I agree, there are some mitigating factors though. One nice thing about solar in warmer climates is that its peak output is in line with peak air conditioning demands. On top of that if the solar is installed on the building roof it can lower the thermal load on the building. A double win. Also in a ideal world we would have a world wide grid where solar energy is being routed around to where its needed with much less need for storing for night. Its always sunny somewhere right? There are of course line losses, not sure how that would stack up to battery round trip losses.
