Photovoltaic system to microgeneration and photovoltaic systems, and the US UL4703 standard, in subject 4703 ""Photovoltaic Wire"". A solar tracking system tilts a solar panel throughout the day. Depending on the type of tracking system, the panel is either aimed directly at the sun or the brightest area of a partly clouded sky. Trackers greatly enhance early morning and late afternoon performance, increasing the total amount of power produced by a system by about 20–25% for a single axis tracker and about 30% or more for a dual axis tracker, depending on latitude. Trackers are effective in regions that receive a large
Alamosa photovoltaic power plant in comparison to the amount of power generated. Alamosa photovoltaic power plant Alamosa photovoltaic power plant, is an 8.22 MWp photovoltaic power plant located in San Luis Valley, Colorado, USA. The power plant was developed by SunEdison, sells all output to Xcel Energy, and was completed in December 2007. The plant occupies of land, and provided enough power to supply 1400 homes in 2008. This made it the largest producer of photovoltaic power in the United States in 2008. Colorado Xcel customers pay approximately 2% more for electricity to subsidize renewable energy projects. The plant has received some criticism, saying
