Performance Analysis of an Existing BIPV System for Indian Climatic Conditions

In this communication, an attempt has been made for evaluating the performance of an existing BIPV system for Indian climatic conditions, considering four weather conditions (a, b, c and d type) for five different cities (New Delhi, Bangalore, Mumbai, Srinagar, and Jodhpur) of India. In this paper, first solar radiation is calculated on inclined roof (30o), south, east and west facades (90o) of the building and then fourteen different possible series and parallel combinations of PV integrated air ducts mounted on roof have been considered for the evaluation of thermal and electrical gain. It is found that, the average electrical efficiency of the system is 9.64%. Annual thermal and electrical gain obtained for the best combination (11 ducts are connected in parallel each having three PV modules) is 13.42 MWh and 4.38 MWh respectively for New Delhi condition. It is a self sustainable system where electrical energy is used for lighting purpose and thermal energy is used for space heating and drying.
