Solar modules deployed in France in 1992 still provide 75.9% of original output power

I love seeing stuff like this. Iirc, panels are given a 25 year lifespan. If most panels will last this long and longer, it would only make sense to replace/upgrade when they actually break or there is a significant enough increase in efficiency to make it worth the investment. Not unlike the batteries in evs lasting longer than even the original engineers estimated.
