Solar tracker for a compact, portable, affordable solar charging unit
We will invent a tracking device that positions a solar panel so that it receives direct sunlight for the entire day. A simple comparative circuit, using two photo resistors, will be used to provide a signal to a transistor H-Bridge which will drive a small DC motor. This small portable tool will be able to charge a battery throughout the day, which can then be used for night time lighting or cell phone charging for people living without electricity.
