Stand-alone Solar Photo-voltaic Systems for Off-grid Electrification

Electric energy is necessary to meet the daily needs of the population, as it is used in cooking, heating, irrigation, lighting and others. There are many residential areas far from the public electricity network, hence the importance of solar energy in meeting the needs of these residents. This paper will study the design of a solar photovoltaic system with a capacity of ۱۳۱.۶ kwh. The needs and requirements will be studied first, then a design will be made for The parts of this system, such as inverters, batteries, photovoltaic panels and other parts. The results that we will obtain will confirm that this energy system is able to meet the necessary needs with high efficiency, and will also confirm that it is environmentally friendly in terms of carbon emissions. We will take Tanzania as a case study , the designed system contain ۱۰۸ panels and about ۸kw battery bank to supply the load .
