> batteries Not exclusively. A few power companies (like SRP) innovated here with TOU plans that have variable costs throughout the day. You can save huge amounts of monthly spend by moving energy intensive work to off-peak hours and by “priming” things ahead of peak hours, like over-cooling your house ahead of the peak window. The most costly part of an infrastructure build out is supporting peak-of-peak - that capacity exists year round to service the demand generated by peak mid-day usage during a heatwave in July. If you can “lop off” that peak - it dramatically reduces the infra build out cost. Peak-of-peak tends to correspond with sunny days: mid-day in summer. I could see battery-less solar being a useful tool there.
