I prefer to have professionals deal with 600VAC.
One of the "Stupid" things in solar, they are upping the DC voltage. 600VDC used to be the standard. They moved to 1000VDC and are now going for 1500VDC. This is to lengthen the solar panel strings and reduce the number of Grid-tied inverters.
MOST electricians are only good for household wiring. (240VAC)
MOST industrial electricians are only good for "low voltage" (600VAC)
Very very few are trained for Medium Voltage and above. And they are usually in the power generation/power transmission industry.
I think the solar industry is putting a LOT of electricians at risk with Medium Voltage strings.
The threshold of Medium Voltage is where human skin resistance is no longer a factor. Above 600 volts skin no longer plays a significant role in resisting current flow through the body.
