How to Vet a Tampa Solar Installer (and Avoid the Door-Knocker Lease Trap)
Tampa’s sunshine attracts legitimate solar companies — and an army of door-to-door sales operations whose business model is the contract, not the installation. Here’s how to tell them apart before you sign anything.
The door-knocker lease trap, explained
The most common bad solar deal in Tampa doesn’t start with a bad panel — it starts with a knock on the door and a pitch that sounds like this: “free solar, no money down, lower your electric bill starting next month.” What you’re actually being offered is usually a 25-year lease or power purchase agreement (PPA) in which a finance company owns the system on your roof. That structure isn’t inherently a scam — but the door-to-door version of it routinely hides terms that turn a good deal into a trap:
- The escalator. Many leases/PPAs include an annual rate escalator of 2–4%. That compounds: a payment that looks cheaper than your utility bill in year 1 can exceed it by year 10–12, especially if utility rates don’t rise as fast as the pitch assumed. Always ask for the 25-year total, not the year-1 payment.
- The production guarantee gap. Your payment is often based on estimated production. If the system underproduces (shading they didn’t model, equipment issues), you can end up paying the lease plus a real utility bill. Ask what happens — in writing — if production misses the estimate.
- The roof and the lien. Some agreements file a UCC-1 fixture filing against the system — not a lien on your home, but a recorded interest that must be dealt with when you sell or refinance. Buyers’ title companies flag these routinely. Know exactly what’s being recorded before you sign.
- The “free” framing. Nothing is free: you’re trading 25 years of payments and roof control for $0 down. Compare the 25-year lease total against a purchase quote — with Florida’s property-tax exclusion and sales-tax exemption, purchasing often wins for homeowners who can finance it.
Red flags in any solar pitch
- “Free solar” or “the government pays for your panels” — there is no such program; it’s a lease/PPA pitch.
- A promise of the 30% federal residential credit on a 2026 purchase — that credit expired December 31, 2025.
- “Net metering is ending next month, sign today” — manufactured urgency; check your utility’s actual published tariff.
- No license number, or a number that doesn’t verify on the DBPR site (see our license guide).
- Quotes based only on satellite imagery with no site visit, roof inspection, or shading analysis.
- Refusal to itemize equipment brands, warranty terms, and the production estimate’s assumptions.
- Pressure to sign on the first visit, “today-only” pricing, or discouraging you from getting other quotes.
The vetting checklist (use it on every bidder)
- Verify the license at myfloridalicense.com — status active, type covers solar, name matches the company.
- Get three quotes minimum — and make at least one of them a purchase quote even if you’re leaning toward a lease, so you can compare 25-year totals honestly.
- Demand the production estimate in kWh/year with the shading, orientation, and degradation assumptions spelled out.
- Read the escalator and term clauses yourself. On a lease/PPA: annual escalator %, total term, buyout options, what happens on sale/refinance of the home, and who handles maintenance and monitoring.
- Confirm permits and interconnection in writing. Who pulls the building permit? Who files the utility interconnection? What’s the timeline to permission to operate?
- Check the roof plan. How old is your roof? What attachment method for your roof type? What happens to the roof warranty? If your roof has under ~10 years of life left, price the roof replacement into the decision.
- Search the company, not just the reviews. How long have they operated in Florida under this name? (Solar installers rebrand frequently.) Check DBPR complaint history and how long they’ve held the license — not star ratings, which can be gamed.
What a good installer looks like
The best Tampa solar companies share a profile: Florida-licensed (verifiable), in business locally for years under one name, doing real site surveys before quoting, showing you production math and equipment brands without being asked, pulling permits without complaint, and equally comfortable quoting a purchase or explaining why a lease doesn’t fit you. They answer the escalator question before you ask it. Hire that company — however you found them.
