Design and Performance Investigation of Proposed Grid-Tied Rooftop Solar PV System

This paper presents the Design and Performance investigation of the proposed 5 kWp Grid-connected Rooftop Photovoltaic solar (RTPVS) power plant at JNTUH College of Engineering, Manthani, Karimnagar, Telangana. The global horizontal irradiance available in Telangana is 1820.3 kWh/m2/year. The system design includes the sizing of the inverter and PV modules. The performance analysis of the proposed RTPVS system has been done through the PVsyst 7.2 and MATLAB software. Based on the simulation results, it is concluded that the designed RTPVS plant generates 7.798 MWh of energy per annum, and the RTPVS system generates 173 MWh of energy during its lifetime. The yearly performance ratio (PR) is 0.818, and the annual capacity utilization factor (CUF) is 0.178. The simulation results also provide the final yield (YF), array yield (YA), reference yield (YR), collection loss (LC), and system loss (LS). The proposed 5 kWp RTPVS system will reduce 124.756 tonnes of carbon dioxide emissions throughout its lifespan.
