Over all my years of taking online classes for NABCEP CEU's This has been the most enjoyable and comprehensive class I have taken. Even more than when I use to give classes as an IREC Master Trainer.
Join the course, and I thought it provided a good informational update across a range of topics.
Actually I have run a solar installation team in Asia. I followed only manufacturers' instructions during installation of solar systems. After this NABCEP associate exam prep in HeatSpring, I have known about much more information and data about solar PV. I have decided to take some more courses about solar PV in HeatSpring.
