No matter how many times you type it, it's still not true. The marginal cost when it's actually running is irrelevant, unless you plan to ignore your customers the 16 hours a day the solar is useless.
.
No matter how often you deny it, cost is cost. Utilization rate has nothing to do with it. Right now, today, utility size solar contracts deliver electricity to the grid at a cost $0.03 /KWH. Not for capacity, for actual product delivered. If you are familiar with the relative costs of generation, that’s half of the cost of natural gas, and a little less than half of coal. And close to a quarter of the cost of a gas peaker plant.
If you want to rely on solar, 50% of the cost can be in storage, and you’re still even.
