As photovoltaic technology becomes more modernized, researchers are beginning to develop alternatives to the traditional solar panel. Solar shingles are a recent addition to the expanding line-up of new PV technologies. Solar shingles and roof tiles are intended to replace normal roofing materials with roof shingles that generate electricity. They still function as roofing materials, being fire resistant and providing protection during storms. They cost more compared to traditional solar panels, but provide the same power output. Some are opting to switch to solar shingles simply for the aesthetics, as the low profile and simple design can add a nice modern touch to a home, and they serve as an alternative for people who would want to hide solar panels if they got them. A major deterrent for installing Teslas solar roof tiles is that they necessitate the complete replacement of the roof, which adds to the cost of installation.
Solar roof tiles are photovoltaics that integrated into the roof of your home. They are designed to look and act like traditional roofing materials, like asphalt or slate, while simultaneously generating power from the sun. They are part of a group of PV modules called building-integrated photovoltaics, or BIPD, a class of PVs that are built into the architecture of a structure.
Solar shingles first became commercially available in , and the market today has grown to encompass several companies and manufacturers. Tesla is the most well-known provider of solar roof tiles, though other companies like Luma, SunTegra, and CertainTeed offer them as well.
Solar shingles work just like traditional solar panels, except the individual modules are much smaller. Sunlight strikes the solar tiles, and the semiconductor material converts light energy into electricity via a chemical process. The electricity is then used to power your home, either directly, or via a generator or system of battery storage.
The average size of a solar roof tile is 12 in x 86 in (300mm x mm), and each solar roof tile can produce anywhere between 50 to 115 watts. Whereas early solar tile manufacturers used flexible CIGS as a semiconductor, more companies today are utilizing crystalline silicon solar cells. This means they can achieve higher efficiencies and be more competitive with traditional solar panels.
Solar shingles come in different types. Some can be applied directly onto existing roof tiles, while others replace the roof completely. Some are made with flexible semiconductor materials, while others are multi-layered and use traditional c-Si solar cells. Since not every part of the roof of a house faces the sun, solar installers might only place solar roof tiles where they will achieve the highest efficiency, while using similarly designed non-solar roof tiles where the sunlight doesnt shine, as well as on the perimeters of the roof.
Solar shingles tend to be quite expensive. On average, they can cost between $3.80 to $9.00 per watt. The price depends on the manufacturer, system size, and type of solar tile. Installation costs can also be a huge additive, as solar shingles that require a complete roof replacement cost much more than those which are simply layered over existing roof tiles. Although they are expensive, some states offer tax incentives for solar installations, and you can also still take advantage of net metering with solar shingles, just like your would traditional solar panels.
Its important to remember that youre not just getting a PV system, but a roofing material as well. Solar roof tiles have proven to be quite durable, being able to withstand strong winds and hailstorms. Some manufacturers claim that their solar roof tiles are stronger than traditional roof tiles.
Some homes might not be suitable with solar roof tiles. Those who already have expensive roofing materials might see it as an extra cost. Many solar shingles require completely removing the old roof and having it replaced, which can put off many homeowners. Solar roof tiles are best installed on homes that are still being built, where the owner has complete control over the design and building materials of the home.
Many like solar roof tiles simply for the aesthetic value. They have a dark color and a shiny, sleek look. Some might see the switch as a worthy investment, considering they get a sleek new roof along with a reduced energy bill.
The major difference between solar shingles and solar panels are the aesthetics and the price. Solar shingles are more appealing to the eye. The sleek look adds a look of modernity. They blend in better with the home, and passersby often cant tell that the house even has an installed PV system. Granted, solar tiles are still limited in styles. They all tend to have the same look; dark in color and completely flat. Tesla has only recently come out with new designs, like their Tuscan-inspired roof tiles, which have a dusty brown color and are shaped more like traditional roof shingles. Solar shingles also lack many of the extras required with a solar array, as the mounting racks, brackets, and external wiring are absent.
Solar panels are cheaper to install, mainly because they dont require a complete replacement of the roof. In many cases, installing both solar panels and new non-solar roofing separately can cost less than an entire solar roof tile installation. Where installing solar panels can cost an average of $3 per watt, installing solar roof tiles can cost between $3.80 to $9 per watt.
As far as longevity goes, solar panels and solar roof tiles are about the same. Both are manufactured to last about 20 to 30 years. Sunpower, one of the highest quality manufacturers of solar panels, offers a 25 year performance warranty, while Tesla has a 30 year performance warranty on their solar roofs.
Maintenance for solar tiles is a bit easier compared to solar panels. There are fewer nooks and notches for leaves and dirt to build up, and its harder for bugs and birds to make a home inside. Simply spraying solar roof tiles with a garden hose is enough to keep them clean, while solar panels usually require more specialised equipment. On the contrary, solar shingles are new, so we dont know how easy they are to service and repair when they start getting old.
Solar roof tiles also tend to be more durable than solar panels. Theyre not just for generating electricity, they are actually a roof material. That means they are built to be resistant to hard impacts, like hailstorms and debris from strong winds. Solar roof tiles are also made to be fire resistant, the same of which cant be said for solar panels.
Solar panels do have the benefit of being able to be removed after installation. If you were to sell your house after installing a PV system, you can decide to bring your solar panels, or leave them on the home as an added feature. Solar roofs cant be removed and molded onto another house. They are custom fitted for each installation. Although, homes with solar roofs can be sold for a $15,000 premium on average compared to similar homes without PV systems.

Solar roof shingles are a long term investment. Weighing the pros and cons is important, especially since youll be paying more than traditional solar panels. Doing research and knowing the ins and outs is a must before making a final decision.
Solar shingles and roof tiles have a low profile and blend in with the home. Oftentimes, its hard to tell that the home even has a PV system installed. This makes them more aesthetically appealing compared to traditional solar panels.
Solar roof tiles arent just meant for producing electricity, they are actually a bonafide roofing material. That means they are durable and made to last. Some manufacturers even claim that their solar shingles are stronger than non-solar shingles. They are manufactured to withstand hailstorms, strong wind, and debris from heavy storms. Theyre also fire resistant.
Solar shingles can last as long as traditional solar panels, usually having warranties between 20 and 30 years.
Solar shingles are easier to maintain compared to solar panels. They dont have as many places for dirt buildup, nor do they have many places for birds and bugs to hide. This means that a solar roof can easily be cleaned off with a garden hose. Compare this to solar panel maintenance, where the panels have to be physically removed and cleaned.
Though they are costly, solar roof tiles are more cost-effective when installed on a new home. The cost of installation is much lower because the roof doesnt need to be removed and the house can have the solar shingles built-in.
Solar shingles are expensive when compared to traditional solar panels. On average, solar panel installations cost about $3 per watt, while solar roof tile installations can cost between $3.80 to $9 per watt. The cost of removing the roof is a big part of the cost. Sometimes, installing a new non-solar roof and a conventional solar panel system can actually cost less than installing solar shingles.
Solar roof tiles take more time to install due to the roof removal. Whereas conventional solar panels may take a few days to install, solar shingles can take about two weeks.
Since solar roof tiles are still relatively new technology, styles are limited. Currently, most solar shingles tend to be black in color and completely flat. While some like the sleek appearance, its nice to have variety in styles. Tesla is now releasing different styles of their solar roof tiles, which look like more traditional roof tiles in both color and shape, while still generating electricity.
Most solar roof tile installations require complete removal and replacement of the roof. That adds to the cost of installation. For a home with expensive roof materials, this can be a major setback.
Solar shingles are custom built for the house they are installed on. That means they cant be installed on another home if you decide to get up and move, unlike traditional solar panels. Though, this can be considered a pro, seeing as homes with solar roofs can be sold for a premium.
Solar shingles tend to be less efficient than solar panels. Whereas the best solar panels have efficiencies in the low 20% range, solar tiles hover in the mid to high teens, topping out around 18%.
The market for solar shingles is growing. More people are adopting the solar roof as an alternative to traditional solar panels. The collaboration between Tesla and SolarCity helped catapult the popularity of solar roof tiles into the mainstream. The solar roof is a hit with newly built homes, where owners can avoid the extra cost of replacing an existing roof. Though cost is still a deterrent for many homeowners, the increase in demand is pushing manufacturers to innovate new technologies that make solar shingles less costly and more efficient.
While solar shingles are gaining in popularity, theres still no word on when solar shingles will become competitive against traditional solar panels. Once the technology behind solar shingles is perfected, maybe we will see a transition to the sleek and invisible solar roof tile, and away from clunky and cumbersome solar panel arrays.
Solar roof tiles are still taking off. Though theyre sleek and help homes blend in, theyre expensive compared to traditional solar panels. The initial cost and amount of labor can put off some homeowners, who might not want to replace their entire roof. Those who are building a new home can circumvent the high cost by having the solar roof built in with their new home. Despite the high cost, its important to remember that you get what you pay for. Solar roof tiles also function as a legitimate roofing material, they arent as delicate as traditional solar panels. They can hold up to fire, hail, and strong winds, and can even be walked on. Making the choice between solar roof tiles and solar panels can be tough. So make sure to dig deep and have a full understanding of your needs before making a final decision.
Solar shingles are PV cells that are integrated into the roof of your home. They generate electricity while simultaneously functioning as a roof material.
Solar shingles cost anywhere between $3.80 to $9.00 per watt. The cost of installation is a significant factor as the entire roof must be replaced when installing solar roof tiles.
That depends on your wants and needs. Solar shingles cost more, but they have a low profile and are more aesthetically pleasing. They are also very durable since they are an actual roofing material, unlike solar panels. Solar panels are much cheaper, and can be removed and taken with you in case you decide to move or sell your house.
Solar shingles remain one of the most innovative ways to help power your home. These shingles are specially designed to enable you to harness the suns power, instantly reducing the energy you use. Learning more about this product is essential to ensure its the right one for your family. Lets go over everything you need to know.
Traditional solar panels were designed to be mounted on your existing roofing material. These shingles are packed with solar cells to help you utilize solar energy while functioning as regular shingles. They help protect your home just like asphalt shingles do. Theyre also lightweight and durable, like other roofing materials.
Shingles offer more aesthetic appeal compared to other solar options, like large solar panels. They blend seamlessly with your home, instantly making it look better than large solar panels posted in the yard. This can enhance curb appeal, making it an excellent idea for homeowners who want their homes to be more stunning.
Shingles are made to be durable. The creators of these shingles kept in mind how tough other roofing materials are and incorporated that same level of sturdiness into these. Shingles can easily withstand rain and harsh weather conditions.
Large solar panels can help you reduce energy efficiency, but several conditions must be met to use them. Panels on the roof must have ample room and are often heavier than shingles. These panels may not be an option for homeowners who have a limited amount of space in their yards. Solar shingles bring the possibility of using solar power to every homeowner.
Solar products like shingles are connected to the home via batteries. The solar energy collected is stored in a battery and later used by appliances and other things that use electricity in the house. This can help you save hundreds of dollars on your energy bills yearly, in our professional experience. Most solar products eventually pay for themselves, thanks to the massive savings.
Professional installation is paramount to ensuring the shingles blend seamlessly with your roof. Our experienced team will work with you to ensure your shingles are in the optimal place to collect solar energy. According to Business Wire, the solar roofing industry is expected to reach a value of $965 million by , making it a growing trend.
