I agree. I have DIY customers who know more about PV systems than a lot of
so-called PV professionals. Designing and installing PV systems is a continuous
learning experience. We are practitioners because, like doctors, we practice
our trade, expand our knowledge, and hone our skills. I tell people who wants
to get in the PV business to put a PV system on their own home. People who tell
me that they want to sell PV but can not go solar personally for whatever
reason have less credibility. They get less respect from prospective customers
who use the same reasons or excuses for not going solar. They either don't last
long in the business or are in it only for the money. Granted, there are less
operational nuances to a batteryless, grid-tied PV system than a battery-based
system or wind or water generator, but living with your work is essential. It
makes you keenly aware of unique subtleties and helps you better understand
your customers concerns.

For Off grid, no one should even attempt being a designer/ installer without
living for a full year on their own off grid system.
GT w/ batteries, you need off grid smarts and understand GT.
Training newbies, I can't imagine them being able to do anything other than
schlep modules/ do grunt work for a couple of years.
I could see a licensed electrician with a year of full time training being
able to do GT w/o batteries.
Most of the market and all the growth is in the GT w/o batteries, so I think
your training should concentrate there.
I've taught a semester long PV class, and all I was able to do was create
well educated consumers.

Hi gang
I was wondering, what percentage do you believe represents the ratio of
classroom training to field training for PV and what percentage you believe
should be performed by licensed electricians vs what is deemed mechanical work?
Residential Grid Tie w/out batteries
___% classroom- electrician
___% field- electrician
Residential Grid Tie w/out batteries
___% classroom- mechanical
___% field- mechanical
Commercial Grid Tie w/out batteries
___% classroom-electrician
___% field-electrician
Commercial Grid Tie w/out batteries
___% classroom-mechanical
___% field-mechanical
Residential GT with batteries
____% classroom-electrician
____% field-electrician
Residential GT with batteries
____% classroom-mechanical
____% field-mechanical
Any takers on the off grid market percentages?
Commercial w/ batteries is utility scale and I don't think it can be
quantified today as the projects are generally design build and perhaps hard to
put an exact # on these.
Thanks
