PyEphem is, comparatively, a much more sophisticated and full-blown astronomical engine daylight, on the other hand, is focused on much smaller subset of problems

pvlib-python

GitHub: https://github.com/pvlib/pvlib-python

Aimed at photovoltaic energy system development, it includes many things which you might not need, so if your use cases is to just compute brightness levels of the day - it could be an overkill

Additionally, it is written in pure python, compared to daylight which benifits from the portability and efficiency of a C++ based implementation

• Can calculate for any orientation of surface plane

• Seems to only consider latitude when computing irradiance levels

• Written in pure python
