This mostly seems to support my statement that the ROI is worse. You cannot discount the cost of the house entirely in the equation. Many people are not even home owners.

You may be right about the ROI in a strict sense, I just question why it matters.

A communal solar farm is not the same product as personal home solar anyway. When someone with surplus money decides to pay for their own solar it might be suboptimal ROI for them, but the rest of us get a little bit of solar benefits for 0 money.

And more importantly, solar starts replacing fossil fuels rightaway. No waiting for a communal, optimal ROI initiative to get started.

But of course, we should do those as well.

		What other sense could I possibly mean it? A home owner who puts PV on their home could instead have invested in a larger scale PV business and made more energy per dollar. By putting the panels on their home they have robbed us of electricity.
