Photovoltaic thermal hybrid solar collector Photovoltaic thermal hybrid solar collector Photovoltaic thermal hybrid solar collectors, also known as hybrid PV/T (PVT) or solar cogeneration systems, are power generation technologies that convert solar radiation into usable thermal and electrical energy. Such systems combine a solar cell, which converts sunlight into electricity, with a solar thermal collector, which captures the remaining energy and removes waste heat from the PV module. These technologies can be more energy efficient overall than solar photovoltaic (PV) or solar thermal alone. Significant research has gone into developing a diverse range of PV/T technologies since the 1970s.. While many collector types have been
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. History of photovoltaic growth The history of photovoltaic growth includes previous forecast and annual deployment figures by country. Most PV deployment figures in this article are provided by
