Strong growth in solar panels with defects in 2020
In the past year, SolarTester operators have tested and assessed more than 20,000 panels. It was discovered that more than 42% of the new modules tested had at least one defect, ranging from non-critical to highly critical. This represents an increase of 61% compared to 2019. Damage checks on existing projects also show more than twice as many tests done compared to 2019. In the damage checks that were completed, 70% were assessed as Class A. Approximately 30% of these tested modules contain critical to highly critical defects and have therefore been rated as class B, C or D. This indicates that it can be worthwhile to perform a damage check instead of replacing all the modules immediately.
