> In sane markets like Finland solar panel owners need to pay for generating electricity to the grid if the price is negative

If this were the case, why would solar panel owners not stop "selling" power to the grid at their expense when that happens? What incentive would ever exist to pay to put power on the grid?

I think the point is to encourage people to have a way to stop exporting when there is not the demand by passing on the negative price that all generators would see in that situation.

Apparently not generating power will cause the panel to slightly overheat which will add additional tear on the panel, so it might make sense to pay the negative prices instead.

Note that electricity generated will first be used by the consumer and only excess is sold to the grid.
