You don’t have to wait for Tesla, solar shingles are already here

Following Tesla's big (yet vague) news in April about production
solar tiles, the non-solar media world was beside itself. “Ultimately!”
they said. “What a great idea! This may transform the solar market!”

Nevertheless the solar market realized better. Solar tiles aren't new.
Building-integrated photovoltaics (BIPV)—the generation type solar
tiles drop under—have been around since the beginning. Talented thoughts
created a product that might incorporate in to a building's framework
and generate electricity. More than integrated tiles, BIPV also
involves semi-transparent solar sections used as replacement glass windows
 or skylights—everywhere solar cells are used as developing construction
materials.

And though Tesla's solar roof does appear to appear and deploy
differently than traditional BIPV, many questions still remain. While we
 await responses on facts such as for instance cost, productivity and durability (CEO
Elon Musk claimed Tesla should begin quantity creation that coming summer),
 here's a refresher on two already successfully established solar
shingle manufacturers.

SunTegra

When solar shingle godfather Dow departed the marketplace using its Giant
program in July 2016, the wondered if this is the conclusion for BIPV.
 Incorrect, claimed SunTegra CEO Oliver Koehler. SunTegra, formerly
known as Integrated Solar Engineering, generates solar shingle and solar
tile roof methods with crystalline plastic engineering, while Dow used
expensive and less effective CIGS thin-film.

“We base our items on standard crystalline solar cell engineering,
which enables people to touch in to the industry's current economies of scale
and provide a aggressive charge and related efficiencies and stability
to standard solar sections,” Koehler claimed in a SPW interview.

SunTegra's Solar Shingle and Solar Tile roof methods replace roofing
resources and are most readily useful installed on a brand new roof or remodeling project.
The merchandise fix directly to the roof deck in a overlapping pattern.
 A patented TegraVent style promotes ventilation, lowering heat
through the program and increasing energy production.

SunTegra Shingle (2 x 4 ft) is ranked at 100 M, while SunTegra Tile (1.5 x
 4 ft) is 67 W. Both have ranked efficiencies close to 15%. SunTegra
methods have guarantees much like traditional racked solar methods: a
20- to 25-year power guarantee and a 10-year product guarantee.

The actual gain comes when comparing non-solar roofs and standard
rack-mounted solar methods with solar shingles. Asphalt shingle roofs
have a 15- to 30-year lifetime (depending on climate). Roofs often have
to be replaced before a racked solar program reaches its end of life.
Removing and reinstalling a racked program is really a pain. A BIPV program continues
 in place and usually exceeds a non-solar roof's lifetime, keeping the
headache of a solar reattachment and the expense of a re-roofing.

SunTegra got its come from 2013, and its leadership has ages of solar
experience. Their marketing attempts have taken off in recent months, and
the organization seems positioned to ascertain some solar shingle market
dominance.

CertainTeed

Along with a rack-mounted PV program, common construction material
company CertainTeed also generates its Apollo II and Apollo Tile II
BIPV systems—and has for years. With increased than 100 years'knowledge in
the roofing company, CertainTeed provides a distinctive level of understanding
 of solar roofing items and how they work as building-integrated
systems.

The Apollo II items create 60 M per shingle and are wind-resistant
and water-tight. Apollo II's all-black style and Apollo Tile II's
brown/black style permit the sections to visually blend in with certain
shingled and tiled rooftops. Also made from crystalline plastic,
CertainTeed's solar tiles have equivalent effectiveness to other solar
shingle items available on the market today.

Rafters aren't needed for successful installation. Apollo II solar
tiles fix directly to the roof sheathing with standard deck
screws. CertainTeed has created comprehensive installment
instructions because of its methods and teaches credentialed installers on
appropriate installment techniques.

In a current report unique to SPW, CertainTeed product progress
chief of photovoltaics Christopher Fisher discussed the common savings
 related to the Apollo II systems.

“Simplicity and effectiveness total up to considerable savings, which can be
transferred along to the homeowner,” he said. “For an average 6-kW Apollo II
program, the common savings on roofing resources and job alone when
compared to separate your lives roofing and roof-mounted PV installations is $770
to $1,210. For an average 6-kW Apollo Tile II program, savings is usually
between $1,260 and $2,520.”

CertainTeed is really a bankable organization; running a business because 1904, owners may be
 confident the 25-year power generation guarantee and 15-year installment
 craftsmanship guarantees is going to be honored.
