Why solar panels cannot realistically power the electricity grid

Why solar panels cannot realistically power the electricity grid. "To power 100,000 homes for one hour, you need 50,000 tonnes of solar panels." "If I want to produce this hour of electricity in the evening when the Sun isn't shining, well then I need... about two basketball courts worth of batteries." "But of course I have to charge these batteries, so that means I need additional solar in the grid so that we have an excess to charge them. So we add another [10,000 tonnes] of solar panels." "This is for one hour."
