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 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 UES' electric 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
