Any house owner who’s involved about carbon footprints and power prices has thought-about solar energy — normally, within the form of photo voltaic panels. However now there’s another choice: a complete photo voltaic roof.
Photo voltaic roofs are composed of photo voltaic shingles, aka photo voltaic tiles, that may match over current shingles or be put in on their very own.

What are photo voltaic shingles?
Photo voltaic shingles or tiles are like common roof shingles. However as an alternative of being product of asphalt, clay or slate, they’re product of glass that comprise photovoltaic cells. Photovoltaic cells act as semiconductors and switch power collected from the daylight into electrons, which may then develop into electrical present to energy your property. Every shingle sometimes produces between 13 and 63 watts of power, relying on the model (one of many newest, by business chief Tesla, claims to have a max energy of 71 watts). Whereas they each convert daylight to power, photo voltaic shingles are fairly totally different from the photo voltaic panels (we’ll dig into the variations later).
The primary photo voltaic shingles have been developed by DOW Chemical Firm, rolling out in 2011. However the idea started to get severe traction in 2016, when Tesla bought producer Photo voltaic Metropolis and commenced providing what it deemed the Tesla Photo voltaic Roof. At present, there are a number of manufacturers of the photo voltaic roof tiles accessible by means of producers like CertainTeed, GAF Vitality, Luma, SunTegra and naturally Tesla. (Dow dropped out of the sport.)
The common dimension of a photo voltaic shingle or tile is about 12 inches extensive by 86 inches lengthy. It takes about 350 photo voltaic tiles for a standard-size roof. Tiles weigh about 13 kilos per sq. foot, so most roofs can deal with them with out extra reinforcement.
What do photo voltaic shingles value?
