DIY Solar – Soldering Solar Cells

In case you are constructing “solar panels in your home”, one of the crucial necessary issues to study is correct soldering of the solar cells. Constructing your personal solar energy system could be a very enjoyable venture, however in case you are having hassle soldering your solar cells then cease proper now! After I first began by first try and solder, I failed. I believed to my self, “what am I doing mistaken”, then I found the key to soldering solar cells. Observe the directions under for completely acceptable soldering strategies.

1. 1. Cells I exploit – To begin this mini-training collection, you want to decide what kind of solar cells to make use of. My very own personal choice is the three x 6 inch cells which can be rated at.5 volts every. I discovered that these are simpler to solder and work with.

1. 1. Soldering iron – This is likely one of the trade secrets and techniques of the professionals, a correct soldering iron. I’ve discovered experimenting with totally different soldering irons and totally different wattage of warmth the very best options is to make use of a 40 watt iron. Purchase an excellent heavy-duty iron, I recommend a soldering station with a wipe sponge to maintain your tip clean always. The tip I favor has a slight angle to it and could be simply changed. To not use any tip wider than 1/8^th inch.

1. 1. Solder to make use of – It is a essential step in soldering solar cells, the right solder. There are such a lot of totally different solders available on the market that your head will begin to spin questioning which one to make use of. My rule right here, KIS (maintain it easy). Any electronics provide will carry solder made for electronics tasks that can have a low melting level. That is essential when soldering our cells.

1. 1. Soldering flux – It can be crucial that when doing a DIY solar venture that you simply use correct flux. The aim of soldering flux is to situation the metallic that we’re attaching to, in order that the solder will draw or simply connect. Use liquid flux accessible in pens designed for electronics.

1. Warmth sink – Right here is likely one of the greatest steps to observe if you would like good solder connections. If you wish to have constant soldered connections, then I might advocate utilizing a chunk of tempered glass. After I construct all my solar cells I exploit ¼ inch tempered glass. I construct all my cells by encapsulating them on the glass, so this works nice for soldering them additionally ติดตั้งระบบโซล่าเซลล์.

Very first thing you should do is plug your soldering iron in and let it come to the right warmth temperature. Subsequent, put together your tip to be used by making use of solder to it and see if it melts simply. The primary time you utilize your iron you should clean your tip by making use of solder then pulling it via your moist sponge, this may coat your tip with a glaze of solder. Now you might be able to get began.

I begin by ensuring my glass is completely clean by utilizing some kind of glass cleaner. Now take certainly one of your cells face up or the facet that faces the solar, that is your detrimental facet when hooking them up. Having already minimize your tab wires to the right size we will begin to solder them to the cell.

Apply flux to the 2 silver strips on the solar cell. Here’s a little trick to assist make your soldering simpler. Use sockets from a socket wrench set to carry down your cell whereas making use of solder; this retains it in place whereas stopping warping of the cell. Subsequent, lay your tab wire flat towards the silver strip and maintain in place utilizing a small flat tip screw driver. Apply a small quantity of solder to your soldering iron; this will likely be all you want because the manufacturing facility tab wires are already coated with solder. Now draw your soldering tip throughout the tab wire, you’re going to get the right really feel for this because the solder melts as you progress the iron alongside the solar cell. Hold doing this till you’ve sufficient cells to do one full panel.

After soldering all of your detrimental sides of your cells you might be prepared to begin becoming a member of your cells collectively making your stringers of cells. Flip over one of many lately soldered solar cells then take one other one and slide underneath the tab wires and dab every of the 6 silver solder factors with flux, and connect the identical means utilizing solder for every of the solder factors. Guess what, you’ve correctly soldered your first solar cells!

What’s nice about this technique is that you’re already forward of most individuals who have no idea the right solution to solder solar cells. Simply bear in mind, simply the correct amount and don’t depart the warmth on to lengthy or you’ll warp your cell and probably broken it.
