When I look at it I notice that current variation in cost per mwh is much larger than transmission line losses or storage losses.

You look on a map and you notice places where the days of sun shine aren't very conductive to solar are usually within 1500 miles of places where solar works great. Seattle to the Mojave desert is 1200 miles for instance.

And as the owner of a solar off grid home north of Seattle, I can tell you solar works fine there too. ;)
