February 22, 2013 - Today, Rocky Mountain Institute (RMI) announced the launch of the Simple BoS (Balance of Systems) project, a partnership with Georgia Tech Research Institute (GTRI), to explore the cost divide between the U.S. and Germany for residential solar photovoltaic systems. Balance of System (BoS), or “soft” costs now account for more than 60 percent of the price of U.S. rooftop PV systems, yet such costs are 75 percent lower in Germany, the worldwide solar market leader.
In most areas of the U.S., solar PV remains an expensive energy option, even as module costs have decreased significantly. RMI sees reducing BoS costs—all the related solar energy system costs besides the panels themselves including permitting, financing, installation, and inspection—as a critical pathway to affordable PV and widespread solar adoption. read more>>>
