The project aims at developing a system which makes use of wind and solar energy for charging of mobile phones and laptop. Wind and solar energy are treated as renewable source of energy. The system also uses inverter to charge the laptop. People usually run out of phone and laptop charging while travelling. At such times there is literally no way of charging your phone laptop in an outdoor environment. Well, we hereby solve this problem with a green energy system using a dual power generator solar plus wind energy charging system for mobile phones and laptop. The project makes use of a wind turbine and solar panel. Using these two renewable energies, we can charge a rechargeable battery which supplies power to 2 relays ie., R1 and R2 respectively. In the case of R1, which when turned on through Keypad switches ON the inverter thereby switching ON the laptop charging point. In case of R2, which when turned ON, switches ON the mobile charging sections to charge a mobile phone at a time. In this we are using lm2596 voltage regulator to provide the 5vdc output to the Arduino. We use Arduino UNO Microcontroller in this project. This is the main controlling part of the system which is interfaced to keypad and LCD also other than the relays section. Keypad is to enter which charging section the user needed either the mobile section or the laptop section and to enter the amount of time the charging must take place. LCD is used for visible alert to know which charging point is being selected and for what amount of time that charging point is ON.

 

Features of this project:

1. Using renewable energies solar, wind.
2. Storing wind and solar energy into the battery.
3. Enables us to charge 2 mobile phones and a laptop
4. Able to enter the selection of charging point and for the required amount of time.
