There’s another consideration here, the video is saying used panels tested and used for another 5 years at the recycling facility then taking those panels out and recycling them using recovered used panels from another site. For some time now Boron has been sputtered onto solar PV cells to stabilize them from micro cracking and has shown up as changing the degradation characteristics of solar PV panels from 3% degradation the first year and 1% degradation each year after. Now with sputtered on adders solar PV crystalline cells have typical 2% degradation the first year of use and 0.5% to 0.25% degradation each year there after. Today a modern utility scale solar PV panel of 500 watts could last 30 years and end up 419 watts after 30 years of daily use. New technologies as part of the quality control systems used to detect faults in crystal solar cell wafers allows rejection of wafers with too many defects and some burgeoning laser techniques that have had some success at taking wafers and “annealing” the wafer to correct weak spots where micro cracks can start. More modern solar PV panel manufacturing techniques like “shingling” cells, using IBC manufacturing techniques to help keep solar PV cells cooler overall. This may prove over the long term TOPCon cells and IBC contacts may create the 50 year solar PV panel in use.
