Hey Kirk, We have sold sanyo then Panasonic modules for over a decade. Not only were they highly efficient, they were the last truly high performance modules in the US. I have exhausted my search for them, only 3 left in stock. Panasonic will not return my phone calls or emails.
There are dozens of China companies making small and expensive modules using SunPower cells but I doubt any are listed. I managed to buy some 327 and 435 Watt Sunpower modules dirt cheap "from a guy". These were cosmetically blemished laminates that someone framed. Isc tests show they are producing rated power or higher but the frame is light and the cell surface has blotches under the glass. No listing on these either but my off grid customers in Mexico love them for the performance and cheap price per Watt. Does anyone know which of the 60 cell manufacturers have the highest module efficiency?
