Good to hear, sounds like the panels should stay with the sun thenGeorge how about the aspiration fan is it a more robust/ functioning design vs. the 5n1??,,still driven solely off the solar cells?
The fan is driven by 3 solar panels aligned east, south, and west.
It's a very quiet fan, so I don't think it's running crazy fast, but the temps have been nicely consistent with surrounding stations.
One thing I keep meaning to check, but still haven't, is if using the DC jack powers the fan at all. It would be nice if it did.

Can you check this and report back?
Another thing, a concern is WHY did they make the top half black, is radiant heat going to be a issue?? .
