Residential solar is growing like crazy in the U.S. with help from companies including SolarCity (NASDAQ:SCTY) and SunPower (NASDAQ:SPWR), which offer $0 down leases and increasingly competitive sale prices. But utilities aren't happy about the growth; Pinnacle West's (NYSE:PNW) Arizona Public Services, Hawaiian Electric (NYSE:HE), and Duke Energy (NYSE:DUK) are three big names fighting hard against this energy source. 

The problem for utilities is that they don't own the solar asset and therefore can't generate a return in regulated markets. Plus, net metering rules mean they're essentially paying retail rates for the energy produced. 

Mike Klesta sat down with solar analyst Travis Hoium to see what the impact will be on residential solar, both short and for the long term.
