Calculation of energy flow and carbon credit earned in roof integrated photovoltaic thermal system

Abstract

In the current paper, analysis has been carried out for a system that has been created on a roof specially designed for semitransparent thermal system. A thermal model has been designed considering quasi-steady state condition to predict the solar cell temperature, tedlar and the temperature at the outlet of duct and room temperature air from room is used as design and electrical parameters. Calculation has been done for electrical and thermal energy outputs at respective places. Finally a comparison has been made between conventional and present system and cost calculation has been calculated. It has been found that for the same system there would be a loss of 6.13 Ton amount of CO2 and a saving of Rs 3,41,390 for 30yrs for the same amount of generation.
