In one of the more closely-watched solar energy policy decisions in recent memory, the Arizona Corporation Commission (ACC) has ruled after two days of hearings to keep its net metering program, but implement a fixed fee of $0.70 per kW for solar rooftop owners starting in 2014. The split-decision resolution (a 3-2 vote) essentially means a few dollars extra per month for residential homeowners: $7 for a 10-kW system, though typical rooftop systems are generally a little smaller. Residents who already have solar, or get a signed installation contract before the end of the year, are not subject to the new fixed charge.

"Despite having some of the best solar resources in the nation, Arizona now has one of the shakiest policies for encouraging its development." -- Rhone Resch, President and CEO, Solar Energy Industries Association
