We already have something better, it just requires large facilities because of thermal demands.https://en.wikipedia.org/wiki/Sodium%E2%80%93sulfur_battery
The japanese use it to lighten loads on the grid in remote areas. I have frankly no idea whether that can power an industrial economy, but wikipedia says the following>As of 2019, the maximum power of battery storage power plants is an order of magnitude less than pumped storage power plants, the most common form of grid energy storage. In terms of storage capacity, the largest battery power plants are about two orders of magnitude less than pumped hydro plants.
If hydro plants can't be made large enough to get us through even a single day, I stongly doubt batteries can.
And the general fact remains that all of your experience and arguments is about a simple residential building, a energy-saving one at that I guess. How are you heating? Don't tell me you heat your home with electricity (it works, but not on solar power). Have you thought about logistics (Cars, Trains, Trucks, Ships)? What about all the myriad industrial processes necessary for our modern economy, including the part that supplies your solar cells and batteries? Many of which, btw. we have outsorced to china and other places with low energy costs. Most of which comes down to coal and other fossil fuels in the end.
