hello everyone. today i'm gonna explain, how to charge your mobile phone using a solar panel so, for this experiment you're gonna need, a solar panel, a voltage regulating circuit, your charging cable, two wires and your mobile phone. now your solar panel is the power source
when the sun rays directly hit on your solar panel, it converts solar energy into electrical energy. the output power you get from your panel depends on the ratings of the panel. in my panel, here, they mentioned it as 3w and it produces maximum voltage of 10v then i have a voltage regulating circuit here, when i give variable voltage supply as input i get regulated output at this end.
as most of our mobile batteries charge with 5v, here in this peice of circuit i'm gonna use 7805 voltage regulator this is the circuit diagram to make a simple voltage regulating circuit here this is my solar panel, it is the variable voltage source here. then i have a diode arrangement like this. these two terminals connected to regulator input and gnd terminals.
and i connect two capacitors like this each of 10uf and 25v then i get my regulated output voltage here which is suitable to charge your mobile now i'm gonna connect two wires to my solar panel and the other ends to the input terminals of the regulator so, my output of this circuit is now exactly 5v and i give it to my mobile
through my charging cable. okay now everything is fine let's keep the panel outside and check what happens
