I have a heat pump driven boiler and I do run it when the excess is available - it uses 500W, so I'm still left with a potential 2-2.5kW. I can of course set the boiler hotter, but then I'm just wearing out the components to lose the heat at night (since I don't need so much hot water).

I do have an EV charger, but no nearby neighbours yet with EVs.

However "sharing the excess" is an interesting idea, since everyone needs electricity. I could run an extension cable to the neighbour and let him run his washer/dryer from it at peak times.
