Our semi-privatized energy grid

3. It's not that simple.

First off, line losses are from alternating current, and capacitance to ground is mostly due to very high voltages.

Individual systems approach is inefficient. Larger is almost always more efficient, even if it's just thermal. Plus, inverters at every house, along with lots of other things, is problematic from many aspects.

I am not an electrical engineer, so I can't say what configuration comes out of solar array sites. I don't know if dc lines come out of the big solar arrays. I think they are close enough to the source that they can invert it at the site, and use the existing grid.
