What happens on cloudy days, inclement weather or in geographically and seasonally challenged areas?
A- Solar lighting is dependent directly on UV (ultra violet) rays. UV rays exist in cloudy weather as well as in sunny conditions. However, the solar collector and battery capacity will absorb and perform best when exposed to direct sunlight. The simple answer is that light output (intensity) can be affected but unless there is no sunlight at all, the solar charge will be active.
