is_irradiated

Determines whether a surface at a given location and time is receiving solar irradiance.
Accounts for polar night/day conditions, sunrise/sunset times, and sun position below horizon.

A set of functions to calculate solar irradiance and insolation on Mars horizontal and inclined surfaces. Based on NASA Technical Memoranda 102299, 103623, 105216, 106321, and 106700, i.e. the canonical Mars solar radiation papers.
