Stuff like that is regional
The satelites go around the world
May as well think of it as not as anything specific but as “the entire globe gets the same amount of bandwidth and its completely independant”
If it can support 100 people per km² then thats perfectly fine for a place where only only 10 people per km² live, but for a high density city where 10,000 people live per km²?
Its just not enough
(Numbers are purely illustrative)

Dams normaly have a specificly designed spillway as it could otherwise be VERY dangerus (the water removeing dirt at its base , possably leading to dam failure)
I doubt the solar panels were put on it tho
If water is just overflowing it entirely like a glass of water then shits so fucked that the solar panels just dont matter
