⚠️ 2026 update on the federal tax credit

The 30% federal residential solar tax credit (Section 25D) expired on December 31, 2025 for systems you buy with cash or a loan. Cost and savings figures on this page that assume that credit may be out of date. Two things still apply: Nevada's sales-tax and property-tax exemptions and NV Energy net metering, and systems on a lease or PPA may still qualify for a federal incentive through the end of 2027. For numbers that reflect today's incentives, book a free review and talk to a tax professional about your situation.

$0 down solar in Las Vegas is real, but the headline rate isn't what you actually pay. Most $0-down loans bake in an 18–28% dealer fee on top of the system price, which is how lenders fund the "low" advertised APR. The deal can still work — you just need to see the real cost, not the marketing version.

How a $0-down solar loan actually works

You sign for a system at, say, $24,000. The lender (GoodLeap, Sunlight Financial, Mosaic, Service Finance, etc.) advances the installer the full amount immediately. To make the advertised 4.99% or 5.99% APR work for the lender, the installer pays them a "dealer fee" of 18–28% of the loan amount. That fee gets added to your principal. So your $24,000 system becomes a ~$30,000 loan. You finance the markup.

The two prices every installer should show you

When I quote a Las Vegas homeowner, I show:

  • Cash price: what you'd pay if you wrote a check today
  • Financed price: cash price + dealer fee, plus 25 years of interest

If a rep only shows you a monthly payment, ask for both numbers in writing. Reps who refuse usually have a reason.

Real example — same system, three ways

8 kW Henderson install, gross $24,000:

  • Cash: $24,000 (after Nevada's sales-tax exemption; the 30% federal credit ended Dec 31, 2025)
  • HELOC at 8.5%: $24,000 financed, ~$48 in interest premium per month vs cash
  • $0-down solar loan at 5.99%, 22% dealer fee: $29,280 financed, monthly ~$189, total paid ~$56,700

The $0-down loan costs about $32,700 more than cash and $24,000 more than a HELOC over the loan term. The "low" 5.99% rate is mostly a fiction made possible by the dealer fee.

When $0-down still wins

It's not always wrong. $0-down works when:

  • You don't have $20K cash and don't have HELOC headroom
  • Your monthly loan payment is meaningfully below your current NV Energy bill (cash-flow positive day one)
  • You plan to stay in the house 10+ years

The re-amortization trap

Many solar loans were structured with a "low payment" assuming you'd apply a tax credit as a principal reduction in the first year or two. With the 30% federal credit gone for purchased systems (it expired December 31, 2025), there's no credit to apply — so if a 2026 loan is still written around a "voluntary prepayment" assumption, your payment can jump 40–60% if you don't make that lump-sum yourself. Read the loan disclosure carefully and ask exactly what payment you owe with no prepayment.

The federal tax credit is gone for purchased systems

This used to be the headline benefit of financing — claim the 30% credit, drop it on your principal. That credit expired December 31, 2025 under the One Big Beautiful Bill Act, so there's no 30% to claim on a cash or loan purchase in 2026. Only lease and PPA systems can still capture a federal incentive (through end of 2027), and there the third-party owner keeps it. Background is at the IRS Residential Clean Energy Credit page. Lean on Nevada's surviving incentives and the rising-rate hedge instead.

Why national door-to-door reps push $0-down hardest

Dealer fees fund their commission structure. A $0-down financed deal can pay a rep 2–3x what a cash deal pays. That's not a moral judgment — it's just why the pitch is structured the way it is. Local referral-based installers (me included) typically don't lean on $0-down because we're not paying a sales floor.

HELOC vs solar loan — almost always HELOC

If you have home equity, a HELOC at 8–9% beats a $0-down solar loan at 5.99%-with-dealer-fee almost every time. The interest is also potentially deductible (talk to your CPA). A HELOC keeps your cash price as your real price.

Red flags in $0-down quotes

  • Rep won't show you the cash price
  • Loan disclosure has different numbers than the proposal
  • "This rate is only good today" pressure
  • Production guarantee uses unrealistic NV Energy rate inflation (5%+) to make payback look fast
  • No itemized BOM

How to negotiate a $0-down deal

Ask the installer to quote it both ways. Then ask them to reduce the dealer fee — it's often negotiable, especially in late-month or late-quarter situations. A 22% dealer fee at $24,000 is $5,280 of margin. Some of that is movable. I cover this in detail on the about page and during quote walkthroughs.

Bottom line

$0-down solar in Las Vegas works if your monthly outlay drops day one and you plan to stay long enough to ride out the loan. It's a worse deal than cash or HELOC almost always — but "worse than cash" can still be much better than paying NV Energy forever.

Frequently Asked Questions

Is $0 down solar really $0 down in Las Vegas?
Yes for the upfront payment — you don't write a check at install. But the loan amount is typically 18–28% larger than the cash price of the system because of a dealer fee built into the loan. So you do pay it, just spread out over 20–25 years with interest. The "$0 down" refers to the day-one out-of-pocket, not the total cost. Cash and HELOC almost always beat $0-down financing on total dollars paid.
What is a dealer fee on a solar loan?
A dealer fee is a payment from the installer to the lender to "buy down" the advertised interest rate on a $0-down solar loan. It's typically 18–28% of the system price. The installer recovers it by inflating the financed price relative to the cash price. So the same system might be $24,000 cash and $30,000 financed at the same APR. The dealer fee makes the headline interest rate possible.
Can I claim the 30% federal solar tax credit on a financed system in 2026?
No — the 30% Residential Clean Energy Credit expired December 31, 2025 for systems you buy, including loan-financed ones. There's no federal credit on a cash or loan purchase placed in service in 2026. Only lease and PPA (third-party-owned) systems can still capture a federal incentive, through the end of 2027, and the company that owns the panels keeps it. Watch out for 2026 loan offers still written around a "tax-credit prepayment" assumption — there's no credit to apply, so confirm your real payment before signing.
Should I use a HELOC or a solar loan to finance my system?
A HELOC almost always beats a $0-down solar loan on total cost, even though the HELOC rate looks higher on paper. The reason is the dealer fee — solar loans look cheap because the principal is inflated. A HELOC at 8.5% on $24,000 typically costs less over the term than a 5.99% solar loan on $29,300. HELOC interest may also be deductible if used for home improvement (verify with your CPA).
What happens to the prepayment assumption on a solar loan now that the tax credit is gone?
Many $0-down solar loans were structured with a low introductory payment that assumed you'd make a 26–30% principal payment in the first year or two using your federal tax credit. That credit expired December 31, 2025 for purchased systems, so there's no credit to apply. If a 2026 loan still bakes in that voluntary-prepayment assumption and you don't make the lump-sum yourself, the loan re-amortizes and your monthly payment can jump 40–60%. Read the loan documents and confirm the payment you owe with zero prepayment before signing.
