This can be attenuated with variable pricing, like in France[1] which has 80% on nuclear—which doesn't ramp up/down very fast. One could call that free-market pricing: more expensive power during high demand, cheaper when supply is high. Industries and homes find innovative ways to adapt to market pricing. All the appliances there have options to use power at night (when it is cheaper there). For solar, the times may be different but the same idea remains. Commercial power is priced at a premium when the grid is overloaded (typically winter months).
