Those potentially have the same issue. The solution to filling the gaps in production from renewable sources is not necessarily more panels or more windmills, it’s having energy storage somewhere to keep surplus energy when it’s being produced (e.g. during the day, or when the wind is blowing) available to be used when it’s not.

So in your example, each home could also have its own battery bank. Or, a larger battery bank could be placed somewhere on the electricity grid.
