Loan Payments That Start Before the System Runs
Your first payment won't be due for a while, and by then your system will be up and running and covering it.
What's actually true
Many solar loans start when the lender pays the installer, which can be at installation, long before the utility grants Permission to Operate. During that gap, you pay both the loan and your full utility bill.
With many solar loans, your clock starts when the lender pays the installer, not when your panels start making power. If that happens at installation, and Permission to Operate (PTO) takes months, you’ll pay a loan for a system that’s legally switched off while still paying your full electric bill. Complaints about loan payments starting before the system worked show up repeatedly in our research on lenders and failed installers, including GoodLeap and Freedom Forever customers.
Why it happens
Installers want to be paid as early as possible. Point-of-sale solar lenders often release money in stages, with a large share at installation. Once the installer is paid, the loan is “funded,” and interest and payment schedules can begin. The installer has less reason to hurry through inspection and PTO after that, and if the installer goes out of business, you can be left with a funded loan and an unfinished system.
A worked example
Take a $30,000 loan at 3.99% for 25 years, about $158 a month. Your 8 kW system would save roughly $160 a month once running (at the U.S. average of about 18.3¢/kWh, EIA July 2026; your rate and production will differ).
| Month 1-4 (installed, no PTO) | After PTO | |
|---|---|---|
| Loan payment | $158 | $158 |
| Electric bill | Full bill, say $180 | Reduced |
| Solar savings | $0 | about $160 |
Four months of waiting means about $632 in loan payments with zero solar savings. If PTO takes longer, or the installer disappears before finishing, that number keeps growing.
Watch out: Interest may begin accruing at funding even if your first payment is due later. A “no payments for 90 days” promise doesn’t always mean “no interest for 90 days.”
How it shows up in the paperwork
- Loan agreement: “Interest accrues from the date of disbursement,” or a first payment date tied to “funding” or “installation.”
- Completion certificate: a form or phone call from the lender asking you to confirm the work is done so they can pay the installer. This is your leverage. Once you confirm, it’s gone.
- Installation contract: a payment schedule with most of the money due at installation and little or nothing held back for PTO.
- Reamortization terms: older loans assumed you’d pay down a big chunk (the old federal tax credit) by month 18 or so. In 2026 there is no homeowner credit, so check how the payment is calculated. See reamortization balloon.
Questions to ask
- “On what date does interest start? On what date is my first payment due?”
- “Is the first payment tied to PTO, or to installation or funding?”
- “How much of the money does the lender release at installation, and how much at PTO?”
- “Will the lender ask me to sign a completion certificate? When?”
- “If PTO takes six months, what do I pay in the meantime?”
How to protect yourself
- Don’t sign off early. Only confirm completion when the system is installed, passed inspection and has PTO, and you’ve seen it produce power.
- Negotiate a holdback. Ask that a meaningful final payment be due only at PTO.
- Consider your own financing. A HELOC (about 7.34% national average as of October 2026, per Bankrate) or a credit union loan lets you pay the installer on your schedule, and avoids dealer fees. Compare with the solar loan calculator and dealer fee calculator.

Where to report
If a lender started billing for a system that was never completed, or funded the installer based on a completion you didn’t approve, file a complaint with the CFPB and your state attorney general. Report unfinished work to your state contractor licensing board.

Fast-Start Promises and Months of PTO Delays
A solar system can't legally run until the local permit is approved, it passes inspection, and the utility grants Permission to Operate (PTO). That process can take weeks to months, depending on your city, utility and HOA, and the installer doesn't control most of it.
Hidden Dealer Fees Behind "Low APR" Solar Loans
Low-rate solar loans are usually paid for by a dealer fee the lender charges the installer, which is added to your price. The CFPB says these fees typically run 10% to 30% of the cash price and sometimes exceed 50%.
The Month-18 Payment Jump (Reamortization)
The low payment is often calculated as if you will pay down about 30% of the loan early. If you don't, the loan re-amortizes and the payment can jump by 40% or more. Homeowners who buy in 2026 get no federal credit to make that paydown.
Installer Bankruptcy Risk Brushed Aside
Several of the largest U.S. solar installers and lenders filed for bankruptcy between 2024 and 2026. When an installer disappears, its workmanship and roof warranties usually disappear too, but your loan or lease payments do not.
