Introduction: The Texas Solar Sales Environment
Texas is one of the largest solar markets in the United States, which has attracted both excellent local installers and a significant number of bad actors. The deregulated Texas electricity market, combined with rapidly rising electricity rates and high solar potential, creates the conditions for aggressive sales tactics targeting homeowners who don't know what a reasonable contract looks like.
Door-to-door solar sales teams are active in most major Texas metropolitan areas. Some operate for legitimate companies; others are lead-generation operations with loose connections to the actual installation company. Texas has relatively light solar contractor licensing requirements compared to some states — a contractor needs a Texas TECL (Electrical Contractor) license, but the specific requirements for solar installation aren't as rigorous as California or Massachusetts.
The following eight red flags represent patterns we've seen repeatedly in consumer complaints and problematic Texas solar contracts. None of them are necessarily instant disqualifiers — context matters. But each deserves careful scrutiny before you sign.
Red Flag #1: "Free Solar" Claims
If a solar salesperson leads with "free solar" or "solar at no cost to you," you are being pitched a solar lease or power purchase agreement (PPA), not a free system.
Under a solar lease, a solar company installs panels on your roof and you pay a monthly lease payment — often for 20–25 years. The "no upfront cost" is accurate; the ongoing cost is not disclosed as prominently. Under a PPA, you pay the company a per-kWh rate for electricity produced by panels on your roof — also for 20–25 years.
The problems with leases and PPAs in Texas:
- You don't own the system, so you don't receive the 30% federal tax credit (the solar company does)
- The panels are a lien on your home that must be resolved when you sell — either the buyer assumes the lease or you buy it out, often for tens of thousands of dollars
- Many leases include escalation clauses (see Red Flag #2)
- Home buyers increasingly reject homes with solar leases attached
In nearly all Texas cases, purchasing solar through a loan is financially superior to leasing, even when the loan has interest. You keep the tax credit, you own an asset, and you don't encumber your home.
Red Flag #2: Escalating Payment Clauses
In lease or PPA contracts, escalation clauses allow the solar company to increase your monthly payment by a fixed percentage each year — typically 2–3% annually. Over a 25-year contract, a 2.9% escalator turns a $150/month initial payment into $300/month by year 25 — even if your electricity costs stay flat or decline.
The sales pitch for escalators is that electricity rates "always go up" and the escalator will still result in net savings. This may or may not be true for any specific homeowner, and the solar company is making this bet using your money over your lifetime. Electricity rates in Texas's deregulated market are not guaranteed to increase at any specific rate. Some retail plans have actually decreased year-over-year.
What to look for: Read the PPA or lease contract for the specific annual escalation rate. A 0% escalator is called a "fixed-rate PPA" — some companies offer them. Any escalation above 2% deserves serious scrutiny. A 3% escalator over 25 years doubles your payment.
Red Flag #3: Vague or Unenforceable Production Guarantees
Most solar companies offer "production guarantees" — a promise that your system will produce a certain number of kWh per year. These guarantees are only valuable if the contract specifies exactly what happens when production falls short.
Red flag language includes: "We guarantee your system will perform to expectations," "Your system is designed to offset [X]% of your usage," or "We stand behind our systems 100%." None of these statements are legally enforceable without specific numbers and specific remedies.
What a real production guarantee looks like:
- A specific annual kWh production number (e.g., "8,500 kWh per year")
- A specific measurement methodology (e.g., "measured by the monitoring system installed with the system")
- A specific remedy if production falls below the guaranteed level (e.g., "Company will pay homeowner $0.12 per kWh of the shortfall")
- Exclusions for homeowner-caused issues (shade added after installation, panel damage, etc.)
If the contract doesn't include all four elements, the "guarantee" is a marketing statement, not a contractual protection.
Red Flag #4: Out-of-State Contractors Without Local Presence
Texas's large solar market attracts national companies that parachute in with aggressive sales teams, complete a burst of installations, and then become difficult to reach for service and warranty claims. This pattern has played out repeatedly in the Dallas, Houston, and San Antonio markets.
Questions to ask before signing:
- How long have you operated specifically in Texas (not nationally)?
- Where are your service technicians based? How quickly can someone come to my home if there's a system issue?
- Can I speak with three references from customers you installed in my ZIP code in the past 12 months?
- Who provides warranty service if your company is acquired or closes?
Check the Texas Secretary of State business filings to see how long the company has been registered in Texas. Check the BBB for complaints. Search "[Company Name] Texas reviews" and "[Company Name] Texas lawsuit" — not just the testimonials on their own website.
Red Flag #5: Permit Responsibility Ambiguity
Every Texas solar installation requires permits — at minimum an electrical permit from the local municipality, and in many jurisdictions a separate building permit. If your installer doesn't pull permits, you have an unpermitted electrical installation on your home. This affects:
- Your homeowners insurance coverage (many policies exclude unpermitted work)
- Your ability to sell the home (buyers' inspectors will flag unpermitted electrical work)
- Your TDU interconnection (utilities won't approve interconnection without permits)
- Your ability to claim the federal tax credit (the IRS doesn't require permits, but unpermitted work creates audit risk)
What to require: The contract should explicitly state that the contractor is responsible for pulling all required permits before installation commences and that the final permit inspection is the contractor's responsibility before the system is turned on. Ask to see the permits before installation day.
Red Flag #6: Roof Damage Liability Gaps
Solar installation requires penetrating your roof to mount racking hardware. When done correctly with proper flashing and sealant, this is not a problem. When done incorrectly — or when a low-quality installer cuts corners — you can end up with roof leaks that manifest months after installation, long after the crew has moved on to other jobs.
What to look for in the contract:
- Does the contract include a workmanship warranty that specifically covers roof penetrations? A real workmanship warranty covers leaks caused by installation for at least 10 years.
- What is the contractor's process for restoring roof penetrations if panels need to be removed (for a roof replacement, for example)? Who pays for panel removal and reinstallation?
- Does the company carry liability insurance sufficient to cover roof damage? Ask for a certificate of insurance naming you as additional insured.
Before signing, inspect the company's installation photos and ask to speak with a customer whose installation is 3+ years old. Roof penetration problems typically manifest within the first 2 years.
Red Flag #7: Unspecified Equipment
Solar contracts that don't specify the exact panel brand, model, wattage, and inverter specifications give the installer flexibility to substitute lower-quality equipment after you've signed. "Tier 1 panels" and "name-brand inverters" are meaningless without specifics.
A properly specified solar contract should include:
- Panel manufacturer, model number, wattage per panel, and quantity
- Inverter manufacturer and model number (string inverter, microinverter, or power optimizer + inverter)
- Racking system manufacturer and model
- Monitoring system specifications
- Battery brand and model (if included)
If equipment substitution is necessary (supply chain issues), the contract should require your written approval before substituting, and require that substituted equipment is of equal or better specifications and carries equal or better warranties.
Red Flag #8: Confusing Lease vs. Purchase Language
Some contracts are deliberately written to obscure whether you're purchasing or leasing the system. Phrases like "solar service agreement," "energy services agreement," and "solar subscription" may be used instead of "lease" to avoid triggering consumer protections that apply to leases or to confuse the distinction.
Before signing any solar document, determine unambiguously: at the end of this contract, do I own the solar system or does the company? If you're not clear on the answer from the contract language, the answer is probably "the company."
Purchase contracts should include a bill of sale or equivalent documentation that transfers ownership to you upon final payment. If there's a lien against the panels (for financing), that lien should be released upon payoff. Ask your installer to walk you through exactly what happens to ownership at each stage of the process.
Red Flag Checklist
Before signing any Texas solar contract, verify each of the following:
Frequently Asked Questions
The biggest red flags are: "free solar" language obscuring a lease, escalating monthly payments of 2–3% annually, production guarantees without specific kWh numbers and remedies, out-of-state contractors with no local service team, and contracts where the contractor isn't clearly responsible for permits. See our full checklist above before signing.
Buy — either outright or through a loan — in almost all Texas cases. When you buy, you capture the 30% federal tax credit (worth thousands), own an asset that increases home value, and keep all electricity savings. With a lease, the solar company keeps the tax credit, you don't own the system, and you take on a 20–25 year obligation that complicates home sales.
No. "Free solar" means a solar lease or PPA — no upfront cost, but 20–25 years of monthly payments that often escalate annually. You don't own the panels, you don't get the tax credit, and you inherit a complex obligation that complicates selling your home. There is no free solar.
Verify: the Texas TECL license at tdlr.texas.gov, BBB rating and complaint history, local references (not just website testimonials), specific equipment specifications in the contract, permit responsibility language, and the production guarantee specifics. For contracts over $15,000, having an attorney review the document is money well spent. Also see our full checklist in this guide.
