APS has asked the state’s utility regulator for permission to install 20MW of PV capacity across 3,000 residential rooftops in the state, at a cost of $57m-$70m.

The plan will come as a surprise to many in the solar industry. APS is widely viewed in a negative light by the PV sector, due to its successful push last year to levy a monthly grid-maintenance fee on PV system owners – a move seen as a dangerous precedent for states with net-metering policies in place.
