What Size Solar Panel to Charge 12V Battery
Fast battery charging requires larger solar panels than slower charging. So if your goal is to charge a 100 Ah 12V battery in 4 peak sunlight hours, you would need bigger panels than charging it over 8 hours. Faster charging demands more solar wattage. Slower charging allows potential downsizing. Intended charging speed is key for solar sizing.

The panel will still charge the battery in partially cloudy weather, just slowly (provided there''s no load connected to the system using more power than the panel is able to generate). Obviously, at one point, the current able to be taken from the panel will be so negligible, that yea, you''ll stop being able to pull power from the panel at all.

Power ESP32/ESP8266 with Solar Panels and Battery
Most battery charger modules come with a resistor to set the charging current to either 500mA or 1A. This is much more than what a typical small solar panel can provide. If you get a small solar panel with 5V 1.5W, you will have at most 300mA. The resistor should be changed to adapt the charging current. See TP4056 datasheet for more details.
