Glass is very rarely replaced and is exposed to 100% of the sunlight that will be around during its installation life time - shaded or not. That’s going to add up to considerable energy regardless of input cost.
Glass, sure, but what about these quantum dots? LED light bulbs were supposed to last 25 years, but everyone I know that has these replaces them well under that time frame.
The LED bulbs often fail due to the driver electronics, not the LED parts themselves. At least with large PV installations the inverters are separate from the panels and can be replaced.
