PV panel degradation [RE-wrenches]

Hi

 

Does anyone have historical data on pv panel degradation?  Is it safe to
say it is ½ to 1% per year?

Shouldn’t this be factored into the purchase, from a potential client’s
perspective? Let’s say a 150 watt panel hypothetically only puts out 120
watts real world, would it be a 1% degradation to get to the 25 year
warranty?

 

Thanks for the feedback!
