aluminum panels How to Build Your Own DIY Solar Panels

At first glance,Building your own solar panels doesn't seem like a project of your own,But actually it's simpler for many other DIY projects.Solar cells are a complex part of solar panels,You can buy them cheaply.Once you have a solar cellYou basically have to weld them together.Put them in the frame.And connect them to the terminal.The good news is that you can build a solar panel for about $1 per watt, while the purchase price is $1/2 to $3 for the completed panel to run, so your savings in a 3600-watt system is equivalent to a range of $5,000 to $7,000.Buy your solar cells.Polycrystal solar cells are available to consumers from a small number of suppliers on the Internet.Probably the best source is eBay, pricing is very competitive because there are a lot of vendors,EBay has a seller rating system so you know their rating and you are working on a reputable vendor.The most common size is 80 sisters from 150 sisters or 3 1/4 "x6" with an output of 0.5 volts,3.5 amps or 1.75 watts.They are available with labels or untabbed.The tab-style version has tabs for connecting cells together and has been welded to cells, so they are easier to use.I suggest you use at least the label version of the first panel.You will also find defective cells with less money available with slight aesthetic problems and broken cells.The disappearing cells performed well,You will have a spotless panel,So they work,But broken cells will be hard to weld together and will not produce a consistent force, so I will leave their enthusiasts.Additionally,You should make sure that your goods are insured because the cells are very fragile and you don't want to pay for broken cells.Build your solar panel frame.The first consideration is that the size of your panel will be determined by the number of solar cells used per panel.Keep in mind that in your plan you want to make all panels the same size as the same electrical output.For example,Solar cells are arranged in 4x9 matrix if you use 36ea 3 "x 6"You can create a panel that will output 65 watts and measure 55 cm x 70 cm (25" x 32").The cheapest panels can be made with plywood backplates and wood frames.This will need to be coated with several layers of external primer and UV-proof paint, so it will last.If you want a lasting panel,You can use the anode alumina frame.Weld your solar cells together.Let's say you're using a label cell,Using the 4x9 matrix mentioned above,You need to do 9 cells with 4 strings.Each cell will have two labels welded to the back or negative side of the cell.These tabs will be long enough to span the back of the next cell and should be welded to each contact of the next cell.Be sure to leave 1 cm or 1/2 between cells.It's a good idea to curl the label for this gap before welding, so you have a small expansion and contraction of the swing space due to weather and imperfect measurements.Continue to weld the cells in this way until you complete your 9 cell strings.Finally,You need to weld the negative contact of the first cell of the label, so you have clues at both ends of your string.Test each string with a multimeter to make sure your connection works and you get at least 4.5 volts and 3.5 amps

Final assembly of solar panels.Place four strings on the panel to make sure they fit evenly and the cells don't touch.Make sure you rotate your string, so the front thread at the end of a string will be next to the front thread of the next string.If everything looks goodConnect each unit to the panel of the silicon caulk with the dab.Next, we have to weld the string with copper wire or label tape.Connect the positive lead to the negative lead of the next panel so that all strings are connected in series.Finally weld the 25 cm or 12 inch wire to the negative lead at one end of the panel and weld the wire to the positive lead at the other end of the panel to create the one that will be used to connect the panel together.Test again to make sure you get the output of 18 volts and 3.5 amps.After a few days, the silicon chip will dry.You should cover the cells with plexiglass or tempered glass,Seal the edges with silicon that you do.
