The 28 solar startup deals in the fourth quarter of 2016 represented a two-year high, driven by declining prices and national pledges to renewable power.
CB Insights identified at least four distinct buckets of deals. Among installers of solar panels, PosiGen in Louisiana raised $20 million.
Solar cell manufacturer Heliatek, based in Germany, raised a $47 million Series D round.
D.light, a producer of solar-powered products, raised $15 million in Series D financing in 2016 and an additional $5 million in January.
Among energy storage solutions, salt-water battery maker Aquion Energy raised $33 million in a Series F round.
Altogether, solar cell technology companies attracted the most investors.
