The solar tracker market experienced significant challenges during 2021, writes Jason Sheridan of IHS Markit, with major price increases and availability disruption across raw materials and delays to global freight operations. Despite these challenges, global solar tracker shipments grew to over 50 GW in 2021, representing 15% year-on-year growth. This was driven by strong demand in key markets such as the United States, Spain, mainland China, Brazil, and Chile. Solar tracker installations are expected to reach over 46 GW in 2022, an increase of 20% compared to 2021.
