Sunlight and Potatoes

So I have grown many many many many potatoes - but I've always done so in pretty large fields. Full sun or close to it. I have a perfect piece of ground that about 12 x 18 I was going to throw over entirely to potatoes with the hopes of getting 150 -225 pounds out of it. It get an hour or two of pretty good morning sun then a couple hours of mottled sun then 4 or 6 hours of almost total shade followed by 2 or three hours of direct late afternoon/evening sun. Thoughts?

They'll produce, but somewhat less than if it were full sun.
