LONGi Unveils Its First BIPV Product: LONGi Roof

PVTIME - On Augst 7, Chinese wafer and module manufacturer LONGi introduced its first BIPV product, LONGi Roof, at its product release ceremony held at the InterContinental Hotel in Shanghai just ahead of the opening of SNEC’s exhibition.

LONGi General Manager, Chen Pengfei, annoucing the release of LONGi Roof.

As LONGi’s first building integrated photovoltaics product, LONGi Roof inherits the company’s stable, reliable, and cutting-edge technical genes, and perfectly combines reliable building materials and high efficiency photovoltaic power generation. LONGi Roof is designed for commercial and industrial rooftops and will aim to redefine the public perception and acceptance of BIPV.

Prior to product development, in
order to pinpoint the concerning aspects of currently available BIPV products, LONGi’s
product design and R&D departments met and engaged in meaningful dialogue with
many commercial and industrial rooftop owners. Through targeted development, LONGi
Roof was designed to meet and exceed the consumers’ needs for a BIPV product that
must be safe, sturdy, and offers efficient and reliable generation.

In terms of product performance,
LONGi Roof has reached top level safety and reliability standards and offers 9
major advantages:

Improved waterproofing: 360-degree independent
seaming, butyl filling sealing, full-length vertical non-overlapping, and
dynamic sealing of its sliding system.

Better fire protection: automatic
shutoff equipment, 2mm tempered glass on the surface, noncombustible aluminum
zinc plated steel plates at the bottom, and is certified Class A noncombustible

Stronger wind resistance: can withstand maximum wind
pressure of 0.85KN/㎡, support every 30cm span, and can pass a 2400 Pa wind
load test.

Improved heat dissipation: special heat dissipation
channels, operating temperature 10 ℃ lower than that of competing
products, which can increase power generation by 4% and reduce the energy
consumption of indoor air conditioning.

30-year service life: 30-year linear power output warranty,
10-year product warranty.

Integrated BIM: exclusive BIM system where all modules can
be traced to the source, realizing refined management.

Larger installed capacity: LONGi Roof’s treadable design can
increase installed capacity by about 10%.

Antifouling design: double sided frameless components reduce
power loss and module power attenuation caused by ash deposition.

LONGi Roofs are not only suitable for newly built commercial
and industrial roofs, but can also benefit older rooftops that will be needing
renovations. With more than 4 billion square meters of new construction
completions each year in china, an installed capacity of 20GW can be achieved
with only 5% adopting LONGi Roofs.

LONGi President, Li Zhenguo, addressing the attendees at the release ceremony.

Li Zhenguo President of LONGi, said at the product release
conference that PV power generation is the most effective way to solve the
current global climate and other energy related problems. The continuous establishment
of the whole society’s awareness of PV power generation, distributed PV power
generation, especially within the commercial and industrial market, will usher
in broader development opportunities. Therefore, LONGi’s launch of its BIPV
product line is a strategic move which broadens its industrial reach, improves
its product chain, and encourages industrial upgrading, which is of great significance
to not only LONGi but the industry as a whole.
