Abstract: Solar Roof tops are being progressively used worldwide now a days to install solar panels to generate electricity. One such step has been taken by S.R.K.R Engineering College to generate power through solar roof tops by installing a 33KWp On-grid solar power system (Latitude 16.54° N and Longitude 81.50° E) during April-2016. This grid connected PV system is installed at an area of 345 sq. m and the PV modules are tilted at an angle of 18° on the top of a 3 staired building. This paper analyses the Performance of a 33KWp On-grid photovoltaic system which is monitored between Jan-2019 to Dec-2019. Some part of electricity generated by the system is consumed by the college and the remaining power was fed in to the state grid. The tariff for the grid connected system is based on the energy consumed from the grid and the energy supplied in to the grid. The data is collected from the Data-logger of the inverter which is having an IP address. This data is collected according to the IEC protocol which suggests to collect the data for every 15 minutes. The data is collected from the inverter in this format and is stored as a csv file every day. This data along with the meteorological data collected from the coordinates of the site are analyzed by using pvsyst simulation software. The performance of this system is found for the third year in operation. . The analysis of the PV system has been done to enumerate its performance at each and every component and thereby develop solution to mitigate the problems. The different parameters including efficiencies of panels, inverter, array’s initial yield, final array yield, and the performance ratio of PV system are analyzed.
