The chance to use sunlight as a clean source of energy has arisen as a result of a gradual rise in user requests for eco-friendly power sources and severe government laws for their usage, because its production from a renewable, natural, and eco-friendly resource, in this paper, the performances characteristics of the liquid pumping unit were investigated experimentally when running the laboratory pumping rig by photovoltaic power system under various operating conditions. The study checks the best tilt angle to maximize the output energy. Tests have been performed under various tilt angles 45° and 32°, with a sunny weather condition and within a period between (11:00:00 AM to 4:00:00 PM). The experimental results of the work show that the best PV panel tilt angle to produce maximum power output was at 32˚, also, output power was proportional to radiation, increasing the irradiance will increase the output power of the PV panels. In addition, storing energy into the battery was compensate source of power to continue the pump running during reduced solar radiation. The daily output of the solar pumping system varies according to the amount of direct sunlight that falls on the solar panel, that mean with the increased sunlight the water pumping increased about 24.9 %.
