- The use of solar dryer is slowly finding its way for food and other industrial drying in Nepal. Here in, we designed flat plate solar collector to make perfect black body by changing coating material on absorber metal plate with varied inclination of collector plate. The thermal performance analysis of a solar flat plate collector with black painting and selective coating has been carried out using outdoor test. The average thermal efficiency of black painted collector is 42.50% where as for selective coated collector (67.62%) has more than existing collector. In order to supply the sufficient hot air from the collector to the chamber of heating application, the collector are installed at a slop of 45o and 37o facing south and operates in a closed loop mode with average inlet at 25oC to 38oC in Kathmandu valley with the ambient temperature of 24oC to 28oC. The in-depth analysis of this work may provide important guidance for the more rational design and optimization of solar dryer from the view point of collector.
