Well, it wouldn't be impossible to make it work, but would require a bunch of modifications.
First thing you would need to do is figure out the forward voltage of each led (it's probably 2 or 3 tiny leds in each package, making each led require 6 or 9v to work)
It looks like it starts from top right and you have 2 leds in parallel , then these 15 groups are in series and you can sort of see a traces going from the 4th group on the right, back to the 2nd column of leds from the right and so on.
So in theory, you COULD use a sharp knife or something to CUT that trace that goes from the 4th group of leds back to the top and then cut the trace that goes from bottom of middle column to the top of first. ... and you can now join the 6 columns at the top and at the bottom
See picture below ...
Your "panel" would now need at least 4 x forward voltage of one led, so at least 4 x 3 / 6/ 9v ... worst case 36v ... but the current is much higher. Let's say 100mA per led (because original design says 30w and it's 30 leds so 30 leds x 9v x 0.1A = ~ 27 watts if there's 3 diodes in each package) , you're looking at 6 columns x 100mA per led = 600 mA ... but you don't need to drive them that hard. Even at 50-60mA per led it would still be quite bright.
So you'd want to look for a led driver that can do 15-30w and let you adjust current to around 300-600 mA of current.
For example :
