beam.diffuse(dat,plot=TRUE)
I0.blackbody(T.sun, wl.nm, plot = TRUE)
spectral(X, label, wl.lim.nm, T.sun, plot.surf = FALSE)
useful.waste(I0.bb)
sun.path(lat, nday, plot = TRUE)
sun.diagram(lat)
collector(Ibd, sunpath, tilt, azi.c, fr, label = "")
month.prod(dat)
tilt.adj(lat, days, labels)
one.axis.tracking(dat, mode = "PNS")
