Thank you. I was just wondering why it is always 4×9 or 3×12, and now I know.

Hi Terry,

There is no fixed rules on the size or arrangement of the solar cells. 4×9 and 3×12 is the most common arrangement.

You have to take into consideration on the size of Plexiglass. If your solar panel is of non-standard dimension, it would be hard to find a standard size Plexiglass to cover it. Custom cut Plexiglass is more expensive.

You mentioned there are only two arraignments possible for the lay out of 36 solar cells. 4 rows of 9 or 3 rows of 12. My question is this why 6 rows of 6 are not possible.
Thank You
