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.
- jbob2000 7y agoGlass, 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.
- the8472 7y agoThe 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.
- jbob2000 7y agoExactly. That’s my point with these glass-quantum dot windows. Glass is fairly sturdy; are all the electronics?
- Dylan16807 7y agoThey're probably not getting superheated like a light bulb.
- root_axis 7y ago> everyone I know that has these replaces them well under that time frame. Survival bias. Nobody is thinking about the bulb they haven't had to change in 20 years.
