Objective:
The objective of this project is to control solar panel position depends upon the sun light.
SYNOPSIS:
Scope:
Now a day’s power demand is increased due to this power failure happen many time. This project is designed to provide the solution for this power loss.
Brief Methodology:
This project is designed by following blocks,
Microcontroller.
ADC.
LDR
Solar panel.
Motor.
This project is designed with solar panels, LDR, Amplifier, ADC, Microcontroller and Driver circuit along with motor.
Solar panel consists of number of silicon cells, when sun light falls on this panel it generate the voltage signals then these voltage signals given to charging circuit. Depends on the panel board size the generated voltage amount is increased. Naturally sun direction is varied per hour. In order to get the efficient voltage the solar panel position has to very as per the sun direction.
In this project two LDR is fixed in the solar panel opposite side. LDR is nothing but Light Dependant Resistor which varies the resistance depends on the light fall. The varied resistance is converted into voltage signal. Then the voltage signal is given to amplifier circuit in order to amplify the voltage signal. The amplified voltage signal is given to ADC.
ADC is nothing but analog to Digital Converter which received the two LDR voltage signal and converts the input analog signal to corresponding digital signal. Then the converted digital signal is given to microcontroller. Here the microcontroller is the flash type reprogrammable microcontroller in which we have already programmed. Microcontroller received two digital signal from the ADC and compares that signal. This signal is varied as per the sun light. The microcontroller displays the corresponding information on the LCD display and activates the driver circuit for motor. The motor is attached in the solar panel, this ca rotate in both forward and reverse direction. Through this way solar panel position is changed as per the sun direction. By using this project we can the efficient voltage from the solar panel.
