Photovoltaic system the outer edge. Electrically connected and mounted on a supporting structure, solar modules build a string of modules, often called solar panel. A solar array consists of one or many such panels. A photovoltaic array, or solar array, is a linked collection of solar modules. The power that one module can produce is seldom enough to meet requirements of a home or a business, so the modules are linked together to form an array. Most PV arrays use an inverter to convert the DC power produced by the modules into alternating current that can power lights, motors, and other loads.
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.
