A proven backsheet

15 million modules: 0 failures

The ultimate in module protection

Today, DSM has more than 4GW of backsheets installed in solar parks globally, totaling 15 million modules – with zero failures. It’s a proven backsheet solution.

Superior backsheet performance

Five years of performance data from 9 sites dating back to 2015 reveals not a single backsheet failure: no yellowing, no cracking, no excessive abrasion, no chalking, and no delamination. In fact, we’ve seen evidence at sites that modules featuring the DSM backsheet actually perform better that their counterparts in terms of energy yield and/or degradation rates.

It’s why one of the world’s leading module manufacturers, Silfab, has now extended the warranty offered on their modules featuring DSM Endurance backsheet to 30 years. In short, the Endurance backsheet is built to last.

The analyst’s view

The numbers don’t lie, and neither do the analysts.

Black & Veatch: an independent assessment of our backsheet in 2018 found many aspects to be superior and/or ranking among the top of the list compared to other commercially available backsheets.

Enertis (Technical Advisor): “Co-extruded polyolefin core backsheets have a lower probability of field failure than PET core backsheets. Consequently, a PV project using such backsheets will exhibit a longer useful life.”

Winner AQM Award

Our Endurance backsheet was recognized at the TÜV Rheinland’s All Quality Matters Solar Congress in 2019, winning the ‘PV Component Backsheet’ category. The product was extensively tested and  assessed on everything from breakdown voltage, reflection and tensile strength to elongation retention, yellowing index and volume resistance.  

Certified for TÜV-SÜD’s accelerated aging test

Our Endurance backsheets were the first to pass the integrated stress sequence accelerated aging test carried out by TÜV-SÜD. This incredibly tough material evaluation simulates natural conditions through a combination of damp heat aging, ultraviolet aging, high-and-low temperature cycle aging, and other sequences.
