Exergoeconomic and Enviroeconomic Analysis of Flat Plate Collector: A Comparative Study Prateek Negi, Ravi Kanojia, Ritvik Dobriyal, and Desh Bandhu Singh Abstract Energy resources and their usage intimately relate to sustainable develop- ment. Solar flat plate collectors are widely used to collect solar radiation for various applications. Many hybrid systems which include flat plate collector integrated with photovoltaic/thermal panel has gone through various developments and analysis based on energy, exergy, and exergy based environment, exergy based economic anal- ysis and shows great achievements for its applications. This presents paper briefly reviews exergoeconomic and enviroeconomic and some performance analysis of a hybrid flat plate collector to be a useful tool in assessing their thermal efficiency, economic aspect and environmental impact.

Solar energy is considered as one of the renewable energy sources and harnessing solar energy with the help of solar thermal collectors and photovoltaic can be found useful for various applications like solar water heating, solar drying, distillation, etc. Flat plate collector is the most common among the solar thermal collectors which absorb solar radiation for heating of fluid which is then supplied to the end-user to satisfy the demand of hot water and is considered to be an alternative to conventional geysers. In order to optimise the system for improved output, various analyses need to be done. For many years thermodynamics and economic parameters are the basis for the anal- ysis of the system [1] because the numerical method may be inadequate to optimize P. Negi · R. Kanojia · R.
