Clear-sky Modeling

The captest.clearsky module provides the pvlib-based clear-sky GHI/POA modeling used by load_data() when site metadata is supplied. This is distinct from clear-sky filtering, which is the Clearsky step (it calls pvlib.clearsky.detect_clearsky directly and does not depend on this module).

clearsky.csky(time_source[, loc, sys, ...])	Calculate clear sky poa and ghi.
clearsky.pvlib_location(loc)	Create a pvlib location object.
clearsky.pvlib_system(sys)	Create a pvlib PVSystem object.
clearsky.get_tz_index(time_source, loc)	Create DatetimeIndex with timezone aligned with location dictionary.
