Honeywell unveils laminate film to protect solar panels from harsh environments

Greentech Lead America: Honeywell has unveiled its
laminate film to protect solar power panels from harsh environments.

The backsheet for
photovoltaic panels will be helping them maintain power output over their
25-year lifespan.

PowerShield 3W
is designed to help protect 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.

“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.

Honeywell said
PowerShield 3W is available now, and module manufacturers are already including
it in module designs.

The backsheet’s
adhesive offers resistance to discoloration due to aging, which helps solar
modules retain their appearance and reflectivity. PowerShield 3W offers
resistance to environmental degradation from sunlight, heat, cold and humidity.

According to
photovoltaic-industry laboratory tests, 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.

Honeywell said it
has 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

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.
