$0.20 per watt DC
Electric District No. 3 of Pinal County (ED3) provides incentives for their residential and business customers to invest in photovoltaics (PV). Residential and commercial customers installing PV systems up to 10 kilowatts (kW) in capacity may be eligible for rebates of $0.20 per watt. Commercial customers can install PV systems up to 20 kW in capacity. In no case can the rebate be greater than 50% of the installed cost. Equipment requirements and other details are available through the link above.
For billing purposes, customer energy usage in kilowatt hours (kWh) will be netted with the customer generation kWh each month. If usage exceeds generation, the monthly net use will be billed according to the applicable retail residential or commercial rate. A kWh credit can be carried forward to apply to future months payable at time of disconnect at avoided cost of energy rate or ED3 can pay for the credit at the avoided cost for energy on a monthly basis.
