I meant, as the array of panels covers the top half of the airship, I wasn't sure if the welded Array was being treated as a single flat panel or a dome that would block parts of itself from the light. By breaking them into left, right and top groups they would more naturally be treated as flatter sections that could have different sun angles. Ah, I didn't conceder that, thank you. And you were right, While welding them did decrees lag somewhat from fewer physics calcs, the improvement wasn't nearly what I had expected. On the other hand, now I am wondering if it WOULD be able to handle the domed shape for the sunlight calcs? So many experiments to run. In any case, after testing in flight I have come to realize that the array actually produce more energy then I could use even in the most adverse sun angles, and have redesigned the airship with less then half the panels.
