As you can see the low fan setting will help for payback. The high setting does save but it would take a very long time to get payback.
The payback is actually better than I thought it was going to be.
When you are using solar to cover all your power needs you have to look at how much solar would I have to add to cover this item.
Thanks for asking the question I am glad I did the math.
I won’t be leaving it on 24/7. It will be controlled by my home automation. The appliance that controls that knows the temp outside. It can get the temp inside and I can run the fan based on that info. It is totally programmable
