The solution is obviously not exclusively from pricing models, we need other energy sources than renewables for the time being, that doesn't mean we need to have market-based electricity pricing.

Imagine the state installing as many solar panels as society, guided by experts, democratically decides it wants, basically deciding as a society the energy mix instead of hoping that companies will install enough if we bribe them enough with taxes to do so, and if it's profitable. Then, it decides a pricing model based on a mixture of subsidy and incentivising consumption during production hours.

Problem solved, innit?
