The Flat-Plate system comprises an insulated, weatherproof box containing a dark absorber plate under one or more transparent or translucent covers. Water or conducting fluid passes through pipes located below the absorber plate. As the fluid flows through the pipes it is heated. This collector, although inferior in many ways to evacuated tube collectors, is still the most common type of collector in many countries
