Yes, Steven, I'm hoping that when the time comes, between the coop having had to ....er..."cooperate"....with more homeowners in recent years on intalling grid-interties, that they will be more schooled at it. Minnesota is a "net metering" state and the public utility commission is pretty strong on getting renewable energies online at the industrial, community, and residential levels. Even the governor of our state was ready to go to lawsuit battle with the state of North Dakota over Minnesota's mandate to have a certain percentage of electrical energy be renewable: Since North Dakota is a big coal producing and coal-sourced electrical generator for the region, they were balking at Minnesota's sudden decreased market for their power. And thanks for the DC/AC differences on line loss. Somewhat humorously, I first came across that concept in a history course where I think it was Edison wanting to go with DC, but someone else noting AC would be better for long-distance power transmission.....Ah, here it is: https://en.wikipedia.org/wiki/War_of_Currents
With regard to your's and R Scott's notion of " roof + holes usually = bad".....LOL.....Yes, I quite agree as would most. What I would envision is one hole centrally located for 4 panels.
