Two mistakes in this:

1. Comparing nameplate capacity of solar to peak demand. The real peak production figure is about half of that. Which changes the equation from "we have far too much already" to "we don't have enough yet". And we should be targeting higher than the peak anyway.

2. Noting that midday demand has dropped and not connecting that to rollout of behind the meter solar on domestic and business roofs.

Plus the general scaremongering about negative prices. Why do people find these so scary?

"The market floor price can fall as low as -€500/MWh. Yes, you read that correctly, bids can be submitted with negative prices. Subsidized renewables and must-run assets (such as nuclear) usually bid at that price to ensure their production.

What is incredible is that in the last five years, around 11 GW of additional capacity has been added that bids at negative prices during the day."

Which means they should pay electric car owners for absorbing that energy.
