PV backsheets

Your first line of defense for module protection

New Endurance backsheet D15

All-purpose excellence

It’s about time for the DSM Endurance backsheet

How much is solar panel backsheet failure costing your business? As the final layer on the back of a PV module, the backsheet is literally your first line of defense against the elements. Which is why we created the Endurance backsheet.

Featuring the strongest core layer in the industry, it’s the most durable PV backsheet on the market today - delivering long-term protection against moisture, mechanical stress, sand abrasion and UV. With 15 million modules installed since 2015 and zero failures…it’s built to last.

Why backsheets matter

Of all solar modules installed in 2020, an astonishing 1% will need to be replaced because of faulty backsheets, with a potential repair bill of $500 million.
