A hybrid solar photovoltaic system can supply homes and all government and private sector buildings with electricity in cities and remote places. Solar PV systems generate emission-free electricity that is stable, safe, noise-free, easy to use and does not require refuelling. It also reduces the use of fossil fuels in power plants and reduces pollutants and greenhouse gas emissions that cause climate damage, Therefore, the current research aims to design and implement a hybrid photovoltaic solar system to provide one of the laboratories of the Department of Physics at the college of education, Mustansiriya University, with electrical energy during a year. The total electrical energy consumed by the loads in the laboratory (devices, lighting lamps and fans) was measured by about 2000 watts. The working hours of the laboratory were estimated at six hours. In light of that, a photovoltaic solar system consisting of eight solar panels with a capacity of 545 watts per panel was designed in standard conditions and a total capacity of 4360 watts. After the design and installation, the laboratory was operated at its total capacity and the power supplied by the panels to the laboratory was recorded during the first daylight until after midday. The results were encouraging, as it was found that the net power processed by the system is about 3500 watts. Therefore, we can conclude that the construction of solar systems is an economically feasible process under the conditions of severe shortage in the supply of electrical energy and the high cost of purchasing electrical energy from the private sector
