Arizona has the fifth-most installed solar PV capacity in the country at an impressive 4,820 MW. This should come as no surprise; the immense amount of sunshine in the state makes the economics of going solar here hard to beat.
The cost of an installed residential solar system in Arizona is about $2.67 per watt before incentives. After claiming the 26% federal solar tax credit, the price is only $1.98 per watt. This puts the average cost of a 6kW system at $16,020 before incentives and $11,880 after claiming incentives.
There is little variance in cost between Phoenix, Flagstaff, and Tucson, as most of the best solar companies have offices in each city.
If you pay federal income taxes, 26% of your solar system cost can be claimed as a deduction to your federal tax liability. Remember, when filling out the paperwork that the credit is for 26% of the system cost after claiming other incentives.
Unfortunately, the Arizona state tax credit expired on Jan 1, 2021.
Prior to that, you could claim 25% of the cost of your solar system to be claimed as a deduction from your state taxes of up to $1,000.
A significant reason for the growth of solar power in recent years is Arizona’s RPS law. RPS stands for Renewable Portfolio Standard and requires the state’s Investor Owned Utilities (IOU’s) to source 15% of their power from renewable sources by 2025. If they don’t do this they will receive large fines.
Arizona also receives more sunshine than any other state. Solar panels in Arizona produce about 70% more power than in states such as New York. An excellent solar output means that it takes less solar panels to reach the desired output.
Unfortunately in December 2016 net metering was repealed by the Arizona Corporation Commission (ACC) however, a replacement system was adopted that while less generous, still gives homeowners something close to retail rates for excess solar power they export to the grid.
This is known as a feed-in tariff rather than net metering.
As of 2021, APS, SRP and TEP value your exported solar generation at an average of about 12.12 cents per kWh generated.
While this isn’t as good as the 1-for-1 net metering available in many other states, high solar production rates in Arizona mean that you’ll still be able to significantly reduce your electric bill through your electricity exports.
