An On Grid Solar System Built on Residential House Roof

his paper presents an analysis of the (5kW) solar system connected to the grid. This system is designed to feed a residential building with a total daily load of 22870 Wh/day, and the system is installed on an area of from the ceiling. The system contains 10 panels Trina solar 500Wp type connected to each other in series. A 5kW inverter from GoodWe, and 12 of 50AH Lead acid batteries belonging to pylontec that connected to each other in series to store the energy generated by the panels in the daytime and use it later. The helioscope software is used to see the available area of the roof to determine the most appropriate place to install the panels, and PVsyst7.2, which analyzes the project and concludes the results related to the project for development and improvement. The system produces about 8178 kWh per year with an estimated performance rate of 67.9% and the normal daily production of the system is 4.14 kWh, while the loss resulting from the panels is estimated at 1.42 Kwh/day. The project also has an added value as it is considered environmentally friendly as it emits carbon radiation of about98.1????co2.
