DIY 100W Solar Panel: How to Make Homemade Solar Panels from Scratch


Do It Yourself 100W Photovoltaic Panel: Exactly How to Make Homemade Solar Panels from square one

How to make a homemade solar panel? This is the first in three videos of a solar DIY project. Everything you should know to build a 100 watt solar panel at home in order to charge a 12-volt battery with solar energy.

A solar panel with 18 volts is required so to build a solar panel capable of charging a 12-volt battery. You will need 2 millimeters of tabbing wire and another of 5 millimeters solder wire is a must: have a flux, pen, strapping tape, also known as short tape.

Regular tape, a solder arm between 60 and 80 watts and multimeter, one that conveyor of both voltage and current silicon paste, preferably crystalline with UV protection, epoxy resin, the best and easie way to do it yourself to encapsulate the back of a solar panel.

This epoxy resins have excellent adhesion to glass and acrylic plastic and ethoxy hardener. Here the measure is two to one ratio and, of course, last but not least, the solar cells here is up to you. You can purchase preet absolu cells, they have tabbing wire already attached.

It will cost a bit more, but will saves you a lot of time and work in video description below you find links to everything you need to start building your solar panel. Let’s get started. The first set we have to take is to measure the length of the tabbing wire between two cells, grab, two cells and join them close to each other, like this, two or three millimeters between them is enough.

With one cell face up is the negative side and face down: is the positive side measure the length of the tab wire along both cells? The job here now is to measure and cut the tabbing wire for all 36 cells for your solar panel to make this task less tedious cut the tabbing wire to one row of nine cells.

At a time, and after that, you can start cell during the tabbing wire on the negative side of each cell to do this first pass along each conduct line the flux pen. This will prevent beading of the solder Arum and also helps the cell to flow cleanly position.

The tab wire on the cell and start soldiering from top to bottom in a continuous movement soldiering is not so hard. You get it right very fast, but get prepared for a couple hours of work, so this type of 6×6 polycrystalline cells usually has three connecting bus lines.

We have to weld 36 cells on the negative side first, where next it must be welded on the positive side that is the back of each cell, creating a string of 18 volts, the needed current to charge a 12 volt battery, one of the best and strongest Materials to use in a solar panel is tempered glass.

Three millimeters are more than enough for strength and durability, being also the ideal surface to start cell during your solar cells start by giving a good cleaning. Now, with a clean surface, we can start put things together, but first let’s again see how a solar panel works.

The first cell in this row is the negative side of the solar panel that will be welded to the negative bass wire becaming. This way, the negative pole of the solar panel and continuing with the next three strings of cells, all welded together from front to back of each other, making this way a total of 36 cells of 18 volts.

Another thing to note is that solar cells are very fragile for this reason and almost guarantee you will break one or more cells, even if it is a very small crack, you can use regular tape and repair it easily.

Now that you know how a solar panel works, it’s time to connect all cells together. To make this task much easier. Here are some tips you can use to do this correctly. It is convenient to use a type off tweezers or even a way to hold the wire in the correct place to weld Here.

I am using a scissor which works very well. Another useful tip is to use normal tape to hold the cells in place. In this way, they remain aligned, helping you to weld more easily and quickly, and if the tabing wire is a bit long, simply cut off the loose ends.

When you finish the job now with all cells tab together, it’s time to clean again the glass surface. Now, with the glass clean it’s time to position and secure the cells in place by measuring the string of cells closest to the edge of the glass.

We find the margin on all sides of the panel, then, with all cells in place. We need to keep each string of cells tightly attached to the glass first with normal tape and next, with short tape, now pass the short eight from top to bottom, between each string of cells and at the same time, it is convenient to double check for any Broken cells, even if there is a slight crack, the cause affair is the encapsulation will pass through it, and the epoxy resin will eventually yellow over time now, with all cells secure in place.

Let’s proceed by cell during the string of cells into the bus wire start by cutting a five millimeter wide tabbing wire to the width size of the two middle cell strings and secure the bus wire with regular tape, cut the loose ends of The cell tabbing wire and you’re, ready to solder the two middle rows together here I will weld the tab wire from the positive side of the cell to the bass wire, which will then weld to the negative side of next string of cells.

Easic, as you will see, right away now, is to do the same for the other two row of cells on the top of the panel, and then it ends with this two bus wires, which show the positive and the negative poles.

And after this, with a string of 36 cells connected to the positive and negative bass wire, we have to test. If we have a promising solar panel with the panel facing the Sun measure, the voltage with a multimeter and make sure that it produces at least more than 18 volts here, I tested on a spring morning keep in mind that solar panels always lose tension in the Hottest hours depending your region, you should get about 18 point six volts.

During the peak Sun hours now back to the office, we going to proceed by soldering two copper wires to the poles of the panel. Here you can choose to use the 5 millimeter bass wire. 2 also to be connected to the junction box in the bottom middle of the panel.

Did I choose a pair of copper wires does the same job and I am not using a bypass diode, because I will use a PWM charge controller which protects the solar panel and the battery from reverse current and overcharging respectfully, among other useful features.

Watch the next video, where we continue with this extraordinaire solar panel, see you there, you how to make a homemade solar panel. This is the first in three videos of a solar DIY project.

Everything you should know to build a 100 watt solar panel at home in order to charge a 12-volt battery with solar energy. A solar panel with 18 volts is required. So to build a solar panel capable of charging a 12-volt battery.
