How to Build a Solar Panel?

Do you want to get clean, renewable energy for free? Cut down on your monthly power bill? Try making your own solar panels! These cost a fraction of commercial panels and work great! Get started with Step 1 below to make your own.
Purchase the cells. There are a few different types of solar cells to buy, but the best cost-to-efficiency option will be polycrystalline cells. Buy however many you need for how much energy/wattage you’re looking to produce. The specs should be listed when you purchase the cells.
Measure and cut a board. You will need a thin board made out of a non-conductive material to attach the cells to. Lay out the cells in the arrangement you will use, then measure the dimensions and cut a board to that size.
Measure and cut all of your tabbing wire. When you look at your polycrystalline cells, you’ll see a large number of small lines going in one direction (the long distance) and two larger lines going in the other direction (the short distance). You will need to connect tabbing wire to run down the two larger lines and connect to the back of the next cell in the array. Measure the length of that larger line, double the length, and then cut two pieces for each cell.
Heat the first half of a tabbing wire on top of the soldered squares/strip to bond it to the cell. Repeat for other strips.
Glue the cells to the board. Put a small amount of glue at the back-center of the cells and then press them into place on the board. The tabbing wire should run in a single, straight line through each row. Make sure the ends of the tabbing wire are coming up between the cells and are free to move, with just the two pieces sticking up between each cell. Keep in mind that one row will have to run in the direction opposite to the one next to it, so that the tabbing wire sticks out at the end of one row and on the opposite side of the next.
Solder the cells together. Apply flux to the length of the two thick lines (contact pads) on each cell, then take the free sections of tabbing wire and solder them to the entire length of the pads. Note: The tabbing wire connected to the back of one cell should connect to the front of the next cell in every case.
Connect the first row using bus wire. At the beginning of the first row, solder tabbing wire to the front of the first cell. The tabbing wire should be about an inch longer than needed to cover the lines, and extend towards the extra gap on the board. Now, solder those two wires together with a piece of bus wire, the same size as the distance between the thick lines of the cell.
Connect the second row. Connect the end of the first row to the beginning of the second with a long piece of bus wire which extends between the two far thick wires (the one at the edge of the panel and the second being the furthest away in the next row). You will need to prepare the first cell of the second row with extra tabbing wire, as you did with the first.
Continue connecting the rows. Continue connecting the rows with the long bus wires until you reach the end, where you will connect it with a short bus wire again.
Connect your panel to a charge controller. Purchase a charge controller and connect the panel to the controller, making sure to connect the positive and negative correctly. Run the wires from the terminal block to the charge controller, using color coded wire to keep track of the charges.
Connect the charge controller to your batteries. Buy batteries which will work with the size of the panels you built. Connect the charge controller to the batteries according to the manufacturer’s instructions.
Use the batteries. Once you have the batteries connected and charged from the panel or panels, you can run your electronics off of the batteries depending on the amount of power you need for them. Enjoy your free power!
