The 5 Red Flags in a Solar Sales Pitch

The solar industry has a sales problem. For every honest installer doing good work, there is a company running door-to-door crews with high-pressure scripts, misleading savings projections, and contracts designed to confuse. The surge of installer bankruptcies over the past three years tells you how unsustainable some of these business models were.

Here are the five red flags that separate aggressive sales operations from legitimate solar companies — and what good companies do differently.

Red Flag 1: "This Price Is Only Good Today"

This is the oldest pressure tactic in sales, and solar companies use it constantly. A salesperson sits at your kitchen table, shows you a proposal, and tells you the price is a one-day special. Sign now or the deal disappears.

Why this is a red flag: Solar panel prices do not fluctuate day to day. Equipment costs are stable on a monthly or quarterly basis. Installation labor rates do not change overnight. There is no legitimate reason a price would be valid for only 24 hours.

What is really happening: The company wants to prevent you from getting competing quotes. They know that if you shop around, there is a good chance you will find a lower price — or discover that their proposal has issues.

What legitimate companies do: They give you a written proposal and encourage you to take your time. They know their pricing is competitive and that an informed customer is more likely to make a confident purchase. Good installers will tell you: "Take this home, compare it to other quotes, and call us when you are ready."

Red Flag 2: Savings Projections That Sound Too Good

"Your system will save you $80,000 over 25 years." "Solar will eliminate your electric bill completely." "You'll make money from day one."

These claims are technically possible in very specific scenarios. But when a salesperson leads with dramatic numbers without showing you the assumptions underneath, they are trying to sell you on an emotion rather than a financial reality.

Common tricks behind inflated projections:

Assuming electricity rate increases of 5–6% per year (the real average is 2.5–3%)
Projecting production as if your roof has perfect south-facing exposure with zero shading, when it does not
Claiming incentives that don't apply to your situation (e.g., leased systems can't claim the federal ITC; only owners can)
Not accounting for panel degradation (0.5% per year)
Calculating savings over 30 years when the equipment warranty is 25 years

What legitimate companies do: They show you the assumptions clearly. The utility rate escalation number is visible in the proposal. The production estimate is based on an actual assessment of your roof (satellite imagery or on-site survey). They tell you what the payback period is without sugar-coating it.

How to check: Run your own numbers using the PVWatts calculator from the National Renewable Energy Laboratory. Enter your address and system size — it gives you an independent production estimate. If the salesperson's number is more than 10–15% higher than PVWatts, ask them to explain the discrepancy.

Red Flag 3: Hidden Fees and Vague Contract Terms

You are quoted $25,000 for a system. Sounds reasonable. But buried in the financing terms is a dealer fee that adds 20–30% to the loan amount. Or the contract includes an annual escalator on your lease payment that is mentioned on page 8 in small print. Or the "25-year warranty" turns out to be a 25-year panel warranty, a 12-year inverter warranty, and a 5-year workmanship warranty.

Fees and terms to watch for:

Dealer fees on solar loans: These can add $3,000–$7,500 to your total cost. Ask: "What is the total loan amount compared to the cash price?"
Lease/PPA escalator clauses: A 2.9% annual escalator on a $140/month lease means you are paying $245/month by year 20. Ask: "What will my payment be in years 10, 15, and 20?"
Early termination fees: Some lease and PPA contracts charge $10,000–$20,000+ to exit early. Ask: "What does it cost to get out of this contract?"
Roof warranty gaps: The installation warranty (covering roof penetrations) may expire after 5–10 years, leaving you responsible if a panel mount causes a leak. Ask: "How long is the workmanship warranty on the roof penetrations specifically?"

What legitimate companies do: They walk you through the contract terms. They explain dealer fees upfront. They provide a clear warranty breakdown that lists panels, inverter, workmanship, and roof penetrations separately with specific durations.

Red Flag 4: Aggressive Door-to-Door Sales

A knock at your door from a young person in a branded polo shirt offering a "free solar assessment" is not inherently a scam. But the door-to-door solar model has produced a disproportionate number of consumer complaints, inflated pricing, and misleading claims.

Why the model is problematic:

Door-to-door reps typically earn commission only — sometimes $3,000–$5,000 per sale. This creates extreme incentive to close deals fast and move on.
Reps are often trained with scripts that emphasize urgency and emotion over accurate information.
Customer acquisition costs for door-to-door companies are much higher, which means higher system prices. You are paying for the army of salespeople knocking on your neighbors' doors.
High-pressure in-home appointments (sometimes lasting 2–3 hours) are designed to wear you down into signing.

What legitimate companies do: They market through their website, referrals, and platforms like EnergySage. They do not need to pressure you because they compete on price, quality, and reputation. Their salespeople are typically salaried or have a base salary, reducing the desperation to close every deal.

If a door-to-door rep visits: Take the proposal, say you need time to compare it with other quotes, and close the door. Do not let them pressure you into an immediate appointment or commitment. If they say the offer expires when they leave, that is your confirmation that you should not buy from them.

Skip the sales pressure — compare quotes on your own terms

EnergySage lets you request and compare quotes online from pre-vetted, highly-rated installers. No door-to-door reps, no kitchen-table pressure. You control the process.

Red Flag 5: The Lease Pitch That Hides the Downsides

Some solar companies lead with the lease or PPA option — "Go solar for $0 down! Lower your electric bill immediately!" — without clearly explaining what you are giving up.

What they downplay:

You do not own the system. The leasing company does. They get the tax benefits, incentive payments, and the long-term value of the equipment.
Lease escalators erode your savings. That "lower electric bill" in year 1 may not be lower by year 10 or 15 as escalator clauses push your payment up.
Home sale complications. The next buyer must assume your lease or you must buy it out. This has delayed and killed real estate transactions.
Total cost is often higher than buying. Over 25 years, leasing typically costs $15,000–$25,000 more than purchasing.
Early termination is expensive. Getting out of a lease early can cost $5,000–$20,000+.

What legitimate companies do: They present all options — purchase, loan, lease, PPA — with clear side-by-side comparisons. They explain the trade-offs honestly: zero down versus long-term savings, ownership versus convenience. They do not steer you toward the option that earns the company the most revenue.

The test: Ask the salesperson: "What would this system cost if I bought it outright?" and "Can you show me the 25-year total cost for the lease versus the purchase?" If they dodge, deflect, or do not have the numbers ready, they are selling you a lease because it benefits them, not you.

What Good Solar Companies Look Like

Trustworthy solar companies share common traits:

They encourage you to get multiple quotes. They are confident in their pricing and welcome comparison.
They provide detailed, transparent proposals. Equipment specs, production estimates with stated assumptions, warranty breakdowns, total cost including all fees.
They do not use high-pressure tactics. No "sign today" discounts, no manufactured urgency, no three-hour kitchen table sessions.
They have a track record. Five or more years in business, positive reviews on Google and the Better Business Bureau, verifiable installations in your area.
They are responsive after the sale. Good companies know that referrals from happy customers are their best marketing. They answer calls and handle warranty claims promptly.

Key Takeaways

"This price is only good today" = They do not want you to get competing quotes. Walk away.
Savings projections over $50,000 likely use inflated assumptions. Verify with PVWatts.
Hidden dealer fees can add 20–30% to your loan amount. Always compare the loan total to the cash price.
Door-to-door reps work on high commission, which drives higher prices and more pressure. Get quotes through transparent platforms instead.
Lease-first pitches often hide escalators, termination fees, and home sale complications. Always compare lease costs to purchase costs over the full contract term.
The best defense: get at least three quotes, compare them on price per watt, and never sign on the first visit.
