UTILIZATION OF SOLAR ENERGY FOR DRIVING A WATER PUMPING SYSTEM (original) (raw)
Abstract
Renewable energy sources in general, and Solar Energy source in particular, has the potential to provide energy services with zero or almost zero emission. The solar energy is abundant and no other source in renewable energy is like solar energy. The solar-powered pumping system can be used anywhere but it is appropriate for rural areas which is facing energy crisis. Due to geographical position, sultanate of oman and gulf region has ample sunshine throughout the year which makes it ideal location for utilization of solar energy. Small farms, villages, and animal herds in developing countries require hydraulic output power of less than a kilowatt. Many of these potential users are too far from an electrical grid to economically tap that source of power, and engine-driven pumping tends to be prohibitively expensive as well as unreliable due to the high cost of purchased fuel and insufficient maintenance and repair capabilities. A solar-powered pump is a normal pump with an electric motor. Electricity for the motor is generated onsite through a solar panel which converts solar energy to direct-current (DC) electricity. Because the nature of the electrical output from a solar panel is DC, a solar-powered pump requires a DC motor if it is to operate without additional electrical components. If a pump has an alternating-current (AC) motor, an inverter would be required to convert the DC electricity produced by the solar panels to AC electricity. Due to the increased complexity and cost, and the reduced efficiency of an AC system, most solar-powered pumps have DC motors. DC motor has been used to drive solar energy water pump system. This paper consists of frame of solar water pump, DC motor, pump, solar panel, suction pipe, delivery pipe, ON/OFF control switch and water tanks.

Because the nature of the electrical output from a solar panel is DC, a solar-powered pump requires a DC motor if it is to operate withou additional electrical components. If a pump has an alternating-current (AC) motor, an inverter would be required tc convert the DC electricity produced by the solar panels to AC electricity. Due to the increased complexity and cost and the reduced efficiency of an AC system, most solar-powered pumps have DC motors[2]. Solar-powered pump: will naturally work best on sunny days, which is fortunate because cattle will consume more water on hot, sunny days. But, water is still required on cloudy days. Solar panels still produce some electricity when it is cloudy, bu their output is diminished. To ensure that ample water is always available for livestock, solar-powered wate pumping systems should incorporate storage sufficient to supply water requirements for three or four days. The components comprising a solar-powered pump depend on whether the pumping system is a direct- drive system or a battery-operated system. In direct drive system, solar energy is observed by solar panel which convert solar energy into direct current which drive the DC motor pump through which water is transfer from water source to water storage. In case of battery operated system, solar energy is observed by solar panel which convert solar energy into direct current which is stored in the battery then current supply from battery to DC motor to drive pump through which water is transfer from water source to water storage.](https://figures.academia-assets.com/56828366/figure_001.jpg)
