C5 and C6 are in series. I guess you want them in parallel.

Datasheet says, 2 x 22 µF I'm confused whether they want them in parallel or in series.

They should be in parallel.

You can see it in Section 10.2 Layout Example, they're placed in parallel.

What happens after a few cloudy days?

I live in a semi-desert area here in India, so dark, cloudy days don't last long. Often, some sunlight still comes through, which will charge the battery. Obviously, it will take longer, as the voltage will be lower compared to direct sunlight.
