Design and Implementation of PWM Charge Controller and Solar Tracking System

The main object of this paper is to report and present the design and implementation of PWM based solar tracking system. Solar tracking allows more energy to be produced because the solar array is able to remain aligned to the sun. Our final goal is to develop an automatic tracking system which will keep the solar panels aligned with the sun in order to maximize eciency. In this project we are trying to increase the solar power production and safety of solar power system. This project has two deferent parts those are solar tracker and PWM charge controller. We have tried to make a tracker which can track more sun intensity for the solar panel. For using the solar tracker system we can produce more energy than the analog solar system. In this project we have also tried to generate more eciency than the other solar system by the PWM charge controller. Without charging the battery from the solar panel, the PWM charge controller made by us gives various kinds of protection like as night prevent current protection, load control, over charge control, show battery charge level and short circuit protection.
