Do solar panels work on cloudy days?

Yes, but at 10-25% of rated output. A 200W panel might produce 20-50W on an overcast day. Plan for extra charging time or bring a larger panel. CIGS panels perform slightly better in partial shade than monocrystalline.

Can I charge my phone directly from a solar panel?

Yes, if the panel has USB ports (like BigBlue 28W). Larger panels with Anderson connectors need a power station as an intermediary. Direct charging is slower — clouds cause interruptions that can confuse some phones.
