But, for those who went and purchased untabbed cells to spend less, let's explain exactly what has to be done. Firstly, you will need to solder a tabbing strip towards the "sunny-face" of each and every of the cells. There are two main techniques to try this, both fiddly. You can solder the strip right to the cell with flux or, tin or pre-solder" each strip after which solder it towards the cell. The concept is to find a connection that is solid the solar cell or it won't transfer present. Solar tabbing ribbon typically contains 10-15 micrometers of solder alloy, commonly SN60 (60% tin and 40% lead) covered on copper strip, note this contains lead. I might go without pre-soldering the tabbing strip when I'm a bit lazy. In any event, use flux towards the the big shiny strips(the coach bars) on the leading "sunny-face" associated with the mobile. Lay the tabbing strip over the bus that is fluxed along with a flat tipped soldering iron, operate slowly down the strip. Extra fingers are good here. If you did a negative job, the tab strip will peal directly off. If done carefully, the tabbing strip will connect to your coach club. I suggest practicing on a cell that is broken some extra strip to acquire a feel for the soldering. Since you can find often two of these on each cell that is solar there's a lot of fiddly soldering doing. Now do you understand why it is better to buy tabbed cells?

Now to the next step, connecting your tabbed mobile to its mate, the next mobile. Basically you will be soldering the free end associated with the top "sunny-face" tabbing strip to your bottom of the next cellular and repeating the process down your sequence. So, in the event that you failed to lay your cells out according to your panel design, (e.g. 3 strings of 8 cells), or whatever your design will be, do this now. Keep a space that is small of 1centimeter between each of them. It is a good idea to draw a template on some cardboard or Masonite to keep the strings neat and match the size of your array box.

With copper it's important not to ever miss a step or there could be disastrous results. Keep in mind these actions and you'll be on the way up to a perfect solder joint every time.

Here are the 5 steps you will need to take to get yourself a Solder that is perfect Joint time.

Cut the pipeline to size
Clean & debur the pipe
Clean the within of the suitable
flux the exterior regarding the pipe therefore the inside the fitting
Time 2 solder

Cut the pipe to size: assess the period of pipeline you shall need to join your piping system together. Using a tubing cutter, cut your pipe to size (remember to measure twice and cut once).

Clean the pipe: With some sand fabric or paper, sand each end for the pipeline until shiny. Verify the manufactures natural oils are off the pipeline. Rub by having a cloth to remove any sand or copper residue.

The deburring device regarding the end for the cutter that is tubing helps in eliminating the rough edges which may cause leakages down the road. Making use of your pipe reamer regarding the cutter that is tubing ream the inside edges associated with copper tubing removing any burr's. You want a smooth edge.

Clean your fixtures employing a tubing brush properly sized for your pipeline. To speed the method along I cut the cleansing brush near the top of the handle and insert inside of my drill.

Turn your drill rate on high and clean the inside hub for the fitting. Until it has been removed if you see any dark spots inside of the fitting keep cleaning the area.

Inactive Module

You should publish modules to the "inactive" position and set the Menus to "All", for them to show up on pages where there is no active menu ID. This is a bug/feature of Joomla that causes only menu items in the "All" setting to show up.
