How To Make a Solar Phone Charger In Your Home

Learn how to create your solar phone charger at home and stay connected wherever you go. Our step-by-step guide provides easy instructions and materials to harness the sun's power and keep your devices powered up.

Solar Phone Charger

A solar phone charger is a portable device that harnesses solar energy to charge smartphones and other electronic devices. It typically consists of a solar panel, a charging circuit, and a USB output.

The solar panel collects sunlight and converts it into electrical energy, stored in an integrated battery or directly transferred to the connected device.

Solar phone chargers offer several advantages, such as environmental sustainability, as they rely on renewable energy sources and reduce reliance on traditional electricity. They are ideal for outdoor activities, camping trips, or emergencies where access to a power source may be limited.

How To Make a Solar Phone ChargerSolar phone chargers come in various sizes and power capacities, allowing users to select a model that suits their charging needs.

Some chargers feature built-in USB ports and multiple charging options, making them compatible with various devices.

Gadgets have crept so much into our daily lives that we cannot simply think of a day without them. What do gadgets do?

They make our life easy. For example, washing machine makes washing clothes easier, Air conditioner helps to beat the summer heat, and mobile phones and tablets helps to increase communication.

Unlike most gadgets that require instant electricity to run, cell phones and tablets require electricity stored in the form of charge in a battery.

Currently, in these times, smartphones have developed so much that the battery drains out fast, and you need to charge it often. This “often charging of a smartphone” is a major problem nowadays.

Now with every problem comes a solution. Portable and solar chargers were manufactured to prevent our phone batteries from dying out in a time of need. Portable chargers have to be charged beforehand to provide charge on the go.

On the other hand, solar chargers do not need to be charged and can be just put under sunlight to charge your gadget. You can buy a solar charger from the market or make one on your own. It’s easy.

Question: How to make a solar charger?

Answer: The things you need:

  • Pure silicon panels. These generally come in 0.5 V or 1.5 V each.
  • Cardboard.
  • Cutter or knife.
  • USB extension cables.
  • Glue.
  • Ruler.
  • Voltmeter.
  • Phone Charging USB cable.
  • Lastly, your phone.

Method To Make A Solar Charger

Take a cardboard sheet and cut out a rectangular piece from it with the help of the ruler and a cutter (the length and breadth of the cut-out depend on the size of the solar panels and how many you want to put on it).

Now take the number of solar panels you want. For example, we are here taking nine solar panels. Place one solar panel on the cardboard cut-out and then make two small holes on the cardboard exactly where the solar panel wires are sticking out.

Repeat this process by placing the solar panel‘s side by side and then again in the next row until all nine solar panels are placed, and the holes are made on the cardboard cut-out.

The most important part is arranging the wire of the solar panels with each other because one of the wires is negative and the other is positive. Hence to do that, remember the following:

  • The positive wire will always have a red plastic covering, no matter what solar panel it is.
  • Suppose you place a solar panel on the cardboard with the positive (red) wire on the left, i.e., you have started from positive, which means that your other wire on every solar panel is negative.
  • Now you need to connect the negative wire to the positive wire of the adjacent solar panel. It is because charges repel each other. For example, if you connect a positive wire to a positive one or a negative one with a negative one, they will repel each other, and hence the current will not flow through them.
  • Therefore, place the solar panels by the above-stated method so that the wires’ junction is opposite to each other.
  • Once you have arranged them perfectly, put the wires through the holes you made earlier on the cardboard cut-out.
  • With the help of a glue stick, cut out the solar panels on the cardboard so they won’t fall off it.
  • After that, flip the cardboard cut-out and join the naked end of the wires to each other, as mentioned previously.
  • Having the wires joined, there will be two free wires (one at first and one at last).
  • Take a voltmeter and check out which free wires are positive and negative.

After having done that, take the USB extension cable and cut it from the middle. With the help of a knife/ cutter, cut the plastic covering of the USB extension cable.

You will be able to see four wires in total. i.e., one red, one black, one green, one white. Out of these four wires, the red is the positive one, and the black is the negative one. The rest of the wires are for earthing. Hence you can cut them off.

Join and stick the positive wire of the USB extension cable with the positive end of the free solar panel and the negative to its negative counterpart with the help of glue.

Stick the USB extension with the cardboard cut-out. Adding one or more USB extensions to the solar panel will bring down the amperage, and your devices will charge slowly.

Now cut out another piece of rectangular cardboard of the same size. After that, cut out thin strips of the same length and breadth. With the help of glue, stick the thin strips to the newly cut-out cardboard. Then place the solar panel cardboard on that and stick it with glue.

To make the solar panel stand at an angle towards the sun, make a cardboard stand and stick it with glue on the solar panel.

The last thing you must do is place the solar panel in the sun for some time and then connect your USB cable to the panel and the other end to your phone. You will now see that the phone has started charging.

This is how you will make a solar charger for yourself. If you wish to make a charger with 1.5-volt solar panels, you must connect the panels in a parallel circuit to get the same voltage, but the amperage will increase.

This will make your phone charge faster. If you had connected them in series, the voltage would have increased, but the amperage would have been the same.

Overall, solar phone chargers provide a convenient and eco-friendly solution for keeping our smartphones powered up while on the go.
