Tesla Solar Roof vs. Solar Panels vs. Ground-Mount: What Actually Works on a Rural Home

Here's the short answer, and it changed in August 2026: Tesla stopped selling its Solar Roof. Installers were told the glass tiles could no longer be ordered, and Tesla's Solar Roof page now redirects to its conventional solar panels page. Tesla has made no public statement about it.

That leaves three live options. Conventional rooftop panels are the cheapest way to make electricity and the easiest to service. Ground-mount arrays cost more upfront but sidestep your roof entirely and shed snow better. Solar shingles — now led by GAF Timberline Solar, since Tesla is out — are a real roof that also makes power, but only make sense when you need a new roof anyway and will pay a large premium for the look.

The deciding factor is usually your roof's age, your trees, and your snow: panels last 25 to 30 years, so the roof underneath has to last that long too.

The comparison, side by side

Cost ranges are before incentives. The federal residential solar credit (Section 25D) ended for installations after December 31, 2025, so budget without it.

What a solar roof actually is

A solar roof is not panels on a roof. It is the roof: the roofing material itself contains photovoltaic cells, and the whole surface replaces shingles, underlayment, and flashing.

Only part of the roof generates power: on a Tesla Solar Roof, roughly 30 to 60 percent of the tiles were active solar tiles, the rest matching non-solar tiles that just keep the weather out. GAF's system is similar, with 40 to 60 percent of the roof covered in energy shingles. So a solar roof needs more roof area than a panel array to make the same power, and shaded or north-facing slopes contribute nothing but roofing.

The product lives or dies as a roofing product: the tiles have to shed water for 25 years and be repairable by someone who can get the parts.

The Tesla Solar Roof, honestly — including the part where you can't buy one

Tesla unveiled the Solar Roof in 2016 promising 1,000 installations a week. Over roughly seven years, about 3,000 were installed in the United States, per Wood Mackenzie's estimate. In August 2026, Electrek reported Tesla had told its certified installers the tiles were no longer available to order, and TechCrunch confirmed the next day that Tesla's Solar Roof pages redirect to its solar panels page. Tesla has said nothing publicly.

If you already own one, your 25-year warranties still stand on paper — but repairs need a Tesla-certified technician, the tiles are proprietary, and no spare tile sits on a supply-house shelf.

Tesla pricing, and why we won't give you a single number

Tesla never published a per-watt or per-square-foot price list. Every quote was per project, priced by roof size, complexity, and solar coverage. Third-party estimates of what people actually paid disagree so widely that printing one figure as "the price" would be dishonest.

The most-cited average is about $106,000 before incentives for a typical home, reported by Today's Homeowner in 2026 (2,000-square-foot home, 6.14 kW) and independently by Electrek in May 2026. That works out to roughly $15–$16 per watt — about five times the per-watt cost of conventional panels. Other 2026 roundups put per-square-foot figures anywhere from the low $20s to about $63, which is exactly the spread you get when a manufacturer doesn't publish prices.

What moves the number: roof size and complexity, the share of active solar tiles, tear-off and deck repairs, batteries bundled into the quote, and local labor rates.

If you are quoted remaining Tesla stock, or any solar shingle system, get these in writing: the total installed price with tear-off itemized separately, the system size in kilowatts, the warranty documents (not a sales sheet), and who services it if the installer closes. Compare it against a panel quote plus a standalone re-roof — that is the honest benchmark.

GAF Timberline Solar: the solar shingle you can still buy

With Tesla out, GAF Energy's Timberline Solar is the solar shingle most rural homeowners will be offered. Each energy shingle produces 57 watts, and roofers install it with the same tools as an asphalt roof. Warranties: 25 years on product and power (84.8 percent at year 25), 15-year wind at 130 mph.

GAF has also never published a price list. The best-sourced figure is GAF's own filing with the Consumer Product Safety Commission, which put the roughly 2,100 recalled systems sold at $40,000 to $100,000 — roughly double a conventional panel system, before you count the roof itself. Like Tesla's product, it requires a full roof replacement; it cannot be added to an existing roof.

Conventional rooftop panels: the default, for good reason

A conventional system is panels on racking, bolted through flashing into your rafters. It is the cheapest way to make solar electricity, by a wide margin. The national benchmark from the Department of Energy and NREL (2025Q1) puts an 8 kW residential rooftop system at $2.78–$2.95 per watt-DC installed — low-to-mid $20,000s for a typical system. Panels are 400-watt modules at about 20 percent efficiency, with 25-year performance warranties and median degradation of about 0.5 percent a year.

Panels win on output per square foot, because every square foot generates, and on service, because the parts are standard: any qualified installer can swap a failed panel, microinverter, or optimizer. The tradeoff is that the system is only as good as the roof under it, and it looks like solar panels on a roof. If the look bothers you, that is a real preference — just price it honestly against the premium a solar shingle roof charges for invisibility.

What moves the number: system size, roof complexity and height, panel and inverter brands, permitting and interconnection fees, and local labor rates.

Your roof's age is the deciding factor

This is the single most expensive mistake in residential solar. Panels last 25 to 30 years, so if your roof has five years left, mounting panels on it means paying to take them off, re-roof, and put them back — roughly $1,500 to $6,000, about $200 to $300 per panel, according to EnergySage, on top of the roof itself.

The Department of Energy's homeowner guide says the same: have an installer, a roofer, or a structural engineer assess the roof, and know when it was last replaced. EnergySage's rule of thumb is that an asphalt roof over 10 years old probably should be replaced before panels go on. On an older farmhouse, check the decking for soft spots and rot, and look for sagging rafters. Panels add only 2 to 4 pounds per square foot — weight is rarely the problem; hidden rot is.

• Roof has 20+ years left: conventional panels are the obvious pick. The roof and the panels age out together.
• Roof needs replacing in the next few years: this is the one window where a solar shingle makes sense — you were paying for a roof anyway. Otherwise, re-roof first, then put panels on the new roof. Doing both at once saves money on labor and scaffolding, per the Department of Energy's consumer guide.
• Roof is failing now and you can't re-roof yet: a ground-mount array lets you go solar without touching the roof.

Snow: tilt decides, and you can't change your roof's pitch

Snow-covered panels produce essentially nothing until they shed. A multi-site study put annual snow losses at 0 to 20 percent of snow-free yield, depending on location and tilt — steeper arrays lose less. In northern states, NREL studies found properly tilted arrays (30 degrees or more) lose only about 2 to 5 percent a year to snow.

A solar roof sheds snow exactly like the roof it is — at whatever pitch your house was built with. Conventional rooftop panels are the same: their tilt is your roof's pitch, and most residential roofs sit at 18 to 30 degrees. A ground-mount array is the only option where you choose the tilt. Set it steeper — 35 to 45 degrees is common in northern climates — and snow slides off faster.

Reach matters too: never climb onto a snowy roof to clear panels. A ground-mount array can be cleared from the ground with a soft roof rake — though tilted panels usually shed snow themselves within a day or two of sun.

Trees and shade: the quiet deal-breaker

Wooded lots and solar are natural enemies. Shade does not just trim output proportionally — on a string-inverter system, one shaded panel drags down the whole string it is wired into. The fix is module-level electronics: microinverters or power optimizers, which let each panel produce at its own maximum. In NREL testbed testing, microinverters recovered 3.7 percent under light shade, 7.8 percent under moderate, and 12.3 percent under heavy shade, versus a plain string inverter.

That matters differently by option. A ground-mount array can be sited in the open part of your land, away from the tree line, which often solves the shade problem before it starts. A rooftop array takes whatever shade your roof gets; the only remedies are trimming trees or paying for microinverters. A solar roof is the least flexible of all: the active tiles are fixed to the roof planes, so a shaded slope is dead weight. Get a real shade analysis before you sign — hour-by-hour modeling, not a salesman's glance at the trees.

Ground-mount on acreage: the rural advantage

If you have the land, a ground mount solves the two problems that plague rural rooftop solar: an old roof and a shaded one. There are no roof penetrations, so there is nothing to leak. The array can be tilted and aimed for ideal production, and everything is at ground level, so cleaning, snow clearing, and repairs are easy.

The price is real. A ground-mount system runs roughly 10 to 25 percent more than an equivalent rooftop system. The extra money goes to engineered racking, concrete footings or ground screws, trenching conduit back to the house, and more labor hours. On a 10 kW system, one Hudson Valley installer's 2026 breakdown put the premium at about $4,000 to $6,000. In exchange, the array typically produces 10 to 25 percent more energy per installed watt, at the ideal tilt with better airflow.

What moves the number: distance to your electrical panel (longer trench, more cost), soil and rock conditions for the footings, and fixed vs. seasonally adjustable racking.

Two things to check first. Zoning: ground arrays are accessory structures, and the rules vary wildly — some townships require 30- to 50-foot setbacks, cap height at 10 to 15 feet, or set a minimum lot size. And the trench: burying conduit tears up the yard between the array and the house, and the longer the run, the more it costs.

The well-pump constraint — it's the inverter, not the array

Whichever array you choose, the same rural constraint applies: your well pump is almost certainly the largest motor in the house, and motors are brutal at startup. A typical 1/2 HP submersible draws about 1,000 watts running but needs roughly 7,700 watts for the first few seconds — about 32 locked-rotor amps at 240 volts. The array does not decide whether that pump starts. The inverter and the battery do.

This matters most if you want outage protection. A standard grid-tied system — solar roof, panels, or ground mount — shuts itself off in an outage by design, under anti-islanding rules (UL 1741). To keep power on, you need a battery, a battery-ready inverter, and islanding equipment. Size the inverter for the pump's surge, not your average load. Our solar vs. generator guide covers the pump math, and our backup power guide covers why an outage is a plumbing event on a well-and-septic home. Run your own numbers with the generator size calculator or the sizing guide first.

When a solar roof won't help

A solar roof — Tesla's or GAF's — is the wrong tool in several common situations:

• Your roof is fine and has decades left. Tearing off a good roof throws away roofing life you already paid for. Panels on the existing roof are cheaper and do the same job.
• Your roof is heavily shaded. The active tiles on a shaded slope generate little, and you cannot move them.
• Your roof is cut up with dormers, valleys, and skylights. Solar shingles need large, clean roof planes; a complex farmhouse roof drives the price up and the active-tile share down.
• You need the system serviced by whoever is available. A solar roof is proprietary. If the manufacturer exits — as Tesla just did — or the local certified installer closes, repairs get slow and expensive. Standard panels can be serviced by almost any solar company.
• You are buying mainly for outage protection. A solar roof without a battery goes dark in an outage, exactly like panels without a battery. The roof is not the backup; the battery is.

Which one is right for your situation?

When none of them yet

Sometimes the right move is to wait:

• The roof needs replacing within a few years and you don't want a solar roof. Do the roof first, then panels. Paying $1,500 to $6,000 later to remove and reinstall panels is a tax on impatience.
• Heavy shade and no clear site. No array design fixes a site with no sun.
• No good ground-mount site and a bad roof. Fix the roof, then reassess. A ground array in a shaded hollow is no better than panels on a shaded roof.
• You're counting on incentives that no longer exist. The federal 30 percent credit ended for installations after December 31, 2025. Any payback math built on it needs redoing from current law.
