I'm Andy from Rep. of Panama, studying to be NABCEP PV designer installer certified. One of the most important tools is your "Understanding NEC Requirements for Solar PV Systems", by the way - very simple and specific. Drawings give you a clear understanding. Congratulations, knowledge expands when you share it, thank you.
Mike and Team, you are the best! I just passed the NABCEP Certified PV Installer exam and I couldn’t have done it without you. While I am strong in solar, the NEC was pretty mysterious. When I finished your book on Understanding NEC Requirements for Solar PV and got 90’s on both final practice exams, I knew I was ready and had the knowledge and confidence to pass. Thank you and bless you all for the outstanding work. You can bet I will be getting the updated version for the 2014 code cycle. My best to all and again THANK YOU!
