The Leader in Backsheet Durability Over Time
Less than 0.05% of Tedlar-based backsheets showed defects in global field inspections:
Since 2011, DuPont has conducted inspections of fielded solar modules in different geographies and climates in North America, Europe, Asia Pacific, and the Middle East. To date, DuPont has surveyed over 4.2 million panels from 275 solar fields and 79 module manufacturers, accounting for over 1.04 GW.
PVDF and Polyamide backsheet defects increased by 51% and 18% since last year.
And compared to Tedlar® backsheets, defect rates for PVDF and PET backsheets were 200 and 70 times higher.

China leads the world in its rapidly growing population, economy, and energy consumption and production, and the Chinese government has aimed to achieve 15% total energy consumption from non-fossil fuels by 2020.
We’ve provided superior backsheet materials on a massive scale and collaborate on field research for performance analysis and optimization to help them achieve their expansion goals.
Frequent sandstorms and strong UV rays are the types of severe conditions that solar panels in Western China are expected to withstand for 20 to 30 years.
In competitive backsheets, this caused quality issues, including significant or complete power loss and faster degradation after less than 5 years
Given these extreme climates, it’s even more critical that PV systems use materials proven to perform in similar environments.
If you see degradation of panels: Log onto our Solar Panel Self-Diagnostic Tool and our experts will guide you through steps to identifying and correcting problems.
What happens when you mix environmental factors with a backsheet ?
To understand how backsheets are performing around the world, we surveyed and tested competitively installed backsheets. In those backsheets that didn’t use Tedlar®, we found many early signs of visual defects and degradation, including in installations only 3 to 5 years old.
DuPont™ Tedlar® has the lowest failure rate in the industry despite being in the field longer than any of our competitors. In some cases, over 35 years.
DuPont™ Tedlar® is proven to experience 50% less power loss over competitor backsheets, and have been in the field over 35 years with no observable changes.
Clear Tedlar® film for backsheets: A game changer for bifacial panels
Compared to dual glass bifacial, panels made with Clear Tedlar® backsheet are lighterweight, easier to install, transport, maintain and clean, helping to lower both the LCOE and total ownership costs.
DuPont™ Tedlar® is a highly versatile, polyvinyl fluoride film that provides a long-lasting finish to a wide variety of surfaces exposed to harsh environments while its inert, non-stick properties make it an excellent release film for parts processed under high temperature and pressure.
