Arizona has the third most installed solar PV in the country behind only California and North Carolina at an impressive 3,463MW.
How much does a solar system cost in Arizona?
The cost of an installed residential solar system in Arizona is about $3.15 per watt before incentives. There is little variance in cost between Phoenix, Flagstaff and Tucson as most of the best solar companies have offices in each city.
After claiming the 30% federal solar tax credit and Arizona’s state tax credit, the price is only $2.00 per watt. This puts the average cost of a 5kW system at $15,750 before incentives and $10,325 after claiming incentives.
How does the 30% federal solar tax credit work?
If you pay federal income taxes, 30% of your solar systems cost can be claimed as a deduction to your federal tax liability. Remember, when filling out the paperwork that the credit is for 30% of the system cost after claiming other incentives.
How much will Arizona’s state tax credit save me?
If you have a state tax liability 25% of the cost of your solar system can be claimed as a deduction to your state taxes up to $1,000. Since it is very unlikely your solar system will cost less than $4,000 you can expect a $1,000 tax credit.
Why is Arizona such a strong market leader?
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 states 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.
Does Arizona have a net metering law?
When your solar system produces more energy than needed in your home the excess power is sold to your utility through the grid. Net metering requires your utility to value each kWh of power sent to them at the retail rate you pay for power. Net metering means that for each kWh of energy sent to the grid the cost of 1 kWh is offset from your bill.
When your solar system isn’t producing enough energy to power your home such as at night, energy will be drawn from the grid as normal. Net metering is important because most homeowners are away during the day and using little power in the home, this means more energy from your solar system can be sent to the grid and credited.
Unfortunately in December 2016 net metering was repealed by the Arizona Corporation Commission (ACC) however, a replacement system was adopted that whilst 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.
How much is the excess energy from my solar system worth?
From September 1, 2017 through August 31, 2018 APS value exported solar generation at $0.1290/kWh. APS’ rates for after August 31st are still undecided, however, will likely be less than the current incentive.
APS customers will receive the same value for energy their solar system sends to the grid for 10 years after interconnection is complete.
Salt River Project still offer net metering but only on a time-of-use plan. Time-of-use net metering means energy sent to the grid is credited at on or off-peak value depending on the time of day it was exported. SRP’s net metering program also includes a minimum service charge of $32.44 and includes a peak-demand charge.
What is a peak-demand charge?
A peak-demand charge is a per kiloWatt charge based on the highest amount of energy drawn from the grid at any one time. An average 2,500sq ft home in Arizona has a peak-demand of 4.26kW.
SRP peak-demand charges:
|Period||First 3kW||Next 7kW||Each additional 1kW|
