Weather
The hourly or sub-hourly series the simulation runs on
What it is
The weather section carries the time series the simulation runs on: global and diffuse horizontal irradiance, direct normal irradiance, ambient temperature and wind speed, plus optional pressure, relative humidity and precipitable water. Timestamps mark the start of each interval, at the fixed UTC offset given by the time zone. The Lee and Panchula spectral correction needs either a precipitable water column or a relative humidity column; without one of them it cannot run.
Typical values and how to get it
Upload a file. The parser recognises NSRDB, PVGIS, TMY3, PVsyst CSV and generic CSV layouts, fills missing columns where it can and lists what it filled. A typical meteorological year gives a long-term average result; a measured year gives that year.
