The objective of this project is to design a solar power station connected to the national electrical grid with a capacity of 50 megawatts. This step comes in light of the Egyptian state's expansion of clean energy projects that aim to transform Egypt into an energy center in the region. In general, solar power stations are environmentally friendly stations, as they do not emit carbon emissions harmful to the environment, which makes them the best imagination in the way of transitioning to clean energy and then a clean environment. This book includes in detail the steps for designing a solar power station with a capacity of 50 megawatts, without calculating the losses, which means that this station will produce 65 megawatts, and this station will be installed and built in New Sohag City. The surface area of the project covers 700,000 square meters and the estimated cost of the plan is 2.4 billion pounds. This book includes an introduction to solar energy and its importance, then reviews the details of the design of the station for which this book was written by presenting what we have done of energy loss calculations, as well as voltage and current calculations, methods of installing panels, installation angle, choosing panels, transformers, inverters, single line diagram, as well as protection and simulating the station as well Control it and cash flow Calculations.
