The rooftop solar projects have not experienced a high growth rate as compared to ground-mounted solar projects. Total rooftop solar installations as of December 2019 is 5.440 GW vis-à-vis a cumulative installed solar capacity of 35.7 GW. Rooftop solar has been maintained at ~10% share of overall solar capacity. This is much lower than other key markets such as the US, Germany, China, Spain, and Australia.
According to a report, India needs to prioritize solar rooftop among residential and industrial users for achieving its 100GW solar energy target by 2022. Demand aggregation rooftop solar mechanism could help expedite energy efficiency and scale up the deployment of solar power in residential complexes and MSMEs, according to WRI India.
