I just discovered this group and have a question.

I'm considering getting some solar panels to power a remote cabin in
Arizona. What I wonder about since we don't have a lot of actual cloud
cover is the effect that jet contrails have on the solar output.

I read a Australian study about the effects of contrails on solar
panels that said some kind of chemicals in jet exhaust could effect
panels. I think it was cone somewhere in southern Austrailia in the
mid 1990s.

Thanks!

Close to nil. They simply don't represent much in the way of cover. Ordinary
clouds are far more relevant.

Statistically significant for sure. I think we're talking about a percent or so.
Not really a big effect for solar power.

so.

higher than 1% although I might be wrong. Like I said, the information
I read last year says that the study in Australia found a lot more
than that. I cant find the study with a google serch anymore. If
anyone here is there, let me know if you have herd about this.

Here are the sites I've found. Some are pure crap.

I have read that a high thin overcast defuses light in such a way as to
increase efficiency at 9AM & 3PM etc. for a net gain.

Soot is soot.
