Mostly Self-installed is not self-connected.
Typically, you would only need an electrician for 1% of the work,
essentially permit/sign-off and final live connection.
Cost can be approx. 100-500$, depending.
The contrast is to a "fully built", where a contractor "designs",
"permits", and builds everything, typically charging 3000-13.000$ for
the "work".
99% of PV work is not complex and does not require any special skills
and tools, and can be done by any general building contractor.
Or HVAC outfit, roofing contractor, etc.
Some conventions vary.
Example (from Spain, similar mostly in the EU):
IF e.g. I wish to install a large 20 kW 3-phase charge point for an
electric car (Tesla) (, or a large 3-phase PV system (has many more
ramifications).)
There is nothing preventing me from installing the charge point,
ducting, cabling, relays, etc. using approved components widely
available from supply houses.
I can buy all the bits, and put in the eletrical boxes, connectors,
plug, relays/GFIs etc. whatever, myself, as needed.
I mostly wont need to do an upgraded electrical drawing for a single
chargepoint.
Cost of components about 250€.
The electrician comes in when everything is done, and *only* connects
the 3+1 wires from the additional chargepoint to the national electric grid.
He might need to file an permit ar additional doc, or not.
Typical time, 20 minutes, typical charge , 100€ or so.
Total cost: 350 € or so.
IF I hire an electrician to do *all* the work, total about 5 hours, and
let him sell me the components, the pieces cost about 1000€, and he
charges about 5-1000€ for the job.
Total cost == 15-2000€.
We do licenses and permits for customers routinely, and are quite
familiar with the legal processes.
All work is done according to the local codes, and fully permitted.
Fwiw...
Most electrical projects in general that charge, heavily, for "design
work" are just copies of old stuff, with new customer names and data
search-and-replaced.
