When the Dow Chemical Company's announced that it was discontinuing manufacture of the Powerhouse solar shingle, some in the media began offering up obituaries for building-integrated photovoltaic (BIPV) technology. Then came Elon Musk's announcement that his Tesla venture was delving into the market - seemingly re-injecting life into the conversation - yet we at CertainTeed have strongly believed in the future of integrated solar since we began offering BIPV products in the late s. 

This article covers three reasons why homeowners continue to choose roof-integrated solar and why the BIPV market is poised for growth in the years ahead.

1. Solar shingles save time and money, using a single installation crew and a single product for roofing and solar energy production.
2. High-efficiency solar shingles can produce about as much energy as conventional, roof-mounted solar.
3. As solar installation prices continue to fall and homeowners grow more accustomed to owning PV systems instead of using third-party financing, differentiated solar products, like solar shingles, will have an opportunity to gain market share.

Recognizing BIPV’s full value

Before making a comparison between solar shingles and conventional solar panels, you have to know something about the condition of the homeowner’s roof. If the roof shingles are deteriorating and need replacement, it can be more cost effective to install solar shingles than to replace the roof and install roof-mounted solar.

There are other reasons why homeowners may prefer roof-integrated solar. Structural limitations could mean that traditional solar panels would compromise the integrity of the roof while lightweight solar shingles would not. Homeowners’ associations might favor the low profile of roof-integrated solar that blends in with neighboring homes, as might any homeowner with solar access on the front side of the home.

No two homes are exactly alike. Just as some residential solar projects use technology to mitigate the effects of shade on energy production, others use solar shingles where conventional solar panels would not be cost effective or may be altogether unfeasible.

Efficient and powerful

The biggest knock on other solar shingles has been that the thin-film solar cells they use produce energy with less efficiency than solar panels using crystalline silicon cells. This criticism cannot be applied to all BIPV products.

CertainTeed Solar uses crystalline silicon cells in the production of our Apollo II solar shingle and solar tile systems. And our manufacturing process is flexible enough to integrate new cell technologies as they offer better customer value.

When designing a PV system with solar shingles, the efficiency of the system is the same as the efficiency of each shingle. With roof-mounted solar, the need for spacing between modules means that system efficiency is lower than module efficiency. This doesn’t make a huge difference, but it’s worth keeping in mind when comparing roof-mounted solar and solar shingles.

BIPV’s time is coming

For years, companies operating throughout the solar value chain have been under intense price pressure, especially solar module manufacturers. The residential market in the US has been particularly competitive because so many projects are owned by tax equity investors who favor low prices and a swift return on investment.

As system prices continue to fall and homeowners take advantage of loan financing to own solar projects themselves, the market is likely to see more demand for premium solar module features that provide better aesthetics, durability, and overall quality.

CertainTeed is North America’s leader in sustainable building products, bringing years of experience to develop a solar roofing system that delivers energy and long-term protection for the home. Homeowners choose our solar shingles because of our unrelenting commitment to their long-term success.

At CertainTeed Solar, we’ve built a business around the solar shingle backed by a nationwide network of builders and distributors and an extensive warranty covering the product, installation workmanship, and solar energy production. The product will continue to be available far into the future.

Solar shingle key points:

• Solar shingles provide the same function as traditional solar panels but look like standard roofing materials.

• The cost of solar shingles is much higher than standard panels for systems with a similar capacity.

• Many tax credits and other solar incentives can also be applied to solar roofing setups, helping bring down the upfront cost.

There have been major advances in the efficiency and durability of solar panels in recent years, but we’ve also seen breakthroughs in how they look, too. Solar shingles work just like the large panels that mount onto rooftops, but they are similar enough in appearance to standard asphalt shingles that they can blend right in.

In this article, we take a look at what solar shingles are, how they’re made, and how they work. We also examine how they compare to traditional solar panels in a few key ways to help you decide if they’re the right solar energy technology for your home.

What are solar shingles, and how do they work?

Solar shingles are photovoltaic roofing materials that look like standard asphalt shingles but generate electricity like solar panels. They blend into home design and convert sunlight into usable energy using embedded PV cells, making them ideal for new builds or HOA-restricted homes.

Photovoltaic (PV) shingles are constructed by assembling PV cells into small, shingle-shaped modules that replace or integrate with conventional roofing materials. These solar panels work by absorbing sunlight and converting it into direct current (DC) electricity. The electricity is then passed through an inverter, which converts it into alternating current (AC) for use in residential applications.

Most modern solar shingles use different types of panel technology:

• Monocrystalline cells  

• Polycrystalline cells

• Thin-film panels

What’s appealing about solar shingle design?

Here’s why solar shingles appeal to homeowners:

• Design-focused: Resemble standard roof shingles

• Low-profile: Avoid bulky panel appearance

• Aesthetic integration: Blend into residential architecture

• Visual value: Preserve a home’s overall design integrity

For many homeowners, the look of conventional solar systems is a hesitation point, especially in communities where HOAs or local regulations restrict solar panel placement or installation. Solar shingles address this concern by providing access to solar energy without the visual impact of traditional rooftop arrays, making them a preferred option for aesthetically sensitive environments.

What’s involved in solar shingle installation?

Although solar shingles typically consist of more individual components than traditional solar panels, many types are easier to install since they don’t require solar racking or additional infrastructure. Instead, solar shingles are designed to be mounted directly onto the roof surface, similar to how asphalt shingles are applied, which simplifies installation.

In many cases, homeowners can install solar shingles alongside standard roofing materials without needing to cover the entire roof, preserving both function and visual consistency. 

However, some systems, like the Tesla Solar Roof, use a proprietary mounting approach that requires removing and replacing the existing roof, making installation more complex and potentially costlier.

How do solar shingles compare to traditional panels?

Solar shingles and traditional panels both generate electricity from sunlight. Traditional panels are more efficient and cost-effective, while solar shingles offer superior aesthetics and roof integration. Panels are ideal for retrofits, whereas shingles suit new builds or HOA-restricted properties.

Which companies manufacture solar shingles?

Several companies manufacture solar shingles. Tesla offers the Tesla Solar Roof. GAF Energy produces Timberline Solar shingles. CertainTeed installs Apollo II shingles. Luma and SunTegra also create integrated solar roof tiles for residential use.

How long do solar shingles last?

In general, solar shingles have a similar estimated lifetime to the traditional solar panel lifespan of 25 to 30 years. This long working life means that they can provide a strong return on investment in the form of energy savings. However, solar panels may last a bit longer on average because it's easier to replace your roof material with panels compared to shingles.

Overall, solar panels are worth it for most homeowners who get at least 4 hours of average peak sun and have higher-than-average electricity bills.

Like other panels, solar shingles will experience a loss in efficiency over time. Homeowners can expect a similar decrease in efficiency of about 0.5% to 1% per year.

How do you maintain solar shingles?

Photovoltaic shingles aren’t likely to need as much maintenance as traditional panels due to having less racking and other infrastructure. However, shingles should still be cleaned regularly to maximize solar efficiency. It’s also important to periodically check for debris that may be covering up photovoltaic cells and reducing the amount of light that reaches them.

How much do solar shingles cost?

According to data from Angi, the average cost of solar shingles ranges from $21 to $25 per square foot, or an average of around $35,000 for a standard residential installation. The average cost of a 5 kW standard panel setup is $17,823 for comparison.

The most notable downside of solar shingles is their cost. Even at their least expensive, a solar array using photovoltaic shingles can easily cost more than twice the cost of standard solar panels with the same capacity.

Solar shingle costs can also go much higher. In recent years, some people have reported quotes of over $200,000 for a Tesla Solar Roof, for example. Ultimately, with fewer competitors in the market, pricing for solar shingles is less standardized than traditional solar panels, making it even more important to get multiple estimates.

Are there incentives for solar shingles?

The good news is that many of the same government incentives for solar panels apply to solar shingles as well. That means that you’ll likely pay substantially less than the initial price tag.

Homeowners in the United States who install solar shingles are eligible for a 30% tax credit through the Residential Clean Energy Credit (RCEC). Many states and even some municipalities also offer rebates and tax credits for installing a solar energy setup that includes using photovoltaic shingles. In the private sector, some energy providers also offer rebates and incentives that can bring down the initial cost of installing solar shingles.

What’s the bottom line on solar shingles?

Solar shingles are an expensive way to access clean, renewable solar energy for your home compared to traditional panels. However, they have the unique advantage of integrating with the design of your home, enabling people who live with strict HOA regulations or who don’t want the bulky look of traditional panels to switch to solar. That aesthetic difference could also increase the value they add to your home compared to regular panels.

The bottom line is that solar shingles are still a bit of a luxury among your options for a solar array. But if you can afford the difference in cost, they provide an attractive, elegant solution with few downsides beyond the price tag.
