Rooftop photovoltaic power station Rooftop photovoltaic power station A rooftop photovoltaic power station, or rooftop PV system, is a photovoltaic system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure. The various components of such a system include photovoltaic modules, mounting systems, cables, solar inverters and other electrical accessories. Rooftop mounted systems are small compared to ground-mounted photovoltaic power stations with capacities in the megawatt range. Rooftop PV systems on residential buildings typically feature a capacity of about 5 to 20 kilowatts (kW), while those mounted on commercial buildings often reach 100 kilowatts or more.
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
