Photovoltaic mounting system at the same angle as the latitude of array's location to maximize the annual energy yield of module. For example, rooftop PV module at the tropics provides highest annual energy yield when inclination of panel surface is close to horizontal direction. A study in the tropics showed that the orientation of low-slope rooftop PV has negligible impact on annual energy yield, but in the case of PV external sunshade applications, east façade and panel slope of 30–40° are the most suitable location and inclination.

Alamosa photovoltaic power plant 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 that the amount of land used is large
