>Rooftop solar never really made sense in the big picture kind of way. I think it's in the big picture it actually does make sense. True it's not the cheapest, but it is the fastest way to actually get solar panels into sunshine and start solving our problems. The additional cost is paid mostly by "volunteers" instead of having to raise taxes or wait for some corporation to make a move, there is no NIMBY-problem since it's actually the BY-owner who makes the decision. You can mobilize thousands of companies (solar panel installers) at once all around the country. Rooftop solar grows by about the same as a nuclear power plant per year in some countries. Finally the resulting power generation is geographically distributed so that no single rain cloud can cover the entire "power plant". I think larger projects run by governments and large corporations should be focused on generating gas or building battery storage, so that some of that cheap rooftop solar and other renewables can be stored for nighttime and winter, instead of being sold for negative prices at certain times.
