Not necessarily that brand specifically but something similar?
Yes, I mentioned that in my comment. They are quite an investment, and they're impractical to place in many houses. So it's not always an option. I personally have the space. But there's some ongoing projects that make it impossible for me to currently install them.
A lot of houses here are terraced, so actual room for a powerwall is very limited. You usually only have a few meters of front and back exterior walls, with big windows. And any apartment owner is going to have to fight with the HoA to install something.
Not saying it's impossible for all houses. But I was replying to the "why don't we cover all buildings with solar" sentiment.
That process is expensive enough to make a purpose built option approximately equal in price. The companies selling this sort of system are pretty smart with pricing. Same for any kind of solar/water storage/etc solution.
No, you likely can not jerry rig this yourself and burn down the neighborhood.
In densely populated areas clearly that can be a problem, for solar and for heat pumps
Could a potential solution be neighborhood scale installations?
We do not be isolated from each other
