UNSW study finds east-west PV systems degrade slower than trackers

A study by UNSW researchers indicates that east-west ground-mounted solar systems experience up to 40% lower rates of certain degradation mechanisms compared to single-axis trackers. The findings suggest that mounting configuration directly influences module reliability, with thermal effects being most pronounced in southern Australia.
