A flurry of mergers and acquisitions activity and an influx of venture capital dollars to solar service providers have led to innovation concentrated on creating new, lean business models in a fragmented landscape, notes Lux Research.

“Downstream startups raised over $1 billion, with SolarCity, SunRun, Recurrent Energy, SunEdison, and Solar Power Partners leading the way,” said Matthew Feinstein, Lux Research analyst and lead author of the report. “Solyndra raised a billion all on its own, but these downstream startups will achieve what Solyndra could not — success.”

Lux Research assessed the leading players in the downstream market as it stands today, sorting out the high-potential innovators. Among its conclusions:

• SolarCity dominates among residential installers. In the crowded residential installer/developer market, SolarCity is a standout performer — but it cannot afford to be complacent as it expands in the northeast United States. Many companies are partnering with SunRun, adding muscle to SolarCity’s biggest competitor. The Alteris-Real Goods Solar merger in December has added a stronger player to the market.

• Commercial and utility-scale solar have few up-and-coming players. Tioga Energy and Enfinity lead the group of new large-scale developers. The acquisitions of Recurrent Energy, SunEdison, and Solar Power Partners led to concentration of large-scale development in the hands of larger companies or vertically-integrated suppliers First Solar and SunPower.

• New entrants keep popping up on the back of venture dollars. A burst of entrepreneurial activity, driven by venture capital, is ensuring a steady stream of high-potential startups. In 2011, six solar installers were among Inc. Magazine’s top 50 fastest growing companies in the U.S., including Greenspring Energy, re2g, SunDurance Energy, OnForce Solar, and FLS Energy.
