Demystifying The Solar ModuleFranklin, Ed; Univ Arizona, Coll Agr & Life Sci (College of Agriculture, University of Arizona (Tucson, AZ), 2017-08)The adoption of solar photovoltaic (PV) energy systems to serve as an energy source for residential, commercial and agriculture applications is growing. Early use of solar PV energy as an alternative energy source to fossil fuels became popular in the 1970’s during the rise of the environmental movement. The cost of solar power in 1977 was $76.00 per watt. A combination of factors including public awareness, demand for solar, availability of product and service, and improving technology has dropped the cost per solar watt. In 2015, the cost of solar power was $0.613 per watt (Shahan, 2014). Energy rebates offered by local, state, and federal agencies has made the adoption of solar energy more affordable.
Solar Photovoltaic (PV) Site AssessmentFranklin, Ed; Univ Arizona, Coll Agr & Life Sci (College of Agriculture, University of Arizona (Tucson, AZ), 2017-08)An important consideration when installing a solar photovoltaic (PV) array for residential, commercial, or agricultural operations is determining the suitability of the site. A roof-top location for a residential application may have fewer options due to limited space (roof size), type of roofing material (such as a sloped shingle, or a flat roof), the orientation (south, east, or west), and roof-mounted structures such as vent pipe, chimney, heating & cooling units. A location with open space may utilize a ground-mount system or pole-mount system.
Types of Solar Photovoltaic SystemsFranklin, Ed; Univ Arizona, Coll Agr & Life Sci (College of Agriculture, University of Arizona (Tucson, AZ), 2017-08)Solar energy systems can help Arizona individuals, families, and businesses achieve energy conservation goals beyond the adoption of energy-efficient appliances, and LED bulbs. Which type of system is the best? Knowing which system to select is the first important question. This factsheet will focus on solar photovoltaic energy systems. The term photovoltaic refers to the conversion of light energy to electricity.
