The utilization of solar energy has been used over a long period of time. The applications like air heating and water heating are the main usage of solar energy and it is globally accepted and still utilizing in many countries. Still various types of research work are in under progress through worldwide to improve the solar gadgets to work more efficiently. It has been evident that every solar gadgets need a little bit of improvement in order to perform well. The better solution for the improvement of flat plate collector is the cavity collector configuration. The experimental analysis of a solar cavity collector has been presented in this research paper. The experimental analysis on solar cavity collector (SCC) has been conducted to determine its optimal efficiency under various conditions. A parametric analysis has been carried out to find out the optimal performance parameter and effective utilization of the solar energy inside the cavity collector. Various lengths to diameter ratios (L/D ratio) has been experimented viz., 40, 50 and 78.74. The gadget has been tested by changing the mode of flow as parallel and serpentine type. Comparisons have been made for its optimal performance with circular and rectangular type cavity cover. Also the collector has been tested with 5 and 7 number of cavities for the same L/D ratio of 78.7. It has been tested at various mass flow rate of water such as 0.002, 0.0025, 0.003, 0.0035, 0.0047, 0.0067 kg/sec to investigate its optimal performance. Experimental results show that L/D ratio of 78.7 gives better results than the others.
