Hmmm... without experimenting myself, I can't argue that point.
On the other hand, with the effect of having an array with a consistent three to five elements running at or near their peak power throughout the day, logic of cause and effect would say that overall power produced would be equal to or greater than a fixed array with the same number of total elements even though the the peak overall power would be higher on the fixed array for an estimated 30% of the time. Just as an AC signal's peak might be +/-160V (320V Europe and elsewhere) the RMS is more like 120V (240V) per cycle. If the curved array can produce the 120V as a DC equivalent, the overall effect is a stable and constant power throughout the day.
Yes, it is possible that a fixed array may reach a balance point on cost of assembly for the power produced, but if this boy's concept is confirmed, then it's possible a less expensive array configuration may result.
