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.
History of photovoltaic growth using only the most recent report's data. Exchange rates represent the 2006 annual average of daily rates (OECD Main Economic Indicators June 2007)<br>Module Price: Lowest:2.5 EUR/Wp (2.83 USD/Wp) in Germany 2003. Uncited insolation data is lifted from maps dating 1991–1995. Original source gives these individual numbers and totals them to 37,500 kW. The 2004 reported total was 30,700 kW. With new installations of 6,800 kW, this would give the reported 37,500 kW.
