have shorter lifespan than poly or mono crystalline
Panels, they work better on cloudy days,and better with partial
shading eg. Stay shadow.
I have poly crystalline panel that are now 14yrs old & still
Mono panels the solar cells are made from a single
& put out slightly more power
Poly panels each solar cell is from multiple crystal silicon
blocks & put out slightly less than mono cells
Flexible or amorphous silicon panels are sprayed on to
the backing material & have less output again.
Because they are sprayed on they are very thin & more
Susceptible to damage & have a shorter lifespan
Yes they are lighter but nowhere near as durable
Some of the poly & mono panels have ten yr + life
as the manufacturers claim.
I would guess you would be very luck to get as much as
seven yrs from flexible probably a lot less
You pay your money
& take your choice?
