Model_Chains pv_nameplate error #132
Description
Error results when passing in 'pv_nameplate' input into SystemAnalysis object.
minimum example:
sa = rdtools.SystemAnalysis(df['power_E'], df['poa'],
cell_temperature=df['Tcell'],
pvlib_location=loc,
pv_tilt=meta['tilt'],
pv_azimuth=meta['azimuth'],
pv_nameplate = meta['pdc']
)#
Error:

UnboundLocalError: local variable 'pv_nameplate' referenced before assignment
Solution: has to do with pv_nameplate and self.pv_nameplate naming error. Will submit pull request momentarily.
