⚠️ 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 Cost and savings figures on this page that assume that credit may be out of date.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.
A Sun City Anthem homeowner with a concrete S-tile roof at roughly 4,500 ft elevation installed a 7 kW system. Cash cost, Nevada sales-tax exempt: $27,430 (the 30% federal credit expired 12/31/2025 for purchased systems, so there's nothing to subtract on a 2026 cash buy). Monthly savings: $182. The HOA cycle ran three weeks. The tile and the elevation both made a real difference in the project — neither in the way the homeowner expected. Tile installs are different beasts from asphalt shingle, and Anthem’s elevation gives a small but measurable production bonus that most installers don’t even mention.
The Starting Point
2,800 sqft single-story, 2006 build, original concrete S-tile roof in good shape. Two retired homeowners, modest electric usage (~860 kWh/month average) but high summer peaks because of medical equipment that ran 24/7. NV Energy bill averaged $185/month, peaking at $290 in August. The medical equipment created a load floor that didn’t exist in most homes — they couldn’t turn it off, couldn’t time-shift it, couldn’t schedule around it. So the system had to cover that constant draw plus normal household load.
The home is in Sun City Anthem, an age-restricted HOA with a published solar policy. Elevation matters here — Anthem sits noticeably higher than the Las Vegas valley floor, and the cooler air actually increases panel production by 1–3% versus an identical install in the basin. Panels lose efficiency as they heat up; thinner air at elevation means slightly cooler operating temps. That’s a real effect, calibrated against NREL’s solar resource modeling.
Why Tile Roofs Are Different
You don't drill through tile. You either lift and re-set tiles around standoffs (the right way) or use specialized hook brackets that go under the tiles into the underlayment and rafter (the more common way for S-tile). Both add labor and parts cost over an asphalt-shingle install. On this roof we used tilt-optimized hook brackets and lifted ~40 tiles total during the install.
Tile install premium: roughly $0.20–$0.35/W over asphalt. On a 7 kW system that's $1,400–$2,450 of extra cost. We came in at the lower end. Why? The tile was concrete S-tile in good condition, the roof had a single dominant slope (no complex valleys or hips), and we’d done two prior installs in the same neighborhood so the crew knew the layout pattern.
One thing to watch on tile: the underlayment. Concrete tile lasts 40+ years, but the felt or synthetic underlayment beneath it lasts 20–25. On a 2006 build, the underlayment was approaching the back end of its life. We flagged it for the homeowner and recommended a partial underlayment refresh under the panel footprint while we had the tiles up. They opted to skip it. That’s a defensible call — it added $2,200 to the project and the underlayment was visibly fine — but I document it so we’re both clear on the decision.
What We Designed
A 7 kW system: 18 panels at 400W, string inverter with optimizers (because one corner of the roof gets shaded by a chimney for 90 minutes). No battery. Tile-specific roof attachments rated for the panel weight plus snow load (yes, even at this elevation we spec for occasional snow — Anthem has had 2-inch dustings in the last decade and the structural code requires a snow allowance).
The HOA Part
Sun City Anthem's architectural review meets bi-weekly. Our submission caught the wrong week of the cycle — we missed the meeting by two days. That added about 12 days to the timeline. Once it was on the agenda, approval was straightforward — the HOA has a clear written policy aligned with NRS 278.0208. Net HOA cycle time: 3 weeks.
If you're in an HOA with a fixed meeting schedule, time your submission to land 5–7 days before a meeting. That single piece of timing can save you two weeks. The committee also appreciates a complete packet — site plan, panel datasheet, contractor license, layout drawing, manufacturer certs. Submitting incomplete paperwork bumps you to the next meeting cycle while the gap gets filled.
The Numbers
| Item | Before | After |
|---|---|---|
| Monthly NV Energy bill | $185 | $3 |
| Annual electric cost | $2,220 | $36 |
| Year-1 savings | $2,184 | |
| System cost (cash, NV sales-tax exempt) | $27,430 | |
| Tile premium included | ~$1,500 | |
| Federal ITC | $0 — expired 12/31/2025 for purchases | |
| Net cash cost | $27,430 | |
| Simple payback | ~9–12 years (cash purchase, post-credit) | |
The bill dropped to nearly nothing because their consumption pattern (modest, daytime-heavy from the medical equipment) aligned perfectly with production. They’re net-positive on credits in spring and fall, which carries them through the lower-production winter months.
What Surprised the Homeowner
The production was about 4% higher than my model predicted. I'd used standard Nevada irradiance data, which is calibrated to the basin. At Anthem's elevation, the cooler operating temps and slightly thinner atmosphere both bumped the panels above model. Pleasant surprise. I’ve since recalibrated my Anthem-specific quotes to add a 2–3% elevation adjustment up front, so I’m not under-promising production for that ZIP.
What We'd Do Differently
I'd have submitted the HOA paperwork the day after our site visit instead of waiting for the contract countersign. We had everything we needed. Holding the submission for the contract cost us a meeting cycle — 12 unnecessary days. That’s now standard practice — submit HOA the day after the site visit, in parallel with the contract process, so the two timelines run alongside each other instead of in sequence.
The Total Cost Stack
- Panels (18 × 400W): $6,480
- String inverter + optimizers: $2,800
- Tile-spec racking and hooks: $2,300
- Electrical work: $1,800
- Permits + HOA + interconnection: $850
- Labor (tile premium): $11,400
- Margin + overhead: $1,800
- Cash price (NV sales-tax exempt): $27,430
The 30% federal residential solar tax credit (Section 25D) expired December 31, 2025 for purchased systems, so there's no federal credit to subtract on a 2026 cash buy. Nevada's sales-tax exemption on solar equipment is already reflected in the price above, and the property-tax exemption keeps the added home value off your assessment. Lease/PPA systems can still claim a federal incentive through the end of 2027.
Why This Isn't Typical (or Why It Is)
If you have a tile roof, expect $0.20–$0.35/W more than the asphalt-shingle benchmark. If you're at elevation (Anthem, parts of Boulder City), expect a small production bonus. If you're in an HOA with a fixed meeting schedule, time your submission. Your bill drop will depend on your consumption profile, which differs from this household. The near-zero residual bill here was a function of modest, daytime-heavy consumption — not the system size.
A separate factor worth mentioning: Sun City Anthem’s population skews older, and many residents I’ve worked with are on fixed retirement incomes. The decision math for them isn’t just about lifetime savings; it’s about whether the system pays back inside the years they expect to be in the home. For an active 65-year-old, a 9–12-year payback works fine. For an active 78-year-old, the math tips toward whether the system adds resale value when the home eventually transfers — which it does in Anthem, where buyers increasingly look for owned solar as a feature. I run that calculation explicitly for every retired Anthem customer rather than assuming the standard payback timeline matches their planning horizon.
