Mike has become, or should I say, I have just seen, that he is the standard that both contractors and inspectors view as industry standard for learning, teaching and working in this ever changing solar industry -James E Callison

I find the training materials and the recent book on the 2014 NEC Photovoltaic System Requirements are excellent. I consult in my design work - great reference material! -Michael Flahie, P.E.

For electricians nationwide, the name Mike Holt has long been synonymous with top-notch, Code-focused electrical training and publishing. Both he and this new book are exceptional resources upon which the solar technology workforce can now rely to improve the code compliance, safety and performance of PV systems. -Bill Brooks, Principal Brooks Engineering
