CertainTeed solar shingles: compare the original solar roof to other options for your home

Reading Time: 4 minutes

Before Elon Musk shook up the home solar power industry with the Tesla solar roof, homeowners and businesses were talking about solar shingles. The current leader in solar shingles is CertainTeed, whose solar roof products can be integrated as part of your existing roof.

What are CertainTeed solar shingles, and how do they work?

Solar shingles, also known as “building-integrated photovoltaics” (BIPV), are roof-shingle sized solar panels. CertainTeed’s solar roofing product is made of the same solar technology as traditional solar panels – monocrystalline solar photovoltaic cells.

However, unlike traditional solar panel systems, which are affixed to the roof with a racking system, CertainTeed solar shingles are installed as an integrated part of your existing roof. The result is a low profile, unobtrusive solar energy system that sits flush with your roof tiles.

CertainTeed offers two solar shingle options: the Apollo II system and the Apollo Tile II. Both options provide the same power production – 14 solar cells for a total of 60 watts. The Apollo II system is designed to integrate with asphalt shingle roofs, while the Apollo Tile II is designed to suit roofs with concrete tiles.

How CertainTeed solar shingles compare to other solar options

Solar shingles offer a sleek, low profile solar option for many homes, but they may or may not be the perfect fit for your home. Here’s how they compare to traditional solar panels, as well as new solar roofing options like Tesla and Forward Labs’ solar roofing options.


CertainTeed solar shingles are based on the same fundamental solar technology as both standard solar PV panels and other solar roofing options: silicon solar photovoltaic cells. However, because of the nature of the product, CertainTeed’s solar shingles will produce less electricity than a similarly sized roof-mounted solar panel system.

According to CertainTeed’s product specifications, the Apollo II system has a conversion efficiency of 15.4%, and the Apollo Tile II system has a conversion efficiency of 16%. These statistics are on the low end for standard solar panels, which can offer efficiency ratings between 16% and 20% on average.

This is due to the fact that building-integrated solar panels don’t have air circulating underneath the solar cells to cool them. Like other electronic equipment, solar panels can overheat. While this style of installation does create a low-profile look, it also comes with lower electricity production.

It’s worth noting that both Forward Labs and Tesla’s solar roof products likely have similar efficiency losses because of how they are installed. However, neither company has released sufficiently detailed information on their solar roof efficiency.

Installation process

A traditional solar panel installation can be completed in a matter of hours. (In fact, you can watch a full installation happen over the course of a few hours in EnergySage’s time-lapse video included below) The process is simple: workers install the brackets and mounting system for the solar panels, and then connect the solar panels to the framework.

The installation process for CertainTeed solar shingles is more complex. According to the company, their shingles “function both as the roof covering and the solar PV collector.” However, unlike Tesla and Forward Labs’ solar roofing options, CertainTeed’s offering is designed to work with your existing roof, which means that it doesn’t require a full roof replacement.


If your primary concern is finding a truly “hidden” solar power installation, Tesla and Forward Labs are the only companies that offer a “solar roof” with solar cells that are invisible from ground level. However, because CertainTeed shingles are integrated into the roof, rather than installed on top of it, they are much lower profile than a standard solar panel system.


In the world of home solar, the lowest cost option – and the one that offers the greatest long-term savings – will most certainly be a standard solar panel system. The average cost of solar in 2020 is $2.96/Watt, and the average EnergySage customer can cover over 95 percent of their electric bill with their solar panel system.

By comparison, EnergySage analyzed Forward Labs solar roofing data and found that their product cost approximately $4.90/Watt, including the cost of non-solar roofing materials needed to complete the installation. The same analysis found that Tesla solar roof pricing is close to $6.40/Watt.

Certainteed doesn’t make specific pricing information available on their website. However, the complexity of installation means that we can expect their system cost to fall somewhere between a standard solar system and a full solar roof.


According to CertainTeed’s website, the Apollo II and Apollo Tile II products both come with the following warranties:

  • Installation & workmanship: 25 years
  • Inverter & other components: 10 years
  • Power output: 25 years
  • Wind warranty: 10 years

These warranties are comparable to other options within the solar industry. Forward Labs and Tesla’s warranties are stronger – both companies offer 30-year warranties for power production and weatherization. Tesla also offers an “infinite” warranty that applies to their physical roof tiles.


Availability is an area where CertainTeed stands out from other solar roofing options. Both Tesla’s solar roof and Forward Labs’ product offering are only available in select test markets in California, with no indication of when they will be rolled out in other parts of the country. CertainTeed’s product is currently available across the country through its network of installers.

Solar shingles offer a nice compromise between the aesthetically pleasing, costly solar roof and a standard solar panel system. However, the aesthetic benefits of a CertainTeed installation come with some compromises on electricity production and cost. In many cases, a standard solar panel system is a much more cost-effective option for your home. The average EnergySage customer with a solar panel system breaks even on their solar investment in just seven years.

If you’re considering a solar roof, CertainTeed solar shingles, or standard rooftop panels, comparing all of your options can help you determine the relative costs and benefits of going solar.

    Hello Addison,
    would it be possible to share the name of the contractor you’ve used? I’d like to do a similar project to my house in Virginia’s Hampton Roads area.
    Thank you!

    I had a 9kW Certainteed Apollo II system installed in my northern Virginia home approximately 18 months ago. It was difficult finding a local installer or even getting a referral from Certainteed. Fortunately, after a few calls and emails, first to Certainteeds Solar; then to Certainteeds corporate; and finally to Certainteeds parent company St. Gobain, I was rewarded with a referral for a local roofing contractor and solar installation combine. They were new to the product but received lots of design and installation assistance from Certainteed. The final installation is great, and I haven’t paid an electric bill since. The road was long and a bit bumpy, but the trip was worth it.

    I tried many times to get CertainTeed Solar Shingles installed on my house in Dauphin County, Pennsylvania. It has been impossible to even get anyone to come and do the job. I visited Century Contractors in Elizabethtown last Autumn and told them I’d like to have the job done before winter. They still haven’t shown up. GOOD LUCK buying these or finding anyone interested in taking the job.
