Solar energy is a type of renewable source of energy that not only benefits humans but also benefits our environment. If you put some efforts into making a homemade solar panel, you can help prevent environmental pollution by reducing fossil fuel usage. Also, if you will use solar panels at home then you can save money on your electric bill. Building a solar panel is not difficult, to build your own solar panel at home, you’ll need to assemble the pieces, connect the cells, build a panel box, wire the panels, seal the box, and then finally mount your completed solar panel. To make a DIY solar panel at home follow the steps given below:

Assemble the Pieces

There are different types of solar cells to buy, and most of the good options are either made in the United States, China, or Japan. Nevertheless, the best cost-to-efficiency option is most likely polycrystalline cells. The quantity of cells you should buy totally depends on the amount of energy you want to produce. The specifications should be listed when you purchase the cells. These cells can be easily bought online through websites like eBay, but you may get some from your local hardware store. It is necessary to clean wax off of the cells if the manufacturer delivers them in wax. dip them in hot, but not boiling water to remove wax.

Measure and cut a backing board.

For this you will need a thin board made of a non-conductive material, such as glass, plastic, or wood, to attach the cells. But first lay out the cells in the arrangement you will use, then measure the dimensions to cut a board to the measured size.

Also, leave an extra inch at both ends of the board. This will be used for the wires that connect the rows together. Wood is said to be a more common backing material to choose because it’s easier to drill through. You’ll also need to drill holes in it for the cell wires to pass through.

Measure the tabbing wire and cut

Now, when you look at your polycrystalline cells, you’ll notice a large number of small lines going in one direction (the long distance) and two other larger lines going in the other direction (the short distance). You just need to connect the tabbing wire to run down the two larger lines and connect to the back of the next cell in the array. First, Measure the length of that larger line, double the length, and then cut two pieces for each cell.

Flux the work area.

Use a flux pen and run 2-3 lines of flux down the length of each cell strip, or group of three squares. Just make sure to do this on the back of the cells. This will help to keep the heat of the soldering from causing oxidation.

Solder the tabbing.

With the help of a soldering iron melt a thin coat of solder onto the back of the cell strips. Though, this step is not necessary if you purchase pre-soldered tabbing, which is indeed a better option because it cuts time in half, heats up the cells only once, and wastes less solder, but its more expensive.

Bond the wire to the cells

Lastly, Heat the first half of a piece of tabbing wire with a soldering iron. Now, bond the wire’s end to a cell. You have to repeat this bonding process for each cell.
