I think this would work for the summer months. Overnight storage is manageble/cost-effective by load shifting/battery storage/etc. This is now estimated at about $100/MWh ($0.10/Kwh).

Seasonal storage is a completely different story. For my own panels, production in Nov/Dec/Jan is about 20% of that in Apr/May/Jun, and this is typical. That means that you either need 15x solar capacity of what you need on a sunny day, or enough storage to bridge those 3 months, two orders of magnitude storage more than we would need to store electricity overnight.

Or some combination of the two. Obviously sounds expensive but 20 years ago this would have been fiction. I think it’s entirely likely that energy storage and production will continue to fall enough in price to make this realistic.
