Yeah, having a functional energy market definitely helps make these things make sense. We have half-hourly, bidirectional metering, and being able to save solar and sell it at a good rate means the payback period is looking like 7 years for us. Our grid is also experimenting with paying people to borrow their batteries for predicted high usage events, up to £25 for one event. I guess this means nothing if you can't access it but hopefully it's a model that spreads.
