How to Choose a Solar Installer: A Complete Verification Checklist

Q: Can I trust door to door solar salespeople?

While some legitimate companies use door to door sales, this method is heavily favored by scammers. Never sign a contract on the spot and always verify their credentials independently.

Overview

Going solar is a massive financial decision, often costing tens of thousands of dollars. Unfortunately, the rapid growth of the solar industry has attracted bad actors looking to make a quick profit at the expense of homeowners. Knowing how to choose a solar installer and distinguish legitimate contractors from scammers is the single most important step in your solar journey. This guide provides a comprehensive checklist for verifying contractor credentials, comparing quotes, and avoiding predatory contracts.

Key Points

Always verify the installer’s state contractor license and look for NABCEP certification.
Check the Better Business Bureau (BBB) and Consumer Financial Protection Bureau (CFPB) for patterns of complaints.
Get at least three detailed quotes before signing any contract.

Contractor License Verification

Before you even entertain a quote, you must ensure the solar company is legally allowed to operate in your state. Unlicensed contractors often perform substandard work, leaving you with a system that doesn't pass inspection and voided roof warranties.

Every state has a licensing board (such as the CSLB in California). Visit your state’s contractor licensing portal and search for the company’s name or license number. Ensure the license is active, matches the company name exactly, and is approved for electrical or solar installations. If a salesperson says they "operate under a partner's license," demand to see the official partnership documentation.

The Importance of NABCEP Certification

The North American Board of Certified Energy Practitioners (NABCEP) is the gold standard for solar installation certifications. While a state license ensures legal compliance, NABCEP certification demonstrates specialized technical expertise.

Legitimate installers usually have at least one NABCEP-certified professional overseeing the design and installation of your system. Ask for their certification number and verify it on the official NABCEP website. Scammers rarely invest the time and money required to achieve and maintain this certification.

Consumer Protection Insight

Got Screwed on Solar? Don’t Let the Next Person Who Makes Money From Your Problem Be Your Lawyer.

The solar salesperson was paid. The installer was paid. The finance company drafts money from your account every month. And when you look for a solar lawyer, the conversation often turns to retainers, hourly rates, and money upfront.

Before paying a lawyer out of pocket, there is a critical question worth asking:

“Could any applicable law, based on your facts and jurisdiction, allow attorney fees to be sought from the other side?”

Asking you to pay is simple. Evaluating potential statutory fee-shifting under state UDAP laws, TILA, and deceptive trade practices requires investigating your actual contract and disclosures.

Checking BBB and CFPB Complaints

Don't rely solely on Google or Yelp reviews, as these can be easily manipulated or paid for by shady marketing teams. Instead, turn to the Better Business Bureau (BBB) and the Consumer Financial Protection Bureau (CFPB).

Search for the company on the BBB website. Look beyond the letter grade—read the actual complaints. Are there recurring issues with roof leaks, unfulfilled production promises, or aggressive sales tactics? Similarly, the CFPB database can reveal if a company (or their partnered lender) has a history of predatory financing practices, such as deceptive loan terms or hidden dealer fees.

Getting 3+ Quotes

One of the biggest mistakes homeowners make is signing a contract with the first salesperson who knocks on their door. Always get at least three competing quotes.

Legitimate installers welcome competition and will provide detailed proposals outlining the system size, panel brands, warranty terms, and total cash price versus financed price. If a salesperson uses high-pressure tactics ("this deal is only good for today"), show them the door. A reputable company will give you time to compare your options and consult with your family.

Red Flags in Installer Contracts

When reviewing a contract, watch out for these critical warning signs:

Missing itemization The contract should list the exact make and model of the panels and inverters.
Vague warranties Promises of a "25-year warranty" must be backed by written documentation explaining exactly what is covered (labor, parts, roof integrity).
Hidden dealer fees If financing, compare the cash price to the financed price. Scammers often hide massive "dealer fees" (sometimes up to 30%) in the loan principal.
Mechanic's liens clauses Understand what happens if the installer fails to pay their subcontractors.

FAQ

How do I know if a solar quote is reasonably priced?

A fair price typically ranges from $2.50 to $3.50 per watt (before incentives), depending on your region and equipment quality. If a quote is significantly lower or higher, treat it as a red flag.

Can I trust door-to-door solar salespeople?

While some legitimate companies use door-to-door sales, this method is heavily favored by scammers. Never sign a contract on the spot and always verify their credentials independently.

What should I do if an installer lies about their license?

Cease all communication immediately and report the company to your state's contractor licensing board and the Attorney General's office.

Standardized Case Preparation

Understand the Possibilities Before You Pay to Proceed.

The solar company has lawyers. The finance company has lawyers. You should have an opportunity to understand your own situation too—before assuming you must fund all legal costs yourself.

Question Fee-Shifting

Asking for a retainer is simple. But state UDAP laws, TILA § 130, and consumer statutes often allow attorney fees to be sought from the fraudulent company.

Build Your Evidence

Not how much is in your bank account, but what did they promise? What did you sign? Did your electric bill drop as promised? Where are the texts and proposals?

The solar salesperson may have been paid. The installer may have been paid. The finance company may be taking money from you every month. And now you have reason to believe something is seriously wrong.

So you Google: “Solar fraud lawyer.” And what happens next? You tell someone your story. They ask a few questions. And eventually, the conversation turns to: How are you going to pay for legal services? Retainer. Hourly rate. Money upfront.

Those arrangements may be appropriate in some matters. But before assuming that paying a lawyer is your only option, ask: “Could any applicable law, based on the facts and jurisdiction, allow attorney fees to be sought from the other side?”

The answer depends on the law, the contract, the claims available, the evidence, and the outcome. Asking you to pay is simple. Evaluating potential fee-shifting requires investigating your contract, financing terms, utility bills, texts, cancellation attempts, and consumer-protection statutes.
