Expert review of Voltaic Solar Roof Tiles

Voltaic Roof Tile is a newcomer in the solar industry, offering an integrated solar roof system aimed at style-conscious homeowners. Founded in 2024 by Ergosun Holdings in Iowa, Voltaic’s product combines the strength of concrete roofing with photovoltaic power generation. The result is a building-integrated solar roof that provides both shelter and energy while maintaining the look of a premium roof. Voltaic’s solar tiles are designed to withstand extreme weather and meet strict building codes (Class A fire-rated and hurricane-wind tested). The newest Voltaic “ICON” solar roof is a high end, storm-proof solar roofing solution meant to blend seamlessly into your home’s architecture, rather than sitting on top of it.

Voltaic’s solar roof tiles deliver solid performance, about 19.2% efficiency, which is on par with standard solar panels and come backed by top tier 25 year warranties covering product quality and power output. However, getting a solar roof like this is a significant project and investment

Pros and cons of Voltaic Solar Roof Tiles

Pros	Cons
Beautiful, seamless appearance: Solar tiles integrate into the roof for high curb appeal (HOA-friendly)	High upfront cost: Significantly more expensive than standard solar panels for the same power
Extreme durability: Class A fire rating and tested to survive 160-180 mph winds, Class 4 hail resistant	Newer company/tech: Voltaic launched in 2024, so it lacks a long track record (though based on the earlier Ergosun design)
Strong 25-year warranty: Covers tile product, power output, and even workmanship if installed by certified partners	Requires roof replacement: Best suited for new construction or when you need a new roof, not as practical if your roof is newer and in good shape
Improved insulation: Concrete tile roof keeps home cooler in summer and warmer in winter	Labor-intensive installation: Hundreds of small tiles and electrical connections mean installation must be done by specialized crews (cannot DIY)
Works with storage: Compatible with Tesla Powerwall batteries for backup power	Slightly lower panel efficiency per area: Tile format is a bit less efficient per square foot than top traditional panels, so you need sufficient roof area

Voltaic’s integrated solar roof is an excellent option for homeowners who want to go solar without sacrificing their home’s appearance. The pros are impressive: a sleek, all-in-one solar roof that looks like a luxury concrete tile roof, provides better insulation, and is engineered to withstand hurricanes, hail, and fires. The 25 year combined warranty and a network of certified installers give peace of mind that the system will be supported long-term. Voltaic tiles turn the entire roof into an energy producer, potentially increasing your home’s value and cutting utility bills over decades.

The main challenge for homeowners is the upfront investment, integrated solar roofs like Voltaic’s come at a premium price. You’re essentially paying for a new high end roof + solar system in one, so the upfront price can be significantly higher than that of a conventional solar panel retrofit. Voltaic’s roofs are relatively new to the market, so long-term data is limited; however, the underlying Ergosun technology has been successfully tested elsewhere.

What does Voltaic’s solar roof system include?

Voltaic’s flagship product is the ICON integrated solar roof tile system. Unlike companies that offer both panels and solar shingles, Voltaic focuses solely on building-integrated photovoltaic (BIPV) concrete tiles. Each Voltaic solar tile is a reinforced concrete tile with embedded high-efficiency solar cells. The tiles are about 11.7″ x 13.2″ (298 x 335 mm) in size, roughly the size of a standard roof tile. Each tile generates 17.5 watts (W) of power under standard conditions. In practical terms, about 10 Voltaic tiles cover one square meter of roof area and produce ~175 W of power in full sun. A typical 6 kW solar roof might use on the order of 340 tiles to reach the needed capacity, covering much of an average home’s roof.

Voltaic’s solar tiles use monocrystalline solar cells laminated with a proprietary DuPont™ Kapton® polymer film for durability. The solar cells are integrated into the concrete tile in a way that the tile lies flush on your roof with no bulky racks or panels on top of the roof surface. This means the finished install looks like an upscale concrete tile roof in either charcoal gray or terracotta color (terracotta is available by special order to match Spanish tile aesthetics). Because the solar functionality is built-in, there’s no roof clutter, a big selling point for homeowners in communities with strict HOA rules or who simply prefer a cleaner look.

Key performance specs: The Voltaic tiles have an efficiency of ~19.2%, which is comparable to many standard solar panels and even to CertainTeed’s solar shingles (≈19.85% efficient). The power output per tile (17.5W) is much smaller than a conventional solar panel (which might be ~400W), but remember you use many small tiles across the roof. The system’s temperature coefficient is around -0.45%/°C, meaning performance will drop slightly more in very high heat compared to top-tier panels (which are ~ -0.3%/°C). However, since the tiles are concrete, they have some thermal mass and are installed with an air gap and underlayment that provides ventilation. This helps dissipate heat and keep the system running efficiently even in hot climates.

Extreme weather design: A major advantage of Voltaic’s roof system is how robust it is as a roof. The tiles are made of high-strength concrete and interlock as part of the roof assembly. The system is Class A fire-rated (the highest fire resistance rating) and hurricane tested. In fact, Voltaic advertises that the roof is rated for winds up to 160-180 miles per hour, that covers even Category 5 hurricane-force winds. The tiles also carry a Class 4 impact rating, meaning they survived two-inch hail strikes at ~50+ mph in testing. The building-integrated design of Voltaic tiles helps limit wind exposure, providing an additional storm-resilient option for homeowners alongside traditional panel systems. This makes Voltaic’s system especially appealing for homeowners in hurricane-prone areas (e.g. coastal Florida) or hail prone regions. The fact that the solar tiles double as the roof surface also means there are no exposed roof shingles to be damaged underneath, the solar panels are your roof.

Roofing and installation: The ICON solar tiles are installed by trained roofing contractors in Voltaic’s certified network. The installation process is similar to putting in a new concrete tile roof, with the added step of connecting the tiles electrically. Voltaic tiles use a “double-batten” or cross-batten mounting system to allow running wiring underneath and to ensure water flows off properly. The tiles overlap and interlock like traditional tiles, and an advanced underlayment and flashing system keeps everything waterproof. According to Voltaic, the system preserves the roof’s integrity: instead of drilling brackets into your roof (which can create leak points in a concrete tile roof), the solar tiles adhere or fasten directly to the roof decking or base tiles without excessive penetrations. This approach means you get a brand new roof surface and shouldn’t need additional roofing beneath the solar tiles in active areas. In inactive areas (e.g. roof sections not getting solar tiles), matching concrete tiles are used so the roof looks uniform.

Voltaic offers a single integrated product, a concrete solar roofing tile system, which can be tailored to each home. You won’t find standard PV panels or separate solar shingle lines in their catalog, they are entirely focused on this integrated solar roof concept.

Voltaic vs. other solar roof options

How does Voltaic’s solar tile roof stack up against the other solar roofing products on the market, like the Tesla Solar Roof or GAF Timberline Solar shingles? The table below compares some key metrics of Voltaic and a few leading competitors in 2025:

Product	Power per Square Foot	Warranty	Approx. Cost
Voltaic Roof Tile (ICON)	16.3 W/sq ft	25-year product & power; includes workmanship if installed by certified contractor	~$4.00 - $7.00/W (installed)
Tesla Solar Roof	15.4 W/sq ft	25-year product and power warranty	~$1.80/W plus full roof replacement costs
GAF Timberline Solar	14.6 W/sq ft	25-year performance + manufacturing; 10-year workmanship	~$4.00 - $4.25/W (installed)
Luma Solar Roof	16.2 W/sq ft	25-year power (≥80% output); 5-year product	~$4.50/W (installed)
CertainTeed Solstice Shingle	16.1 W/sq ft	25-year power & product; 10-year 110 MPH wind warranty	~$3.00 - $6.00/W (estimated)
Suntegra Solar Tile	15.9 W/sq ft	25-year power; 10-year product warranty	~$4.00 - $6.00/W (installed)

Voltaic’s efficiency (19.2%) is right on par with CertainTeed (19.85%) and likely similar to Tesla’s (Tesla doesn’t publish efficiency, but it’s around 17-20% by most estimates). Durability is a strong point for Voltaic: its 160+ MPH wind rating and Class 4 hail resistance match or exceed most others. For comparison, Luma’s shingles are rated >200 MPH wind, and Tesla’s glass tiles are advertised to handle 1.75″ hail, so all high-end solar roofs aim for top durability. One area Voltaic shines is fire safety, not all solar shingle products achieve Class A fire rating for the entire roof system, but Voltaic’s concrete base gives it that Class A rating by default (Tesla’s glass tiles are also Class A).

Voltaic’s warranty offers a comprehensive 25-year warranty that covers both the product and power output (and by using a certified installer, labor/workmanship issues are covered for up to 25 years as well). This is on par with Tesla’s 25 year coverage and a notch better than Luma’s (which only gives 5 years on the product hardware). It’s clear that Voltaic is positioning its warranty to be competitive with the best in the industry, giving customers confidence that their investment will last.

Bottom line: Voltaic’s solar roof stands up well against its competitors on specs like efficiency and durability, and it offers one of the best warranties out there. Aesthetics and design appeal will depend on personal style and architectural context, but if you like the look of a seamless concrete tile roof, Voltaic arguably provides the most integrated, “invisible” solar look (even more than Tesla’s, which still has some shiny glass appearance). If you are looking for a concrete tile solar roof Voltaic is a very compelling option with cutting-edge design.

Does Voltaic offer a good solar warranty?

Yes, Voltaic’s warranty is one of its strong suits. The standard Voltaic warranty package includes 25-year coverage on the tiles and their power output, which is equivalent to the industry’s top offerings. In other words, Voltaic guarantees that your solar roof tiles will produce electricity at a specified performance level for 25 years (typically this means they’ll generate at least ~80% of their original output by year 25, as is standard for solar modules). It also guarantees the product quality for 25 years, protecting you against manufacturing defects or premature wear. This is double the length of many conventional solar panel product warranties (12 years is common for panels, though premium panels also offer 25 years now).

Because Voltaic Roof Tile is part of a larger, established roofing products company (Ergosun), you can expect the company to honor its warranties. They carry multiple third-party certifications (UL, IEC, building code compliance) which were necessary to get product approval, another indication of quality control. While Voltaic itself is new, the backing company has been developing these tiles for several years. Consumers should still do their own research on the company’s stability because a 25-year warranty is only as good as the company behind it. In this case, Voltaic/Ergosun appears to be well-funded and has partnerships in multiple regions.

How much do Voltaic Solar Roof Tiles cost?

An exact price for a Voltaic solar roof is hard to pin down without a specific quote, but you should be prepared for a significant investment. Voltaic’s product is marketed to “fashion-forward and luxury markets”, which implies it’s not aiming to be a budget option. While Voltaic hasn’t publicly released cost figures, we can infer from similar products and the scope of the project.

For context, traditional rooftop solar panels in the U.S. average about $2.50 - $3.50 per watt in 2025 (before incentives). Integrated solar roofs tend to cost much more because they include roofing material and specialized installation. Other solar shingle/tile systems often range around $4 to $6 per watt installed. For example, a Tesla Solar Roof that powers an average home (roughly 6-8 kW system) can end up costing around $90,000 - $100,000 in total. This figure includes tearing off the old roof and installing both the new solar tiles and non-solar glass tiles on the entire roof. GAF’s Timberline Solar shingles (which integrate with asphalt roofing) might cost between $40,000 to $100,000 depending on the home. Luma Solar roofs often end up $70k+ for a full installation.

Voltaic’s concrete solar tile roof will similarly require a full roof installation. If your home has a 2,000 square foot roof, you’ll be getting a brand new concrete tile roof (which alone could be $20k - $30k or more for high-quality tiles) plus the embedded solar tech. The solar capacity you need will dictate how many tiles are active solar tiles. It’s possible not every tile on the roof will have a solar cell (for instance, north-facing or shaded sides might use dummy concrete tiles), but you might still be paying for a uniform installation across the whole roof. Given the labor and materials, a ballpark could easily be $30,000 - $60,000+ for a Voltaic roof on a typical home, and it could rise higher for larger or complex roofs. This cost is aligned with the premium pricing of other BIPV systems.

It’s also worth noting the value-add of a solar roof: it is a new roof (with a long lifespan) and a solar generator in one. So part of the cost replaces what you’d spend on a new high-end roof anyway at some point. If your existing roof needs replacement soon, the math for Voltaic looks better than if your roof is brand new. Additionally, the energy savings over time will offset some cost. A properly sized solar roof can slash your electricity bills for 25+ years. Homes with solar have also been shown to sell for a premium in many markets, which may recoup some investment if you move.

Interested consumers should expect Voltaic solar roofs to be an expensive, premium home improvement, likely on par with Tesla’s Solar Roof in cost. Each project will vary, but don’t expect the cost to be similar to just adding a few panels; this is a whole roof renovation. Always get a detailed quote: Voltaic offers a concierge design consultation and custom proposal for interested homeowners. That proposal will show exactly how many tiles, what capacity, and the total price for your home. With incentives, many customers might find the long-term value compelling, especially if they were planning a roof upgrade regardless. Just go in with eyes open that this is a long-term investment in your home’s energy and structural infrastructure.

Finding the right installer for a Voltaic solar roof

If you decide to pursue a Voltaic solar tile roof, choosing a qualified installer is the most important next step. Installation of an integrated solar roof is more complex than a standard solar panel job, it involves roofing, wiring, and meeting building codes for both. Here are some tips to ensure you get the best installer for the job:

• Compare multiple quotes. Solar roofs are specialized, so you might only have one or two authorized installers in your region, but if you have options, get a couple of quotes. Ensure each quote outlines the scope: how many solar tiles, how many non-solar tiles, any structural enhancements needed for the weight, electrical work (inverters, Powerwall if you choose, etc.), and permit fees. Comparing will help you get the best price and also judge the knowledge of each installer. Just as with normal solar, sometimes quotes can vary significantly, don’t assume the first number is set in stone.

• Look for roofing experience. Ideally, the company should be a licensed roofing contractor as well as a solar installer (or a solar installer that subcontracts a roofer). Installing concrete tiles, flashing valleys, and ensuring waterproofing are crucial. Many of Voltaic’s partners are roofing companies that added solar expertise. You want someone who will treat your project as both a new roof installation and a solar installation.
  

• Verify their credentials and track record. Just as you would for any solar project, check how long the installer has been in business and read any customer reviews if available. A company with at least 5+ years of solar or roofing experience is preferable. Even if Voltaic itself is new, the contractor should have a solid history in construction. Don’t hesitate to ask for references or to see if they have installed any Voltaic systems (or similar BIPV systems) before.
  

• Ask about the installation process and timeline. A Voltaic roof install will likely take longer than a regular panel install. A good installer should explain the steps: removing old roofing (if applicable), laying down underlayment, installing the tiles section by section, electrical hookups, inspections, and so forth. You’ll want to know how long your roof will be exposed and how they protect your home during work. Professional crews will work efficiently to minimize downtime and ensure your roof is watertight each night.
  

• Ensure after-sales support. Once the roof is up, you may have questions on monitoring (Voltaic has an app coming for system monitoring ) or maintenance. The ideal installer will provide a handover package and be available for any issues. Given the 25-year warranty, also ask about their workmanship warranty (some installers might separately offer a labor guarantee, though if they’re certified, Voltaic covers it as discussed). It’s nice to know the company will service your system if, say, a tile or inverter needs replacement in 10 years.

By securing a reputable, experienced installer, you’ll set yourself up for a smooth installation and a solar roof that performs optimally. With the right team on the job, your Voltaic solar roof tile system could be powering your home (and turning heads in the neighborhood) for decades to come.
