In this paper, a PCM storage unit for a solar cooker was designed and developed to store solar energy during sunshine hours. The stored energy was utilised to cook food in the evening. Commercial grade acetamide was used as a latent heat storage material. Cooking experiments were conducted with different loads and loading times during the summer and winter seasons. The thermal performance of a solar cooker with the PCM storage unit was compared with a standard solar cooker. The experimental results showed that evening cooking is possible with a solar cooker having the PCM storage unit and is not possible in a standard solar cooker.
