It depends what type of shade you're talking about; dark shade, produced by an object real close to the panel or light shade, like from a tree that's farther away.
If the shade is dark, the bypass diodes will conduct. If the shade is light, the diodes will not conduct.
In a series string you're only as strong as the weakest link. That means in light shade the string current will be as little as the lowest producing cell. Series panels have a real disadvantage with light shade when the bypass diodes no not conduct.
I would go parallel, or perhaps series/parallel.

So, if series/parallel is not an option, which way is best, where partial shade is concerned; series or parallel?
Thanks.
