Honeywell Launches Third-Generation Film To Protect Solar Panels
- Published: Friday, 18 May 2012 09:16
Honeywell has announced 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.
