Insolation on developable areas of the SW United States.

Solar power in Arizona has the potential for, according to then-Governor Janet Napolitano, making Arizona "the Persian Gulf of solar energy".[1] A Renewable Portfolio Standard requires 15% renewable energy by 2025, and 4.5% from distributed renewable energy sources.



The first commercial solar power plant in the state is the 1997 95 kilowatt (kW) single-axis tracking photovoltaic plant in Flagstaff, Arizona, operated by Arizona Public Service (APS). In 1999, the City of Scottsdale covered an 8,500 square feet (790 m2) parking lot with photovoltaic panels, to both provide shaded parking, and generate 93 kW of solar power. In 2001 APS and Embry-Riddle Aeronautical University constructed a 190 kW single-axis tracking photovoltaic power plant. In 2002, Love Field Airport, in Prescott, Arizona began construction of a 5 megawatt (MW) photovoltaic power plant. By July 2006, it had a peak capacity of 2.879 MW AC.[2][3]

The Solano Generating Station is a proposed 280 MW parabolic trough solar plant, and is expected to be operating by 2012.[13] When finished the plant will provide 5% of the power from Arizona Public Service, the state's largest utility.

Net metering

As of October 16, 2008, Arizona has one of the best net metering laws in the country. Excess generation is rolled over month to month, and any surplus is returned annually to the consumer at the avoided cost rate.[14]

Renewable Portfolio Standard

The Arizona Renewable Portfolio Standard calls for 15% renewable energy by 2025, and 4.5% (30% of that) from distributed generation from renewable sources. Renewable Energy Certificates (RECs), may be purchased to meet the requirement.[15]

Arizona Solar Business Directory

The Arizona Solar Business Directory [16] contains almost 100 solar installation companies that do business in Arizona. It provides the most comprehensive list on the internet and is maintained by the Arizona Solar Power Society, which is one of the largest solar associations in Arizona. The business directory allow consumers and commercial customers to contact a number of different companies to get the best deal and best performing products in the solar industry.

Arizona Solar Watchdog Program

The purpose of the Arizona Solar Watchdog Program[17] is to teach consumers how to check a solar installation contractor's license, credentials and work history. Every contractor in Arizona needs to be registered with the Arizona Registrar of Contractors[18] Each contractor is issued a Registrar of Contractors' license number, which can be looked up using the step-by-step process outlined under the Arizona Solar Watchdog Program.
