Solar cells do decrease production with age.
The better rigid mono and poly panels provide guarantees that give some idea of the slow rate of deterioration.the guarantee usually specifies something like 90% output at 10 years and 80% at 20 years.
cells used in some lexible solar panels
deteriorate much more rapidly
The new flexible panels like Solbian use very similar cells to the rigid panels and should have a reasonable life, but we will not know untill they have been on the market longer.
Failure is likely to come from mechanical causes such as delamination
, damage to the wiring
, loss of transparency of the clear cover etc rather than the slow gradual inevitable deterioration of the solar
