Dealing with power from solar panels is easy: you disconnect them (curtailment). So it's not a problem.

Have you ever wondered how is it possible that the price goes negative? Why would someone pay you to use the energy they produce? Logically, the price shouldn't go below 0 (*) . The reason is that the government gives incentives for each kWh produ ed. So if they pay you 0.10€/kWh, you'll be happy to pay people up to 0.09€/kWh as long as you can keep producing, since your marginal cost is 0. Basically government incentives are producing this situation, paying people to produce electricity nobody wants. It's also the reason why production is far from consumption: the incentives never were designed to push to generate useful electrons, just electrons, even if they cannot be moved to where they are useful. We need to rework how incentives are provided, because this is ending up wasting a ton of public money!

(*) except for power stations were they cannot physically turn it off, but generally they wouldn't be able to produce enough energy to define the marginal price

In that case the government should pay incentives when purchasing an electric car. That way the electricity being produced on sunny days can be stored and used when it is cloudy. Electric cars will also be spread out geographically, quite in line with solar panel installations so that solves for regional and network issues too. And as an added benefit we use less oil (less combustion cars) and less gas (we charge when it is sunny and not when we produce electricity with gas generators).

By using less oil and less gas we reduce CO2 emmissions, save money and are less dependent on other regions far away.

I wonder if the excess energy could be used to do things like run carbon capture (although I've read that this is very much a pipe dream, that it'll take several magnitudes more carbon capture facilities to counter what we're currently producing).

In a very tiny Canary Island, their battery is many many tonnes of water pumped uphill when they have windpower: https://www.youtube.com/watch?v=RXhAj5BHdfM

Pumped-storage hydroelectricity is done in the alps (at least in Austria as well)
