UNSW study finds tracker-based PV systems experience higher UV degradation than fixed-tilt arrays
Why it matters: PV system designers must now account for increased UV degradation in tracker-based arrays, especially in harsh climates.
- UNSW research indicates that PV module degradation is highly dependent on system design and geographical location.
- Tracker-based PV systems are found to suffer more UV degradation than fixed-tilt arrays.
- Tropical and desert regions are identified as areas where PV modules face the most significant environmental stress.
A new UNSW study reveals that photovoltaic (PV) systems with trackers experience greater UV degradation compared to fixed-tilt arrays, with tropical and desert climates imposing the highest stress on modules. This degradation is influenced by a combination of UV exposure, temperature, humidity, and atmospheric conditions, underscoring the necessity for climate-specific PV system designs.
