Performance comparison of building integrated multi-wattage photovoltaic generators mounted vertically and horizontally

This paper deals with the simulated study that is carried out using PV-Online tool for analyzing the performance of building integrated multi-wattage photovoltaic generators (MWPVG's). Si-mono and Si-poly type MWPVG's were considered for mounting on a building in vertical and horizontal manner. MWPVG's represents DC PV generators whose rating is in kWp. In this study, 1 kWp, 2 kWp, 5 kWp and 10 kWp MWPVG's were considered and the same were used for simulation in vertical and horizontal mount configurations for four different Indian cities: Bangalore, Calcutta, Hyderabad, and Srinagar. Performance of the considered MWPVG's for each location was analyzed based on the obtained results like AC grid feed-in energy in kWh, performance ratio (PR's) and grid feed-in payment in Rs./kWh. Grid feed-in payments were estimated as per the current tariff rates fixed by respective government bodies of the study location.
