solarforecastarbiter.pvmodel¶
Calculate AC power and modeling intermediates from system metadata, times, and weather data.
Steps are:
- Calculate solar position using solar_position
- If not already known, calculate 3 irradiance components from measured GHI using irradiance_components or modeled clear sky using clearsky.
- calculate_poa_effective
- calculate_power
Steps 3 and 4 are bundled in irradiance_to_power()
