Due to the technological advancement and population and explosion, the world’s demand for energy has a rapid growth. So a renewable energy source that is cost-effective, reliable and everlasting must be opted to meet the future energy demands. There are many renewable energy sources out of which solar energy is free of cost. It is also suitable for long-term issues. Due to energy’s high demand, the solar industry is developing all over the world. Many other energy sources like fossil fuel are expensive and also have limited applications. It has become a tool to sustain the underprivileged people’s life. It also has a great part in developing in the economic status of various countries. Solar industry is the best energy source than other energy sources and a solution to meet the future energy demands as it has various benefits. The various benefits include capacity, cost-effectiveness, accessibility, availability and efficiency.  Based on the interest and above view point researcher selected the area of solar energy. This paper on “Designing and Evaluating the Performance of Solar Powered Iron Box” briefly describes the design and performance of the solar powered iron box. A study was conducted in Coimbatore city among four hundred samples using interview schedule for which questionnaire was developed which entailed socio-demographic profile of the participants, solar devices used by them, limitations faced, other device they would like to have operated on solar power etc. During the study it was revealed that majority of participants opted for solar powered device

In India, most land is used for agricultural purposes which produces semi- finished products or goods. Groundnut is also one of the agricultural semi- finished goods. Groundnut is grown on small scale farmers in developing countries like India. The average kernel price is approximately twice the price of pod. . Lack of groundnut processing machines, especially groundnut Sheller, is a major problem of groundnut production, especially in our country India. In the beginning the peanuts were separated from its shells by the workers. They simply decoct the groundnut by their hands and separate the peanuts from its shell. The output from this method was very low and it does not fulfill the market demand because it was a very timeconsuming process. Regression models that could be used to express the relationship existing between the Sheller performance indices, pod moisture content and feed rate were established. This paper describes the design and fabrication of various components of groundnut Sheller machines. Hence in this design of various parts are necessary, and design of various parts due to which the design quality of those parts will be improved. Overall, this project involves processes like design, fabrication and assembling of different components etc.
