There always a grid cost and solar energy is always cheapest when there is more solar power. Additionally users of electricity largely want fixed prices not wholesale prices.

So how do you expect people putting solar on their houses to pay fair share of, low energy value, grid costs, inertia and frequency control, higher prices at peak?

I’m all for solar but there is no way solar producers should get prices at peak time when they producing at off peak time with high supply and getting free additional costs.
