The 8pm Doorbell: How to Vet a Solar Rep in 5 Questions

Picture it: 8:47pm, dinner's barely done, and there's someone on your porch with a lanyard, a tablet, and remarkable enthusiasm about your roof. Solar can be a genuinely good decision — but a doorstep at night, under time pressure, is the worst possible place to make it. The good news is you don't have to be confrontational to protect yourself. You just have to ask a few questions and watch how the answers land.

The single most useful sentence you can say: 'Leave the proposal and I'll review it.' Everything a good deal offers is still there tomorrow. Anything that evaporates overnight was never a real deadline — it was a quota.

The five questions

1. Is this an owned system or a lease/PPA?

This one answer reshapes everything else — the monthly cost, the tax treatment, what happens when you sell. Owned means you buy the equipment (cash or loan) and hold an asset. Leased or PPA means a third party owns the panels on your roof and you pay them monthly. Neither is automatically bad, but a rep who's cagey about which one you'd be signing is a problem before you even reach the numbers.

2. Does this deal really end tonight?

Watch the reaction closely. Real pricing on real equipment doesn't vanish at midnight. 'Ends tonight,' 'only three spots left in your neighborhood,' and 'the incentive expires this week' are manufactured urgency designed to stop you from thinking or comparing. A confident, honest rep is fine with you sleeping on it. A rep who needs the signature now is telling you something — believe them.

3. Who claims any tax credit, and does your quote assume one I can actually get?

This is where 2026 quotes go wrong. The 30% federal residential tax credit (Section 25D) ended for owned systems placed in service after December 31, 2025 — so a 2026 cash or loan purchase generally cannot claim it. If a rep is waving around a 30% credit on an owned system 'to make the numbers work,' that's a serious red flag. On a lease/PPA the third-party owner may claim a separate commercial credit that you'd only see indirectly. When in doubt, talk to a tax professional rather than trust the pitch.

4. Are the production and savings guaranteed — in writing?

Proposals love big savings numbers. Ask whether the projected production is a marketing estimate or a contractual guarantee with an actual remedy if the system underproduces, and ask what utility-rate assumption the savings depend on. Savings should be a range, not a promise — and if a deal only 'works' under the most aggressive rate-hike assumption, be skeptical. The word 'guaranteed' means nothing unless it's in the signed contract.

5. Who fixes it if your company disappears?

Ask it to their face. Southwest Florida is full of orphaned solar systems whose installers folded or moved on, leaving owners with a fault and no one to call. A 25-year warranty is worthless if the company is gone in three. Ask how long they've operated, whether they self-install or subcontract, and who honors the workmanship warranty if they close. Then verify their license and reviews independently — not from the brochure.

How to end the conversation gracefully

You don't owe anyone a decision on your porch. 'Thanks — leave the proposal and I'll have it reviewed' is polite, firm, and completely reasonable. Then get a second set of eyes before you sign. We'll read any proposal against these questions, flag what doesn't hold up, and show you the real lifetime numbers — free, and with no lanyard.

Questions worth asking

• Is this owned or a lease/PPA, and what's the exact term?
• Does the deal truly expire tonight, or can I review it and decide later?
• Does your quote assume a tax credit I can actually claim in 2026?
• Are production and savings guaranteed in writing, and under what rate assumption?
• Who honors the warranty and services the system if your company closes?
