Just out of curiosity, What kind of batteries?

Sodium ion tech is a game changer. You can completely fill them and drain them without damaging them, so their practical capacity is higher than lithium ion, for the same theoretical capacity. Plus they're a fraction of the price, so you can buy much more capacity for the same price, or buy more panels with that surplus.
As a bonus, no risk of catching fire, and in theory we could make them in Aotearoa from local materials.
