Solar PV systems are best suited for areas that receive high amounts of sunshine like Arizona. Solar PV systems have specific installation and location requirements. They are impacted by shading, horizontal tilt angle, and azimuth. These factors impact the amount of solar energy reported by UES and the incentive amount received by the customer.
UES offers 20-year up-front incentives (UFIs) for PV systems (see Table 1).
|UFI1 — 20-Year REC Agreement|
|Grid-tied||$0.10 per DC watt|
Note: To qualify for the UFI your PV system must have at least a 20-year manufacturer's warranty.
Projects receiving a UFI can receive no more than 50% of the system cost in the total incentive payout. Also, UES incentives in combination with all federal and state credits can be no more than 85% of total project costs. A customer must cover at least 15% of total project costs.
Customers may qualify for federal and state tax credits to further reduce the cost of the system. Talk with a tax professional about current tax credits available to you for a renewable energy system. You can also view federal and state tax credits at dsireusa.org.

View a list of PV installers operating in UES service territories. We recommend that customers meet with at least two installers. Evaluate each contractor's experience and consider other factors. Do they have any unresolved complaints, judgments or liens? Will they provide a list of references?
The installer or contractor installing your system must have a license from the Arizona Registrar of Contractors that authorizes them to install the kind of photovoltaic system that you purchase. This is necessary to receive an incentive under the Renewable Energy Credit Purchase Program (RECPP).
UES also requires the installer to possess an Arizona business license that is active and in good standing.
We recommend contacting more that one solar contractor for an estimate or evaluation of your energy needs. Many factors must be considered in sizing a system to meet your needs. If you are a current customer of UniSource Energy Services (UES), with a full year of consumption history, we can give you an approximate idea of what size system you would need. We recommend sizing a system to around 80 percent of your annual usage, not to exceed 100 percent of your annual average consumption amount.
Completed customer applications and the Renewable Energy Credit Purchase Agreements are reviewed by UES. Customers who are accepted into the program will receive an acceptance letter in the mail. Once the customer receives the acceptance letter, the installation can begin.
A City or County building permit is required for all residential systems and a copy of permit must be on file with UES within 60 days of application acceptance or application will be cancelled. Your installer will arrange for the installed system to be inspected by City or County officials. Once proof of that inspection has been submitted, UES will conduct a final system acceptance inspection. Once a system passes the final inspection, UES will process the customer's incentive payment.
You have 180 days to have the system installed. Please contact us if you are not able to install the system within 180 days.
Yes, just complete the Assignment of Payment section on the Residential Solar PV application.
A residential state tax credit of up to $1,000 is available, based on 25 percent of the cost of solar equipment and installation.
A federal tax credit of 30 percent of the cost of solar equipment and installation is available, with no cap on the tax credit.
* Please consult with a tax expert regarding eligibility requirements for State and Federal tax credits.
Expected system output: For every 1 kW (1000 watts of DC power generated) an estimated 130 to 150 kWh will be produced monthly (approximately $15.00 monthly). This figure is a rough estimate and is dependent on a variety of factors such as weather conditions and time of the year.
The UES Inspector is checking to ensure that all System Qualifications are met and that all applicable local codes are in compliance.
By reading the meter daily and deducting the current read from the previous day's read. Most inverters have a digital readout display. We recommend monitoring your system periodically.
Provided your inverter is large enough to safely handle the increased wattage of additional modules, and the increased DC wattage is at or above 1200 watts, a new application is required.
No, when the grid goes down, your inverter is programmed to shut the system down. This insures your system will not feed back into the electric grid system and cause injury to any UES employees working on power lines.
We realize that in today's solar market, what is ordered is sometimes not available. We will work with you or your contractor and accept like substitutes providing they meet all of the requirements of our system specifications.
