Yet the battery could produce more savings than the solar.
Electricity prices can vary by time of day, as demand varies. Charge it at cheap-o-clock, use it at normal times, you make savings.
It can produce more savings sure in terms of electricity costs, but when including capital, solar is presently much more cost effective. In my area some 6.8kw panels have a four year ROI.
This is entirely regional though. The further you are from the equator, the more seasonal variation there is in sunlight levels, and heating/cooling loads. Around here our solar production is minimized during the season when our energy needs are maximized. We also don’t have variable rate billing, though we only get partial credit for excess generation, so battery storage will never pay for itself until something changes.
