Like regular roof shingles, solar shingles protect your home from the weather and other elements. These shingles are not only energy-efficient, but they also offer a more attractive aesthetic to a home than do the large, bulky panels normally associated with solar-powered energy.

Solar Roof Shingles vs. Solar Roof Panels

Solar shingles work in a similar way to solar panels&#;they both absorb the sun&#;s rays, converting the light to thermal or electrical energy. However, there are a few important differences between solar panels and shingles that you should know about when determining your home&#;s solar energy needs:

Size

Solar shingles are about the same size as traditional roofing shingles, with the average size being about 12 inches wide by 86 inches long, and weighing about 13 pounds per square foot. The thin tiles are less than an inch in thickness. It takes about 350 tiles to complete a typical solar roof installation.

Materials

Solar shingles are typically made from copper indium gallium selenide, which is what allows them to be so flexible and thin. This semiconductor is an ideal material as it results in a high conversion efficiency rate, which is about 10% to 12% on average. Some shingles, instead, use monocrystalline silicon, which is also used to fabricate computer chips. While these are more expensive, they are worth the extra price as they have a higher efficiency rate of around 15% to 20%.

Output

As the primary goal is to lower energy costs, this is a major consideration with solar installation. The majority of shingles will produce anywhere between 13 and 63 watts of power. The number of tiles in a typical home roof installation can lower the utility bill by 40% to 70%; by adding more tiles, you can increase the energy output.

While both solar shingles and solar panels convert the sun&#;s rays into energy, there are a number of differences that will help you decide between the two options:

Appearance

Since solar shingles blend right into the roofing materials, such as concrete or asphalt, many prefer this aesthetic rather than large black panels attached to the roof. In general, solar shingles create a sleeker aesthetic than do bulky solar panels, particularly since only parts of the roof, like the edging, might be covered in shingles to be efficient.

Service Life

Both solar panels and shingles have long life spans, typically upwards of 20 years. However, the longevity of solar shingles varies by the manufacturer and the installation. Warranties also vary; when you purchase solar shingles, be sure that you note the difference between power warranties. Solar shingle warranties can last for a couple of decades based on their production, while durability warranties that cover the shingles themselves can span the lifetime of the home.

Efficiency

Solar shingles are outshined by panels in terms of efficiency for a number of reasons. While solar panels can be adjusted as needed to achieve the best angle to capture the sun&#;s rays, shingles stay in the same place as they were first installed. You can always add more shingles to the roof to harness more energy, but as with all home improvement projects, more materials mean more money.

Installation

Solar shingles can take as much as a week to install&#;and that&#;s if your existing roof is in good shape. If you are building or redoing your roof before adding solar shingles, it can take even longer. Some solar tile manufacturers, like Tesla, will take two or more weeks to install.
This is in sharp comparison to solar panels, which can be installed within a day.

Durability

Solar shingles have one major advantage to panels: They are more durable. Unlike panels, which sit atop the roof, solar roof tiles are actually part of the roof. As such, they are more resilient and can stand up to harsh weather conditions and fallen debris. Additionally, solar shingles are fire-resistant, a feature that is not inherent in solar panels. (It should be noted, however, that the risk for fire with solar panels is very low.)

Cost

Solar shingles can be on the pricier side depending on how much square footage you need to cover and which types you&#;d like to get. It&#;s important to understand your budget before opting into a solar shingle project.

Solar Shingles Cost

Solar shingles typically cost more than solar panels because of the amount of materials needed for installation. The average price of solar roof tiles ranges from $15,000 to $20,000, but Tesla shingles could cost more than $70,000, along with a lengthy installation period. However, the ultimate cost of solar shingles depends on the size of the roof, the energy needs of your household and the manufacturer and installer of the shingles you have chosen. You can compare this to the cost of solar panels here.

Solar Shingles Cost Per Square Foot

When considering the installation of solar shingles, it&#;s important to understand the costs associated with this innovative roofing solution. Solar shingles not only provide the functionality of traditional roofing materials but also generate electricity, offering long-term savings on energy bills. The price per square foot for solar shingles can vary depending on factors such as the brand, roof pitch and installation complexity. However, the average cost per square foot for solar shingles typically ranges from $21 to $25.

Below is a table that illustrates the average total cost of solar shingles for different roof sizes, based on the average price per square foot:

Solar Shingles: Everything You Need To Know

Solar power is increasingly popular as a reliable and renewable energy source. Advances in technology have made solar energy conversion more accessible and affordable. With Hover, explore the unique features of solar shingles, their benefits and drawbacks, and the top brands available on the market today.

What are solar shingles?

Solar shingles, also known as Building-Integrated Photovoltaics (BIPV), represent a cutting-edge innovation in the realm of renewable energy. They are designed to mimic the appearance of traditional roofing materials while simultaneously harnessing solar energy. Unlike conventional solar panels that are installed on top of existing roofing, solar shingles are integrated directly into the roof structure. This dual functionality means that they not only provide the same protective qualities as regular shingles but also generate electricity from sunlight.

Solar shingles come in various designs and materials, aiming to blend seamlessly with traditional roofing materials such as asphalt or slate. This integration helps maintain the aesthetic appeal of a home, making solar energy accessible without compromising on visual appearance. The design of solar shingles allows them to function as a part of the roofing system, contributing to a more cohesive look compared to the bulkier traditional solar panels.

Overall, solar shingles offer a modern approach to sustainable energy solutions, merging functionality with design to create an innovative roofing option.

How do solar shingles work?

Solar shingles operate on principles similar to those of traditional solar panels, but their integration into roofing materials offers a more streamlined solution. At the core of solar shingles are photovoltaic (PV) cells, which capture sunlight and convert it into electricity. Here&#;s a step-by-step breakdown of how solar shingles generate power:

Sunlight absorption: The photovoltaic cells embedded in the shingles absorb sunlight. This light energy excites the electrons in the cells, creating an electric charge.
Electricity production: As the electrons move, they create a flow of electric current. This process generates direct current (DC) electricity.
Electricity conversion: The DC electricity generated by the solar shingles is then directed to an inverter. The inverter converts this DC power into alternating current (AC) electricity, which is the type used by household appliances and the electrical grid.
Distribution: Once converted to AC power, the electricity is either used directly by the home or fed into the grid, depending on the system&#;s configuration.

Solar shingles integrate these components into a single, unified roofing material. This design not only allows for energy generation but also maintains the protective and aesthetic functions of traditional roofing.

Solar shingles vs solar panels -- which is better?

When considering solar energy solutions, it&#;s essential to compare solar shingles and traditional solar panels. Each option has its unique features, benefits, and drawbacks:
