To Study Impact of Array Tilt Angle, Orientation, and Inverter arrangement on Power Output of Rooftop Solar PV Panels for Chandigarh.


The inclination and orientation of a Photovoltaic (PV) module significantly impact its energy yield and power output. Most commonly, the angle of the module is fixed based on the latitude of the site and field experiences. However, this angle may not result in maximum PV panel output Moreover, there is a shortfall in experimental analysis. The performance of 21 PV modules placed in three orientations, namely south, southeast and southwest and at seven different tilt angles in each of three orientations installed on the rooftop of a building in Punjab Engineering College (Deemed to be University), Chandigarh, has been evaluated by using actual measurement data as logged by data loggers installed. The database from July 2018 to June 2019 has been statistically analyzed to examine the influence of module inclination and orientation on its energy and power output. The impact of mutual shading of modules (due to inappropriate row spacing) on power generation and optimal tilt angle values has been analyzed in this work as well. Therefore, recommended optimal annual fixed tilt angle for Chandigarh is 17±2 ° and orientation is South.
