This thesis, aim to design and simulation of a simple but effective charge controller with maximum power point tracker for photovoltaic system. All you need are some materials and tools like a: PCB board, A bottle of Ferric Chloride, A mini drill, A small container, A bottle of thinner and Some p. and input. This controller can determine the solar panel array's optimum amperage and operating voltage and match it with the battery bank.
