0.1.8.1 bug fix

Error in setup.py resulted in incorrect loading of packages.

v0.1.8 Release

See What's new for details on release.

Python3 compliance and pytests

This version is now Py3 compliant, and integrates with TravisCI with pytests.

EPW file input capability

Bug fixes:

• 'first' and 'last' single axis tracking no longer causes errors
• 'ARglass' option for front or back glass input provides feedback if text input is incorrect
  New functionality:
• EPW files can be imported for meteorological data
• Updated single axis tracking example in notebook
• streamlined code by removing Cv and offset inputs in simulate()

Python 3.6 compatibility

Print and other statements are updated to enable Python 3.6 compatibility.
This version will be made available on PyPi to allow quick command line installation: pip install bifacialvf.

Update calculations for southern latitudes

Small bug fix when using rowSpacing() function to determine the minimum row spacing of systems - for southern latitudes, it was not correctly using the winter solstice (June Solstice) and instead was using the December solstice for the row spacing calculation.

Tracker limit angle update

Minor revision to allow adjustment of tracker rotation limit

Single axis tracking update

Several errors were discovered in the SAT algorithm that have been addressed here.
SAT ground clearance is now set by C = hub height (clearance at tilt = 0). This value must be > 0.5 to avoid errors
Row spacing may be set with either D (gap space between modules) or rtr (row to row spacing).
