The top 10 solar rooftop installers together contributed 70% of the total rooftop solar capacity installed in 1H of 2020, with the remaining 30% installations spread among smaller installers in a fragmented market.

As per Mercom’s Solar Quarterly Market Report, in the 1H of 2020, only 279 MW of rooftop solar was installed compared to 555 MW installed in the 1H of 2019.


The rooftop solar segment was severely affected by the pandemic, with installations falling by 50% compared to 1H of 2019. The first half of 2020 saw the COVID-19 pandemic severely affect the Indian solar market, resulting in a slowdown in solar installation activity across the board.

About 96% of the rooftop installations in the second quarter came from C&I consumers. The C&I segment is expected to recover in the second half of the year, especially in sectors like transportation, IT, consumer goods, pharmaceuticals, and textiles. However, residential solar remains beyond reach for most consumers, especially with the current economic downturn. Even though subsidies exist, neither the consumer nor the installers want to deal with it.

Tata Power Solar had the largest solar rooftop portfolio in 1H of 2020 and was also the largest solar rooftop installer cumulatively as of June 2020. Fourth Partner and CleanMax followed at the second and third spots.
