3 1 Overview of Flat Plate Collectors

The flat-plate systems normally operate and reach the maximum efficiency within the temperature range from 30 to 80 o C (Kalogirou 2009) however some new types of collectors that employ vacuum insulation can achieve higher temperatures (up to 100 o C) Due to the introduction of selective coatings the stagnant fluid temperature in flat-plate collectors has been shown to
