You will most likely get all the cells (337) in good working order! It would take 24 cells to make a 12 volt panel. Each 12 Volt panel would be a 96 Watt panel. This would produce 1248 Watts per Solar Hour!
There are lots of youtube videos on how to make and wire your own solar panels! Please see the photos for an example of the cells with "chipped corners" but most are in perfect order with no damage or chips.
Most of these cells already have at least one set of "tabs" added to them and they can be extended to connect them to each other. Please let me know if you have any questions.
