RECPP
Renewable Energy Credit Purchase Program

Solar-powered electric systems.

Solar systems are best suited in areas that receive a relatively high amount of annual sunshine like Arizona. The productivity of photovoltaic systems depends upon installation methods and location. In particular, solar systems are impacted by shading, photovoltaic panel horizontal tilt angle and azimuth. These factors impact how solar capacity is reported by UES which determines the amount of incentives received by customers.

Is solar generation right for me?

The decision to install a photovoltaic system on your property should be made after you consider a variety of factors. Local building codes, availability of sunlight, maintenance requirements and the cost of other alternative energy options should all enter into your decision to install solar generation.

In most populated areas of Arizona, a solar generator is more cost effective than other forms of renewable generation. This is especially true if your business has a south facing roof slope that is free of shade for the majority of the day.

Solar power benefits.

  • Produces no emissions and is replenished naturally.
  • Reduces greenhouse gases.
  • Saves the release of 2 lbs. of carbon dioxide (CO2) for each kilowatt-hour (kWh) produced.
  • Saves the use of one-half gallon of water for each kWh of solar energy produced.
  • Saves the release of other emissions that result from the burning of fossil fuels such as nitrogen oxides, sulfur dioxide or mercury.
  • Makes use of one of Arizona's greatest natural resources - sunshine.
  • Provides customers with options to reduce their electric bills.

What incentives are available to UES customers?

UES offers 20-year up-front incentives (UFIs) for PV systems (see Table 1).

Table 1. Maximum incentives for PV systems.

UFI1 — 20-Year REC Agreement
Small commercial grid-tied $.10 per Watt DC
  1. An up-front incentive (UFI) provides customers a one-time payment based on their system size. In turn the customer signs a credit purchase agreement assigning UES the renewable energy credits for 20 years.
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.

Incentive eligibility.

  • You must be a UES customer.
  • The photovoltaic system must be installed at a UES service address.
  • You must purchase and install a qualifying photovoltaic system for this incentive.

All Systems

  • All systems shall be installed with a horizontal tilt angle between 10 degrees and 60 degrees, and an azimuth angle of +/- 100 degrees of due south. Installation configurations for some systems receiving a UFI will not be eligible for the full RECPP incentive.
  • A system must include a dedicated performance meter to allow for monitoring of the amount of electricity produced.
  • Photovoltaic modules must be covered by a manufacturer's warranty of at least 20 years.
  • Inverters must be covered by a manufacturer's warranty of at least ten years to receive a UFI and at least five years to receive a PBI.

Grid-Tied Systems

  • All photovoltaic modules must be certified by a nationally recognized testing laboratory as meeting the requirements of UL Standard 1703.
  • All other electrical components must be UL listed.
  • The inverter must be certified as meeting the requirements of IEEE-1547 — Recommended Practice for Utility Interface of Photovoltaic Systems — and it must be UL 1741 certified.
  • The utility meter, inverter, and utility disconnect will be installed in a location readily accessible by UES during normal business hours.

Next Steps

  1. Contact a licensed solar installer for an estimate. Please refer to the AZROC website.
  2. Fill out and submit the appropriate application for your system.
  3. UES will review your application to ensure it conforms to program requirements.
  4. UES will respond with a reservation confirmation within 30 days upon receipt of request.
  5. The installer will need to provide copies of city or county inspection permits within 60 days of reservation confirmation date.
  6. The installer will need to notify UES that installation is complete.
  7. UES will perform an acceptance test to verify system performance.
  8. You will receive payment within 30 days of acceptance test.
  9. UES is assigned exclusive rights to all RECs associated with project for 20 years.
