My impression of solar in the western US, at least, is most solar arrays do not charge batteries. They are linked up to the power grid instead and solar owners are payed back a percentage of what they’ve contributed. Im personally an advocate of battery banks (And have them in a boat and rv) but it seems if every single family home had a battery bank there’d be a large surplus of energy created but not always used (aka it doesn’t scale well). If anyone has information otherwise I’m all ears this isn’t my domain
