- ItemSecuring electricity needs from rooftop solar PV systems: A case study of three schools in Beit Fajjar-Bethlehem-Palestine(Al-Quds University, 2023-12-23) Ali yousef Taqatqa; علي يوسف طقاطقةIn Palestine the energy sector suffers due to the various policies of the Israeli occupation, and the energy sector in Palestine is considered expensive as a result of the dependence of the industrial sector in Palestine directly on electricity, so it is necessary to resort to sources of renewable energy as a new source of energy. Solar energy systems are one of the most important renewable energy sources in the world, and the countries of the world today seek to exploit this method in securing their energy needs. To exploit solar energy must be available the spaces on which solar projects should be placed, hence the idea of this study in exploiting the roofs of almost empty schools in the generation of electricity through solar photovoltaic projects, because schools close their doors about 180 days a year, and have a period of working a day with a maximum of 7 hours, as well as the low energy consumption, all of these stimulate the exploitation of these spaces available on school roofs to generate solar energy. In order to study the feasibility of exploiting the roofs of buildings to generate electrical energy, in this study, PVsyst software was used to build and design three photovoltaic systems on the roofs of three schools of different area and amount of consumption, and then calculate the income and payback period. The total area used in the three projects combined was about 901 m2, the total number of panels used was 345 panels, and the capacity of the three systems 189.75 Kw, so the annual production 314681 kwh. From the electricity company’s readings, it was found that the three schools consumes an amount of electricity amounting to 39401 kwh, so the annual surplus amount from the three schools is about 268653 kwh, and its annual selling price reaches 150445.68 NIS. The number of schools in Palestine 3075 When this project is implemented on the roofs of these schools, they will produce 322.54 Gwh, which represents 4.98% of the annual consumption of electricity in Palestine, in addition to the schools’ energy consumption, which represents 0.6% of the annual consumption. The total cost of the project will reach 816 million NIS with a payback period of about 5 years, and the total annual income from selling the surplus electricity for schools will be 154 million NIS. This will help reduce the bill for purchasing electricity from Israel, as it will save the Palestinian treasury an amount of 150. 5 million NIS after about 5 years
