6x6 poly solar cells tabing

[a7m1]

So, i managed to connect 32 of them 8 in each column and 4 in each raws

at the end of each column i used bus wires

So i got my positive on far left and negative on far right
now what, link all 3 tab wires of the final cell that is in serial( both neg and pos cells)

And thats would give me the power right,

I got a analog multimeter and i don't really know how to use it

Will get digital mm soon, now can i use it to power for example 12v cigarette lighter phone charger???i assume most are happy of input voltage between 12-24volts i will be using 5 or 10w usb charger

What will happen if i short circuit this thing? Final terminals of course

i don't have a solar controller or battery to recharge as of yet,

thanks

Got 17.17 volts unloaded
and 16.98 loaded with motorola microusb charger tbat outputs i believe 500mah 5v and accepts inout 10.08-33 dcv

not bad after all,
I managed to run 5 meters 3528 strip and voltage dropped to 7 in roomlight only unloaded voltage was 10-11v just in room light !!!

You can expect about 17V under load (V max power), the open circuit voltage will be
roughly 25% more. Check short circuit current to see that it has some power capability;
could be a not yet visible crack. That should be enough for your battery. I finally gave
up on 6x6 cells, because I couldn't build a panel without some of them breaking. Then
I would have to wire shorts across the bad ones. Bruce Roe

Thanks bruce Roe,

I am not even sure that i'll use my panel after being built for power(it's really not worth it ) electricity here "in kuwait is so cheap thay it'snot worth to replace lead acid battery every year or so

i'll use it for led lighting in my room and charging mobiles


so what the usual range for solar controller input voltage,? Do they have (step up or down boost circuit) i am talking about cheap controllers also about expensive ones
Can i use a solar controler without battery attached?
I may use dead or weak battery as ( shock absorber) or none

Thanks again

So I got 40pcs 6x6 4.1w cells with leadbox, flux pen,
tabbing wire and bus wire and terminals.

I crqcked 6 cells in the process of tabbing.
This will hopefully ends up with 17v open circuit am I right? Will cheap charge
controllers accept this voltage to charge a 12v battery? Thanks
