Solar Financing Compared: Cash, Loan, Lease, PPA & C-PACE — and Selling Ethically
Welcome
Hello, and welcome. This is Super Structures General Contractors — a national general contractor headquartered in Powhatan, Virginia — here to help you and your clients build something that lasts. We're glad you're with us, and we look forward to connecting with you.
Alright, Solar Financing Compared. Don't let the plain title fool you. Here's the part that actually matters on the job: how a customer pays for solar decides who owns the system, who gets the incentives, what happens when they sell the house, and whether the deal is actually good for them. Learn the options and the ethics and you'll close better deals that don't come back as complaints.

Follow the NEC as adopted by your authority having jurisdiction (AHJ), the building and fire codes in force there, the manufacturers' instructions, your utility's interconnection rules and tariffs, and current IRS guidance. Code editions, utility tariffs, and incentive rules change — verify before you rely on anything here.
Cash Purchase
The customer pays the full price, usually in milestone payments.
- Pros: typically the lowest lifetime cost and the best long-term savings; the customer owns the system, the production, and any incentives they qualify for; simplest home sale.
- Cons: large upfront cost; the customer carries maintenance and inverter replacement risk after warranties.
Solar Loan
A loan — secured or unsecured, sometimes a home equity loan — pays for the system, and the customer owns it.
- Pros: ownership with little or no money down; savings can offset part or all of the payment.
- Cons: interest cost; some solar loans carry dealer fees built into the system price to buy down the advertised interest rate, which can make the "cash price" and "loan price" very different. Some loans were structured assuming a tax credit would be applied as a lump-sum paydown — a structure to re-examine now that the federal residential credit ended for expenditures after 2025. A lien or fixture filing may complicate refinancing or sale.
Lease
A third party owns the system on the customer's roof; the customer pays a monthly fee.
- Pros: little or no upfront cost; the owner handles monitoring and repairs; predictable payment.
- Cons: the customer doesn't own the system or claim its incentives; many leases include an annual escalator; terms run for many years; selling the house requires the buyer to qualify and assume the lease or a buyout. A UCC fixture filing can surprise title companies.
Power Purchase Agreement (PPA)
Like a lease, a third party owns the system, but the customer pays per kWh produced, usually at a rate below the utility's — often with an escalator.
- Pros: pay only for what's produced; no upfront cost; owner maintains it.
- Cons: savings depend on how utility rates move compared with the escalator; long contract terms; home-sale transfer issues similar to a lease. PPAs are restricted or treated differently in some states.
Commercial PACE (C-PACE)
Property Assessed Clean Energy financing for commercial properties funds energy improvements through a special assessment on the property, typically collected with property taxes.
- Pros: long terms that can match equipment life; often 100 percent financing; the obligation generally stays with the property when it sells; doesn't rely on the owner's corporate balance sheet in the same way.
- Cons: requires state enabling law and a local program; existing mortgage lenders usually must consent because the assessment can have priority; closing costs and program fees.
Residential PACE exists in a few states but has drawn significant consumer-protection scrutiny and regulation; treat it with care.
Ethical Selling and Consumer Protection
Solar has a reputation problem caused by a minority of sellers. Federal and state regulators — including attorneys general and consumer finance regulators — have pursued companies over misleading solar sales and financing. Rules for the job:
- No "free solar" and no implying the system is a government program.
- No guaranteed bill elimination. Savings depend on usage, the tariff, fixed charges, and weather.
- Disclose escalators, dealer fees, total payments, and term length in plain language.
- Don't promise tax credits. Describe them as conditional and refer customers to a tax professional.
- Base estimates on real usage and a production model, with assumptions (including any utility rate increase assumption) written down.
- Respect cancellation rights and never pressure a signature on a tablet the customer hasn't read.
- Check comprehension — especially with elderly customers or non-native speakers; provide documents in the language of the sale where required.
Going Deeper (Intermediate)
Compare options on the same page: upfront cost, monthly cost, total cost over the term, who owns the system, who gets incentives and SRECs, who maintains it, and what happens at home sale. A one-page comparison builds trust and filters out customers who'd regret the deal. Watch for double-paying: a customer whose loan payment plus remaining utility bill exceeds their old bill needs to know that before signing.
Advanced / Pro-Level
On commercial deals, financing choice shapes the whole project: a tax-equity-backed PPA, an operating lease, a direct purchase with depreciation, or C-PACE each changes the owner's cash flow, balance-sheet treatment, and risk. Pros model each with the client's finance team and accountant, account for incentive deadlines and documentation, and include degradation, O&M, inverter replacement, insurance, and roof replacement in the analysis. They also build compliance into the sales process — recorded welcome calls, written disclosures, and audits of sales claims.
Practice Challenge
A homeowner is offered a lease with a monthly payment slightly below their current average bill and an annual escalator, and plans to sell the house in three years. What should they understand? (Answer: they won't own the system or its incentives; the escalator means payments rise every year while utility rates may or may not keep pace; their remaining utility bill (fixed charges, unoffset usage) is added to the lease payment; and selling the house requires the buyer to assume the lease or a buyout, which can complicate the sale. Show total payments and transfer terms in writing.)
In Practice
Sales teams that lead with a clear comparison and honest assumptions get fewer cancellations and more referrals. The ones that lead with "free" spend their time on chargebacks.
Common Mistakes to Avoid
- Quoting a loan payment without disclosing dealer fees or the cash price
- Hiding the escalator in the fine print
- Ignoring how a lease or PPA affects a future home sale
- Promising tax credits or bill elimination
- Selling C-PACE without lender consent planned in
Takeaway: Cash, loans, leases, PPAs, and C-PACE each trade off ownership, cost, risk, and incentives — and the only sustainable way to sell any of them is with written, honest numbers the customer actually understands.
