You build a solar farm out in the desert it is up to you to maintain it and the supporting infrastructure (transmission lines).

Put a solar roof on a home and it is the homeowner's responsibility to maintain it.

There's also the values of geographic distribution:

* on site transmission cost is $0 for power used

* the effect of a man-made or natural disaster in one location is contained: throwing a breaker for maintenance at the Arizona border doesn't shutdown power across an entire region: https://en.wikipedia.org/wiki/2011_Southwest_blackout.
