  • How do you solder 6X6, three tabbed cells @ the end ?

    The cells I am using are 6X6" and have three lines on each side, that have NO solder on them what so ever.
    I understand you have to go from Top(-) to bottom(-) when soldering. BUT how do I deal with the three tabs on each end. Right now I'm only using two cells but later plan to go a LOT bigger.
    Thanks in advance

    I think that's a question best asked of the seller.

        to let you know somebody read your post and you were not being ignored.

        If the cells are missing the solder/metal mask, I don't know how they think you are supposed to connect to them.

          That part is easy. All ya have to do is flux & solder. It's the 3rd bus bar that is screwin me up !!! I cannot figure out how to connect the ends. TY for your time.

            Madtrapper you are an unreasonable person. Mike went to the trouble to basically say.,he doesnt know the answer and most likely most others on here wont know either,so to get the corrrect answer it is best to ask the person that sold them to you.
            He gave the reply that myself or cariboocoot or icarus would have given.. Its an unusual configuration.seller is best bet for knowledge of them.

              Be more specific with your goals. Do you just want to connect the cells in series? If so, the tab wires on top of the first cell goes to the back of the next cell. At the end of the string, all three tabs are soldered onto the bus bar.

                TY for yer time Axis

                I have two 6x6 cells, which have three white lines on either side(this is where ya put the flux). With the top of the cell being (-) and the bottom being (+), you solder from the top of the 1st to the bottom of the 2nd. Tab the (+)'s together and (-)'s together = power.
                What I'm trying to accomplish is a small, 2 cell panel, to run a couple of small motors(one @ a time). It's the third bus bar that's screwin me up.

                I can be a bit thick sometimes and I suffer from brain farts which makes doing things more tedious.

                  Solder the three lines on the front of one cell to the three lines on the rear of the second cell (left to left center to center and right to right.
                  Solder the three lines together on the front at one end and the rear at the other end. Voila a 2 cell module.
                  that will put out about 1 volt.

                    No voltage

                    Right now I cannot even manage to get one cell to pump out the proper Voltage (4.1v) !! I have soldered all the (+)'s together & all the (-) together (of the one cell). The cell rated @ 4.1v isn't even putting out 1/4 of a volt.
                    I'm flummoxed !!
                    Thanks

                      It is rated at 0.5 volts,around o.55 open circuit voltage. Even without tab wires, you should be able to measure the voltage. Poke tester leads directly where the tab should go(red on the bottom, black on top) You dont have to connect all the tabs to get a reading. One on top and one on bottom is enough.

                        Regardless of size, a single wafer/cell will only produce 0.5V That's why it takes 36 of them in series to have enough voltage to recharge a 12V battery.

                        Amps depend on the amount of (intensity) light shining on them.

                        What sort of spec sheet acompanied the cells ?

                          Madtrappers problem seems to start from what appears to be tha fact.NO information came with the cells.
                          Flea Bay specials?? 3rd rate,and way below spec.?

                          The usual type of cell DIYs use to make substandard ,short lived panels.

                            3 Tabbed cells

                            I can see why the third tab is baffling you but it is buss tabbed the same as single or double tabbed cells. The front of the cell is negative and the back is positive. Connect your cells to the string size you need pos to neg for each cell. To connect 2 strings to a buss tab solder all 3 tab wires of the neg to the buss then connect all 3 pos tab wires in the next string to the buss. Heres a diagram I made. See if it makes sense now. Good luck

                              Sorry madtrapper I see you only want to connect 2 cells. Tab first cell on front side for neg.and leave extra at top to connect to a buss tab. Tab the secnd cell on back pos side and leave extra tabing to connect to a bus tab . tab all three to the bus tab at neg and pos. Those are your plus and minus connections
