PV-Solar Power Generation in Educational Institutions

The PV solar system on the rooftop of buildings is a good source of renewable electric energy. Iraq has very large number of educational institutions with large non-invested rooftop with shortage of electrical energy supply. The present work aims at construction a simulation for PV-System action installed on rooftop of educational institutions in Baghdad using Green Power Solution (GPS) and PV-Syst programs. Based on the surface area of the schools’ roofs, the GPS program estimated three main PV-Systems which can be carried out, 63kW, 50kW, and 30kW in order to supply the electric power to selected school. Due to allocating few hours for school’s studying time along the year, the suitable PV-System is on-grid connection. The results indicated that the annual system performance ratio is 81.9% and the annual output power of these systems were 111.0 MWh/year, 88 MWh/year and 51.4 MWh/year respectively, 19.3MWh/year of them was consumed for this school and the rest is a feedback for grid. This green generation reduced the amount of emission CO 2 by 73.981 tons, 62.216 tons and 36.3398 tons per year for systems 63kW, 50kW and 30kW respectively. The results also appear that the initial capital cost of each system can be recovered during the first six years of system operation.
