Solar Geometry: Calculated using standard solar position algorithms (declination, hour angle, zenith)
Clear-Sky Model: Based on air mass corrections and typical atmospheric transmittance
Reference Data: Calibrated against PVGIS (Photovoltaic Geographical Information System) — EC JRC
Solar Constant: 1361 W/m² (extraterrestrial irradiance)
Note: Values represent typical clear-sky conditions. Actual values vary with cloud cover, altitude, aerosols, and local atmospheric conditions.
