A comparative test using a fixed PV and a 1A-3P tracking PV was carried out with two identical stand-alone solar-powered LED lighting systems. The field test in the particular days shows that the 1A-3P tracking PV can generate 35.8% more electricity than the fixed PV in a partly-cloudy weather with daily-total solar irradiation HT=11.7MJ/m2day, or 35.6% in clear weather with HT=18.5MJ/m2day. This indicates that the present 1A-3P tracking PV can perform very close to a dual-axis continuous tracking PV (Kacira et al., 2004). The long-term outdoor test results have shown that the increase of daily power generation of 1A-3P tracking PV increases with increasing daily-total solar irradiation. The increase of monthly-total power generation for 1A-3P sun tracking PV is between 18.5-28.0%. The total power generation increase in the test period from March 1, 2010 to March 31, 2011, is 23.6% in Taipei (an area of low solar energy resource). The long-term performance of the present 1X-3P tracking PV is shown very close to the 1-axis continuous tracking PV in Taiwan (Chang, 2009). If the 1A-3P tracking PV is used in the area of high solar energy resource with yearly-average HT>17MJ/m2day, the increase of total long-term power generation with respect to fixed PV will be higher than 37.5%. This is very close to that of dual-axis continuous tracking PV. The 1A-3P tracker can be easily mounted on the wall of a building. The cost of the whole tracker is about the same as the regular mounting cost of a conventional rooftop PV system. This means that there is no extra cost for 1A-3P PV mounted on buildings. The 1A-3P PV is quite suitable for building-integrated applications. © 2011 Elsevier Ltd.1254692 bytesapplication/pdf[SDGs]SDG7Comparative tests; Continuous tracking; Daily power generations; Dual axis; Field test; Long term performance; PV system; Solar irradiation; Solar PV systems; Solar PVs; Solar-powered LED lighting system; Stand-alone solar PV system; Sun trackers; Sun tracking PV; Sun-tracking; Test results; Electric power generation; Energy resources; Irradiation; Light emitting diodes; Photovoltaic effects; Solar power generation; Solar radiation; Testing; Solar energy; building; cost-benefit analysis; electricity generation; energy resource; field method; irradiance; irradiation; photovoltaic system; renewable resource; solar power; solar radiation; tracking; Taipei; Taiwan10.1016/j.solener.2011.05.001http://ntur.lib.ntu.edu.tw/bitstream/246246/260619/1/2011SE 1A-3P PV test.pdf
