Most solar customers learn about Sunlight Financial from their installer’s tablet, not from a search engine. The installer pulls up a quote, taps through a few screens, and 30 seconds later you have a credit decision. That speed is what Sunlight sells. Here’s the machinery underneath it.
Step 1 — Your installer joins the Sunlight network
Sunlight Financial doesn’t lend directly to homeowners. It maintains a network of 15,000+ vetted solar installers and home-improvement contractors who use its proprietary platform, called Orange®. Joining the network requires the contractor to pass Sunlight’s underwriting for their business — financial health, install volume, complaint history — before they can offer Sunlight financing to customers.
Step 2 — You get a quote at your kitchen table
When you request a solar quote, the installer’s sales rep generates a system design (panel count, kilowatt size, estimated production) and a quote that includes both the cash price and the financed monthly payment. The financed monthly payment is calculated using one of Sunlight’s active loan programs, with the rate determined by:
- The dealer-fee tier the contractor has chosen for this customer
- Your credit tier, estimated from a soft pull
- The term length the contractor presents (usually the longest, because it shows the lowest monthly)
Step 3 — Instant credit decision in Orange®
You authorize the credit check. The installer enters your details into the Orange® portal. Within seconds, Sunlight returns one of three results: approved, conditionally approved (asking for additional documentation), or declined. The decision is driven by Sunlight’s underwriting model and the capital-provider rules behind the specific loan program your installer offered.
Step 4 — Loan documents and contract signing
If approved, you sign two documents: the installation contract with the contractor, and the loan agreement with the originating bank (currently Cross River Bank for indirect-channel loans). The loan agreement specifies the principal, APR, term, monthly payment, total interest, and the security interest (if it’s a secured loan).
Step 5 — Installation and milestone funding
The installer schedules your install. Sunlight typically funds the loan in two milestones: a partial advance at contract signing or panel delivery, and the balance at final inspection and Permission to Operate (PTO) from your utility. This protects you (the installer can’t take all the money up front) and the lender (no full disbursement until the system is operating).
Step 6 — Your loan moves to a capital provider
Behind the scenes, your loan is sold to one of Sunlight’s capital providers — typically a bank or institutional buyer. You may receive a notice that your loan servicing has transferred. The terms don’t change; only the entity collecting your payment does.
Step 7 — You start paying — and watch for the federal tax credit
Your first payment is due on the date specified in the loan agreement, usually 30–60 days after PTO. If your loan was structured as a re-amortizing loan tied to the federal solar Investment Tax Credit (ITC), applying that credit to your loan within the first 18 months will significantly reduce your monthly payment. Critical: the ITC is a tax credit, not a rebate — you have to owe enough federal tax to use it. Confirm with a CPA before assuming you’ll capture the full 30%.
Where this can go wrong
Most disputes we’ve seen from readers fall into one of four buckets:
- The promotional APR never applied. The salesperson quoted 0.99% but the loan documents show 4.99%. Read every signed document before scheduling installation.
- Dealer fees inflated the system price. The cash price is $24,000 but the financed price is $31,000 — that’s $7,000 of dealer fee buried in the principal.
- The tax credit didn’t materialize. A re-amortizing loan assumes you’ll apply ~30% of the principal as a lump-sum payment in year one. If you don’t, your payment jumps.
- The installer went out of business mid-project. Your loan obligation stays with you even if the system isn’t fully installed.
What to ask before you sign
- What is the cash price of this system, without financing?
- What is the dealer fee on this loan, in dollars?
- Is this a re-amortizing loan or a fixed-payment loan?
- What happens to my payment if I don’t apply the tax credit within 18 months?
- Who originates this loan, and who will service it long term?
If your installer can’t answer any of these clearly, ask for the loan documents in writing and read them at home. A reputable lender’s offer is still on the table next week.
