I’ve been hearing about heatspring since the first PV course I took, I have not been disappointed. Thank you, heatspring
This is a great free course to gain a broader perspective on PV design and installation, and to get started on qualifying for the NABCEP exam!

I'd say to you all is to focus on yourself and the information that is being given to you.
The course is a very good powerful and a good site
