Performance evaluation of solar flat plate collector

Flat Plate Collectors (FPC) is widely used for domestic hot-water, space heating/drying and for applications requiring fluid temperature less than 100oC. The absorber plate of the FPC transfers solar energy to liquid flowing in the tubes. The flow can takes place due to thermosyphon effect or by for...
