Solar energy

With sunshine so abundant in Arizona, it makes sense to harness its energy. SRP supports this clean source of power by participating in the projects listed below and offering you tools to determine whether solar power is right for your home.

Solar energy for your home

You can harness the sun's energy to create electricity at your home by installing a solar electric or solar hot water heater. Please see:

  • SRP EarthWise Solar Energy: SRP customers who install a solar electric system or solar water heater at their home may qualify for a cash rebate to defray the cost of going solar.

Solar power plants at SRP

The sun is a free and inexhaustible source of fuel capable of producing emission-free electricity. By capturing this energy in a photovoltaic (PV) system, which comprises modules of semiconductor cells, solar photons are converted into energy.

As part of its EarthWise Energy™ program, SRP operates a 200-kilowatt (kW) photovoltaic (PV) system at the Agua Fria Generating Station in the western Phoenix, as well as two 100kW PV systems installed at the Rogers substation in Mesa.

SRP's PV systems use modules of semiconductor cells to capture solar photons and convert them into electricity. The modules are arranged into larger arrays that can be tilted in response to the sun's angle, allowing us to maximize the amount of power produced by each system, regardless of the time of day or particular season.

Community projects

Construction and parking: SRP has partnered with Calex Homes to promote and develop solar generation in the Phoenix area and is working with other builders on solar water heating and home photovoltaic systems.

In another partnership, SRP joined with the city of Phoenix Transit Department to install solar power panels on covered parking structures at an Ahwatukee Foothills Park-and-Ride facility. The panels produce enough energy to provide power to 100 homes annually. SRP also installed a solar energy system at the Red Mountain Library parking lot in Mesa.

Zoo signs: Photo of a solar zoo exhibit sign.As part of an ongoing commitment to promote renewable energy, SRP donated 17 solar-powered exhibit signs to the Phoenix Zoo in 2004.

Located throughout the Tropics and Africa Trails, the signs feature information about the animals as well as personalized recorded messages from the zookeepers.

The signs are part of the SRP EarthWise Energy program, which funds solar and other sources of renewable energy while educating the public about the benefits and need for solar energy.

Educational projects: SRP installed small solar systems at South Mountain Community College, Cesar Chavez High School and Scottsdale Community College.

Several educational solar energy experiments also are featured on this site.

The future of solar energy

Unfortunately, the current costs of installing photovoltaic equipment makes this form of renewable energy an expensive option for power generation. As a stronger market for this energy develops, we hope to see costs decline.

In the meantime, SRP continues to assess other solar technologies to find the most cost effective and environmentally beneficial source of clean energy.

SRP is also part of a consortium of energy companies requesting proposals to build a solar thermal power plant. The proposed plant would generate 250 MW of electricity.
