Weathered PV backsheets have 46% faster flame spread than unweathered counterparts

Researchers in Singapore have accelerated the weathering of PV backsheets and investigated their flame spread behavior at different intervals. After 6 weeks, they found that weathered PV backsheets show 46% faster flame spread than unwearthered ones. They have also highlighted that current safety standards fail to account for long-term degradation.A research group from Singapore's Nanyang Technological University has investigated the flame spread behavior on weathered PV backsheets and has found they have a significantly faster flame spread than unweathered counterparts. Testing two commercially ...
