Performance advantages of two-axis tracking for large flat-plate photovoltaic energy systems
Abstract
Daily and annual energy-delivery performance is compared for large-scale fixed-array and two-axis tracking photovoltaic generating systems similar to the ASI Project at Lugo, CA. Systems of equal peak-watt rating and systems of different sizes but equal annual energy output are compared in the Lugo setting. Site sensitivities are discussed. For the site studied, it is observed that a fixed-array system would use about 40 percent more modules than a two-axis tracking system, for equal annual energy.
