Solar Sales Traps: 9 Tactics and How to Spot Them

Solar is a good product sold, too often, by bad process. The industry’s door-to-door and lead-gen channels are paid on signature, not on your 25-year satisfaction, and state attorneys general and the FTC have spent years warning about the same patterns. None of the nine tactics below requires the salesperson to lie outright — most work by rushing you past the one number or clause that matters. Each entry gives you the tell and the counter-question. Print this page before your next “free solar assessment.”

1. “The panels are free”

The pitch: a government programme will put panels on your roof at no cost. The reality: there is no such programme for typical homeowners. “Free” almost always means a lease or power purchase agreement (PPA) in which a company owns panels on your roof and sells you the power for 20–25 years — sometimes fairly priced, often not, and never free. Ask: “Who owns the system, who claims any incentives, and what is my total payment over the full term?” Then compare that total with a cash purchase from our Payback Calculator.

2. The phantom tax credit

The pitch: “The government pays 30% — but the programme is ending, sign now.” The reality: this was the standard close for a decade, and it is now doubly wrong: federal rules changed after 2025 and the 30% residential credit is no longer available for new homeowner installations. A 2026 quote with a 30% federal credit line is using expired maths — and any “your cost after credit” figure built on it is fiction. Ask: “Show me the current IRS page for that credit.” Watch the meeting end. Verify what still exists on our incentives page.

3. Production promises 30% too high

The pitch: a glossy estimate showing your 8 kW system producing 15,000 kWh a year in a 4.3-sun-hour state. The reality: honest production = kW × sun hours × 365 × a performance factor of about 0.78–0.85. Inflated quotes quietly use 0.95+, assume a perfect south roof, or model your partial shade as full sun. Ask: “What production factor and sun-hour figure did you use?” — then check the same system in our Size Estimator, which shows its working.

4. The vanishing bill

The pitch: “Your new electric bill: $0.” The reality: fixed connection charges, minimum bills and non-bypassable per-kWh charges survive any system size, and under net billing your exports don’t offset imports one-for-one. A realistic best case is an 80–95% reduction in the variable part of the bill. Ask: “Which charges remain in month one — show me a sample bill for an existing customer in my utility.”

5. The escalator lease

The pitch: a lease or PPA payment that starts temptingly below your current bill. The reality: many contracts raise that payment 2.9–3.5% every year for 25 years. Utility prices might rise slower — in which case your “savings” invert in the back half of the contract, precisely when you’re locked in and selling the house means negotiating a transfer with a buyer. Ask: “What is the escalator, and what is the total of all 300 payments?” Then compare against utility escalation of 3% and of 1.5%.

6. Dealer-fee financing (“same price, easy payments”)

The pitch: a low-interest loan with no money down, quoted at the same system price as cash. The reality: solar loans commonly carry dealer fees of 15–30% baked into the principal — the “cash price” magically grows, or the interest rate is bought down with your own money. Two quotes for the same roof can differ by $8,000 purely in financing structure. Ask: “What is the cash price, in writing, and what is the total of payments including all fees?” Compare loans on total cost, never on the monthly figure.

7. The 40-year roof and the 25-year roof problem

The pitch: panels that “last 40 years” installed on your 18-year-old shingles today. The reality: panels are warranted ~25 years; if your roof needs replacing mid-life you’ll pay $1,500–$3,000 to remove and reinstall the array. Enthusiastic sellers minimise roof age because re-roofing first delays their commission. Ask: “How many years of life does my roof covering have, and who pays for removal if it fails early?” Our roof guide covers the sequencing.

8. Pressure with a deadline

The pitch: “This price is only good tonight / the programme closes Friday / your neighbour just signed.” The reality: legitimate incentives have published rules and dates; legitimate installers leave written quotes valid for days or weeks. Manufactured urgency exists to prevent exactly one thing: you getting two competing quotes and running your own numbers. Rule: never sign a 25-year contract at a kitchen table on day one. Any deal that can’t survive 48 hours of scrutiny isn’t a deal.

9. The disappearing company

The pitch: a slick brand, a local-sounding name, a 25-year workmanship warranty. The reality: solar has high installer churn; the warranty is worth the company’s lifespan. Subcontracted installation crews, rented offices and a sales org with no service department are the pattern. Ask: “How long have you installed under this licence, who services warranty claims, and can I speak to three customers from two years ago?” Check the state contractor licence and complaint history — it takes ten minutes and filters out most of the risk.

The five-number defence

Every tactic above dissolves when you anchor on five numbers you compute yourself: your real kWh usage, your state’s honest production per kW, a fair price per watt (≈$2.50–$3.10 in 2025), your utility’s export percentage, and the total contract cost including escalators and fees. Sales scripts are built to keep the conversation on monthly payments and monthly “savings.” Drag it back to totals and unit prices, on paper, and you become a very difficult customer — which is to say, a well-served one.
