Hi,
Sorry I don't know much about solar cells and all, but I was wondering how come the smaller solar cell SKU#PType-Solar-Small generated upto 100mA, while the larger one SKU#: PType-Solar-Large which is 4 times as large only generates a max of 280mA.
Is because how they are wired internally? Serial/Parallel?

Thanks.

The smaller cell only outputs 4.5V where the larger one is 9V.

If you look at the power of the cells, you can see that the larger one can produce more than 5 times the power of the smaller one.

4.5V * 100mA = 0.45W

9V * 280mA = 2.52W
