Need some help with hookin up my solar setup
Hi i hope someone can help me with this im not totally new to electronics but some things still kind of not sure about, that being said i bought three 4.5V/90mA (mine avg 3.2V in direct sun) solar cells and a http://www.bgmicro.com/SS1203A.aspx and i know how to hook it, up but what im wondering is if i bought 3 more of the 4.5V/90mA cells could i hook 2 sets of 3 cells kind of of like this
--[ + - ]--[ + - ]--[ + - ]--
--[ + - ]--[ + - ]--[ + - ]--
and tie each set together and hook them in the controller am i right in thinking that the volts would not’t go up but the amps would, and also if anyone could give me an example on the math how i would figure out the mA of the cells all hooked up this way if it would work. the math parts the biggest prob i have with all the electronics ( should have paid more attention in school lol )
Thank you in advance for any help

You're connecting sets of three in series to give 3.2V
Adding another set of three in parallel, as you suggest, will double the current. Add another set in parallel, and you triple the original current, etc.

Ok so if im understanding it right doing it like this would make it stay at 12V but ups the mA right.
I included a picture of how i was meaning to hook them up if it helps
thank you for the help
