Solar Shingles: Pros, Cons, How to Choose

Solar shingles are roof shingles made of photovoltaic (PV) cells, the same electricity-generating material found on solar panels^[0]

The total price for installing solar shingles typically ranges from about $35,000 to $75,000, making them a more expensive option than solar panels. But they’re a durable and attractive alternative to solar panels, and an appealing choice for many.

While solar panels are mounted on your roof (or on your property), solar shingles function as your roof, providing shelter from the elements and producing solar electricity. Here’s how these two technologies stack up.

Solar panels use an older technology and are less expensive to purchase upfront than solar shingles. If your roof is in good condition, solar panels might be a more cost-effective option. However, if you’re planning to replace your roof anyway, solar shingles might make more sense.

Solar shingles are designed to look like standard roofing materials, while solar panels are engineered to capture maximum sunlight. Your choice depends on whether you’re more concerned with getting the most efficient system possible, or stronger curb appeal.

Solar shingles only work with tilted or sloped roofs, so if you’ve got a flat roof, they’re not an option. Solar panels, on the other hand, are compatible with all roof types — and they can also be installed on the ground.

While both solutions generate solar energy, solar shingles typically aren’t as efficient as solar panels because there’s no air flow under them. Because of this, they get hotter and produce energy at a lower rate. Unlike solar panels, which can be positioned to catch the most sunlight, solar shingles are fixed and have to be positioned as your regular roof shingles would. Depending on the orientation of your roof, this may also result in less than maximum potential efficiency.

Both technologies are designed to last for about 25 to 30 years on average^[0]

There are two main types of solar shingles:

• CIGS (copper-indium-gallium-selenide) solar shingles. These shingles use more recently developed thin-film technology to generate home solar power. They can also be made into more flexible and lighter shingles to blend into existing or new roofs.

• Silicon solar shingles. These rigid solar shingles are more like traditional solar panels and are proportioned to fit with conventional roofing materials.

Some major providers of solar shingles include:

Luma Solar says it’s the first company to develop rooftop solar shingles in North America. Designed with hurricane-force winds in mind, these shingles can withstand winds of 200 mph and higher. The company offers a power warranty of 25 years and a limited lifetime shingle warranty.

SunTegra’s solar shingles have excellent ratings for weather conditions, including snow, wind and fire. The company also offers a limited product warranty of 10 years and a 25-year limited power warranty.

Tesla’s fully integrated solar roof shingles are designed to withstand fire, high winds and hail. They come with a power and tile warranty for 25 years.

CertainTeed’s shingles can withstand winds of up to 110 mph and are rated for installation in any wind zone, including Florida’s hurricane zone. It offers a 25-year warranty.

Here are some factors all prospective buyers can consider when shopping for solar shingles:

• Appearance. Look for shingles that go well with your home. You can find solar shingles in styles that range from modern to traditional, so there should be something out there that suits your house.

• Budget. You’ll need to find a solution that you can afford. When considering the financial impact of this decision, research possible tax incentives that could offset your upfront costs, and factor in projected energy savings over the coming years.

• Suitability of your roof. Evaluate your roof’s orientation, size, shape and amount of sun it receives to make sure you’d generate enough electric power from solar shingles to make your investment worthwhile.

• Energy requirements. Calculate your home’s energy usage to make sure you select a solar shingle system that’s sufficient to meet or offset your energy consumption without being too powerful for your needs.

• Efficiency ratings. Look for the most energy-efficient shingles within your budget to get the best return on your investment.

• Provider. Choose a reputable manufacturer, known for a high-quality, durable product that comes with solid warranty protection.
