$0-Down Solar, Explained Like You're Busy

You're busy, so here's the whole thing in one breath: 'free solar' and '$0 down' are advertising phrases, not products. Every real solar deal is a lease, a loan, or cash. Each has a different owner, a different monthly picture, and a different answer to 'what happens when I sell.' Learn the three and the ads stop being confusing.

'$0 down' describes the first payment, not the total. 'Free' means the money goes to a system instead of the utility — not that it's free. Judge the contract, never the adjective.

The three ways to get solar

Lease / PPA — you rent, someone else owns

A third party owns the panels on your roof. You either lease the equipment for a monthly fee or, with a PPA, pay for the power it produces. This is what most '$0 down / free solar' ads are selling. The upsides are real: little to nothing upfront, maintenance typically handled by the provider, and a predictable payment. The catches to read for are an escalator (a clause that raises your payment a set percentage every year and compounds over the 20–25 year term) and how the contract transfers when you sell your home.

Loan — you own it, a lender fronts the cost

You own the system and pay a lender over a term you choose — often 10 to 15 years — then own the asset outright with no more payments. You keep all the production. Watch for dealer fees baked into some solar loans that can quietly raise the real price, and compare the loan's total cost against cash and against a lease.

Cash — you own it, no financing at all

Pay upfront and there's no term, no lender, no escalator — usually the lowest lifetime cost and the strongest long-term economics. The trade-off is the large upfront outlay and the opportunity cost of that money. If you can and want to, it's the simplest ownership path.

The 2026 tax reality — read this before any 'saves you 30%' pitch

This changed recently and a lot of quotes haven't caught up. The 30% federal residential tax credit (Section 25D) ended for owned systems — cash or loan — placed in service after December 31, 2025. So a 2026 owned purchase generally cannot claim that 30% credit, and any proposal assuming you personally will is a red flag. On a lease/PPA, the provider that owns the equipment may claim a separate commercial credit, which you'd only see indirectly as a potentially lower payment. Tax situations vary, so confirm your specifics with a tax professional rather than a sales sheet.

The Florida perks are separate and still stand: solar equipment is exempt from state sales tax, 100% of the added home value is excluded from your property-tax assessment (Fla. Stat. 193.624), an HOA can't outright ban rooftop solar (Fla. Stat. 163.04), and there's no state income tax. None of those were changed by the federal credit ending.

So which is right for you?

It depends on your goals and your numbers, and anyone who answers before seeing them is guessing. Cash or a loan usually wins on long-term economics if you can carry it and want to own the asset. A lease can fit someone who wants zero upfront, values maintenance-included simplicity, and would rather not own. The mistake isn't picking one — it's picking based on an ad. Whatever you're quoted, model the lifetime total (escalator included), not the friendly monthly number, and compare it against staying with the utility.

Questions worth asking

• Is this a lease/PPA, a loan, or cash — and who owns the panels?
• If it's a lease, what's the escalator and the lifetime total across the full term?
• If it's a loan, are there dealer fees baked into the price?
• Does the quote assume a tax credit I can actually claim in 2026?
