Do solar lights always have to have direct sunlight or just daylight?

Solar lights do not require direct sunlight to function; they can operate effectively with daylight, even on cloudy or overcast days. While direct sunlight is optimal for charging the solar panels, ambient light can still provide some energy. However, the performance and brightness of solar lights may be reduced in low light conditions. For best results, placing solar lights in areas that receive ample sunlight during the day is recommended.
