Abstract

One strategy to increase crop yields is irrigation, but not all agricultural areas have access to enough water for this to be effective. Diesel is also less efficient when used to irrigate agricultural land. Developing a solar-powered water pump system is an environmentally beneficial alternative that uses solar energy. Agriculture and food production consume one-third of the world’s energy, which results in greenhouse emissions. Converting from traditional sources to renewables is crucial. Egypt is considered an agricultural country; agriculture is a key sector in the Egyptian economy. In 2021, it contributed 11.83% of the country's gross domestic product (GDP) and accounted for 28% of the total employment. To overcome problems resulting from traditional sources, a complete optimal design of a solar pumping system is carried out in this paper by using PVSyst software to meet the demand for irrigation of farms in Kharga Oasis, which results in an eco-friendly, low cost design whose lifetime span is 25 years. Also, this paper includes monitoring the water level in the storage tank by using a water flow sensor controlled by an Arduino UNO and soil moisture to schedule irrigation time.
