Solar Panel Overview
How to solder the solar cells to make a list of cable networks in a solar panel
If you are considering a DIY solar project, he are many practical details and techniques that you really have to overcome. It is really advisable to get a complete guide DIY solar how to build a solar panel without it, you wasted your time and money. If nothing else, give you a good overview and can decide If DIY is appropriate for your situation.
One aspect of a project DIY solar panel holds all the solar cells, about 36 per panel. Each cell is connected to another in a series or "chain" between tabs "son" of special coating solder in each cell, ie, they need to be connected. You may be aware, but before you start, it should be noted that there two "legs" and "no tab" solar cells on the market. tabbed cells are more expensive, but believe me, "it's worth paying more and save lot of time, the cells broken and frustration. The cells were tabbed connector strips already attached to the front side bus (on the sunny side) and enough time to accompany your next cell. Most cells were negative on the front and back positive. So basically what we do is connect the negative from one cell to the next cell positive feedback and so on so that it can form an electrical circuit.
Why using cells with tabs? Good question, quite simply, if you don t have twice the welding, the front side bus is the most sensitive fiddliest, employment frustrating and so not a good connection, that the cell can not function properly. Basically, with the cells of the UN by tabs, you need to weld the bar tabs for each cell before soldering entire chain, so - buy cells with tabs. Also be a good quality adjustable from 65 to 75Watt soldering iron, use a game to 700F.
Ay Caramba - I know, you've already purchased non-tabbed cells. Well, I'll tell you what must act quickly. There are two options, the more uncomfortable. Now, the compilation of the band typical solar consists of 10 to 15 microns copper alloy sheet welding cover, and is commonly Sn60 (60% tin and 40% lead), note that contains lead. Each band must extend through the two-cell and the gap between them. The strip can be welded directly to the cell with the flow or, before the welding of each strip and then weld the cell. If you care about the weld You can get a good adhesion between the cell bus and bar tabs. Remember that if the link is not good, no current.
Since I'm lazy, I do not want to pre-weld the tab bar. In all cases, apply to the feed bar (The large bright fringe at the front). Place the tab bar in the bar of heat flux and a flat tip of the welder, running slowly down the strip. The back of the bottom band and a preserved link to the cell. If you have a tough job just pull the tab. It's a good idea of waste, or a cell phone or using a snap to get an idea of welding the front-side bus. Now maybe you can see who is better to buy cells with tabs.
Now we all have tabbed all cells and are ready to rock and roll. We are now beginning to heat, a "chain" of cells together. Therefore lay the cells in a tabular format (eg, 3 sets of 8 cells), or whatever your design becomes. It's a good idea to draw a model on a cardboard round to make it clean and safe game, allows a small space between them.
Now here's the catch, which cover everything (sun instead of down), but the tab bar to the first of what is put on the back of another. Do the same thing at the bottom of his "chain" so that all queues are in the back of the next cell. Basically, we're going to weld the free end of the strip aggregation contact points on the back of the next cell and repeat the process until the chain. If the cells are like mine, there Small plots will be 6 goals which are contact points we welded.
Align the tab bar to open what is happening on the points of contact, then apply the stain flows. Use something to keep the tab again and place the hot soldering iron tip on the tab bar to the point of contact, touch solder wire to the tab and let it flow. Do not use too much and not overheat the cell or can be harmful. I am using the paste instead of flow welding wire and it works well. Once contact points are welded, you have the beginning of a string. Simply repeat the process for all cells of the chain.
I want to check that the connections are good, I will expose the cells to light and check with a voltmeter which is not common. At least, check each string, it is too late when you are connected at all to find there is a "dry solder" somewhere and have to overcome. Once done, you have a series of connected cells.
Now there's one thing to do. In the last cell in its chain, the "top" of clouds on the sunny side (negative side), free and unconnected. Later, the chain connected to the next by a bus connection or cable. But at the other end (beginning), no free connections. We must disclose certain tags short socket at the rear of the first cell (positive) so that we can form an electrical circuit. Thus, in the "first" cell Welding strips navigate through the contacts extend back to where they are connected, have now links the two beacons ends of the chain. With those taken in both ends of the string, you have a job "string" of cells. In fact, now that you've read this far, mostly those of welding in the first, and then continue the chain.
So now you have a complete chain ready to put in your box the panel after the test correctly. Now you can see there is some work involved in building a href = "http://www.solardiytips.com"> DIY solar panel. We mistake, DIY is fun and can save money, but there is work to do. After reading this site or get a DIY guide, you can opt for a solution off the shelf, but - still miles ahead and better informed about what is involved in a solar system. However, if you have patience, you can save a lot of money by making your own panels.

classification of firms' products?
We sell three types of solar panels. The first type is less expensive but poor quality, half second type of cost and quality is average, and the third type is the most expensive but best quality. For advertising we want to appoint classes. For the first time we call economy class. The last time I call the premium class. We need a name for the second class, but we can not think of a good. In short, we have .... $ $ $ - Premium $ $ -? $ - The economy of all the suggestions for middle name?
