![]() ![]() Both are manufactured to last about 20 to 30 years. 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.Īs far as longevity goes, solar panels and solar roof tiles are about the same. In many cases, installing both solar panels and new non-solar roofing separately can cost less than an entire solar roof tile installation. Solar panels are cheaper to install, mainly because they don’t require a complete replacement of the roof. ![]() Solar shingles also lack many of the extras required with a solar array, as the mounting racks, brackets, and external wiring are absent. 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. They all tend to have the same look dark in color and completely flat. Granted, solar tiles are still limited in styles. They blend in better with the home, and passersby often can’t tell that the house even has an installed PV system. Solar shingles are more appealing to the eye. The major difference between solar shingles and solar panels are the aesthetics and the price. Some might see the switch as a worthy investment, considering they get a sleek new roof along with a reduced energy bill. They have a dark color and a shiny, sleek look. Many like solar roof tiles simply for the aesthetic value. 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 solar shingles require completely removing the old roof and having it replaced, which can put off many homeowners. ![]() Those who already have expensive roofing materials might see it as an extra cost. Some homes might not be suitable with solar roof tiles. Solar roof tiles can be installed alongside normal roof tiles. Some manufacturers claim that their solar roof tiles are stronger than traditional roof tiles. Solar roof tiles have proven to be quite durable, being able to withstand strong winds and hailstorms. It’s important to remember that you’re not just getting a PV system, but a roofing material as well. 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. 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. The price depends on the manufacturer, system size, and type of solar tile. Solar shingles tend to be quite expensive. On average, they can cost between $3.80 to $9.00 per watt. 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 doesn’t shine, as well as on the perimeters of the roof. Some are made with flexible semiconductor materials, while others are multi-layered and use traditional c-Si solar cells. Some can be applied directly onto existing roof tiles, while others replace the roof completely. This means they can achieve higher efficiencies and be more competitive with traditional solar panels. Whereas early solar tile manufacturers used flexible CIGS as a semiconductor, more companies today are utilizing crystalline silicon solar cells. The average size of a solar roof tile is 12 in x 86 in (300mm x 2180mm), and each solar roof tile can produce anywhere between 50 to 115 watts. The electricity is then used to power your home, either directly, or via a generator or system of battery storage. ![]() Sunlight strikes the solar tiles, and the semiconductor material converts light energy into electricity via a chemical process. Solar shingles work just like traditional solar panels, except the individual modules are much smaller. Source: Joy Yu How do Solar Shingles Work? Solar shingles offer all of the same protections as normal roof shingles, but they also generate electricity. 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 first became commercially available in 2005, and the market today has grown to encompass several companies and manufacturers.
