Solar resource lookup
Solar irradiance by location.
Global horizontal (GHI), direct normal (DNI) and tilt-at-latitude irradiance by month, in kWh/m²/day. Satellite-model averages from NLR, not ground measurements; the dataset is named with every answer.
Type a city, a postal code, or coordinates such as 64.15 N, 21.94 W; then choose a match.
Note:
Enter a postal code. US sites use NLR Solar Resource Data; elsewhere, and where that dataset has no coverage, the PVWatts v8 typical year.
