There is no such thing as negative energy price, unless you're retarded? Why would you pay someone to take your excess energy, when you can just dump it into the atmosphere through a resistor heating element? They are not that expensive, even if you have to finance one. Of course you might be benevolent and give it away for free, or even exert some effort out of love to they neighbor, and pay some for him to take it, but in a selfish capitalist view you can get rid of energy very easily, it's not like trash that is costly to get rid of.
You might not have a massive resistor handy at the instant you need it, but I suspect subsidies will play a part in this. If you get paid a certain subsidy per unit of electricity you produce, in addition to receiving whatever the wholesale price is at the time, you could still end up turning a profit by paying someone to receive your surplus electricity. (In Europe, there are also obligations for power companies to get a certain % of power from renewable sources - so it could be better for them to take this power now, giving it away for free or even paying a big industrial customer a tiny bit to use it, just to meet the government targets.) Hopefully, dumping that power into your own resistor bank doesn't earn you subsidy payments!
