Dive Brief:

• Solar installations in Arizona Public Service's territory have plummeted since state regulators added a roughly $5/month fee for rooftop solar.
• In January, 280 rooftop projects were added, down from 583 a year ago.
• The solar market in Arizona was hurt by the fight over the solar fee, according to a solar developer.

Dive Insight:

The solar market in Arizona has taken a nose dive while it is picking up in other states. “It will be difficult for any solar company to stay in that market,” Bryan Miller, SunRun vice president for public policy and power markets, said.

However, we'll need to wait at least a few months to see if this is a temporary drop-off or a permanent change in attitudes towards solar in Arizona.
