If it's a full size wafer it'd be 30cm ~12in

Source? I've never heard of solar using 300mm wafers. I think the largest is M6

Those are the largest silicon wafers. No idea if they're used for solar

They're not. Solar wafers are pretty different from wafers for IC / transistor fab. They are much thinner, rectangular so they can pack well, and are generally sold rough cut rather than polished.
