One reason that solar cookers have not gained widespread acceptance is because of unavailability of low cost good reflective material which can be used to make efficient solar cookers. Conventionally used reflective materials such as silvered glass mirror has drawback of higher cost, fragility and inflexibility which limits its application in solar cookers. A critical task in construction of domestic use solar cookers is to find a good cost-effective reflective material. Not only that, it is a difficult to guess which material is better than the other among different types of reflective material available in the market. In this work an attempt is made to search and evaluate best available reflective materials in the market which can be used for making domestic use solar cookers. During this work, a solar concentrator was made using a parabolic dish and was tested with four different types of reflective materials, namely One-way solar reflective mirror, Vinyl car wrap, Mirror wall sticker, and Aluminium foil tape. These reflective materials are compared with each other to find the best material on the basis of its reflectiveness, cost, and ease of application. Experiment suggest that Vinyl car wrap and Mirror wall sticker are about 1.8 times better than Aluminium foil tape as far as reflectivity is considered. But since Vinyl car wrap cheaper than Mirror wall sticker, we can say that it is the most suitable reflective material for application in domestic solar cookers.
