12 Solar Contract
Red Flags to Know Before You Sign.
And what to do if you already did.

An escalator clause automatically increases your loan payment by a fixed percentage every year — most commonly 2.9% annually. On a $40,000 loan, this turns a $250/month starting payment into $390/month by Year 20. The total additional cost over 25 years frequently exceeds $18,000. This clause is buried in schedule exhibits or addenda and rarely mentioned verbally during sales.

Solar lenders pay installers a "dealer fee" — essentially a commission funded by inflating your loan amount. A $28,000 installation might be financed at $40,000 with the $12,000 difference paid to the installer as a lender commission. You never see this on your contract. The consumer-facing documents show only the total loan amount, never the breakdown. This is the most common source of solar fraud in 2024–2026.

Most solar lenders file a UCC-1 financing statement against your property to secure the loan. This creates a lien on the solar equipment — and sometimes on the property itself as a fixture filing. The critical problem: when you go to sell or refinance your home, this lien appears in title searches. Many sales have been delayed or blocked because buyers' lenders refuse to accept the lien. Payoff demands can be aggressive and the lender's consent is required for clear title.

The 30% federal Investment Tax Credit (ITC) is frequently misrepresented during the sales process. Common misrepresentations: (1) the ITC being described as a "rebate" or "refund" when it is only a non-refundable tax credit; (2) loans being structured assuming you'll use your ITC to pay down principal — and dramatically increasing your payment in Year 2 when you don't; (3) the credit being guaranteed regardless of your tax liability. If you don't owe federal taxes, you may receive little or no credit at all.

PACE (Property Assessed Clean Energy) loans are fundamentally different from standard solar loans. They are repaid through your property tax bill and create a lien that is senior to your mortgage. This means the PACE lien gets paid before your mortgage lender in the event of foreclosure. Most homeowners are not told this. Many find out only when they try to sell or refinance — at which point their mortgage lender demands the PACE lien be paid off in full before they will proceed. Common PACE lenders: Ygrene, HERO (legacy), Renew Financial, Lyon Financial.

The Truth in Lending Act (TILA) requires lenders to clearly disclose the Annual Percentage Rate (APR), total finance charge, payment schedule, and total amount financed. Solar loan TILA violations include: failure to disclose the escalator clause as part of the APR calculation, missing or incorrect total payment disclosures, and inadequate disclosure of variable rate structures. TILA violations can give borrowers a right of rescission and potentially void the loan contract.

Some solar loans include prepayment penalties — fees charged if you pay off the loan early. These are typically found in contracts signed before 2022 and can represent a significant percentage of the remaining principal. Homeowners who receive a cash settlement, sell the home, or come into money and want to pay off the solar loan are often surprised to find an additional 1–5% payoff penalty that was not discussed at signing.

Solar installers often provide savings projections showing dramatic lifetime electricity savings. These projections are frequently overstated — sometimes by 200–300%. Red flags: projections that assume flat or rising utility rates for 25 years without accounting for efficiency degradation, shading changes, or net metering policy changes. SAS forensic audits compare stated projections against actual system specs, roof orientation, local utility data, and production history.

In documented GreenSky and several other lender cases, loan funds were drawn by the contractor without full homeowner authorization. The contractor receives payment before the installation is complete or before the homeowner signs a final completion certificate. The homeowner is then bound to the full loan — even if installation was incomplete, defective, or never finished. This is particularly common in markets with high-pressure door-to-door sales and quick-turn installations.

Solar sales representatives frequently make verbal promises that never appear in the written contract — and which directly contradict it. Common examples: "Your bill will be zero," "We'll take care of the HOA approval," "This roof is guaranteed for 25 years," "If you're not saving money we'll buy it back." If you made your decision based on verbal representations that differ from what your contract actually says, you may have claims for fraudulent inducement or misrepresentation depending on your state.

In communities governed by HOAs or with strict permitting requirements, installers sometimes proceed with installation without obtaining required approvals. The homeowner then faces HOA fines, mandatory removal orders, and potential legal liability — while still being bound to the solar loan. Some installers falsely represent that they will handle all approvals, or that approvals are not required, in order to close the sale quickly.

Your solar loan agreement, installer proposal, or performance guarantee may specify a minimum annual energy production figure. If your system consistently produces materially less than that figure — and you can demonstrate this with monitoring data — you may have a performance guarantee claim against the installer and potentially the lender. Underperformance below the contract threshold triggers warranty obligations that installers and lenders frequently refuse to honor without legal pressure.
