9 Solar Arizona SRP has installed the latest in Photovoltaic Panels, including PV shingles (center house) that match the color of the roof. Preliminary estimates indicate these systems will produce one (1) KW of electricity, which should be sufficient to supply 20-60% of the required power, depending on the season.

11 Solar Arizona This home (bottom) in Johnson Ranch Estates in the East Valley has four 300-watt panels that cover approximately 104 square feet of the roof surface. The array on the adjacent building (top) consists of watt panels that covers 108 square feet of rooftop. Click here for larger image

15 Solar Arizona As these homes demonstrate, the solar industry has made great strides in the past decade to integrate solar systems into the roofs of homes. This new generation of solar systems have quietly found their way onto rooftops throughout Arizona, offering an aesthetically pleasing alternative to the systems of the 1980s.

17 Solar Arizona "What we're literally doing here is building a small power plant one house at a time," said John Wesley Miller, developer/homebuilder of the 99 high-tech solar homes in Tucson's historic Armory Park neighborhood. Homes include solar water heating and solar electricity. Click here for larger image

19 Solar Arizona A 2.4 kw PV system being installed on a roof in a Scottsdale subdivision. The system is one of a growing number of grid- connected homes in urban areas that are taking advantage of utility rebates and tax credits to finance systems with favorable payback terms.

21 Solar Arizona The 2.4 kW PV system on this Scottsdale house is eligible for a $4,800 utility company rebate and a $1,000 state tax credit. The Arizona solar tax credit is 25% of the system cost up to a maximum of $1,000. The tax credit (ARS ) has been in existence since Click here for larger image

22 Return to previous slide

23 Solar Arizona This 1 kW PV system in Scottsdale consists of watt solar panels. The house is grid-connected, thus the homeowners can sell solar generated electricity back to the utility company if the house does not have a demand for the electricity at the time it is produced.

25 Solar Arizona This Prescott house does not stand out from the others in the neighborhood, however it is different. The house collects rainwater for all household purposes. It utilizes solar electricity and solar water heating. It is built with certified sustainably harvested and local 'leftover' wood and utilizes cast earth and strawbale construction. Click here for larger image

26 Return to previous slide

27 Solar Arizona Designed by Prescott College student Brad Tito, the house uses a fraction of the energy the previous house on the same site consumed. That house was about one-quarter the size of the new one but consumed more than four times the energy. This past January the utility bills were $22 for gas (used for cooling and water heating) and $4.23 for electricity. Click here for larger image

29 Solar Arizona Solar isn’t exactly a new phenomenon, Arizonans began building solar homes (passive and active) in the 1970s in response to the Energy Crisis. This home, in Flagstaff, is just one of many built throughout the state in the late 1970s. The passive solar features provides more than 55% of the home’s heating needs. Click here for larger image

31 Solar Arizona Another example of the alternative building methods employed during the 70s and 80s, this Tempe solar home is 68 percent earth covered or earth bermed. Built in 1981 this home’s features include a rock bed for heating and cooling, an attached greenhouse and a solar domestic water heating system. Click here for larger image

33 Solar Arizona This 1850 square foot residence in Prescott is made of Poured Earth and features solar for all electrical needs and hot water. The home also uses passive solar power and its 16" thick thermal walls for both heating and cooling. Backup heat is provided by a radiant floor and a high efficiency wood stove.

35 Solar Arizona Solar energy is a great way to heat swimming pools. Using the existing pool pump, water is diverted to the solar system. It then passes through the collectors, where the water is heated by the sun’s radiant energy. Next, the water is returned to the pool to repeat the cycle until the pool has been warmed.

37 Solar Arizona In many cases, solar rooftop systems are barely noticeable. Planned communities and Homeowner Associations, once a barrier to growth in the solar industry, have dropped their objections to rooftop systems. ARS protects the rights of homeowners to install and use solar systems on their property. Click here for larger image

39 Solar Arizona Solar energy has long been used in areas of the state that are not serviced by the electric utility company. This off-grid solar house on the Navajo Reservation was constructed by the local coal company when the original housing structure had to be removed due to mining activity.

Middle -- From the west, massive wing walls protect windows from direct sun and create shade spaces outdoors in the park. Bottom -- At the north energy clear insulated roof panels provide day lighting for the northern portions of the library. Click here for larger image
