Off Grid Electric closed its Series D funding Friday with $55 million from Helios Investment Partners and General Electric’s venture capital arm. The round adds to a growing roster of home solar providers operating in developing countries that are pulling in large sums. In 2017, M-KOPA raised $80 million, Greenlight Planet raised $60 million and Developing World Markets financed 11 companies with a $60.8 million social impact note. According to GTM Research solar analyst Benjamin Attia, Off Grid's $55 million is likely the biggest pure venture equity investment for a home solar provider on record.
