Photovoltaic systems

Solar photovoltaic (PV) panels convert energy from the sun into electricity. Arizona is an ideal location to install solar systems because we receive a relatively high amount of annual sunshine.

What are the benefits of solar power?

  • Produces no emissions and is replenished naturally
  • By offsetting fossil-fueled-power, it avoids the release of 2 pounds of carbon dioxide (CO2) and 0.5 gallons of water for each kilowatt-hour (kWh) produced
  • Makes use of one of Arizona’s greatest natural resources – sunshine
  • May reduce monthly electric bills for participating customers

Are utility incentives available?

TEP does not offer financial incentives to customers who install solar electric PV systems at their home or business. Thanks to falling PV prices, such incentives are no longer necessary to encourage widespread adoption of solar power systems. This helps keep TEP’s rates down, since previous incentives were funded through customer-funded surcharges.

Homeowners who purchase a PV system may qualify for federal and state tax credits to 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

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 such as wind, 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, such as wind. This is especially true if your house has a south facing roof slope that is free of shade for the majority of the day.

How can I connect to TEP's grid?

The forms below must be completed, signed and submitted to TEP before your system can be connected to our local distribution system. Submit completed forms via email to or by mail to Tucson Electric Power, Renewable Energy Department (Mail Stop HQE502), 88 E. Broadway, Tucson, AZ 85701.

The following form must be signed by the main TEP account holder and submitted in PDF format. Please note TEP does not accept Electronic Signature (EX; Docusign).

How do I get started?

Review the “FAQs” and “Technical Requirements” tabs for more information. The “Installer Resources” section has information on how you can find a licensed solar installer and how your installer can submit the appropriate solar application to connect to TEP’s grid.


Technical Requirements

  • 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.
  • A system must include a dedicated performance meter (on grid-tied systems, supplied by TEP) 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.
  • 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 TEP during normal business hours.
  • PV Production meter sets and net meter exchanges will be delayed for any project that has not followed the Non-Incentive Residential PV Application Process.

Installer Resources

Get Started

  1. Contact a licensed solar installer for an estimate. Please refer to the AZROC website.
  2. Meet with your installer to complete all required TEP program documents. Installer is responsible for submitting the appropriate application for your system.
