Capacity addition in solar energy sector has slowed down on account of lack of clarity on several policy issues and arbitrary bid cancellations, casting shadow over developer\u2019s sentiment, a report said. In wake of delayed capacity additions, development of the solar energy sector has constrained, CRISIL Research said in a report. \u201cThere were frequent bid cancellations, lack of clarity on GST procedures, and cost pressure from the imposition of the safeguard duty on imported cells While, GST clarity was lacking for over a year with a final decision taken in December by the GST council, it ended with an increase in taxation compared to what was expected by the industry,\u201d the report noted.

The CRISIL Research continued to monitor the same and remain aware of a possibility of upsides to our call, once regulatory risk is mitigated to an extent. In addition, it stated that adequate land availability, timely implementation of grid infrastructure, and the ability of players to raise low-cost funds will also be crucial enablers going ahead. Nevertheless, the outlook still remains fairly positive for the sector as the government remains ambitious about achieving its fiscal 2022 target.
