PROJECT DESCRIPTION

The project is designed for converting  the solar energy into electrical energy. The solar panel made with photo-voltaic cells convert solar energy into electrical energy. This energy is stored in batteries during day time for utilizing the same during night time. This project deals with a charge control mechanism for over charge, deep discharge and under voltage protection of the battery and overload too. 

In this project solar panel is used to charge the battery. A set of op-amps are used as comparators for continuously monitoring the panel voltage, load current etc. Indications are also provided by the LEDs where green LED for fully charged battery while a set of red LEDs to indicate under charge, overload and deep discharge conditions.

Charge controller also uses MOSFET as power semiconductor switch to ensure cut off  of the load in low battery or overload condition. Whenever the battery gets fully charged then solar energy is bypassed to a dummy load with help of the transistor that protects the battery from getting over charged.

Further the project can be enhanced by using microcontroller and GSM modem to communicate the status of the system to a control room via SMS.

Q & A
Q:  Which kind of inverter is used in this project?
A:  Any inverter can be used as a solar inverter with just this charge controller.
Q:  Can I use a higher rating Solar Panel?
A:  Yes a higher rating solar panel can be used, but limited up to 6V, 20W
Q:  Can I use a larger battery to charge it?
A:  Yes a larger battery can be used, but limited to 7AH
Q:  How the load can be changed from fan to lamp?
A:  About 6W-10W lamp can be connected in place of fan

Great idea, well made, but way too expensive for what it is!
