Testing the solar cell phone charger.
Solar panel mobile charger circuit.
How to operate this solar battery charger circuit.
Give the connections according to the circuit diagram.
Solar battery charger circuit which we are making is made up of electronic components which are easily available in market as well as online.
Now set the output voltage by adjusting pot rv1 check the battery voltage using digital multi meter.
Now simply use any power cable and connect it to the usb pin of the module and the other end to your mobile phone.
The second design explains a cheap yet effective less than 1 cheap yet effective solar charger circuit which can be built even by a layman for harnessing efficient solar battery charging.
When there is proper radiation the phone will start to get charge.
As shown in the above wiring diagram simply solder the solar panel in parallel and connect them to a boost converter module through a switch.
Connect the negative leg of the battery holder to red positive terminal of the solar panel.
The longer leg of an led is always interfaced with the ve side of the circuit.
You will need just a solar panel panel a selector switch and some diodes for getting a reasonably effective solar charger set up.
Solar battery charger will take the dc input from the solar panel and will regulate the voltage in order to charge the battery from it.
Place the solar panel in sunlight.
