Homemade Solar Cell: Learn Efficient Ways To Cut Down On Your Home Energy Bill

Homemade Solar Cell: Learn Efficient Ways To Cut Down On Your Home Energy Bill

A homemade solar cell is one of the most efficient ways to power your home using renewable energy. A solar cell converts energy from the sun into electricity and is normally installed on a person’s roof of their home. You are able to purchase these new from different stores, but the problem is that they are very costly. You might spend upwards of ,000. It’s a great way in knowing how to generate electricity for free. A better way is to build your own homemade solar cell. Here is how:

Materials You Need

• Copper Sheeting•Clear Plexiglass/Perpex/Acrylic Sheeting • Some Thin Wood Strip • copper Wire • Duct Tape • Metal Guillotine • Bandsaw • Electric Ring Hob These materials focus on the most cost efficient technologies in terms of cost per generated power.

How A Homemade Solar Cell Works

1.) Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon.

2.) Electrons (negatively charged) are knocked loose from their atoms, allowing them to flow through the material to produce electricity. Due to the special composition of solar cells, the electrons are only allowed to move in a single direction. The complementary positive charges that are also created (like bubbles) are called holes and flow in the direction opposite of the electrons in a silicon solar panel.

3.) An array of solar cells converts solar energy into a usable amount of direct current (DC) electricity. To find out more information about the steps going into building a homemade solar cell, visit building a homemade solar cell.

How To Prepare A Solar Cell

For preparing the solar panel, the solar cells are arranged in rows. These must be connected for a smooth flow of energy. A sheet of plastic or glass is placed on the panel of cells so that they are protected. After this, the edges of the solar panel are framed.

How To Build Homemade Solar Panels In 6 Beginner-Friendly Steps!

Do you want to discover the proper ways on how to build homemade solar panels?

Alright now, without further ado, here are the steps involved as well as the materials required to build your own solar panel.

Materials:

Plywood panel
Solar cells
Solder
Screws
Copper wires
Silicone sealant
UV protector.
Additional wood for panel border
Plexiglass sheet
Blocking diodes

Step 1.

Cut the plywood based on the amount of solar cells you have at your disposal. For 100 watts of power, you need about 80 cells. Next paint the plywood with 3 coats of UV protector

Step 2.

Place all solar cells face down on the floor. Note that there’s a small tab at the back of each cell. Using a flux pen, apply a little of bit solder onto the tab of each solar cell.

Step 3.

Take the copper wire and put it on the soldered tab. Once it cools down, the wire will get stuck to it. Now there are two lines of wire at the back of each cell. Join all the cells together – positive goes with positive and the negative goes with the negative end.

Step 4.

Now, take out plywood panel and place all the joined cells on it. The silicone sealant will keep all the cells glued to the panel. It’s unnecessary to cover the wires at this point. Just ensure the cells are firmly stuck to the plywood. Otherwise, you might end up with a defective homemade solar panel!

Step 5.

Notice the 2 wire ends? Drill 2 holes so you can put the wire ends out through the back of the panel. Right in front of the panel, place the additional wood. This is done in order create a border around the cells. Use your screws and apply the sealant to make them stick.

Step 6.

Finally get the glass sheet and fix it to the border to fully cover those solar cells.

And you’re done, bravo!

Believe me it’s not difficult to learn how to build homemade solar panels especially if you have detailed instructional materials like DIY videos!

Homemade Solar Cell – How You Can Create Cheap Energy

Homemade Solar Cell – How You Can Create Cheap Energy

These days, everyone is talking about green energy, and many people are trying to find ways to reduce electricity costs and help our planet at the same time.

To that end, homemade solar panels are becoming very popular, as they create affordable, clean energy for residences.

It’s not only possible to lower energy costs with solar panels, but you can also earn money from the excess energy produced by your panels.

If you want to make your own homemade solar panels, you must also construct some homemade solar cells.

So, how do you go about making your very own solar cell? Well, first, there are some items that you will need:

Copper sheeting
Copper wire
Thin wood strips
Duct tape
Clear plastic sheeting (Plexiglass, Perspex or Acrylic)
An electric hob ring
Salt water
Emery cloth/Sand paper
A metal guillotine (not essential)
A bandsaw
If you are able to get hold of a metal guillotine, use it to cut a 6 to 8 inch square from the copper sheeting. A guillotine is the easiest method of doing this, but tin snips will work adequately, too.
Next, wash and dry your hands thoroughly. It is crucial that there is no grease on your hands or on the copper sheet. So, take a cloth and remove and dirt, debris or grease from the copper. Then, take a piece of emery and rub the copper down on both sides. When you have finished, the layer of oxidized copper should be gone, leaving you with bright red copper underneath.
Once this is completed, you will need to expose the copper to a heat treatment to form an oxide coating. I know what you’re thinking, but it’s not as stupid as it sounds, because the layer you will add is different from the one you have removed. The oxide layer that you will now be placing on the copper is a cuprous oxide. So, place the copper over the highest temperature of your burner. In time, a black crust will begin to form on the copper. Once one side has been treated, leave the copper to cool. If you have nitric acid, this can be used to remove the black layer of oxide. If not, tap the copper plate on a hard surface to remove the loose debris then rub it with your fingers.
Now, you will need to construct a spacer with your pieces of thin wood. Use the duct tape to fasten the wood together, as nails could effect the components of the cell.
Take a piece of Perspex and stick your electrode wire (copper wire) to it. It is best to use a thick wire and you may want to place it in a zigzag form, as this allows you to see what’s going on. However, you want to block as little sunlight as possible.
Place duct tape on one side of the copper plate and fasten the Perspex front module to the plate. Obviously, the bright red oxidized side of the copper should face the Perspex. Then, seal the whole cell with duct tape to prevent leakage, but leave a small opening to add water.
Finally, add salt water to the space between the Perspex and the copper and seal the cell completely.

Then, all you need to do is to connect your homemade solar cell to a multimeter and let the sun do its thing.

The 6 Step Basic Blueprint For Novices To Make Homemade Solar Panel!

Are you ready to make homemade solar panel?

One thing you need to remember is that building homemade solar panel is quite simple and doesn’t require extensive technical know-how.

Okay, here’s a basic 6 step blueprint to make homemade solar panel which I learned from viewing step-by-step video tutorials downloaded to my computer hard drive.

Head over to your nearest hardware store and acquire the following items:

1)    Blocking diodes
2)    Copper wires
3)    One sheet of Plexiglass
4)    Plywood Panel
5)    Silicone Sealant
6)    Solar cells
7)    Solder and soldering pen
8)    Stainless steel screws
9)    UV coating paint
10)     Wood to form panel border

My total cost: $206

1) Cut up the plywood according to the amount of solar cells you have in possession. To generate say 100 watts of power, you’ll need about 80 solar cells. Build and combine multiple panels if you require more power.

2) Paint the plywood panel with UV coating paint. Once done, you can start joining the solar cells together. Place all the cells on the ground and using the soldering pen, drop very little amount of solder onto the small tabs found at the back of each solar cell.

3) The solder applied on the tabs allows you to link all the cells together with the copper wire. The top of the soldered tab is where you put the wire and to make it stick, just press it down until the solder cools off. .

4) Now what do you see across the back of the solar cells? Two lines of copper wire! The setup goes like this: The negative end of the wire goes to the negative slot and positive enters the positive slot.

5)  Time to link up the cells! Arrange the wiring in such way that the negative wires are unable to come into touch with the positive wires.

6) Drill 2 holes to get the wire out of the back of the plywood panel, add the wood to form a border around the cells, screw from the back and finally with the silicone sealant in hand put the Plexiglass sheet on top of the panel.

Keep in mind that, if you watch step-by-step video tutorials like I have, then it will be a whole lot easier to make homemade solar panel!
