The pumping of water from solar energy depends on the availability of three basic elements for its success. These elements include adequate solar radiation, water collection tanks, the number of panels, and the orientation of the array, especially in the winter season. There are auxiliary factors that include the movement of clouds in the sky because it causes instability in the pumping process and thus productivity, as well as the availability of the public network as an auxiliary element in the winter because the modern hybrid devices contain two sources (sun - public network). In this study, the solar radiation was measured in two locations and two experiments were conducted on the hybrid system, including the operation of a 1500 watt submersible pump on the network and the operation of a 1500 watt pump on the (solar array only). Submersible pump in the underground well (90 m depth) with a capacity of 1500 watts. And that was done through a solar array with a capacity of 2700 watts, and a voltage of 350 volts DC was obtained, which is within the service voltage range of the hybrid control device, and the output voltage was set to 240 volts variable current, so that it was possible to operate the submersible pump for the well with a depth of 90 meters with a productivity of 20 liters / minute. It was noted that the solar radiation was under the influence of the cloud movement, which caused the instability of the operation of the 1500-watt well pump. The operating experience of using storage units for electrical energy for small and medium pumps showed that it can depend on three sources (sun - network - electrical energy storage units) with stability and reliability.
