Carbon Credits Earned by Hybrid Photovoltaic Thermal Array

C. S. Rajoria, Sanjay Agrawal, and Arvind Tiwari

In this paper, a study has been carried out to evaluate carbon credit earned by hybrid photovoltaic thermal (PVT) array. The study has been based on overall thermal energy and exergy output of PVT array. The hybrid PVT array is a proposed system consisting of 36 hybrid PVT modules connected in a series and parallel combinations. The annual energy and exergy gain has been evaluated by considering four types of weather conditions (a, b, c, and d types) of Bangalore. This paper gives the total carbon credit earned by as per norms of Kyoto Protocol Bangalore climatic conditions. We have found that the total carbon credit earned by hybrid PVT array annually in terms of thermal energy is Rs. 1.34 lakhs and in terms of exergy is Rs. 0.61 lakhs, respectively. The total annual monetary gain in terms of overall thermal energy gain and overall exergy gain comes out to be Rs. 3.83 lakhs and Rs. 1.75 lakhs, respectively.
