    How can the price go negative? There’s always going to be maintenance costs that have to be covered if nothing else.

      It’s like a dumpster filling up, where you have to pay a waste management company to come haul that stuff away, at least if people can’t find a way to take it off your hands for free.

      Because its deterrent for people to supply electricity when its not needed.

      I have a 10kWp system, sometimes I have to pay for the electricity I create and I dont use. There’s no maintenance costs in my system

        Who are you paying when that happens?

        Also, the panels never wear out or get damaged or have to be cleaned or anything? This isn’t me trying to make a point against solar, I’m just questioning how there could ever be absolutely no cost to having it. More in the sense of an electric company rather than private owners.

      The idea is there such an abundance of energy that they are willing to pay you to consume some of it to keep the net stable at 50 (or 60) Herz.

      In practice, there are always taxes and surcharges that the final prices is not negative, but is lower than the surcharges themselves.

      Too much energy is not good for the system, so there must be a way of compensation.

        Can they not just cut off some of the panels with some sort of breaker when the output exceeds consumption/storage?

      The system is overloaded so there is no need for more power, in fact putting more power into the system has a negative effect. So there is no value to putting more power in the system and it may actually have a cost.

        The system still has physical hardware that has to be maintained, the company has to charge it’s customers to pay for this maintenance at the very minimum. As well as any other cost to deal with the excess power, although I don’t see why that couldn’t be mitigated by simply disconnecting excess panels from the system. That price should never be negative. It makes no sense. A negative price would mean they’re paying their customers. For what?

          Livin where it was an actual thing - they actually “paid” in the form of counting returned power as borrowed. So when you powered the grid, supplier counted energy you supplied and then promised to return the same amount when you needed.

          They backed off of it but my friend caught that version and he was pretty hyped about it. Even when his solar panels will die, he’s gonna be set for at least next decade on that payment lol.

          More generation than load makes voltage go up. More voltage has varying effects on equipment, ranging from no problem to exploding in a shower of molten metal.

      Here in Sweden our electricity provider gives us a real time view of consumption and prices. When we charge the car during peaks of overproduction we get paid and the amount on our bill goes visibly down. It usually happens like 5-15 times a year during summers, and occasionally also because of excess winds on the farms year around.

      prices do not actually go negative if the solar parks are correctly installed.

      the issue is simple: the solar parks forgot an “off” switch, so they continue to push energy into the grid, even when there’s no demand. so that destabilizes the grid which is bad, so the grid produces “negative electricity prices” which just means they pay someone else for taking that energy out of the grid to stabilize it, and they’ll also charge the solar parks for pushing more power into the grid than the grid can handle.

      honestly, it’s just a construction mistake. the solar parks should obviously have a simple “off” switch to stop pushing power into the grid. they just forgot it during installation, end of story, no big deal. this is probably not going to be a permanent phenomenon, i’m very sure.

      Power grid stability.

      Over generation and under generation can destabilize a power grid.

      Thats why when there’s over generation it can sometimes go negative because that power needs to go somewhere so they’re willing to pay people to consume it.
