I think the disconnect is that with starship they’re targeting >200 tons/200,000 kg and $2m-$10m/launch, so the very optimistic case is more like $10/kg. Also, the production of a panel in sun sync orbit is many times one on the ground, doesn’t suffer seasonality/weather, and doesn’t require battery storage for smoothing/time shifting, so you’d need to deploy many times the number of panels on earth. Our home array in North America over the course of the year generates something like 1/7th of its theoretical capacity, overproduces in the summer, and underproduces in the winter.
