to cash: evaluate Option 1 first. Run the generation and financial tool to model their specific system, rate, and payback. Cash is the highest-ROI path in 2026.

If yes to loan: get the dealer fee disclosed before presenting monthly numbers. If the fee is above 20%, show the PPA math side by side. If the fee is under 20% and the APR is under 7%, loan ownership is still a solid path.

If no to both: skip to Question 5 — the customer needs a $0-down option.

Q2 — Do They Plan to Stay in This Home for 12+ Years?

Yes means ownership (cash or loan) maximizes lifetime ROI. The break-even for a cash purchase is 11–14 years. Customers who stay longer than the payback period capture the full long-term upside — ~$61,400 over 25 years.

No, or uncertain: lease, PPA, or community solar avoids the stranded-asset risk of a lien or an asset they may have to sell at a discount.

Q3 — Is Their Utility Rate Above $0.16/kWh With Favorable Net Metering?

Above $0.16/kWh: rooftop ownership has good payback economics. Below $0.16/kWh, a cash purchase stretches to 16+ years payback without the ITC. TPO may still make economic sense at these rates because the provider’s Section 48E economics are independent of the customer’s rate.

Net metering terms matter here too. In California under NEM 3.0, export credits dropped significantly — customers on SCE, PG&E, and SDG&E get far less for energy sent to the grid. Self-consumption and battery storage become more valuable. This changes the yield model for ownership.

Q4 — Is a PPA Available in Their State?

Yes, and the utility rate discount is 30%+: PPA is often the best $0-down option, beating the lease on 25-year NPV by ~$2,400 in the base model and more in high-rate markets.

No PPA available: move to lease or community solar. If the customer is in one of the five active community solar states (NY, NJ, IL, MA, MN), community solar may be easier than navigating a lease transfer at sale.

Q5 — Do They Rent, Have a Shaded or HOA-Restricted Roof, or Want Zero Maintenance?

Any single yes here points to community solar or a lease with full maintenance transfer. Community solar is the default answer for renters — there is no installation, no contract tied to the property, and no complication at move-out.

For a roof that is structurally sound but heavily shaded, run the shading analysis first using solar software before routing to TPO — a well-designed system on a partially shaded roof may still hit viable economics with microinverters.

Selling a Home With Solar — What Every Rep Must Disclose

The second-most-common objection in a solar sale is: “What happens when I want to move?” Here is the answer for each structure.

Owned Solar (Cash or Loan)

Owned solar transfers with the deed. The system adds value at resale — homes with solar sell for an average of 6.9% more than non-solar homes according to recent market analysis (Source: WattBuild citing multiple brokerages and valuation studies, 2025). On a $400,000 home, that is a $27,600 premium.

If the system was loan-financed and the lien is still active, it must be paid off at closing or — rarely — assumed by the buyer. Most buyers do not want to assume a solar lien, so plan for payoff at sale.

Leased Solar or PPA

Three outcomes are possible at sale:

1. Assumption — the buyer takes over the remaining lease or PPA. They must pass a credit check from the provider. If they fail, the deal may fall through.
2. Buyout — the seller pays the provider’s fair market value to purchase the system outright, then the system transfers as owned.
3. Removal — the provider removes the panels. Removal costs vary by provider; this is the least common outcome and the seller typically absorbs the cost.

NAR’s 2024 REALTORS® and Sustainability Report found that 49% of agents listed “understanding how solar panels impact a transaction” as a market issue (Source: NAR, 2024). The credit check requirement can kill a transaction if the buyer is borderline. Instruct sellers to start the transfer process 60–90 days before listing — not at closing.

Community Solar

A community solar subscription is tied to a utility account, not the property. When the homeowner sells, they cancel the subscription with 30–90 days notice per the contract terms, or transfer the utility account to the buyer who can decide independently. This is the least-friction structure in a home sale of the three.

Commercial and Industrial (C&I) Financing — Quick Reference

C&I solar financing follows the same five structures but with different tax incentive math that tilts heavily toward owned systems.

Cash and Loan for C&I

Business owners who purchase a solar system outright can claim Section 48E at 30% (through July 4, 2026 begin-construction deadline) plus MACRS 5-year accelerated depreciation. Combined, this recovers 45–55% of total project cost in years 1–5 for a qualifying project (Source: SunwiseUSA, 2026).

Commercial loan rates run 5.5–8.5% depending on credit quality and term. The combination of Section 48E + MACRS makes ownership far more attractive for C&I buyers than it is for residential buyers in 2026.

A reference project: a 360 kW commercial system in Texas at $612,000 gross, with 48E + MACRS, sees effective year-1 cost recovery close to $280,000 (Source: CommercialSolarMatch). That changes the payback math completely relative to residential.

Lease and PPA for C&I

Section 48E is fully available for TPO developers through the July 4, 2026 begin-construction deadline, with placement in service required by December 31, 2030 (Source: IRS Notice 2025-42 via The Tax Adviser, 2026). Projects beginning construction after July 4, 2026 must be placed in service by December 31, 2027 to qualify under a shortened safe harbor.

MACRS + 48E creates strong economics for TPO providers who then offer business customers below-market PPA rates — typically $0.06–$0.12/kWh for C&I contracts. Businesses with weak tax appetite (nonprofits, government entities, loss-carrying companies) often prefer PPA because they cannot use the ITC themselves.

For larger C&I projects exploring structured TPO deals, VPPA (virtual power purchase agreement) contracts are an additional option worth understanding — they separate the financial hedge from the physical energy delivery, which matters for multi-site commercial buyers.

Frequently Asked Questions

What are the solar financing options?

The five main solar financing options are cash purchase, solar loan, solar lease, power purchase agreement (PPA), and community solar subscription. Cash and loan buyers own the system; lease and PPA customers do not. Community solar requires no rooftop installation at all. Each option has different upfront costs, ownership rights, and long-term economics — see the 25-year comparison table in this guide.

Is it better to buy or lease solar panels in 2026?

Buying produces a higher 25-year net benefit — roughly $61,400 for cash vs $36,800 for a lease in our 8 kW model. However, cash and loan buyers lost the Section 25D federal tax credit after December 31, 2025, which extends payback periods by 3–5 years. Leasing wins for customers who cannot qualify for a loan, want $0 down, and prefer the provider to handle maintenance.

What is a solar dealer fee and how does it affect my loan?

A dealer fee is a markup a solar company charges a lender — typically 15–30% of the cash price — to buy down the loan’s APR. The fee is rolled into the financed amount, not shown as a line item. On a $22,000 system with a 22% dealer fee, the borrower finances $26,840 instead of $22,000 and pays roughly $4,800 more in total interest over 15 years. LBNL data confirms loan-financed systems cost $1.2/W more than cash-purchased systems — most of that gap is dealer fees.

Can I sell my house if I have a solar lease or PPA?

Yes, but the process is more complex than selling with an owned system. The buyer must either assume the lease or PPA (subject to a credit check), you buy out the contract at fair market value, or the provider removes the panels. NAR surveys show that understanding how solar panels impact a transaction is a top market issue for agents. Start the transfer process 60–90 days before listing to avoid closing delays.

Is solar still worth it without the federal tax credit in 2026?

For residential buyers, Section 25D expired December 31, 2025 — there is no federal tax credit in 2026. Without the credit, payback periods extend by 3–5 years. However, rising utility rates and continued hardware cost declines still produce positive ROI in most high-rate states. Lease and PPA customers are unaffected because their providers claim Section 48E, which is still active.

How does community solar work and how much can I save?

You subscribe to a share of an offsite solar array; the utility applies bill credits to your account each month via virtual net metering. No panels are installed on your property. Typical savings are 5–20% of annual electricity costs (Source: EnergySage), with 10–15% the most common range. Programs are most active in New York, Massachusetts, New Jersey, Illinois, and Minnesota.

Conclusion

The 2026 financing decision is not simpler than it was in 2024 — it is harder. Cash buyers face longer payback without the ITC. Loan borrowers face dealer fee exposure that most reps still do not disclose cleanly. Lease and PPA customers get the Section 48E pass-through but give up ownership and home equity value. Community solar offers an entry point for everyone else.

Our take is that the right answer always depends on three variables the generic articles ignore: the customer’s specific utility rate, their credit profile, and how long they plan to stay in the home. A rep who treats those as data inputs — not assumptions — closes deals the generic pitch misses.

The five-question framework above takes 10 minutes. The financial model in the generation and financial tool takes another 5. Together, that is the updated sales script for 2026.

Once you know which financing option fits your client, build the branded solar proposal software that closes the deal — with financing comparisons, production estimates, and your company’s branding in one document.
