africa is building a whole lot of solar panels to secure its energy supply. it's cheaper than fossil fuels, decentralized, doesn't require much of a grid. and works even when the officials are corrupted.

you don't need to run 10 km of cable. the solar panels are on the roof.
Or within a mile or two for fields of panels instead of being networked dozens or hundreds of miles from a central energy production center.
The ones in the picture are not on the roof.
In any case, I don't think that really makes a difference ultimately. Rooftop solar doesn't make that much power in the grand scheme of things. It's proper facilities that make the real power, and those are usually large solar farms, which are built over (usually rural) land dedicated for that purpose and do require more than 10km of cable to connect to the rest of the grid. Just like any other power plant, really.
I mean solar is great and all, I just don't see that being a real benefit in any grid where solar is responsible for any significant percentage of generation. Or am I misunderstanding the argument entirely and talking about something else?
no, the thing is, in the US sure utility-scale solar farms are what generates the most power, but i have read two articles about how people in africa and in the middle east install their own solar panels on the roof or close to the house to produce their own electricity because the grid is so unreliable. so you see, people make do with what they can get. and if grid is not available, then suddenly rooftop solar becomes a competitive option.
