Do you have any evidence for this position? Is this just regulations giving you bad vibes? I’m pretty sure everyone was quite aware the sun doesn’t shine at night whenever the previous rules and regulations were written. Your analysis isn’t breaking new ground.
As the amount of solar increases, the supply during the day goes up, so the daytime price starts going down. Meanwhile the highest demand period is just after sunset, so that's going to be when the price is highest because not only is that the highest demand, that's when solar generation is zero. And it's when people selling solar during the day are trying to buy power back. But now they're selling low and buying high.
And because they knew, the regulations I've heard of set some sort of statutory price that consumers get. This is because it's been fairly likely from the start that if the price is set by the market with reference to the value of the electricity, consumers won't get anything. Because their contribution is largely worthless and occasionally value-destructive.
I am A YIMBY too. But no, big money is not on your side. Big money wants to make money, not make your life better. It would like to build as much as possible for as little as possible, at the lowest quality possible, and sell it for an extremely high price. This isn't good for any of us.
Small money also wants to work as little as possible and sell it for an extremely high price. Selling maximal ROI is mostly a human thing. Also, there are “big money” developers building higher quality houses at higher prices, just like any other business.
Just take a look at ERCOT's website: https://www.ercot.com/gridmktinfo/dashboards/supplyanddemand
Peak demand is 6 PM when everyone gets home from work and turns on the air conditioning.
EDIT: Your chart shows the same thing? Demand is highest at 6 pm, not noon.
People regularly use the demand being supplied by solar to argue that solar isn't delivering when people need electricity.
The yearly peak grid demand in California is moving later in the day and later in the year due to this effect.
