Solar now being the cheapest energy source made its rounds on Lemmy some weeks ago, if I remember correctly. I just found this graphic and felt it was worth sharing independently.

Further lowering panel cost isn't going to significantly cut that price. Cost of labor is the major part of that.
People always focus on rooftop solar, but it's horribly expensive compared to a field of panels. The economics of scale will almost certainly keep it that way.
What we should be looking at is community solar, where neighborhoods invest in a solar field together.
Wouldn't that be a less sustainable use of land?
I guess maybe not if we are talking tall building, where the roof surface area may not be sufficient for the entire building. But it would be a waste not to make use of all the unused rooftops
Yeah, in some countries, land is at a premium. No way would it be wasted on just solar panels. Rooftop installations make the most sense.
They are even testing putting them afloat on dam reservoirs.
I've always thought that in the neighborhoods where everyone lives in townhomes and mini apartments a shared multi floor parkade with solar and maybe also wind on top should be a thing. Even if the solar is just covering the parkade's power usage.
