last 7 years
My small panels have a 20 year power output guarantee.
That is three times longer than what you suggest.
I am confused about your data. I have done a lot of research on solar cells and none of them have a seven year output rating.
Please do some research on how a solar cell works.

For clarification I meant to say, please do some research on how long a solar cells lasts.
My bad man. I just noticed it.
It seems that after looking a little further into it. Most solar cells power output lasts up to 30 years. It stated that some of the thinner cells
only have a warranty of about 5 years but put out power for twice that amount of time. I am curious as to what cells this is referring to because I
have never personally seen one.
Sorry I cannot link anything I am on a cell phone.
I do know that the amorphous silicone cells have a faster degradation time than crystalline.
