Honeywell Launches Third-Generation Film To Protect Solar Panels
PowerShield® 3W is more durable than competitive films, allowing solar panels to reliably supply power even in the
May 16, 2012
MORRIS TOWNSHIP, N.J., May 16, 2012 – Honeywell (NYSE: HON) announced today that it has introduced its
third-generation laminate film designed to protect solar power panels from harsh environments
while helping them maintain power output
over their 25-year lifespans.
The product, PowerShield® 3W, is a cost-effective backsheet for photovoltaic panels that helps protect the electrical circuits
in solar panel modules, preventing moisture from entering the module and keeping electrical charges within the module.
These features help the module retain maximum power output while maintaining electrical safety.
PowerShield 3W is a laminate that is bound by a proprietary adhesive specifically designed for photovoltaic applications.
The adhesive helps make the laminate the most durable backsheet available from Honeywell to date.
“We are committed to developing solutions that increase the performance and overall lifetime of solar panels. Honeywell’s latest
innovative backsheet, PowerShield 3W, provides solar panel manufacturers with cost-effective and reliable protection for their
modules,” said Jerry Buchanan, global business manager for Honeywell’s photovoltaic backing systems business. “This backsheet has
been proven to perform in some of the most rigorous conditions.”
PowerShield 3W is available now, and leading module manufacturers are already including it in module designs.
Independent photovoltaic-industry laboratory tests show that PowerShield 3W can withstand more than 3,000 hours of accelerating
aging exposure at 85°C (185°F) and 85 percent relative humidity without losing structural integrity.
The backsheet’s superior adhesive offers excellent resistance to discoloration due to aging, which helps solar modules retain their
appearance and reflectivity. Like all PowerShield backsheets, PowerShield 3W offers high resistance to environmental degradation from
sunlight, heat, cold and humidity; strong resistance to acids, bases, solvents, salts and other chemicals; and resistance to excessive
moisture infiltration within a module.
The technology behind PowerShield 3W is based on Honeywell’s more than 30 years of experience as the world’s leading manufacturer
of high-barrier films for food packaging, industrial and healthcare applications, including packaging that protects drugs sold by
the world’s leading pharmaceutical companies.
Honeywell has an active and global research and development program for photovoltaic backsheets, with laboratories in Morris Township,
New Jersey, and Shanghai, China.
The Honeywell PowerShield supply chain provides module makers with a single point of contact for every component of their backsheet,
helping ensure a reliable supply and quality.
Honeywell also offers printable dopants and chemicals for the manufacture of solar cells, the SOLARC™ anti-reflective coating for
solar panels, and solar panel installation sales and services.
