A Study of the Importance of Using Solar Pumps for Pumping Water from Deep Wells and Ways to Increase the Efficiency of their Production

Due to the deterioration of world oil prices, it has become necessary to look for alternative sources to provide energy, and among these alternatives is solar energy, as it is one of the most important alternative energy sources that can be used in various fields such as agriculture and other - due to its many advantages, and the geographical position of Iraq has contributed to the development of the use of energy solar panels in the country due to the intensity and duration of solar radiation, and thanks to this feature, our country can cover its needs with energy to fill the gap in most vital areas, and also for use in agriculture, industry where Stand - alone solar pumping systems typically use a Variable Speed Drive to control the electric motor to run at various speeds depending on the available sunshine power.And also The inverter that converts the dc power from the sun to ac power uses the space vector pulse width to feed the motor. Under a constant v/f ratio,where a modulation method is used It controls the motor's power consumption (rather than its speed) in order to adapt it to the available power on the photovoltaic system. The variable speed operation of the motor as a result of solar power's flux increased has an impact on Pump hydraulic efficiency and performance (The electric pump cures) a result, on the yield of water. Because the operating flow is not continuous, this speed control operation has an impact on the well characteristics.
