When maxSolardRad has to be calculated with the Bras method one has to add
to weewx.conf:
[StdWXCalculate]
nfac = 2 # for solar radiation Bras
[[Algorithms]]
maxSolarRad = Bras # RS or Bras
Because parameter nfac is not read/initialized weewx crashes with error:

# atmospheric turbidity (2=clear, 4-5=smoggy)
self.nfac = float(svc_dict.get('nfac', 2))
