India added 2.5 GW of solar open access in the calendar year (CY) 2022, a year-over-year (YoY) increase of 92% from the 1.3 GW installed in CY 2021, according to the newly released 2022 Q4 & Annual Mercom India Solar Open Access Market Report. The year marked the highest-ever annual installations of solar open access, driven by developers’ need to avoid a 40% Basic Customs Duty on solar modules. The higher tax rates became effective from April 1 last year.
