According Bloomberg report, citing data from GTM Research (GTM), Solar City is about to be overtaken by competitor, Sunrun, as the most active finance source to support the residential solar market by late 2017.

Bloomberg noted it’s been a tumultuous year for the residential solar industry, i.e., three of the largest installers, including NRG Home Solar, Sungevity and Direct Energy Solar, have gone bankrupt or exited the residential space, according to GTM.

Bloomberg said, citing insights from GTM, since SolarCity was acquired by Tesla, it’s become more oriented toward cash sales while Sunrun continues to promote residential business sales using lease financing as a selling tool.
