The company intends to deploy the funds for expanding its technology platform to service customers in the grid parity markets.

Proprietary remote solar design and instant quoting technology and strategic business partnerships have helped the firm double its US sales in 2013.

Sungevity CEO Andrew Birch said the company’s coalition now includes the world’s largest investor-owned utility company.

"That lineup combined with our customer-centric technology platform and the capitalization from this investment round, positions Sungevity to be the leading global solar brand," added Birch.

E.ON technology and innovation or strategic co-investment vice president Susana Quintana-Plaza said, "E.ON is in the business of servicing energy customers across several countries, and as new, more customer-centric solutions around residential solar arise, we want to provide our customers with the best solutions available."
