How to connect solar cell in parallel

[dausvilla77]

I bought 2 unit of Solar Cell 12V 250mA (3W). I want to connect them in parallel to make the output power is 6W.

1. Based on the picture, please anyone explain to me which one terminal I need to connect to make them in parallel?
2. In this solar cell, there is some covered plastic on the terminal. Is it ok if i remove it by nail ?


Thanks for the help.

Looking at the picture, I notice there is '+' and '-' mark at the center pads which are at point 3, 4, 9 and 10.

So basically, to connect parallel, the '+' should be connected together, same goes to '-'.

Connect point 3 and 9 together and that is '+' of the solar panel. Connect point 4 and 10 together and that is '-' of solar panel.
