System lifetime is key to investment returns. In fact, investment returns for solar can increase by more than 30% if the lifetime of the solar system can be increased from 10 to 25 years. PV backsheets play a critical role, providing long-life protection to the solar panel, which safeguards the system and enables long-term returns.
DuPont™ Tedlar® PVF film-based backsheets have been tested in the field for more than 30 years in all kinds of climates (desert, tropics, temperate, marine, mountain). Long-term outdoor exposure is the ultimate test for all module components, ensuring material quality and manufacturing consistency.
In the absence of long-term, field-proven performance, many of today’s newer backsheet materials rely on various lab tests to suggest performance in the field. Unproven or inferior materials may save a few cents per watt, but focused field studies are proving these materials can degrade in as little as 5 years, putting system performance, payback and safety at risk.
Tedlar® PVF film-based backsheets continue to be the leader in
backsheet durability over time – delivering proven backsheet
performance and lasting value, day after day.
