Today in Cleantech

Solar inverters, the unsexy electronic devices that help solar panels exchange energy with the power grid, have been heating up since last fall, and a new report from Greentech Media (sub reqd) takes a look at some of the new entrants to the space and market dynamics. (Solarbuzz has a complete list of companies.) The big shift, however, seems to be increasing sophistication among companies; today’s partnership announcement between Echelon and SMA Solar Technology is the latest indication of that trend.
