Financing is the single biggest barrier preventing homeowners from going solar—even when they're genuinely interested. Offering multiple payment pathways transforms tire-kickers into paying customers and positions you as the installer who actually solves problems instead of just quoting prices.
Why Financing Matters for Your Solar Business
Most residential solar installations run $15,000 to $25,000 before incentives. Even with a 30% federal tax credit, that's still $10,500 to $17,500 out of pocket for many customers. Without financing options, you're leaving 40–60% of qualified leads on the table. Contractors who present three to five financing paths close deals 2–3 times faster than those offering cash-only quotes.
The real win: financing customers typically commit faster, have higher satisfaction rates, and refer more friends. They've already made peace with the payment structure before you break ground.
Solar Loans: The Industry Standard
A dedicated solar loan is purpose-built for your customers and ranks as the most popular choice. These unsecured or secured loans typically carry 5–8% APR and 10–20 year terms, with monthly payments often matching or beating current electricity bills.
Key lender options include:
- Dedicated solar lenders (Sunlight Financial, GreenSky, Elevate) – specialized underwriting, faster approvals, integrated documentation
- Traditional banks (Wells Fargo, Bank of America) – competitive rates for strong-credit borrowers, but slower processing
- Credit unions – often lower rates for members, though smaller loan limits
- Manufacturer financing (Tesla, Enphase partnerships) – white-label programs with your branding
Partner with 2–3 lenders and learn their approval workflows. The lender that approves 70% of your applications in under 48 hours beats the one offering 0.5% lower rates but taking 10 days.
Home Equity Solutions: Higher Loan Amounts
Homeowners with substantial equity often qualify for HELOCs or home equity loans at rates 1–2% below solar-specific loans. Loan amounts range from $25,000 to $500,000+, making them ideal for larger installations or multi-property contracts.
The trade-off: longer application timelines (7–14 days) and appraisal requirements. Use these for customers who've already committed and aren't in a rush, or bundle them as a premium option for premium installations.
PPAs and Lease Models: Zero-Down Appeal
Power Purchase Agreements and solar leases shift the ownership structure—the solar company (or a third-party lessor) owns the system, and customers pay for the electricity it generates rather than the equipment itself.
This removes financing friction entirely and attracts budget-conscious customers. However, you'll either need to build your own lease-management infrastructure or partner with established lease servicers like Sunrun, Vivint Solar, or regional players. These partnerships typically take 4–8 weeks to set up and require commission splits of 5–15% of lease revenue.
Only pursue this route if you're installing 10+ systems monthly and have bandwidth for ongoing customer service.
PACE Financing: Municipal Programs
Property Assessed Clean Energy (PACE) programs attach financing to property taxes rather than personal credit. APRs typically range 4–7%, and repayment spreads across 15–25 years.
PACE works best for homeowners with fair credit (580–660 range) or older solar prospects. Drawbacks include limited availability by geography, longer approval windows (30–60 days), and potential resale friction. Check your state and county PACE administrator websites to confirm eligibility before promoting this option.
Structuring Your Financing Menu
Don't offer everything at once. Start with one solar lender relationship and add options as you close more deals. Your installer should be able to confidently explain:
- Monthly payment range for a typical 5 kW system
- Payback period (usually 5–8 years after incentives)
- Whether financing affects solar rebates or tax credits
- Application timeline and credit requirements
Post these specifics on your website and sales materials. Vague financing language signals that you're not serious about closing sales.
Getting Visibility for Your Services
Listing your financing options on Mercoly helps homeowners find you by comparing installation costs, available payment plans, and customer reviews all in one place—giving you a competitive edge against installers who only advertise cash pricing.
Frequently Asked Questions
Q: Can customers finance a solar installation if they have a mortgage? Yes—solar loans are typically unsecured and don't conflict with existing mortgages. HELOCs require sufficient equity, and PACE programs attach to property taxes, so all three work alongside mortgages.
Q: How does the 30% federal tax credit work with financed solar? The homeowner still claims the credit when filing taxes the following year, regardless of financing. They can either reduce their tax bill or (as of 2023) claim a refundable portion, so financing doesn't eliminate the incentive.
Q: Should I require a credit check before quoting? No—pre-screen with credit-soft inquiries only, then pull hard reports once the customer commits. Minimize credit pulls to avoid stacking hard inquiries, which lower credit scores.
