I get where you're coming from, but let me correct some of your numbers for other readers:
> you replace bricks every couple hundred years, but solar panels every 10–20, right?
Old panels perhaps, but modern solar panels come with performance warranties that guarantee they will be producing >85% of their initial output after 30 yrs.
> 2000W solar panel is like $300 or something and it's half the size of a door
2000W solar panels generally don't exist, so I assume that's a typo for 200W? Modern utility scale panels top out at ~700W with dimensions of 2.4 m x 1.3 m, however rooftop panels for commercial buildings are in the 500W range and ~ 2 x 1 m (so yeah about a door). International wholesale prices for these from Tier 1 manufacturers are now < $0.10 USD / W (although from what I understand more expensive in the USA).

Housing co-ops would be incentivized to implement those features. Our society should make it easier for co-op of all types to be created and thrive (such as through taxes), but especially worker owned and housing co-ops.
Unless a building is crowd-funded by the future tenants with the promise of no electrical costs, and also the future tenants expect to live like 100 more years, I can't see how this could happen, short of the eradication of private property and the government constructing these things.
