How to make a solar phone charger

Solar technology has become far more advanced and sophisticated since it has started to perform in various different fields. It can be seen that Solar power is accessible and convenient and allows you to charge your daily usable items as efficiently as other power sources can do so.

You can make use of the Solar energy for charging your UPS batteries, running your appliances and charging you mobiles as well. While we can easily see you can find readymade solar chargers for various appliances and devices, you can also think of building a solar power charger for your mobile devices on your own. You might think it may need a certain amount of knowledge to make up the circuits, but trust me it is not as painstaking as it seems to be.

Let’s have a look and see the way to make solar phone charger

Things you may need

  • 9 of the 0.5 volts solar panels (simple solar panels with no extra layers or coats)
  • A foam board to fix the solar panels
  • A paper cutter
  • Scale
  • Glue gun
  • USB cables 2-3

Performance

Step 1

At first, you will need to cut the foam board according to the appropriate size that can accommodate three solar cell in a row per row and makes three columns and 3 rows comprising of 9 cells on the board. You can estimate the size and cut it properly.

Step2

After the first step, you need to poke the proper holes for the wires to pass through to the other side of the board. You may place the cell on the board and poke holes on each side where the positive and negative wires are attached.

Step 3

Arrange the solar cells so that they can be connected in a series circuit. To make sure you make the connection in the correct way, you may place the cells so that each positive is attached to the negative wire of the other cell. This will result in the series circuit of the cell.

Step 4

Make the holes bigger and put the positive and negative wires through the holes to the other side of the board making it sure that they are going to be connected in series. You should place the cells properly going through positive-negative connections.

Step 5

After attaching the wires in series you will get two free ends one of the positive and the other will be the negative one. Glue the cells and the wires to keep them in their place. We are using 9 cells of .5 volts each to complete the total of 4.5 volts which is the required voltage to charge the mobile devices. So when we connect them in series we’ll get the 4.5 to charge out mobiles and tabs etc.

Step 6

After connecting them together, we have now our circuit complete and ready to charge what we need. In case you need to be sure, your cells are working fine; you may use the multimeter to determine the charge in there.

Step 7

Now take the USB cable and separate the female USB port from the wires and cut the wire short so that it can be placed and connected to the board properly. You will find 4 wires in the USB wire; you may cut the 2 extra wires as you only need to have positive and the negative wires.

Connect the positive wires to the positive terminal of the cells and negative to the negative terminal.. stick all wires on the board to keep them tidy. You may make maximum 3 ports on this same board for charging purpose.

Wrap-up

After completing the circuit, you may wrap things up by using another piece of board cut in the same size and a few strips to spare and fix the two boards together. Glue them properly as the narrow strips at each end and the covering board can be glued and mounted on the strips. This will give you a nice and tidy charger look.

You may also make a stand with the help of the foam board to give a slightly angled positioning so that it can absorb the maximum sunlight. Now it’s ready and you can connect up to 2-3 mobile devices with the charger to charge them quickly.
