It's not that difficult and can be done as a solar DIY project. All you need to know about how to construct an efficient 100-watt solar array at home. In order to recharge a battery of 12 volts ) car battery, rechargeable or Lipo) by using sunlight, a build solar panel that is 18 volts or more is needed. To build solar panel that is with the capacity to charge a battery 12 volts it will require.

 

Two millimeters of tabbing wire , and another five millimeters Soldering wires, tabbing wire and you need to have a flux pen. You need some good tape and a good soldering iron.

 

A multimeter that can test current and voltage. Silicone paste, especially crystal clear and with UV protective epoxy is the most effective and easiest method to make it yourself. In order to encapsulate the backside of the build solar panel. The epoxy resins offer excellent adhesion to acrylic and glass as well as plastic and other materials. It also keeps out the weather and protects the solar cells.

 

The measure here is two-to-one ratio. Also lastly, the choice of the build solar panels cells in this case is entirely up to you. It is possible to purchase pre-tab solar cells that come with tabbing wire already connected. This will cost more, but it will save your time and energy. I will try to provide information to find both types of cells.

 

Let's get started. The first step to do is measure how long the cables are between two cells. Two cells are taken and joined together. In this way, two or three millimeters is sufficient with one cell facing upwards is the negative side, and the other facing down is the positive side. take the measurement of how long the wire tab across both cells.

 

Now, you have to cut and measure the tabbing cord for all 36 cells on your build solar panel, making this process less difficult. Cut the tabbing wire into one cell at one time. After that you can begin selling while tabbing on the negative end of each cell. You will need to make the first step across each conductor line. the flux pen. This helps the solder flow and bond smoothly.

 

Place the tab wire in the cell and begin soldering in the middle the whole process beginning from bottom to top, in a continuous movement. This is not that difficult. You must be ready for a few hours of work. The polycrystalline six-by-six cells typically includes three connected buses. We need to join 36 cell on one side,, and then it is welded with solder onto the positive side.

 

The reverse of every cell produces a string of 18 volts, which is the required voltage to charge a 12- Volt battery.

 

One of the most effective and most durable materials to utilize in a build solar panel is glass that is tempered. Three millimeters is sufficient for toughness and durability. It's also the perfect location to start the process of soldering solar cells. Start by giving your solar cells a thorough cleaning.

 

Clean and dry, we can begin building things But first, we'll look at how  build solar panels work again. First, we will look at the negative end that is the solar panel's negative side. It will be joined into the wire for negative bias which came from the negative side on the solar panel. following with the subsequent three cell strings.

 

They were all joined at the back and front of the other, creating the total 36 cells with 18 voltage.

 

A second thing to consider is solar cells are fragile in this regard. It is almost certain that you will crack one of these cells even if it's only a tiny scratch, you could use tape that you already have and fix it fast. Once you have a basic understanding of how solar panels work is the necessary to link all of the cells that are needed to accomplish this task.

 

Here are some suggestions to follow in order to do this properly. It is easy to use the tweezers of your choice as well as a weight that holds your wire at the proper position to join. A good scissor, will be helpful. Another tip to consider is to use ordinary tape to keep the cells in the right position. This way, they remain aligned, which allows you to join more easily and speedily.

 

If the tabbing wire is too long you can simply cut off the ends that aren't being used when you're done.

 

It's time to wash the glass. The glass surface now that the glass is clean, it's time to place to secure and fix the cell into the proper position. The string is measured by measuring the cells that is closest in proximity to the glass's edge. We determine the margin on both sides of the panel. After all cells are set, we must to ensure that each cell in a tight connection with the glass. Start with normal tape, then following with short tape.

 

Now, the tape is passed across the top and bottom each cell. At simultaneously, it's beneficial to double-check for damaged cells even if there's just a tiny crack, since in the event that there is a crack, the encapsulation will go through it and the epoxy of the  will eventually begin to yellow.

 

Now that all cells are secure in their place, we can proceed with each cell in the cell string into the bus. Start by cutting a 5 millimeter wide tabbing wire the same width as those two strings of middle cells. Then fix the wire to the bus with regular tape.

 

Cut the loose ends off the cell tabbing. You're now ready to connect the two rows of middle row this way. Join the tab wire on the positive side that the cell is to the bus wire that will be connected to the negative end, and ,move to the next cell.

 

Then, perform the same procedure for the two other rows of cells along this panel's upper. It then ends with the two bus wires that are negative and positive poles.

 

Then, using 36 cells, connected to the negative and positive bus wire, it is time to check. If we are able to find an attractive solar panel that is that is facing the sun, test the voltage using an instrument and ensure that it generates at least 18 volts. This is what This is what I normally do to test the electric production.

 

Be aware that solar panels will have a tendency to lose tension during the most intense time of the day. Depending on the region you live in you will get around 18.6 voltages during the most intense sun times. Back to work We will proceed via cell using two copper wires that connect to both poles on the. You can also make use of the five millimeter bus cables and connect them with the junction box located in the middle bottom of the screen.

 

However, I chose the copper wires to accomplish exactly the same task however, I'm not making use of a bypass diode as I'm going to use an electric control that is charged with PWM. The solar panel and battery will be protected from overcharging and reverse current are protected from reverse current and overcharging, and vice versa.

 

Let's get started by preparing the solar panel for enclosure. The first thing we have to complete is placing the silicone along the glass's edges. This will stop residents from spreading outside of the panel.

 

Resin is among the most effective ways to shield solar cells the sun's rays from moisture. If you want to make a solar panel of this size, you'll require around 40 ounces of resin around 3-pounds or one kilogram should be sufficient. It's not cheap, however it's the best option in comparison to the Ava film that is used to protect the solar panel you make by yourself.

 

To learn where to purchase this kind of Clear epoxy resin. Check out my links on this page.

 

Also, of course, he uses a uses a epoxy-hardener in this. The mix must be twice the epoxy resin to be one that is sufficient hardness.

 

Mix the two components into a plastic container, and mix it up slowly. The main reason is to prevent air from getting in the mix.

 

After two minutes, mix the resin and the hub. Mix it with another container for a faster and more robust curing end. The second mix must be created to create the perfect, properly cured resin.

 

What we need to do is place the mixture onto the side of the. To do this , apply the epoxy from the top down, and with a steady flow.

 

After 12 hours, you'll be left with an enclosed & protected solar panel.

 

The next step is to construct the frame of your panel. Get three L-shaped aluminum profiles that are two meters long and at least 3 millimeters thick. You could also choose word, but it's all dependent on your budget and the amount you're willing to spend on your panel. This can be accomplished in the beginning. Once you know the dimensions of the glass. Then, and the frame for the panel is constructed.

 

Then the glass placed on the frame, you can seal it with Silicon. Then proceed with the welding of the cell and bus wires until the enclosure is complete However, make sure to put the silicone around the glass's edges before encapsulating. Here are some images of how to build an appropriate frame to fit your panels by in measuring the length of each glass side.

 

Note each profile using markers. At minimum 2 millimeters along the cutting edge.

 

For cutting the profiles. It is possible to utilize a cutter holder having an angle of 90 degrees however, it is recommended to employ a miter saw

 

It is possible to purchase the ruler which can be used to test the cutting edge. It's also helpful to ensure that the profiles remain in the correct position when assembling and the most effective way to join the frame and glass by using screw and stainless steel brackets. I've used 12 brackets for this build solar panels, eight brackets to support the glass , and four brackets to connect the two profiles. set the brackets up then mark the holes and drill them.

 

As I said earlier, we could make the frame prior to putting everything together. It is possible to make the frame and then attach it to the glass using silicone. We can then begin to assemble with build  solar panels cells bus wire and finally, at the end , the encapsulation. Also, you can you can add the silicone to the base of the inside of each profile. Attach the frames to each glass. Next and then put the brackets on.

 

The junction box, and then the solar panel of 100 watts.

 

Then we will build the frame, and then the encapsulated panel.

 

Now we can are ready to put in the brackets. However, if you choose to put an additional back sheet to the side of your build solar panels, take it off prior to creating the holes in the frame. Then, install the brackets in this position. I'm not making use of this backsheet. This is because it allows you to observe how the reverse on a solar panel is.

 

Connect the junction box using similar silicone glue. create a hole that allows for the pole wires and you will you'll have a build solar panels on your hands.

 

Then, watch the next segment in which we will examine the amperage and voltage.
