SunTegra Solar Roof Tiles & Shingles Cost – The Ultimate Guide

Solar roof shingles can be an attractive option for homeowners who don’t like the appearance of conventional solar panels. Unlike the traditional PV installations where panels are mounted on top of the roof, solar shingles and tiles become part of the roof itself.

Suntegra integrated solar tiles on a roof

As you might guess from the name, these are roof shingles with built-in photovoltaic cells, which means you don’t need to install two separate components. SunTegra is one of the leading solar tile roof providers in the US, and their products can easily integrate with both asphalt shingle and concrete tile roofs.

SunTegra was founded in 2013, and the company was originally called Integrated Solar Technology (IST). SunTegra was founded by Oliver Koehler, who had already accumulated 15 years of experience in the solar power industry.

As of 2022, SunTegra has expanded to Canada and Mexico, and the company offers two main products: solar shingles and solar tiles. Each product line has different dimensions and specifications, adapting to many different types of roofs.

SunTegra is also working on new solar products for gardens and patios, which will become available in the near future. They are also developing solar products for building facades and other vertical surfaces, which will also be available for commercial and community buildings.

Suntegra Solar Shingles and Solar Tiles: What Is the Difference?

If you visit the SunTegra website, you will notice they offer two main products: solar tiles and solar shingles. Each product is designed for different types of roofs, and below we will provide a detailed comparison.

Both SunTegra products use monocrystalline solar cells, achieving a rather high electricity output throughout their service life.

SunTegra Solar Tiles are designed for concrete or clay tile roofs, and they can be installed just like traditional concrete tiles. You can use them in a new construction project, or you can upgrade an existing concrete or clay tile roof without having to replace all the tiles. SunTegra solar tiles are suitable not only for homes, but also for commercial buildings and carports.

SunTegra Solar Shingles are designed to replace asphalt shingles, but they are also compatible with other low-profile roofing materials. They use 50% fewer parts than a traditional solar panel system, and they can also be installed twice as fast. SunTegra shingles have a lightweight design, and they have built-in wiring to speed up their installation.

The following table compares the features and specifications of both solar roof products from SunTegra. Keep in mind that they are designed for different types of roofs, and they are not competing products.

Both solar tiles and shingles can be used for partial upgrades, meaning you can go solar without having to worry about the expense associated with completely replacing the existing roof.

The SunTegra solar shingles are slightly larger than the solar tiles, while having higher wattages and efficiency ratings. However, both products offer the same quality and durability, and their adaptable design that integrates with new and existing roofs.

You may have noticed that traditional solar panels with monocrystalline cells often have efficiency ratings above 20%. This happens because solar panels are separated from the roof by a racking system: more air can flow below them, and the cooling effect has a positive impact on their energy conversion efficiency.

On the other hand, solar tiles and shingles are installed flat on the roof. This limits the cooling effect of air movement, and their efficiency is lower as a result.

To compensate for the lower efficiency of solar tiles and shingles, you can simply cover a larger roof area to achieve a higher wattage. You should identify the roof sections that get the most sunshine throughout the year, since this will maximize the electricity output of each solar shingle (the same principle applies for traditional solar panels). Avoiding shaded areas is also critical, or your electricity output will be drastically reduced.

SunTegra Solar Roof Tiles and Shingles: Space Requirements

If you’re considering solar tiles or shingles for your roof, you might be wondering how much area must be covered to generate electricity for your home. An accurate calculation is only possible with a professional assessment, but we can get an idea of space requirements with a quick estimate.

  • Let’s assume you need to install 8 kilowatts to generate enough electricity for your home, and we will estimate the area you must cover with SunTegra solar tiles and shingles.
  • We will also compare these values with an area needed to reach 8 kW of capacity with traditional solar panels.

Considering a 360W monocrystalline solar panel that measures 65” x 40”, you would need 23 of them to reach 8 kW. Since each solar panel has an area of 18.06 square feet, you will need to cover 416 square feet of roof space.

If you have a tile roof, you can use the 70W SunTegra solar tiles. You need 115 tiles to reach a power output of 8 kW, and each of them has an exposed area of 52 in x 13.75 in, equivalent to 4.97 sq.ft. This means the total area covered by SunTegra solar tiles will be around 571 square feet, which is 37% more than the space needed by solar panels.

On the other hand, if you have an asphalt shingle roof, you can use the 114W SunTegra solar shingles. You would need 71 to reach 8 kW, each solar shingle has an exposed area of 52.0625 in x 19.75 in (7.14 sq.ft.), and you would cover 507 square feet of roof space. This installation only uses 22% more area than a traditional solar panel system.

SunTegra Shingles

Solar panels result in a more compact PV system, but also keep in mind that their installation is more difficult. Remember that SunTegra solar tiles and shingles can be installed in half the time needed by solar PV modules with traditional racking, and they also use 50% fewer parts.

Also keep in mind that residential solar panels are much heavier, with a typical weight of 40-50 lb., which makes them more difficult to handle. On the other hand, SunTegra solar tiles and shingles only weigh 15 lb. and 18 lb., respectively.

Do SunTegra Solar Tiles and Shingles Have a Good Warranty?

As you can see in their technical specifications, both SunTegra products have the same warranty conditions: a 10-year product warranty and a 25-year power output warranty.

  • The SunTegra product warranty is at the lower end of the typical coverage period for solar panels, which ranges from 10 to 25 years depending on the brand and model.
  • The SunTegra power output warranty has the same coverage period offered by most solar panel manufacturers, which is also 25 years.
  • You can find some solar panels with a 30-year power output warranty, but most models come with a 25-year coverage.

Note that product warranties and power output warranties have terms and conditions. To keep these warranties intact, the best recommendation is getting in touch with a qualified solar roof installer. A deficient installation will void the warranty of solar tiles and shingles, while increasing the risk of electrical faults and fire.

How Does SunTegra Compare with Other Solar Roof Providers?

SunTegra is a quality brand that offers two main product lines, covering a wide variety of roof designs. Their solar tiles are available for homeowners with concrete tile roofs, while their solar shingles are designed to replace asphalt shingles and other low-profile materials.

Unlike solar panel systems, which have predictable pricing, the installation costs of solar roofs can vary a lot from home to home. However, EnergySage (somewhat dated information, so we tweaked it with our own estimates) has analyzed installation costs for some leading solar roof brands, estimating average prices in each case:

  • Tesla solar roof: $6.40 to $8.50 per watt (estimated)
  • Forward Labs solar roof: $4.90 to $5.90 per watt (estimated)
  • SunTegra solar shingles: $4.65 to $5.60 per watt (estimated)

For comparison, keep in mind that traditional solar panel systems normally cost around $3.06 per watt before the incentives. SunTegra has a cost advantage over competing products, which means you can get a quicker payback period and a higher ROI.

Another notable solar roof brand offering similar pricing is Luma Solar: when used for partial upgrades in existing roofs, installed costs of around $5.00 to $6.00 per watt (estimated) are possible.

SunTegra and Luma Solar both offer a design that can be used for partial roof upgrades. In other words, there is no need to replace your entire roof: you can simply install the exact number of solar tiles or shingles needed to power your home.

Tesla and Forward Labs only offer complete roof replacements, which results in a more expensive project. They use a combination of photovoltaic and traditional roof shingles with identical appearance, making the solar power system completely invisible.

If you’re only interested in solar power, a partial roof upgrade with SunTegra or Luma Solar shingles makes more sense financially. However, a complete solar roof can also be cost-effective if your existing roof requires complete a replacement.
