Next review Nov 2026
By the end of 2023, the globe had reached 1,748.9 GW of cumulative solar PV capacity, with solar helping drive 72% of all renewable power additions that year. What stands out for HR in the solar industry is how quickly the workforce pressure builds across very different segments, from rooftop systems in the US to utility scale plants worldwide. The mix of fast growing demand, shifting capacity shares, and technology performance targets is why hiring and training plans have to keep pace with the data.
