Constructed with high-performance aerospace solar cells. These are ultra-thin, only 1.7 mm, and ultra-flexible latest generation panels. Mono cell efficiency 17.25%. The panel consists of a sandwich made of a plastic support + solar cells + a UV-resistant epoxy resin surface coating. Fixing is done using double-sided tape. Connection cable with MC4 plug included.Version A: mono-crystalline panels.Version B: fitted with Sun Power top-efficiency cells. This results in more compact dimensions and 23% higher efficiency over standard cells.
