r/technology – Flexible solar panel sticks to roofs with low weight bearing capacity, no racking, 20.9% efficiency


The biggest problem is that I don’t see this lasting. This technology has existed for a long time already and is used by people on RVs and boats. The biggest problem is the lifespan is pretty short because they are not racked or protected by glass the heat and the elements tends to be a lot harsher on them. So things like even blowing dirt will slightly scratch up the top layer since it will be some sort of plastic wearing it and reducing efficiency.

I would guess that these likely have under 10 year lifespan compared to the 25-30 of conventional solar.

It really comes down to the cost of the system, if they can get it down to 25% of what a conventional solar system costs it actually has real potential. I would probably instantly put it up on my roof if that was the case.
