How to Build a Solar Battery Charger

An interesting project for solar energy enthusiasts is to learn how to build a solar battery charger. This seems like a project within a project. Almost all the solar powered devices rely on solar panels which are like the battery that stores electrical energy to run the devices later. Therefore in order to make a solar powered battery charger this would mean making a battery for or within the battery. Even though solar battery chargers are also readily available to be purchased in the market, making a homemade DIY solar powered battery charger can still prove to be more exciting and also cost effective. It also gives you a good understanding exactly how the technology works.

Therefore in order to build solar battery charger you will firstly require solar cells, while some other materials for the project include duct tape, gauge wire, multimeter, a battery holder, blocking diode, cardboard, a window frame and soldering iron. The window frame that you have would serve as the holder for all the components. Firstly, layout the solar cells on the window frame. In order to create a power source you will have to wire the solar cells together. You can wire them by soldering the cells from the back with the next cell to the front and accordingly. Make sure that the solar cells are wired in parallel so that the amps can be increased.

For this, you can just intertwine together the positive wires and also do the same for negative wires. Then connect the end of positive wire to the red lead of your AA battery holder and similarly connect the negative end to the battery’s black lead. You can then join the blocking diode to the battery’s negative lead. It is important you remember that during the process of creating a homemade DIY solar battery charger, the exterior of the solar panel should never be overlooked. This means that the solar cells should be duct-taped and should be pressed to the cardboard to get a flat panel surface.

Like the basic solar power rule you should remember to place the solar powered device in a location which is mostly exposed to direct sunlight. Also make sure to check beforehand if the rechargeable cells are functioning properly, which can be checked through the multimeter. Also, just like any other DIY project make sure to test out the newly created device frequently to find out if there is anything faulty. Checking your device frequently will help you make instant changes and learn from any errors you may have made.

You should know that the main idea behind how to build a solar battery charger relies on the type of solar cells you are using and how careful you are when assembling all the parts together on a flat cardboard surface in the window frame. Most people prefer using kitchen material for DIY projects but when making a solar battery charger it is most important that you only use commercially available solar cells and not utilize something that can be a faulty product.
