Re: [AFMUG] Solar panels
I think they come from solar farms. They must replace whole sections if they get damaged, or something like that. A lot of them say they have the labels removed, so they can't be used for grid-tie, but for off-grid projects, I can't see any obvious reason why it'd be a bad idea, other than that they're presumably going to have a shorter lifespan than new ones.

Re: [AFMUG] solar panels
Is it age from production, or age in use? I assume the shelf life is indefinite. Aside from technology change, is age a matter of elemental exposure or is there components that degrade?

Re: [AFMUG] solar panels
There must be a way...
My Father-in-law works at a lab at Cornell where they wanted a number of
panels with all exactly the same efficiency for a research project. Not
sure the test method, but obviously they figured one out.

Can you test efficiency reliably, like set up a uv light and specified
distance in dark room and measure output? As they age what's the curve
look like on efficiency loss?

Age for sure. 20 year old panels will not have nearly the output of new ones.

How do you guage a level of used on solar panels? Age? Visual issues? Can you
test efficiency reliably, like set up a uv light and specified distance in dark
room and measure output? As they age what's the curve look like on efficiency
loss?
