“2021 was the best year for solar corporate funding as well as mergers and acquisitions since 2010. Financing activity bounced back strongly following a COVID-19-affected 2020. There was more money than ever chasing deals and more demand than supply of attractive companies and assets as organizations and funds look to fulfill their ESG and clean energy mandates,” said Raj Prabhu, CEO of Mercom Capital Group.

Global VC in the solar sector in 2021 came to $4.5B, 281% higher compared to $1.2B in 2020. This is also the highest VC funding in the sector since 2010. There were 11 VC funding deals over $100 million (M) apiece in 2021.
