And add the cost of batteries.
- walrus01 5y agodoesn't necessarily have to have batteries, as in many common installations, daytime PV is used to flatten the curve of fuel consumed by regional coal, gas, other fossil fuel power plants servicing the daytime peak of load demand. Conveniently enough in many places with hot weather when the peak of load demand is occurring mid afternoon with everybody's air conditioner running, the PV system is also performing at its best. Or can be connected to something long distance similar in tech to the pacific HVDC inter-tie to move power long distances to where it's needed, or can be used to pump water uphill in a nearby pumped-storage hydroelectric system.

For that, SPS at SpaceX Starship launch costs has a decent chance of being cheaper than ground-based solar plus the the various extra systems required to turn it into reliable power.
