Report: The way we power our homes may be on the verge of a major change

residential solarIn recent years, the growth of the rooftop solar market has been astounding. According to the Solar Energy Industries Association, the growth rate for at-home solar has been above 50 percent for three years running (2012, 2013, and 2014).

But if a new study is to be believed, the changes have only begun.

The way we get power is “at a metaphorical fork in the road,” says the new report released today by the Rocky Mountain Institute, an influential energy policy think tank. The reason is not just rooftop solar but, beyond that, the growing feasibility of home electricity systems combining solar panels with batteries for storage of energy.

“Grid-connected self-consuming solar will become economic for nearly all customers imminently, with grid-connected solar plus-battery systems following soon after,” notes the study, which was co-authored by Homer Energy.
