Do you want to cut down on the energy bill every month? It is time for the fresh and free alternative energy sources such as solar, wind and ocean. In this post I will go over building solar energy system because it is simpler and easier than other sources.
If you are interested in electronic work, here we have the best multimeter for electronics.
Step 1: Gather all the needed pieces:
1. Polycrystalline cells
The most important stuff is the cells. You can see many different types of cells on the market, but the best quality cells are made from polycrystalline. You can buy them on the Internet easily, or in some local hardware shops. These cells can be cracked easily, so be careful, once they are broken, it is hopeless to fix. You should buy extra cells.
When you make a deal with suppliers to buy poly-crystalline cells, they often cover a wax layer around the cells in order to protect them during the delivery. To remove this wax layer will take you more time, so you should order poly-crystalline cells without being dipped into wax. In case you receive these cells added a wax layer, remove the wax by dipping the cells in the hot water (not boiling water).
2. A non- conductive board to attach the poly-crystalline cells:
Get a thin non- conductive board, lay it down on and arrange the cells as you decide. Next, measure the board to cut it, remember to leave about 2 inches on both sides of the board in order to save the space for wires, on the space, make holes so the wires can come through.
3. Prepare the wires:
Look at the cells; you can see there are 2 large lines going down to the front. You job is connecting the wires running down that two lines and linking with the back of the next cell. Next, measure to cut the wires. The length of the wires is double longer than the length of the 2 large lines. You need to prepare 2 pieces of wire for each cell.
Next, you bond the tabbing wire to the cells; repeat this to other strips till you have a string.
Step 2: Build a panel box:
The panel box material should be stiff and easy to work with, wood box is a recommend. You can use marine plywood and weather- treated strip, they are perfect ideas and you can find them on everywhere.
- Measure the board that attached the cells and makes sure the panel box fits it. Next, cut the plywood following the size you have measured; remember to add the space for the sides of the box, using a jigsaw or a table saw, it is up to what you have.
- Next is completing the box with the sides. Measure and cut the pieces, then secure them on the bottom of the box together using butt joints and deck screw. Make sure to screw through the sides, into the base. The ideal number of screws for each side you should use is 3, but it depends on the side’s length.
- Now is the step that I think you like the most: Painting your favorite color on the box. I have one trick for you: if you paint the reflective color such as yellow, white… your box will be kept cooler and then the cells can work better. Remember to use outdoor paint which can prevent the wood and help your solar panel last longer.
- In order to keep your box away from the warpage, you should cover the box with some water- resistance marine paint layers.
- Next, attach the panel box with the cell board to complete the solar panel, using glue and make sure they are all secured. Remember to let the side that contains cells face up to the sun so they can collect the sunlight.
Step 3: Connect the panel to the batteries:
You have the box, now get the diode and connect it to the bus wire from the panel. Next, your panel should be connected to a charge controller, and then connect the charge controller to the batteries following the instructions, make sure the batteries are suitable with your panel size.
When you are done connecting process, you can now run the electronics and enjoy the free power.
Step 4: Decide the place to mount your solar panel:
There are many ways to mount the panel depending on your using.
The most common way is to mount it on the roof. However, it can limit the time to get full exposure. You should choose this option if you have many panels without a large space to place.
Solar energy is safe, free and helps you save a lot of money. So it is a wise decision to build a solar panel. Follow my steps and good luck!
