Solar Photovoltaic Systems on Public Schools Buildings: A Case Study in Palestine

Abstract

Renewable energy exploitation has proved its promising characteristics in sustainably securing energy needs. This work is a comprehensive assessment of the potential of renewable penetration in securing electricity needs in Palestine. Methods of assessment have been determined based on solar potential. Al-Dahriya secondary school in the south Hebron directorate of education was used as a case study, where these building have low working hours all over the year, which will increase the total income of the annual solar energy. AutoCad software simulation program was used to draw the rooftop of the school. The powerful HOMER Pro R software was used for the simulation processes of the PV system and its requirements. Results showed that, the rooftop could accommodate 144 panels, with 57.16 KW. This system will produce 92,866 KWh every year, which could be an input of 5.12% of the total annual power consumption in Palestine if this system installed on every school in Palestine, which are in total 3074 schools. Due to the number of working hours and low energy consumption in schools, the payback period of the project will be 4.38 years. The income of the surplus when installing such project on all schools in Palestine will be around 43 million USD to the Palestinian Treasury every year after the payback period.

Performance analysis and effect of pandemic condition on utility grid connected PV system

“…-Masrur et al [6] analyzed techno-economic evaluations like net present value (NPC) levelized cost of energy (LOCE) for optimally tilted PV system located at Hatiya, Bangladesh, and concluded that the power exchange cost is lower than the value of the derating factor. -Alsamamra and Shoqeir [7] using HOMER Pro software simulation of a 57.16 kW rooftop PV system with 144 panels and concluded that due to low working hours and less energy consumption the payback period is 4.38 years. -Yadav and Bajpai [8] analyzed the performance analysis of a 5 kW rooftop solar plant in northern parts of India has an annual average reference yield of 5.23 kWh/kW/day, array yield of 4.51 kWh/kW/day and final yield of 3.99 kWh/kW/day.…”

Climate Change Mitigation Approach for School Buildings in Palestine: A Combination of Energy Efficiency and Energy Production

“…The installation of PV systems on the school buildings rooftop in Palestine proved to be economically encouraging with a payback period of fewer than 5 years, besides its environmental and increasing energy security benefits [31]. A study by Alsamamra and Shoqeir found that installing PV systems on the rooftop in all the schools in Palestine can provide around 5% of the total annual energy consumption in Palestine [32]. Besides, the school buildings provide a potential environment for investment in PV systems due to the larger roof area for each building, and the limited use of electricity in schools compared to the residential buildings.…”
