The exergoeconomic and enviroeconomic analysis of semitransparent and opaque photovoltaic (PV) modules based on different kinds of solar cells are presented. Annual electricity and net present values have also been computed for the composite climatic conditions of New Delhi, India. Irrespective of the solar cell type, the semitransparent PV modules have shown higher net energy loss rate ( ) and net exergy loss rate ( ) compared to the opaque ones. Among all types of solar modules, the one based on c-Si, exhibited the minimum and . Compared to the opaque ones, the semitransparent PV modules have shown higher CO2 reduction giving higher environmental cost reduction per annum and the highest environmental cost reduction per annum was found for a-Si PV module. 1. Introduction In this era of advanced technologies the demand of energy is increasing day by day. The sources of energy are very limited and are running out very rapidly. Emission of greenhouse gases from the fossil fuels is another major concern as it is causing the global warming [1]. Therefore, the renewable sources of energy are developed which have no harmful effects on our delicate environment. To reduce the impacts related to processing of any energy source the efficiency of energy plants should be improved and such studies are done by exergoeconomic and enviroeconomic analysis. The exergoeconomic analysis is basically the exergy analysis along with the cost analysis in order to access the performance of the energy systems [2]. It reveals the relative cost importance of each component and provides the ways to improve overall cost effectiveness [3, 4]. On the other hand, enviroeconomic analysis (also known as environmental cost analysis) identifies the options for reducing the environmental impact associated with the overall system [5]. Photovoltaic (PV) energy conversion is considered as one of the most promising renewable energy technology which has the potential to contribute significantly to a sustainable energy supply and to mitigate greenhouse gas emissions. PV systems are free from greenhouse gases emission. Badescu analyzed a heating system of an ecology building and found that a PV array can provide all the energy required to derive the heat pump compressor, if an appropriate electricity storage system is provided [6]. Ozgener and Hepbasli investigated the capital costs and thermodynamic losses in a greenhouse heating system with solar-assisted ground-source heat pump and found a correlation between the capital cost and exergy loss but no relation was established between capital cost
