Hot air solar panels

Hi Tom..
I have a 2000 SF retail space with approximately 50 linear feet
of southern exposure that I would like to supplement my existing heat with
hot air solar panels. I have been looking for info online but everything I
come across is either for hot water or electricity. What are your feelings on this.
Thanks, Jack

Hi Jack,
Check out the website: www.builditsolar.com
It is an affordable project if you have the place for the collectors.
