Solar shingle

Solar shingles , also called photovoltaic shingles , are solar panels designed to be used as a propulsion machine, such as asphalt shingle or slate, while also producing electricity. Solar shingles are a type of solar energy solution known as building-integrated photovoltaics (BIPV).

There are several varieties of solar shingles, including shingle-sized solid panels that take the place of a number of conventional shingles in a strip, semi-rigid designs containing several silicon solar cells that are sized more like conventional shingles, and newer systems using various thin-film solar cell technologies that match the standard of both dimensions and flexibility. There are also products using a solar panel with a maximum of 100 watts DC rating per shingle. [1]

Solar shingles are manufactured by several companies [2] but Dow and CertainTeed . [3] Other active companies in the US include SunTegra Solar Roof Systems, [4] and Atlantis Energy Systems (asphalt and slate systems), [5]

History

Commercial solar shingles were first available in 2005. In a 2009 interview with Reuters, a spokesperson for the Dow Chemical Company estimated that their market entry into the market would generate $ 5 billion in revenue by 2015 and $ 10 billion by 2020. [2] Dow solar shingles [6] first became available in Colorado , in October 2011, but the company stopped selling them only five years later in mid-2016. [7] As recently as October 2016, Tesla has entered the solar shingle space in a joint venture with SolarCity . [8] Now as of June 28th, 2016, the Solar Shingle will be held in the Solar Shingle business, which will be held in conjunction with solarcars for Solar Shingles in the US.

Description

Solar shingles are photovoltaic modules, capturing sunlight and transforming it into electricity. Most solar shingles are 12 in x 86 in (300 mm × 2.180 mm) and can be directly applied to the roofing cloth. When applied they have a 5 in × 86 in (130 mm × 2.180 mm) strip of exposed surface. Different models of shingles Some can be applied directly to roofing felt intermixed with regular asphalt shingles while others may need special installation.

Some manufacturers, such as Dow Chemical Company, use solar thin-film technologies, such as CIGS to produce electricity, which are less common in the solar industry than silicon-based cells. Other manufacturers, such as CertainTeed and SunTegra, have chosen to use the industry-standard monocrystalline gold polycrystalline silicon solar cells in their Apollo II and SunTegra Shingle, respectively. The installation methods for some solar shingle solutions can be facilitated by the fact that they are more often used by solar panels.

Solar shingled roofs tend to have a deep, dark, purplish-blue or black color, and therefore look similar to other roofs in most situations. Tesla Solar has developed in many styles to better match traditional roofs. [9] Homeowners may prefer solar shingles because they avoid having large panels on their roofs. [10] Coming in 2018 Tesla will offer shingles in slate and Tuscan styles, these are the first of the solar shingles which will look like a slate. [11]They have been hail rating, filmed at 2,500 frames per second, each 2 “hailstone is track 100 mph on impact.” Which shows how these new options are also safer in disasters . [11]

Cost

The cost of solar shingles can range from $ 4.00 per watt up to $ 12.00 per watt installed depending on the manufacturer, technology used, and system size. As of Q3 of 2015, the average cost of a traditional, roof-mounted residential solar panel installation in the United States was just above $ 3.50 per watt, according to the Solar Energy Industry Association . [12] While solar shingles are typically more expensive than traditional solar panels, some companies in recent years have made strides in the gap between solar panels and solar panels.

According to Dow Chemical Company reports, a typical residential install of 350 solar shingles can cost at least $ 20,000; however, federal and state incentives may be expensive depending on the cost. [13]

Solar contractors typically offer homeowners a full-service price for solar installation, which includes the equipment purchasing, permit preparation and filing, registration with the local utility company, workmanship warranties, and complete on-site installation. Because photovoltaic solutions produce power in the form of direct current (DC) and the standard in homes is alternating current (AC) , all grid-connected solar systems include an inverter to convert DC to AC.

Availability

As of 2015, companies currently offering solar shingles in the United States include Dow, [14] CertainTeed, [15] Forward Labs, [16] SunTegra Solar Roof Systems, [4] and Atlantis Energy Systems (asphalt and slate systems). [5] Sun Energy Engineering, [17] and OkSolar.com. [18] Tesla Solar entered the solar roof market in 2016.

In 2015, SunTegra Solar Roof Systems [4] completed icts first facility in Canada with a homebuilder on the first net zero home in London, Ontario.

Former companies include Uni-Solar, which filed for bankruptcy in 2012, and “Pfleiderer-Dachziegelwerke”. [19]

Dow announced on June 28, 2016, that it will cease manufacturing powerhouse modules. [20]
