Like 90-95% of the world population lives at latitudes that get better solar resource than Northern Europe, such as Germany and most of the UK, etc. The seasonality isn’t that great and you can displace like 80-90% of grid energy use affordably with a battery (at least in bulk prices) even without net metering. 15kW of solar, which is about what you can get with a roof full of solar panels, would be enough to handle the household energy including heating, cooling, cooking, and commuting in electric cars for my household of five. And with tandem Si-perovskite cells commercialized over the next couple decades, etc, that amount could climb to ~20-30kW for the same roof, taking care of seasonality effects, etc, except at very high latitudes. I love nuclear, too, but if nuke-bros are gonna make excuses for NIMBYing solar roofs, I don’t want any part of that.

I.e. the time during which you would be most likely to heat your home and charge your car? Sorry for "NIMBYing" you with the duck curve.

  I mean, storing the solar in Lithium Iron Phosphate batteries in bulk only add a few cents to the cost of electricity. I even mentioned it earlier in my post, which you ignored: > …you can displace like 80-90% of grid energy use affordably with a battery (at least in bulk prices) even without net metering. But no point in doing that while solar penetration is low, which it still is in my area. As far as level of discourse, yeah, that’s precisely my point. Claims like this are so far from true for the vast majority of the world that it lowers the level of discourse to misinformation and slander: > … Having solar panels on a random home will almost certainly be worthless because most major urban centres are not in solar-efficient areas.
