12 Solar Power Scams Homeowners Should Know About (& How to Avoid Them)

While residential solar power systems have become a much more common sight in the last few years, there’s also something else homeowners are encountering. Unfortunately, the growing popularity of residential solar has also led to an increase in solar power scams.

Many residential property owners have reported scams ranging from misleading sales pitches and aggressive door-to-door tactics to hidden fees, inflated savings estimates, and contracts that don’t tell the whole story.

If you’re considering installing a home solar system, not to worry: most solar scams follow familiar patterns. Knowing what to look for can help you ask better questions, avoid costly mistakes, and move forward with confidence.

 

The Top 12 Most-Common Solar Power Scams Homeowners Face 

Most solar companies work hard to earn their customers’ trust. Unfortunately, a handful of dishonest companies have given the industry a black eye of sorts by relying on misleading advertising, aggressive sales tactics, and confusing contracts. 

Here are some of the most common solar power scams homeowners should know about before making a decision to sign with any solar company:

1. Misleading “free solar” offers
2. Claims that programs are “government approved” 
3. Inflated estimates of federal, state, and local tax incentives
4. Fake utility company representatives
5. Exaggerated energy savings projections
6. Promises that solar panels will completely eliminate electric bills
7. Leasing agreements disguised as ownership arrangements
8. Hidden financing fees, escalator clauses, and long-term contracts
9. Unlicensed or uninsured installers
10. Companies that use subcontractors without informing the homeowner
11. Poor-quality equipment presented as premium products
12. Companies claiming an existing system has failed to sell unnecessary repairs

 

1. Misleading “Free Solar” Offers

“Free solar” is one of the most common phrases used in solar advertising, but homeowners should approach the claim carefully. 

In some cases, companies are referring to lease agreements or power purchase agreements (PPAs), not systems that the homeowner actually owns. In others, the term is simply being used to attract attention, even though financing costs, installation fees, and long-term contractual obligations still apply.

That’s not to say every company using the phrase is operating dishonestly. However, if someone tells you that solar is completely free, it’s worth taking a closer look at exactly what they’re offering.

How to Avoid This Scam: Ask whether you’ll own the system outright, lease it, or enter into a power purchase agreement. Request a written breakdown of all costs, fees, financing terms, and maintenance responsibilities before signing anything. If the details seem unclear, walk away until you have answers.

 

2. Claims That Programs Are “Government Approved”

Some companies try to build credibility by suggesting that their products, financing plans, or installation programs have been endorsed by a federal, state, or local government agency. Others may imply that homeowners have been specially selected to participate in a limited-time program. While tax credits, rebates, and other incentives certainly exist, that doesn’t mean the company itself has received government approval.

This tactic is especially common in a door-knocking solar scam, where a salesperson may present official-looking documents or use language intended to create a sense of urgency.

How to Avoid This Scam: Ask for the name of the program and verify the information yourself. A reputable installer should be willing to explain available incentives without exaggerating them or creating unnecessary pressure.

 

3. Inflated Estimates of Federal, State, and Local Tax Incentives

Tax credits and incentives can significantly reduce the cost of installing a solar energy system, but some companies present those savings in misleading ways. Even though eligibility depends on a homeowner’s specific circumstances, in some scams incentives are: 

• Overstated
• Falsely combined 
• Treated as guaranteed

Unfortunately, this type of residential solar scam can leave homeowners with unexpected costs and unrealistic expectations about the true price of a system and its ROI.

How to Avoid This Scam: Ask the installer to separate equipment costs, labor costs, financing costs, and available incentives into individual line items. You should also consult a qualified tax professional if you have questions about eligibility requirements.

 

4. Fake Utility Company Representatives

One of the more deceptive solar scams involves salespeople claiming to work for, or alongside, a utility company. They may request copies of recent electric bills, insist that new regulations are about to take effect, or imply that homeowners are required to install solar panels to maintain service.

In reality, utility companies rarely conduct business this way, and homeowners should be cautious whenever someone shows up unannounced and asks for personal information.

How to Avoid This Scam: Never assume that someone at your door represents your utility company simply because they’re wearing a uniform or carrying identification. Contact the utility directly if you have questions, and avoid sharing account information until you’ve confirmed who you’re dealing with.

 

5. Exaggerated Energy Savings Projections

It’s no secret that solar can reduce electricity costs substantially. Exact savings, however, vary depending on: 

• Location
• Roof condition
• Energy use
• Utility rates
• Weather patterns
• System size 

Some scammers rely on overly optimistic assumptions to make their proposals appear more attractive.

Promises of dramatic savings may sound appealing, but projections should always be based on actual data rather than best-case scenarios.

How to Avoid This Scam: Ask to see the assumptions behind the estimate. A reputable installer should be able to explain how projected savings were calculated and what factors could affect them over time.

 

6. The Elimination of Electric Bills

This claim is closely related to exaggerated savings estimates, but it deserves special attention because it remains one of the most persistent solar scams in the industry. Even homeowners with large systems may still receive utility bills because of service charges, seasonal fluctuations, changing energy consumption, and local net metering rules.

Put simply: lower utility bills are common, but eliminating them entirely isn’t always realistic.

How to Avoid This Scam: Ask your installer for a realistic range of potential savings rather than a guaranteed number and ask for those numbers in writing. Be especially cautious if someone promises that your electric bill will disappear forever.

 

7. Leasing Agreements Disguised as Ownership Arrangements

Not every homeowner wants to purchase a solar energy system outright. Leasing can be a good option in some situations, but problems arise when a solar lease scam makes it difficult for homeowners to understand exactly what they’re signing.

Ownership, maintenance responsibilities, warranty coverage, financing terms, and future home sales can all be affected by the details of the agreement.

How to Avoid This Scam: Read every document carefully and ask direct questions about ownership, monthly payments, maintenance obligations, and transfer requirements if you decide to sell your home. Never rely solely on verbal promises.

 

8. Hidden Financing Fees, Escalator Clauses, and Long-Term Contracts

Solar financing agreements can span decades. That means even small details can have a significant impact over time. Some contracts contain annual price increases, penalties for early termination, or fees that aren’t clearly explained during the sales process.

These costs may not become apparent until long after the installation is complete.

How to Avoid This Scam: Review the contract carefully before signing and ask for clarification whenever something seems unclear. Taking a day or two to review the paperwork could save you thousands of dollars in the long run.

 

9. Unlicensed or Uninsured Installers

Solar installation is highly specialized work that involves roofing, electrical systems, permitting requirements, and local building codes. Hiring an installer who lacks the proper qualifications can create safety risks and lead to expensive repairs.

In some cases, homeowners don’t discover the problem until they need service or file an insurance claim.

How to Avoid This Scam: Verify that the company is properly licensed, insured, and qualified to perform the work in your area. A reputable installer should be happy to provide documentation.

 

10. Companies That Use Subcontractors Without Informing the Homeowner

Many solar companies work with subcontractors, and there’s nothing inherently wrong with that arrangement. Problems arise when homeowners believe they’re hiring one company, only to discover later that much of the work has been handed off to someone else.

Miscommunication can lead to delays, confusion, and uncertainty about who is responsible for future service.

How to Avoid This Scam: Ask who will perform the installation and whether subcontractors will be involved. Make sure you understand who is responsible for the workmanship warranty and any future maintenance needs.

 

11. Poor-Quality Equipment Presented as Premium Products

Not all solar panels, inverters, batteries, and mounting systems are created equal. Some companies advertise premium equipment while installing lower-quality alternatives that may not perform as expected.

This can affect everything from energy production and efficiency to reliability and long-term durability.

How to Avoid This Scam: Ask for the manufacturer, model numbers, warranty information, and performance specifications for every major component. Taking a little time to research the equipment can help you make a much more informed decision.

 

12. False Claims an Existing System Has Failed

This scam has become increasingly common as more homeowners install solar systems and more installers enter the market. In some cases, homeowners are told that their equipment has failed, become obsolete, or needs to be replaced immediately when a much simpler repair or servicing would solve the problem.

This can be especially frustrating for people whose original installer has gone out of business.

How to Avoid This Scam: If someone recommends a major repair or replacement, seek a second opinion. An experienced service provider should be able to identify the source of the problem and explain why a particular solution is necessary.

 

The #1 Way to Avoid Being Scammed

There’s no way to eliminate risk entirely, but there is one thing homeowners can do to dramatically reduce the chances of running into trouble: work with a reputable local installer.

A trustworthy solar company should be willing to answer questions, explain its recommendations, provide references, discuss financing options openly, and give you time to make a decision. If someone is pressuring you to sign a contract immediately, refusing to provide information in writing, or making promises that seem too good to be true, those are signs that you should proceed with caution.

It’s helpful to:

• Get multiple quotes
• Verify licenses and insurance coverage
• Read reviews
• Ask exactly who will be performing the work
• Get as much as you can in writing

A little extra research on the front end can help protect your investment for years to come.

 

An Informed Homeowner Is a Protected Homeowner

Solar can be an excellent investment, but like any major purchase, it’s important to do your homework before signing on the dotted line. 

Taking a little extra time to research installers, review contracts, and ask questions can go a long way toward helping you avoid common solar power scams.
