> Probably not worth it and I'd expect 3 days to be overkill. But a community that was double our size will have a cost of about 25k per unit for 1.5 days of power - which doesn't sound too bad to me.
If you're not looking to go completely off-grid, I think you want to double it again. At basic level, battery pack is there to soak solar power during a day and give it off when the solar is down.
16 hours is enough to cover most or all of that..
I think the model could work if the local community basically "sold" the battery storage capacity to the users.
Pay few cents for kWh to store it for 24 hours, anything in excess can be sold back to residents at slightly lower than market price, producing some money for maintenance and upgrades.
