An investigation on selection and validation of suitable material to a roller of an automated solar panel cleaning system using DEAR algorithm.

This paper discusses the application of Data Envelopment Analysis based Ranking (DEAR) algorithm in selection of materials for the rollers which moves across for cleaning the solar panel automatically. Selecting suitable materials for roller used in the developed automated solar panel cleansing system, indeed, the selection of material for any part in a design process requires substantial knowledge in the process. Even having required knowledge in the domain, it is often requiring some guidance or reference for providing the justification after selecting the materials for the product. In this sense, in this work, the DEAR algorithm one the multi criterion decision making algorithm is used as guiding algorithm to identify the suitable candidate material for the rollers. Algorithm helps in selecting the material which considered to be as an effective material from the group of available materials which are suitable for adapting as the materials for rollers. For the algorithm to work, the various properties like weight, friction coefficient, cost which are considered as important properties for roller to work efficiently were presented to the algorithm and based on the same, the algorithm suggested the best material for the rollers.
