Quick answer: Choose a solar installer by checking that your utility or regulator approves them, getting three itemized quotes, comparing price per kW and warranties, and reading the contract at home. Walk away from anyone who pushes a same-day deal, promises zero bills, or won’t show the cash price. A good installer lets you take your time.
Knowing how to choose a solar installer matters more than picking between panel brands. A rooftop system runs for 25 years or more, and the crew that wires it and the contract you sign decide how well it performs.
Pressure tactics aren’t limited to one country. pv magazine’s homeowner guide notes that cold callers and door-to-door sellers often lead with urgent deals. This guide gives you a vetting checklist, a way to compare quotes fairly, and the exact lines to use when a salesperson leans on you.
What do pushy solar sales tactics look like?
They all try to make you decide before you can compare. Here are the patterns that come up most often, and what to do about each one.
| Tactic | What you’ll hear | What to do |
|---|---|---|
| Fake deadline | “This price ends today.” “Act now to lock the rate.” | Ask for the quote in writing and decide later. NPR reporting describes urgency as a common sales tactic. |
| Vanishing tax credit (US) | “The 30% credit is ending, sign now.” | The homeowner credit (Section 25D) ended on December 31, 2025, so don’t let anyone subtract it from a 2026 price. See Solar.com’s summary. |
| Zero-bill promise | “You’ll never pay for electricity again.” | Ask for the assumptions behind the savings. An Australian consumer guide calls “eliminate your bills” lines a warning sign, because panels rarely cancel a bill all year (SolarCalculator.com.au). |
| Posing as the utility | “I’m here on behalf of your electricity company.” | Ask for ID, then call your utility on its official number. NPR notes that door-to-door reps sometimes claim to be with the local utility. |
| Sales-only middleman | A friendly rep who never mentions who does the work. | Ask who installs the system and who holds the license. Many sales companies subcontract the installation. |
| “No money down” | “0% interest, nothing to pay today.” | Ask for the cash price. The financed price can hide extra fees (more on that below). |
A simple rule of thumb: did you go looking for solar, or did the salesperson find you? If they found you, treat the offer as unsolicited and slow everything down. Most experts quoted by NPR suggest working directly with an installation company rather than a sales-only firm.
How do you check that a solar installer is legitimate?
Confirm their approval with the body that controls grid connection or consumer protection in your market. In many Gulf cities and in the UK, an unapproved installer can leave you without a legal grid connection or without export payments.
Ask for the company’s license or approval number, then check it yourself on the official list. Don’t rely on a PDF the salesperson sends. Also look for a real physical address and an established track record, which pv magazine’s sources recommend.
| Market | Check this | Good to know (as of October 31, 2026) |
|---|---|---|
| Dubai, UAE | DEWA Shams Dubai approved consultant or contractor | Only enrolled firms can submit applications, and the list is on DEWA’s website. Exports are credited against future bills, not paid in cash, per this 2026 regulatory guide. |
| Abu Dhabi, UAE | ADDC-approved contractor under the Department of Energy framework | Abu Dhabi has extended its solar self-supply policy to villas for the first time, so confirm the current rules before signing (Lexis Middle East). |
| Sharjah, UAE | SEWA enrollment | A DEWA approval doesn’t transfer to SEWA. Ask which utility the firm is enrolled with for your address (SurgePV). |
| Saudi Arabia | Contractor qualified by the regulator, plus a connection agreement with the Saudi Electricity Company | Net metering rules took effect on July 1, 2018 for systems from 1 kW to 2 MW (Enerdata). On October 20, 2026, the regulator was reported to have proposed a new net billing framework, so rules may shift. |
| Bahrain | EWA-approved distributed renewable contractor | One 2026 guide describes residential net metering up to 100 kW, with credits instead of cash (SurgePV). |
| Qatar and Kuwait | Utility approval for any grid connection | A 2026 regional guide lists no retail net metering program in either country. Treat any “export income” claim with extra suspicion. |
| Oman | Authority for Electricity Regulation (AER) rules | Oman has run its own Sahim rooftop scheme, which a 2021 legal briefing describes as a feed-in tariff. Terms may have changed, so confirm with the regulator. |
| United Kingdom | MCS-certified installer, plus membership of a consumer code (RECC, HIES or GGF) | Smart Export Guarantee payments almost always require an MCS certificate (Reonic, 2026). Ask for the certificate number after installation. |
| United States | State or local contractor license and proof of insurance | NABCEP certification is a voluntary extra, not a replacement for a license. Nonprofit Solar United Neighbors, active in 11 states, Puerto Rico and Washington, D.C. as of 2024, publishes questions to ask installers. |
Approval lists change. One 2025 regulatory guide counted 111 certified contractor companies on DEWA’s list, and another notes that the registry needs annual renewal. Check the live list on the day you sign.
How do you compare solar quotes fairly?
Get three itemized quotes and divide each total by the system size in kW. The price per kW shows you which quote is an outlier. Then ask why.
Here’s an illustration with made-up numbers for an 8 kW villa system. The exchange rate is the UAE dirham peg of 3.6725 per US dollar.
| Quote | Total | Price per kW | Question to ask |
|---|---|---|---|
| A | AED 36,000 (about $9,803) | AED 4,500 (about $1,225) | What brands and warranties are included? |
| B | AED 29,000 (about $7,897) | AED 3,625 (about $987) | Why 19% cheaper than A? Which parts or fees are missing? |
| C | AED 52,000 (about $14,159) | AED 6,500 (about $1,770) | What justifies 44% more than A? |
The cheapest quote isn’t automatically the best, and the dearest isn’t automatically the safest. A very low price can signal weaker equipment or shortcuts, a point CertainTeed’s installer guide makes too. Your job is to make the three quotes comparable.
Every quote should state:
- Panel and inverter brand and model, with datasheets.
- System size in kW and the estimated yearly output in kWh, with the assumptions behind it.
- All utility or regulator fees and who pays them. Anyone who skips this is hiding something.
- Separate warranty lengths for equipment and for workmanship. CertainTeed’s guide notes that some companies offer no workmanship warranty at all.
- A payment schedule tied to milestones, not a large deposit on day one.
- Who handles approvals and paperwork. pv magazine’s sources say the installer should take charge of these.
Which savings and financing claims should you question?
Payback promises
Published payback figures for the same type of Dubai villa vary wildly. Property Finder cites roughly 3 to 6 years, a Voltflow guide says 5 to 8 years, and a developer’s guide claims 7 to 10 years. Prices vary too: Property Finder’s 2026 guide puts a 5 kW villa installation at AED 20,000 to 30,000 (about $5,450 to $8,150), while other guides run lower and higher.
That spread is your cue to do the math with your own bill. Payback in years is the system price divided by the yearly savings. With a hypothetical AED 36,000 system saving AED 5,000 a year, payback is 7.2 years. A salesperson promising 3 years on that system is claiming AED 12,000 in yearly savings. Ask to see the calculation on your actual consumption.
“Free” and “no money down” offers
Zero-down offers exist, but you still pay through a loan, a lease or a power purchase agreement. In the US, the Consumer Financial Protection Bureau reported in August 2024 that lender “dealer fees” often raise a solar loan’s cost by 30% or more above the cash price, and the fees are frequently left out of the stated APR.
Picture a hypothetical $20,000 cash price with a $26,000 loan principal. That $6,000 gap is a 30% markup, and it needs a clear explanation. The CFPB’s advice is to ask for the cash price, get a financing quote from a bank or credit union, and compare several proposals.
Tax credits and export income
State the year when anyone quotes you an incentive. In the US, the 30% credit for homeowner-owned systems is gone for installs completed after December 31, 2025. Third-party-owned systems (leases and power purchase agreements) can still earn a business credit for the owner, but the rules are tightening, so get the terms in writing (NRG Clean Power).
In the Gulf, ask exactly how exports are compensated. Dubai and Bahrain credit exports against future bills, Saudi Arabia’s rules are being revised, and Qatar and Kuwait have no retail net metering program according to the 2026 regional guide above. “You’ll earn money from the grid” isn’t a safe assumption anywhere in the region.
What should you ask about heat, dust and maintenance in the Gulf?
Ask whether the yield estimate accounts for heat and dust. Panels lose output as they get hot, and a Voltflow guide points out that output per kW can be lower in summer than in spring or autumn despite longer days. It also names dust as a significant factor.
Four questions to put to every installer:
- Heat: What is the temperature coefficient on the panel datasheet, and is it in the yield estimate?
- Dust: Who cleans the panels, how often, and what does it cost? One UAE guide puts typical villa system maintenance at AED 600 to 1,000 a year (about $163 to $272), but get your own number.
- Roof: Who confirms the roof can take the extra weight? One 2026 guide says buildings over 15 years old typically need a structural assessment.
- Equipment: Are the panels and inverter on your utility’s approved lists? DEWA’s standards, for example, require approved module and inverter lists.
What do you say when a salesperson pushes?
Short, calm lines work best. You don’t owe a long explanation.
- “Send me the quote by email. I’ll decide after I’ve compared three.”
- “What’s the cash price, and what’s included in it?”
- “Which company installs, and what’s their license or approval number?”
- “If this price is real today, it should be real on Monday. I’m not signing today.”
If the person keeps pushing, that’s your answer about the company. A reputable installer, as CertainTeed puts it, gives you the information and the time to decide.
Can you cancel after signing?
It depends on where you live and where you signed. In the US, the FTC’s Cooling-Off Rule gives you three business days to cancel certain sales of $25 or more made at your home or another location away from the seller’s permanent place of business. The seller must tell you about this right (FTC, Arizona Attorney General). The rule doesn’t cover every transaction, and states can add their own rights. Outside the US, check your local consumer-protection law before you sign, and don’t assume a cooling-off period exists.
Green flags and red flags at a glance
| Green flags | Red flags |
|---|---|
| Appears on the official approved-contractor list | Can’t or won’t give a license or approval number |
| Itemized quote with brands, models and warranties | One-line price with no equipment details |
| Shows the savings math on your own bill | Promises zero bills or a fixed payback with no calculation |
| Happy for you to compare and take a week | “Today only” pricing or a push to sign on a tablet |
| Real address, local references, after-sales support | No physical address, or the salesperson isn’t from the installing company |
Take your time with this decision. Verify the approval, compare three itemized quotes on price per kW, and sign only what you’ve read at home.
Frequently asked questions
How many solar quotes should I get?
Get at least three. Multiple quotes are standard advice from installers and consumer guides, and three gives you enough to spot an outlier on price per kW.
Is it safe to sign a solar contract on the spot?
No. Good installers don’t need an on-the-spot signature. Take the contract home, read every clause, and compare it against other quotes first.
How do I know a solar installer is licensed?
Check the official list for your market: DEWA for Dubai, EWA for Bahrain, MCS for the UK, or your state license board in the US. Ask for the license or approval number and verify it yourself.
Are “free solar” or zero-down offers real?
You still pay, through a loan, lease or power purchase agreement. Ask for the cash price and compare it with the financed total, because fees can inflate the loan principal.
Can I cancel a solar contract after signing?
In the US, certain home sales carry a three-business-day right to cancel under the FTC’s Cooling-Off Rule, and some states add more. Elsewhere, check local consumer law before signing.
