Solar Irradiance Data: Phoenix
10 to 12
Monthly average solar irradiance for 23 representative global locations — GHI, DNI, DHI, tilt irradiance, peak sun hours, clearness index, and temperature. TMY-style reference data for PV system design and solar energy analysis. Each location has 12 monthly records (month=1-12) plus one annual summary row (month=0).
