Now that the tops are tabbed, flip them over (sunny part down), but, slip out the tabbing strip from the first one therefore it lays on the straight back for the next. Do the same all the way down your "string". You'll be soldering the strip towards the contact points in the relative back of the cells. In case your cells are like mine, you will have 6 small whitish contact squares. Make sure your tab strips line up so they really will sit throughout the contact spots then use flux to your spots. Hold your soldering iron to the strip on the spot when its hot, touch the solder wire towards the point and allow solder movement, do not use an excessive amount of plus don't over temperature the contact as you may harm the mobile. An alternate is by using a solder paste on the contact, lay the tab on and keep the iron on the point till it flows, for me, it was a better solution. Perform some same for all six contact points, now have two cells linked. Continue doing this procedure for all the solar panels along the string.

It's a pretty idea that is good be sure you've got good solder connections, by exposing the cells to light and testing the production voltage. At the minimum, check each string, it's too late when you yourself have connected them all up to find there is a solder that is"dry somewhere and also have to trace it right back. All soldered together, there is one more thing to do with the string of cells. The last one, with its "top tabs" free at this stage you will have at one end of the string. But at the start of the string, nothing to hook up to. So that you need certainly to solder a brief period of tabbing strip towards the straight back associated with "top" (first) cellular to have one thing to connect to and complete a circuit. So, in the "first" cell, solder tabbing strips across the trunk connections with an adequate amount of a free end to allow you one thing in order to connect to. Now you are going to have connecting tabs at both ends of your sequence willing to connect with its neighboring sequence or perhaps a connector coach. Really, now which you have read this far, its a great idea to complete solder this "first" set of back tabs before soldering up a sequence, it saves some double control.

Now that the tops are tabbed, flip all of them over (sunny part down), but, slip out of the tabbing strip from the first one therefore it lays over the straight back for the next. Do the same most of the real way down your "string". You will be soldering the strip to the contact points on the relative straight back of the cells. When your cells are like mine, you will see 6 small whitish contact squares. Ensure that your tab strips fall into line so they really will sit within the contact spots then use flux to your spots. Hold your soldering iron to the strip at that moment when its hot, touch the solder cable to your true point and allow the solder flow, don't apply way too much and do not over temperature the contact because you can damage the mobile. An alternative solution is to utilize a solder paste in the contact, lay the tab on and contain the iron in the point till it flows, for me, this is an improved solution. Do the same for many six contact points, will have two cells linked. Continue doing this procedure for the solar cells along the sequence.

This is a pretty good clear idea to be sure you have got good solder connections, by exposing the cells to light and testing the production voltage. At least, check each string, its far too late when you have connected them all up to find you've got a "dry solder" someplace and now have to locate it straight back. All soldered together, there is one more thing to do with the string of cells. At this stage you should have at one end of this sequence, the past one, using its "top tabs" free. But at the start of the sequence, nothing to hook up to. Which means you need to solder a short duration of tabbing strip to your straight back associated with the "top" (first) cell to own one thing to get in touch to and complete a circuit. Therefore, regarding the "first" cell, solder tabbing strips across the trunk contacts with enough of a end that is free allow you something in order to connect to. Now you certainly will have connecting tabs at both ends of your sequence ready to connect to its string that is neighboring or connector coach. Actually, now it saves some double handling that you have read this far, its a good idea to do solder this "first" set of back tabs before soldering up a string.
