Need help with Heat pump

Is this auxiliary heating for the heat pump? Solar panels connected to ducts going to heat pump. Dayton system running what looks like a fan. Not sure how this is working. Recommend have system serviced and explained operation to clients. Did notice several registers not working.

Looks like some handyman/homebrew stuff right there.

Damn there is such a thing! It’s called Solar-hot-air-collectors. Not sure what to tell the buyers.

I think many solar collector’s are less then professionally installed ,
I recommend you get this installation Checked over by a professional Installer

I inspect solar electrical panels, solar water heater panels, and solar pool heating panels all time.

Solar-hot-air-collectors is not something I’ve seen.

This is why I love this forum, I still learn something new everyday.
