Amongst module suppliers, Canadian Solar led the charts with 12.9% market share followed by JA Solar (11.4%) and Trina Solar (7.9%). Adani, at the number 8 spot, is the only Indian module supplier. China’s new policy to scale back solar is likely to further eat into the domestic manufacturers’ share. ABB continues to dominate the inverter market with 20% market share. However, it is closely followed by Huawei (17%), which has climbed up from 10th place last year. Sungrow and TMEIC follow with market shares of 14% and 11% respectively.
