A growing number of economists say that rapidly shrinking costs have turned distributed solar generation into a disruptive technology that’s set for runaway growth. In fact, they say, it could ultimately upend the power distribution market. 
 “We’re completely unprepared for the opportunity that’s going to present itself,” says John Farrell, an ec...
