⚠️ 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 Cost and savings figures on this page that assume that credit may be out of date.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.

Cash wins in Nevada in 2026, then HELOC, then $0-down loan, then lease — in that order, almost every time. The gap between cash and lease over 25 years is typically $40,000–$60,000 on a single Las Vegas home. Here's why, with the math shown.

The four ways to pay for solar

  • Cash: you write a check, you own the system, you get Nevada's tax exemptions
  • HELOC / home equity loan: you finance through your bank, you own the system, you get the Nevada exemptions
  • $0-down solar loan: you finance through a solar lender (GoodLeap, Mosaic, Sunlight), you own the system, but principal is inflated by a dealer fee
  • Lease or PPA: a third party owns the system on your roof, you pay them monthly for the power; this is the only structure that can still capture a federal incentive (through end of 2027), but the owner keeps it

Same Henderson 8 kW system, four ways

System cost $24,000 (cash, after Nevada's sales-tax exemption). The 30% federal credit expired December 31, 2025 for purchased systems, so cash, HELOC, and solar-loan buyers no longer get a federal reduction. Estimated 25-year electricity offset value: ~$87,000 (3% annual NV Energy rate inflation).

  • Cash: Net cost $24,000. Lifetime net: +$63,000
  • HELOC at 8.5%: Total paid ~$30,700. Lifetime net: +$56,300
  • $0-down solar loan, 22% dealer fee: Total paid ~$47,000. Lifetime net: +$40,000
  • 20-year lease: Total paid ~$52,000 (escalator). Lifetime net: +$15,000

Cash beats lease by ~$48,000 over 25 years on the same roof.

Why the lease loses so badly

Three reasons stack:

  1. You don't own the asset — and while a lease/PPA is now the only way to capture a federal incentive (through end of 2027), the leasing company keeps it, not you.
  2. Most leases have a 1.9–2.9% annual escalator, so your "savings vs NV Energy" shrinks every year.
  3. You can't claim Nevada's property tax exemption benefit as cleanly because you don't own the system.

Nevada incentives are now the dollar driver

With the 30% federal credit gone for purchased systems, ownership wins on Nevada's surviving breaks plus net-metering value, not a federal check. Cash, HELOC, and solar-loan buyers all get Nevada's sales-tax exemption (~8.375% in Clark County, applied at purchase) and the property-tax exemption on added home value. NV Energy net metering still credits exports at 75% of retail, locked for 20 years. A lease leaves those ownership benefits on the table.

Home value impact

Owned solar adds resale value (Zillow and DOE data both back this — see DOE solar resources). Leased solar typically subtracts from sale speed because buyers don't want to assume someone else's lease. I've seen Vegas listings sit longer specifically because of inherited leases.

When does a lease actually make sense?

Two narrow cases:

  • You can't qualify for any loan and don't have cash
  • You're 100% certain you'll move in under 4 years and want some bill savings with zero upfront

For everyone else, it's a worse deal.

HELOC vs $0-down solar loan

HELOCs at 8–9% almost always beat $0-down solar loans at 5.99% because the solar loan principal is inflated by a 18–28% dealer fee. Compare total paid, not the rate. I cover this in detail in $0 Down Solar Explained.

Cash vs HELOC — small gap

If you have the cash and no better use for it, write the check. If you'd rather keep liquidity and your HELOC rate is under 9%, HELOC is fine. The gap is usually $5,000–$8,000 over 25 years on an 8 kW system. Not nothing, but not the dealmaker.

Nevada-specific tax considerations

Nevada has no state income tax, and with the federal credit gone for purchased systems, the state's own breaks are now the tax story. The property tax exemption (NRS 361.079) and sales tax exemption (NRS 374) apply to owned systems. These don't apply to leased systems on your roof.

What I quote

I quote cash and HELOC by default for Nevada homeowners. I'll quote a $0-down loan if cash flow is the constraint. I won't quote leases — the math doesn't favor my clients and I'd rather lose the deal than put someone on one. More on my approach on the about page.

Frequently Asked Questions

Is a solar lease ever a better deal than buying solar in Nevada?
Rarely. Two narrow cases: you can't qualify for a loan and don't have cash, or you're 100% sure you'll sell the home in under 4 years and want bill savings with zero upfront. For everyone else, the lease loses to cash by roughly $40,000–$50,000 over 25 years on a typical Vegas home. Note: since the 30% federal credit ended December 31, 2025 for purchased systems, a lease/PPA is now the only structure that can still capture a federal incentive (through 2027) — but the leasing company keeps it, not you, so it doesn't flip the math in your favor.
Is there still any federal solar tax credit in Nevada in 2026?
Only for leases and PPAs, not for systems you buy. The 30% Residential Clean Energy Credit expired December 31, 2025 for purchased (cash or loan) systems. Third-party-owned lease/PPA systems can still capture a federal incentive through the end of 2027 — but the leasing company or PPA provider claims it, not the homeowner, and they don't pass the full value back to you. For owners in 2026, the real incentives are Nevada's sales-tax and property-tax exemptions plus NV Energy net metering, not a federal check.
Does leased solar hurt my home's resale value in Las Vegas?
Often yes. Buyers either need to qualify to assume the lease or the seller has to buy it out at closing — sometimes for $15,000–$25,000. Owned solar typically adds value and is a selling point. Leased solar is a complication on the title and disclosure that can extend days-on-market. I've seen multiple Las Vegas listings sit longer specifically because of inherited solar leases.
Should I use HELOC or a solar loan to buy panels in Nevada?
HELOC almost always wins on total dollars. A $0-down solar loan at 5.99% looks cheaper than a HELOC at 8.5%, but the solar loan principal is inflated 18–28% by a dealer fee that the lender pays the installer. On the same $24,000 system, HELOC typically costs $5,000–$10,000 less over the term than a $0-down solar loan. HELOC interest may also be deductible — check with your CPA.
What's the cheapest way to go solar in Nevada in 2026?
Cash, by a small margin over HELOC. On an 8 kW Henderson system, cash costs $24,000 (after Nevada's sales-tax exemption; the 30% federal credit ended December 31, 2025 for purchased systems). HELOC at 8.5% costs about $30,700 over the term. A $0-down solar loan with a 22% dealer fee runs ~$47,000. A 20-year lease comes in around $52,000. If you have liquidity and no higher-yield use for it, write the check.
