I don't understand what is written on the Wikipedia, it is totally different

Every water molecule hydrolyzed donates two electrons which are ultimately accepted by one NADP+ molecule (along with two hydrogen ions). Thus for every 6 water molecules hydrolyzed 6 NADPH are produced. The ATP:NADPH ratio in noncyclic photophosphorylation is 1:1, so 6 ATP would be produced as well.

The Calvin Cycle requires 18 ATP total to produce two G3P molecules (which form one glucose molecule), so the rest of the ATP needed probably comes from cyclic photophosphorylation.
