I got my basics down in tech college in electronics, got a job installing/maintaining production equipment in the newspaper industry, worked with an electrician for a couple years and spent a good amount of time with him doing hands-on work under his supervision. I did learn to program programmable controllers on my own, but had a basic knowledge of ladder diagrams and logic from tech college. I had to learn basic computer skills to shut down the computers to repair/maintain the drive motors, showed them that I was comfortable with that equipment and from there was given the opportunity to move into IT. While I did learn a lot on my own, I also took the educational benefit my employer offered and went to school for training in operating systems, network, database, installation, design and operation, etc. I also spent a good deal of time at factory training facilities on the east and west coasts for our near continuous upgrading of production equipment.
Schooling is important. Learning from someone on the job is important. In a mission critical 24/7/365 operation, I'd be hesitant to let someone learn on their own through experimentation on live systems or processes. Been there, done that, cleaned up the mess. They had really good intentions, but did not understand the ramifications or scope of their actions should it fail.
I second the above statement about learning on the job. The Journeyman/Master/ apprentice relationship (established largely in union training) is the most effective training in a skilled labor career that matters. As a retired electrician, I can attest to the value of hands-on learning under a journeyman. Theory is needed but actually turning wrenches, turning wirenuts, layout of a jobsite is best learned from someone that has done it before.
On the "domestic content" solar note:
I installed a 7.5kw array on my home 3 and a half years ago.
The Mission Solar panels were manufactured in Texas.
The inverter and d.c. optimizers were from a company in Israel.
The Sq.D disconnects were from a formerly American company, now French.
The Seimens, (Gould, ITE) circuit breakers are from what too, used to be U.S. are but are now German, I believe.
The conductors, solar panel supports, junction boxes, conduit, and every item in this install was purchased with "built here" in mind.
This CAN be done. All of the gnashing of teeth over the "gubment's dang energy policies" is largely (and frighteningly) reminiscent of the Japenese cars coming to the USA in the 1970's. People were smashing cars with sledgehammers.
And in the 1990's when 'Tram-Law' stores were growing in number people were able to buy more imported goods for less. And they do. Price seems to be the prime directive.
To support American workers, do due diligence on where the products come from.
I understand the appeal of the inexpensive. (In fact my bride calls me " the only thing getting cheaper nowdays").
