$SolarEdge Technologies (SEDG.US)$ $Enphase Energy (ENPH.US)$ There are also companies that manufacture hardware and software to actually put renewable energy into the grid.

This is achieved through inverters, and SolarEdge and Enphase Energy are among the companies that manufacture these specialized inverters.

Due to general weakness in renewable energy stocks, the stocks of these two companies have both fallen by double digits this year. But research firm KeyBanc recently stated that Enphase is about to rebound.

"We are optimistic about the micro-inverter business. Enphase has a considerable market share in this business and is in a favorable position," the company said, while rating the stock as "overweight."
