$$PVDG$$ Thanks beer I prefer scotch but hey if it has character! I believe the main sustenance of the higher production % of these solar cells must be in the specific n-Type and super thin CZ layer that interweaves the induction plates, and combination of moving all the power connection to the rear of the cells. PVDG needs to incorporate these into their products to achieve a smaller power uptake footprint. They could virtually be used anywhere then.
