This guide covers the currently available and newly emerging BiPV / roof integrated PV (RiPV) solar shingle options, their costs, availability in specific markets within the US, and pros and cons of each option.


The table below includes the cost info and availability details for the top four leading RiPV competitors:

Product Cost per sq.ft. Cost per watt* 2,750 sq.ft. roof
CertainTeed Apollo II Shingle $17.25 – $22.00 $6.40 – $8.00 $47,230 – $60,500
CertainTeed Apollo II Tile $20.88 – $27.37 $7.65 – $10.00 $57,420 – $75,281
Dow PowerHouse II) (Discontinued due to bankruptcy) $15.00 – $20.00 Est. $6.15 $41,250 – $55,000
SunTegra Shingle $15.52 – $17.4 $5.70 – $6.40 $42,694 – $47,850
SunTegra Tile $16.80 – $21.30 $6.16 – $7.81 $46,200 – $58,575
Tesla Solar Tile $32.00 – $42.00 $11.77-$15.40 $88,000 – $115,500

Note: the above figures are baseline costs (estimated). The actual costs can in some cases be up to 25% higher, depending on the particulars of the jobs including more complex roofs and/or in areas with high cost of living, and in major coastal cities.

All costs include what is known as BOS, or balance of system, costs. These include the connectors, wiring and electrical inverter required for the installation. They do not factor storage battery costs ($7,500 – $12,500 for most systems).

Below are further details of each product for comparison purposes:

CertainTeed Apollo II Shingles and Tiles

Of the current competitors in this growing field, CertainTeed was the first to introduce an integrated solar roofing product. It is now in its second generation and is available nationally.

Apollo Tile II Hero 2

These products use monocrystalline silicon solar photovoltaic cells, the most common technology in solar panels and RiPV products.

The Apollo II shingles and tiles attach directly to the roof deck rather than over existing roofing. Standard roofing nails are used. The solar field is then surrounded by shingles or tiles.

Apollo II shingles have a very low profile for use with asphalt shingles; tiles are slightly beefier to blend with flat concrete roofing tiles. Both products have 14 cells each with solar output of 60 watts.

The warranty covers materials for 10 years and solar output for 25 years. If you use a CertainTeed Credentialed Solar Installer (not required), installation workmanship is covered for 15 years, or 25 years if using a Master Installer. Expect to pay a premium of 10% to 25% for using a Credentialed or Master installer.

The wind warranty is 110mph for both products, but CertainTeed states in its literature that both products can be installed in high-wind zones where wind speeds reach 150mph. Due to this discrepancy, get the wind warranty in writing to know exactly what coverage you have.

Pros and Cons of Apollo II Shingles and Tiles

The shingles (15.4%) and tiles (16%) offer excellent conversion. They turn more solar into energy than most competitors. The tiles are tops in this class.

Installation is easy, since both products attach directly to the roof deck. This also eliminates the double cost of having roofing beneath and traditional solar panels on a rack above.

Aesthetics are good, but you have just two options. The materials are black, and they look like low-profile solar panels instead of traditional roofing material.

The conversion of power at 13.7% and 14.3% is lower than the typical 16% to 22% efficiency range achieved by monocrystalline solar panels, but that’s a shortcoming all RiPV products share to a greater or lesser extent. Their tight-to-the-roof design doesn’t allow airflow beneath the cells. This can cause overheating, which hurts efficiency.

Dow POWERHOUSE Solar Shingle

This product compares closely with the Apollo II and SunTegra shingles.

Dow put the POWERHOUSE shingle on the shelf in 2016. In March of 2018, RGS Energy reached a licensing agreement with Dow to manufacture the POWERHOUSE 3.0 shingle. RGS (Real Good Solar) has been an installer of solar equipment for four decades and has members of the original Dow team working on this product.

PowerHouse 3.0 BIPV solar tiles by RSG

Version 3.0 uses silicon solar cells, about 60 watts per shingle. The earlier POWERHOUSE shingles were copper indium gallium selenide (CIGS) panels, but that technology is too pricey to be competitive.

POWERHOUSE shingles install directly on the roof deck and are surrounded by standard asphalt shingles. RGS is requiring homeowners to use an installer certified to install POWERHOUSE.

RSG Update: Unfortunately, RSG had filed for bankruptcy in 2020.

Pros and Cons of POWERHOUSE 3.0 Solar Shingles

We anticipate the same advantages and disadvantages when compared with traditional solar panels as are found in the CertainTeed Apollo II products. Better looks with a lower profile than panels, but there is a distinct difference between the look of the solar shingles and the surrounding asphalt shingles.

In short, RSG POWERHOUSE 3.0 shingles are not as attractive as Tesla’s whole-roof shingle system (currently not a widely available product), but they are not nearly as costly either.

SunTegra Solar Shingles and Tiles

SunTegra products are available now. They offer similarities and differences to the competitors.

Like the Tesla, Apollo II and POWERHOUSE products, SunTegra is a two-in-one roof – solar energy production and roofing protection for your home.

SunTegra Shingles

SunTegra shingles are designed to blend well with asphalt shingles.

SunTegra Tiles

SunTegra Tiles are about the same thickness as flat concrete tiles, and wouldn’t look out of place with thick architectural asphalt shingles like Carriage House from CertainTeed.

Certainteed CH Stonegate-Gray Architectural Shingle Profile

SunTegra tiles and shingles are different and unique among these products in that they feature a built-in lower venting structure called TegraVent. It allows airflow beneath the monocrystalline silicon solar panels. This prevents them from overheating and losing efficiency.

The SunTegra shingles are up to 15.9% efficient, the best for shingles in this comparison. The 15% for tiles is better than most, though still below the low end of the 16% to 22% efficiency ragne that monocrystalline PV solar panels can achieve. SunTegra’s 130mph wind warranty is the best in this group.

Pros and Cons of SunTegra Solar Shingles

SunTegra has a slight cost advantage over CertainTeed and POWERHOUSE (discontinued due to bankruptcy). You’ll enjoy slightly better efficiency with SunTegra, especially tiles – more energy output per square foot means less solar tiles and shingles are needed to give you the kilowatts you want. The guaranteed wind rating is also higher than CertainTeed and RGS offer (discontinued due to bankruptcy).

The individual shingles and tiles are larger than the other brand’s products, so installation goes slightly faster.

The downside is the appearance of the shingles integrated with asphalt shingles. The TegraVent design makes this product slightly thicker and raises its profile slightly above the others. The best aesthetic is achieved when SunTegra tiles are paired with concrete tiles.

Tesla Solar

Tesla makes the premium product in this field. The Tesla solar roof is getting plenty of publicity, though now that roofs are being installed, not all of it is good. The aesthetics of the roof are superior to other BIPV options, but the cost is about double.

What’s different about Tesla is that it produces solar and non-solar tiles. Roofs on single-story homes average 35% to 40% solar tiles. The percentage is higher on multi-story homes.

Tesla tiles are hardened glass with excellent impact resistance. Solar tiles feature a silicon PV substrate. The tiles are offered in four styles: Smooth, textured, traditional barrel tile and slate.

The lifetime material warranty far surpasses the other products. Power generation coverage for 30 years is also the best in this class. Tesla includes a 30-year weather warranty against leaks.

Pros and Cons of Tesla Solar Roofs

These are the best-looking products available, designed to look like upscale contemporary roofing and not BIPV roofing. The four styles give you options to suit most homes. The warranty coverage is excellent too.

The major drawback is price. Since their efficiency rating is about the same, the payback time on a Tesla solar roof is about twice as long. It’s not a good value.

Note: Tesla solar tiles are not really a viable product as of yet. Only a handful of these roofs have been installed so far. Future product availability guidance is murky at best and we don’t know if we’ll see the market ready Tesla solar tiles any time soon.

Choosing a BiPV or RiPV Solar Roof

If you want a solar shingle roof now, then SunTegra and CertainTeed are your options. Of these, CertainTeed has a larger base of qualified installers across the country.

One point in SunTegra’s favor is the better wind warranty of 130mph. If you live in a high velocity hurricane zone (HVHZ), you’ll have more assurance with SunTegra.

The POWERHOUSE from Dow/RGS used to have one advantage that is worth considering. RGS (Real Good Solar) Energy has been fully immersed in the solar industry since the company started in 1978.

RGS Energy was a certified installer of the Dow POWERHOUSE 1.0 AND 2.0 shingles (discontinued due to bankruptcy). We think the company’s experience gave RGS an advantage when it came to proper design and installation of a BiPV system tailored to your home and energy needs.

As noted, the installation of POWERHOUSE roofs was expected to start in 2019, but alas, the new PowerHouse RSG venture has folded and declared bankruptcy in 2020.

When looks and not price is the determining factor, then a Tesla solar roof is the clear winner. However, there are a few notes of caution. Expect to wait well into 2022 and possibly beyond for a Tesla to really scale the installations of the new version of the Tesla Solar roof that has recently increased in price by 50%.

Early installations are going slow and we suspect Tesla is losing money because of the high labor costs. That could lead to a restructuring of the price. Perhaps the company will solve the installation issues it is having, but we’re taking a wait-and-see approach. 😉

  1. These BiPV setups used to be quite popular, but they can be a fire hazard due to the lack of proper cooling, which makes it really hard to insure in some markets. Make sure you check with your insurance and hire a contractor who 100% knows what they’re doing whenever you want to retrofit your roof with these systems. BTW, I do think these look way, way better then traditional PV installations.

  2. Thanks for this review it was very helpful. Have you also looked at Luma Solar roofing? They were featured in the 2011 State of the Union address. They have Metal roofing and Shingles, looks really nice. I’m not affiliated with them in any way other than looking at their product for potential purchase.
