How to make solar mobile charger at home-latest tips & tricks
We know this very well that the solar panel converts the solar energy of the sun into direct electrical energy. Ever since the solar panel was invented, people are very aware of it and there are also very good products related to solar in the market, such as solar cookers, solar lamps, solar panels etc. Those who are also studying electronics, they will also know that many people related to solar projects are also made, among whom solar mobile charger is also one. So let's talk
single plate price-$.75 to $1
Solar mobile charger converts the sun's energy to a suitable voltage so that the mobile phone's battery can be charged properly, the most important component of which is the solar panel. As we told that it converts solar energy to suitable voltage, then the biggest problem is that solar radiation does not remain the same at all times, solar radiation keeps on changing in the morning and afternoon and in such a way, the mobile charger. The output voltage will also change and this will also damage the mobile battery. So for this we have to stabilize the output voltage of our solar mobile charger so that it gets the same output voltage in every condition and for this we have to use the voltage regulator in our circuit
Many mobile phones also have the option of USB port so that they can be connected to the computer. We are using USB connector on it, if you want, you can also use pins of direct mobile charger.
necessary ingredients:
1). 12 volt 4 watt solar panel
2). 7805 IC (voltage regulator)
3). 100n
4). 10uf capacitor
5). 100uf capacitor
6). USB connector
7). PCB plate
Step1- First of all we have to take solar panel, behind which two wires are connected. The red wire is +ve and the black wire is -ve. We have to take great care of positive and negative.
Step2- Now we have to design the circuit as shown in the picture. From this circuit we get a 5 volt supply at the output. The IC 7805 is a regulator IC that provides a constant 5 volt at the output. Mount all electronic components on pcb and solder and if you also have to check the output of the circuit that there is no problem in our circuit, then applying 10 to 18 volt on input should give us 5 volt at the output.
Step3- Now we have to connect the plus and minus pins of the output to USB or to the pins of direct mobile charger. Connect the solar panel to the input of the pcb and the pins of the charger to the output.
Step4- Now put the solar panel in the sunlight and check the output voltage of the circuit. If the output is coming at 5 volt or even less then your mobile charger is made perfect. Now fit the pcb into the plastic body of a charger and mount the solar panel on top of it. Now you can charge your mobile directly from solar energy. Whenever you keep your mobile charger in the sun, the same way your mobile will start charging.
