Python wrapper for sun position algorithm written in c++ by Blanco-Muriel.

Project description

Python wrapper for sun position algorithm written in c++ by Blanco-Muriel. Accuracy 1 degree for the time interval from 1999 to 2015.

Blanco-Muriel M., Alarcon-Padilla D.C., Lopez-Mratalla D., and Lara-Coira M., “Computing the Solar Vector”, Solar Energy Vol. 70, No. 5, pp. 431-441, 2001.

To calculate sun position:
>>> import sunpos:
>>> print sunpos.__doc__

Sunpos package provides three structueres:

cTime:

whith fields:

iYear:year, integer
iMonth:month, integer
iDay:day, integer
dHours:double, UTC hours
dMinutes:double, minutes
dSeconds:double, seconds
cLocation:

with fields:

dLongitude:double, longitude
dLatitude:double, latitude
cSunCoordinates:

with fields:

dZenithAngle:double, zenith angle, degrees
dAzimuth:double, azimuth angle, degrees
>>> loc=sunpos.cLocation()
>>> loc.dLatitude = 43.1
>>> loc.dLongitude = 131.9
>>> time=sunpos.cTime()
>>> time.iYear = 2013 #imteger, year
>>> time.iMonth = 10 #Integer, month
>>> time.iDay = 13 #integer, day
>>> time.dHours = 16 #double, hours UTC
>>> time.dMinutes = 32 #double, minutes
>>> time.dSeconds = 12 #double, seconds
>>> #calculations
>>> res = sunpos.sunposf(time, loc)
>>> #or
>>> res = sunpos.cSunCoordinates()
>>> sunpos.sunpos(time, loc, res)
>>> print res.dZenithAngle # sun's zenith  angle
>>> print res.dAzimuth # sun's azimuth  angle:
>>>
