You are assuming no change in solar cell technology in 50 years.
That's not realistic.

They won't be manufacturing solar panels for much longer.
What's coming is a spray on plastic coating containing solar sells.
You will be able to paint your roof and walls with solar cells.
Probably windows as well, if it is made transparent.

Google on something like 'spray on solar cells'.
