Depends on the cloud. Where I live I routinely get 50% generation on a "cloudy" day.
On a rainy day that drops closer to 20%.
As an aside - cloudy days avoid a problem I have with shade. In winter, at 3:30pm, the sun goes behind a tree and my production plummets to near zero. If there's cloud cover the sunlight is far more dispersed and there's no "shade".

No, 20% is not sufficient to power the home. I'm still attached to the grid and use grid power even solar is too low.
And you’re still able to power your entire home? What if the rain lasts for a few days, which is pretty common in many places.
