8 Common Mistakes When Hiring a Solar Installer in Texas (and How to Avoid Them)
Installing solar panels is one of the most profitable home improvements a Texas homeowner can make — but it’s also a decision you typically make once every 25 years. A mistake in the buying process isn’t easy to fix afterward: it usually involves a long-term contract, a physical system installed on your roof, and in many cases, financing you’re committed to for years.
After reviewing consumer complaints, consumer advocate recommendations, and specialized guides, here are the mistakes that come up most often — and how to avoid them.
1. Accepting the first quote without comparing
This is the most common and most costly mistake. Price per watt can vary significantly between installers for the same home, and without a point of comparison, you have no way of knowing if the price you’re being offered is reasonable.
How to avoid it: compare at least 3 or 4 quotes from different installers, making sure each one includes the same system size, comparable equipment brand, and warranty scope. Comparing “apples to apples” is the only way to tell if a price is competitive or inflated.
2. Not verifying the installer’s license and reputation
In Texas, electrical and roofing work requires specific licenses. Hiring a company without a verifiable license — or a subcontractor the sales company never mentions — is both a quality and legal risk: if something goes wrong, it can be hard to determine who’s responsible.
How to avoid it: ask for the installer’s license number and verify it independently. Check verified reviews (not just the ones the company shows on its own site) and ask how many years they’ve specifically operated in your area of Texas.
3. Not checking your roof’s condition before installing
A frequent mistake is installing panels on a roof that will need replacement within the next 10 to 15 years. Removing and reinstalling a solar system to replace the roof underneath carries a significant additional cost that many homeowners don’t anticipate.
How to avoid it: if your roof is more than 15 years old or shows signs of wear, consider repairing or replacing it before installing panels, not after. A certified, transparent installer should bring this up during the assessment rather than ignoring it to close the sale faster.
4. Getting drawn in by “$0 down” offers without understanding the full contract
Leases and power purchase agreements (PPAs) with “$0 down” are appealing because they require no upfront payment, but that doesn’t automatically make them the best option. Under these arrangements, the provider — not you — owns the system and captures the tax benefits; you pay a monthly fee or a rate for the energy produced, typically for 20 to 25 years.
How to avoid it: before signing, ask explicitly: who owns the system? How does the monthly payment increase over time (annual escalator)? What happens if I sell my house before the contract ends? These questions usually reveal whether the “$0 down” deal actually makes sense for you, or whether you’ll end up paying more long-term than if you’d bought the system outright.
5. Not knowing your right to cancel the contract
Many homeowners don’t know that under the FTC’s federal “cooling-off rule,” you have the right to cancel a contract signed at your home within three business days, without penalty. Documented cases in Texas show that some door-to-door sales companies simply don’t disclose this right to their customers, especially to older adults.
How to avoid it: if you signed a contract under pressure, at your home, and had second thoughts, check the signing date: if you’re within the three-business-day window, you have the legal right to cancel in writing, with no need to justify the reason.
6. Not requiring the contract to match exactly what was promised verbally
A repeated pattern in Texas consumer complaints is that the price, estimated savings, or equipment mentioned during the sales pitch doesn’t match what ultimately appears in the signed contract. Once signed, what’s legally binding is the written document, not the salesperson’s verbal promise.
How to avoid it: read the entire contract before signing — not just the summary or first page — and compare it against what you were told verbally. If there’s a discrepancy, ask for it to be corrected in writing before signing, or don’t sign at all.
7. Underestimating (or overestimating) the system size you need
An incorrectly sized system is a costly mistake in either direction: one that’s too small doesn’t cover your actual usage and doesn’t maximize your savings; one that’s oversized means paying for capacity you won’t use, especially if your solar buyback plan pays little for the excess energy you send to the grid.
How to avoid it: ask that sizing be based on your actual electricity bills from the last 12 months, not a generic estimate. A serious installer will ask for this information before proposing a system size.
8. Not researching your solar buyback plan before signing
Since Texas doesn’t have a statewide mandatory net metering requirement, each electricity retailer sets its own buyback rate for excess solar energy. Signing a solar contract without reviewing (or switching) your electricity plan can mean you end up selling your excess power at a very low rate, reducing your projected savings.
How to avoid it: before installing, check what buyback plan your current retailer offers and compare it against other options available in your area. A good installer or advisor should help you with this comparison as part of the process, not leave it as a task for you to figure out alone after installation.
The golden rule: compare, verify, and read everything before signing
Most of these mistakes share the same root cause: rushing the decision without comparing options or checking the fine print. A solar system is a long-term investment, and taking a couple of extra weeks to compare certified quotes almost always translates into thousands of dollars of difference — in your favor — over the following 25 years.

Frequently asked questions about mistakes when hiring solar installers
How many quotes should I compare at minimum?
It’s recommended to compare 3 to 4 quotes from different installers, with the same system size and warranty scope, before making a decision.
What questions should I ask an installer before hiring?
At minimum: license number, years of experience specifically in your area of Texas, brand and warranty of the proposed equipment, who owns the system (if it’s a lease/PPA), and how the proposed system size was calculated.
Is it always better to choose the cheapest quote?
Not necessarily. A price well below the rest may reflect lower-quality equipment, weaker warranties, or a system undersized for your actual usage. Price should be evaluated alongside equipment, warranty, and installer reputation.
What should I do if I already signed a contract and think I made a mistake?
If you signed less than three business days ago and did so at your home, you have the legal right to cancel without penalty under the federal “cooling-off rule.” If that window has passed, review the contract for its specific cancellation terms or consult a consumer attorney.
Should I wait for prices to drop further before installing?
Since electricity rates in Texas have risen steadily in recent years, every year you wait is also another year paying higher rates for grid electricity. The decision should be based on comparing the current installation cost against projected savings, not on waiting for a hypothetical future price drop.
