Micro-Controller based Solar Charger

Micro-controller based Solar Charger is a device that will allow a solar panel to efficiently recharge a DC battery. This is accomplished by operating the solar panel at an optimal power level regardless of the battery voltage. The controller will vary the voltage across the panel to find and maintain the maximum power point. The circuitry also monitors the battery voltage level and charges the battery using pulse width modulation techniques. This Project uses natural renewable solar energy for generating the electricity in efficient manner thus creating pollution free world termed as "GREEN ENERGY" power generation concept.

The device consists of a boost DC-DC converter, a microcontroller, a current sensing microchip, a Liquid Crystal Display for data output, and a serial computer interface for programming and data collection at the initial stage to dump a small C-program into microcontroller kit PIC16F877.

This report outlines the design and performance of a solar electric charge controller and portable power supply, an extremely portable device which recharges electronic devices. Along with a solar panel, this device employs microprocessor based control which continuously monitors the power output of the solar panel to deliver the maximum electric power to the batteries. This report contains circuit diagram, block diagram, complete working of the project and microcontroller programming for your help.
