Arizona homeowners have access to an abundant state energy resource when they install solar heating systems.

With many parts of the state experiencing more than 300 days of sun each year, Arizona is an excellent place for homeowners to take advantage of solar energy. Arizona solar heating costs are remarkably low, by comparison, and they create many new ideas for homeowners looking to save.


One of the most popular applications for Arizona homeowners looking to take advantage of solar energy is in solar heating systems for your Arizona home the use of solar water heating systems. There are two basic types of solar water heating systems:

Arizona-solar-heating-2Active heaters/systems with active systems , a direct heater pumps water for household use through solar collectors, where the water is heated and then pumped into the home.

Passive/indirect systems with passive or indirect systems , heaters circulate heat-transfer fluid through the solar collectors and then into coils inside a water storage tank. There, the heat from the fluid is transferred to the household water supply for use

Tax credits/incentives:

The state of Arizona offers tax incentives for homeowners looking to add solar heating or solar energy systems to their homes.The solar energy credit is equal to 25 percent of the cost of the device. The maximum credit in a arizona offers tax advantages for your home's solar energy systems taxable year cannot exceed $1,000, and the cumulative solar energy credits allowed for the same residence cannot exceed $1,000. The maximum credit a taxpayer may take for all solar energy devices installed in the same residence cannot exceed $1,000 in the aggregate.

For the purposes of the solar energy credit, the following devices (when used for residential purposes) qualify for the credit:

  • Solar domestic water heating systems-collectors, storage tanks, heat exchangers, and piping, valves, wiring, etc., directly related to the solar energy system
  • Solar swimming pool and spa heating systems-collectors, heat exchangers, piping, valves, wiring, etc., directly related to the solar energy system
  • Solar photovoltaic (PV) systems - collectors, batteries, inverters, solar energy system related wiring, including solar PV for RVs used as a residence (end-use appliances, even if they are 12 vdc, are excluded unless they are manufactured specifically for PV applications)
  • Solar PV phones, street lighting, etc. collectors, batteries, inverters, system related wiring (phones, lights, etc., are excluded unless they are manufactured specifically for PV applications)
  • Passive solar building systems - trombe wall components, thermal mass, and components specifically designed for energy gains (dual pane windows, low-e, and other window coatings, etc., are excluded)
  • Solar daylighting systems - those devices and systems specifically designed to capture and redirect visible solar energy while controlling the infrared energy (conventional skylights are specifically excluded)
  • Wind generators -windmill, structure, generator, batteries, controls, wiring, and other components directly related to the wind generator (end-use appliances are excluded)
  • Wind-powered pumps - windmill, structure, pump, pipes, and other components directly related to the wind pump

A solar energy system is limited in how much electricity it can produce due to the amount of sunlight available. However, solar systems can be tied directly into the existing power grid connections to a home, allowing the system to use the solar electricity when available and switch to the traditional power grid energy source seamlessly when necessary. Through a system known as Net Monitoring, Arizona residents can even sell back unused solar energy generated by their home systems to the state through the power grid.
