> What do you do during a windless cloudy day or (any) night? No solar, no wind, no nothing. Small clouds, large power fluctuations, and you get grid failures.

Even when it's cloudy there's still light, it's not as if it's pitch black when there's clouds, what do you think is illuminating everything still?

But efficiency in solar panels needs to increase, which is happening.
