Look around yourself! What do you see and feel about your surroundings? What is the one thing that comes to your mind when you look around yourself? Isn’t the word “Pollution” coming to your mind at the very first instant? Are you also thinking about the same thing we are worried about? The world has been trapped in the miasma of pollution where human beings are desperate enough to find alternatives to suffice their interests causing no pollution. The need for the replacement of non-renewable sources of energy with renewable sources of energy has been on the rise.

Amidst such situations, the best way to utilize renewable sources of energy in your everyday life is utilizing solar energy as a battery charger. The Solar battery Charger can be an excellent choice. So, We know you are here to know about it and find out the exact Solar battery charger you can buy. So, let us start!

What to Look For in a “Solar Battery Charger”

  • Efficacy of the device – If you want to choose the best Solar battery charger then consider the amount of efficiency it has. The efficient variety would impart extraordinary results. So, check the efficiency before buying the solar battery charger.
  • Resistance to Water – Resistance to water is one of the very important criteria for choosing a solar battery charger because the solar panels are the best working when you put them outside in the sun. You never know when there will be suddenly heavy downpour and your battery charger will be exposed to water. So, better be prepared and prefer the one resistant to water.
  • Output power – The output power is a very important criterion you should consider while buying a solar battery charger. It is on the power that the devices you can charge depends upon. If you are using a solar battery charger for phones, then low power is fine but if you are using it for charging car batteries or laptops, then the battery charger should impart greater output power.
  • Battery quality – The quality of the device that you are using is one of the biggest questions. If you are buying a good quality product, then it will give you service for a longer period of time, not get damaged easily, enable quicker charging, and will be flexible enough for you to use. 
  • Durability – Apart from all the points mentioned, the biggest point of consideration is durability. How durable your solar battery charger is: is a question that would arise in your mind first. So, consider this point before buying the solar battery charger.
  • Surface area present – You need to check the amount of surface area of the solar panel is exposed. If the solar panel has a large exposure, then it is highly likely that you obtain great power consumption capability. If the surface area is less, then charging of the power source will be slower. The device will be more powerful if it has a better surface area for the solar panel.
  • Type of Panel – Be assured about the type of panel that you are using as your solar panel for the solar battery charger. Check if it is semi-flexible or rigid in nature. If they are semi-flexible, then they are easily adjustable and if they are rigid, then adjustments and portability can be a little difficult. 
  • Size and Connection points- The size of the solar battery charger is a very important point to consider. It has to take up space if it’s not portable and thus it should absolutely fit into the space allotted for it. If the thing is portable, then it should not be huge otherwise there will be problems in carrying. Next, if we talk about the connection points, the Solar battery charger should have multiple ports then it will be able to support a lot of things altogether. 


We know it is really difficult for anybody to figure out the best amidst such vivid options available in the market. We understand you are confused too. First, it makes you confused to think whether they are good enough to be bought and then if you are satisfied that they are great; you are confused which one is the best one and you should buy.

What do we mean by Solar Battery Charger and how does it work?

Solar Battery Charger is a cheap and renewable power source used to charge other items like phones, car batteries, laptops, and many more. Solar Battery Charger uses Solar power to get charged itself to later charge other things. It converts solar energy into electrical energy. It has a working principle similar to photovoltaic cells. The devices usually come with solar panels. The sunlight is absorbed by the solar cells and an electric field is created. The battery actually then stores this electricity. There remains an inverter for converting Direct Current to Alternate Current and the electricity is actually utilized next by the devices.

Why use a Solar Battery Charger?

There are multiple reasons you can use a Solar battery charger and the biggest reason is that it utilizes Solar energy which is available and is a renewable source of energy. Battery Charging is a very important facility required almost by each and every person. There are multiple devices that can easily work with the Solar battery charger like:

  • Mobile phones that are used at least once or twice daily.
  • Laptops though they may take time to fully charge.
  • Vehicles and RV batteries though it may take time to charge fully.
  • Small devices can be used like: flashlights, personal fans, reading lights,s, etc.

There are thus a plethora of reasons for which we should prefer using Solar Battery Charger and so we are here utilizing the same.

Are they worth it over other conventional options?

Do you still have doubts? Let me assure you. Absolutely yes. The Solar battery chargers are absolutely worth the conventional options. They are not only efficient but also durable. They have a longer life and utilize renewable sources of energy. 

Should you just DIY a Solar Battery Charger?

If you really love DIY products and try your hands on your skills, then definitely opt for making a DIY Solar Battery Charger. Just be sure about the major components to be utilized, the correct procedure, and the type of batteries used. Also, make the connections proper so that there is no short circuit. If you want to DIY, then your cost will also be very less. The major components that you would require to DIY Solar Battery Charger are: 

  • The solar cell of 5 volts.
  • PCB (General purpose)
  • 1N4007 Diode
  • Copper Wires
  • Terminal Blocks (2 units)
  • Battery 18650
  • Battery holder for the same
  • Battery Protection board (TP4056)
  • Power Booster of 5V
  • Wires for Connecting
  • General Soldering equipment

Let us check the steps to DIY Solar Battery Charger:

  • First, we have to be clear about the hardware requirements and collect all the items as mentioned above.
  • We have to understand the working cycle of the TP4056 properly. 
  • You need to have a switch along with the hardware to make up the DIY solar battery charger.
  • Then make the connections. First, take the solar panels and it has two wires coming out: one red which is positive, and the other black or brown which is negative.
  • Now we have to take the TP4056 Lithium-ion battery charger module and the module has two connections: IN+ and IN-. Connect the anode of the 1N4007 diode to the red or positive wire of the solar panel.
  • Now make a connection between the cathode of the diode and the IN+ and then connect the black or the negative wire of the solar panel with the IN-. Thus, the input section is done.
  • Now for output, there are 4 connections in TP4056: B+, B-, OUT- and OUT+. Take two of the 18650 batteries along with the holders and connect all the parallel (all positive common and all negatives common).
  • Now connect the common positives to B+ and solder the wires well to the charger board. Do the same with the common negatives and connect them with B-.
  • Now connect the output of TP4056 to the Booster Converter Module of 5V. There are two input terminals in the step converter module namely IN+ and IN-. Connect IN+ with OUT+ of the TP4056 and similarly connect IN- with OUT-. 
  • We can actually use a switch in between the booster and the TP4056 to facilitate ON and OFF. Glue it all together and now your DIY Solar Battery Charger is ready. 

Make proper connections and DIY your first-ever solar battery charger. All the best!
