Architecture transition moved faster than depreciation
TOPCon displaced PERC from clear dominance to effective obsolescence in roughly three years, which is faster than any previous transition in this industry and considerably faster than the equipment installed to make PERC cells could be depreciated. Around 180 gigawatts of manufacturing capacity was stranded in the process, much of it built within the preceding five years. TOPCon modules now grow at 8.1% against a market rate of 5.4%. Manufacturers who moved late carry both the write-down and a product customers increasingly will not specify at any price. Nobody depreciates a line properly now.
Market Impact: Grows without any of 3 subsidies
