The plan is to use an Arduino controlled fan and dampers to only activate the heater when the panel temperature is higher than the crawl space. This could also be used in reverse in the summer to move the cooler night air into the crawl space to help the A/C out a bit.

Hi,
Here is a simple crawlspace solar heater I did:

It was more of a test than anything else to see how well it would work, and it worked fine.
I've since used that wall for a more permanent solar water heating system, but the air heater worked fine.
