Co2 Emissions Reduction of Photovoltaic Thermal Model Using Variable Flow Rate Values

Abstract

In this paper, Co2 emission reduction of Photovoltaic Thermal (PVT) model using variable flow rate values has been examined and evaluated for seventy-three different Photovoltaic (PV) coverage area cases of PVT (between 20% to 80%). A data set of weather conditions of a city in Canada over one year is used for this study. Co2 emission reduction is investigated for each month for the different cases in this work. For minimizing Co2 emissions, the percentage of PV coverage area values for each month is determined. To maximize the annual Co2 emission reduction, specific PV coverage area values are carefully chosen for each month using variable flow rate. Results show that the annual Co2 emission reduction can be maximized by using adapted (dynamic) PV coverage area values compared to the conventional (static) PV coverage area values of the PVT system during a year. The fitted-curve function is obtained which evaluates the Co2 emissions reduction for each month at different PV coverage area ratio.
