ABSTRACT

 

Sand is an environment friendly and easily available low cost heat storage material. The heating tests on sand were performed in a small scale photo voltaic and thermal hybrid solar cooker. The performance was observed for constant load and variable input power and for constant input power and variable load. The empty cooker test was performed for comparison. The results were compared and the maximum heat retention was found for 200gm sand at 42 watt input power. Sand can be used as a thermal energy storage material in solar energy devices like solar cooker, solar dryer and solar hot water system.
