How does the Solar Irradiance Calculator work?

Direct normal irradiance (DNI): beam radiation perpendicular to surface Then: Diffuse horizontal irradiance (DHI): scattered radiation from entire sky Then: Global horizontal irradiance (GHI): total arriving at horizontal surface.

Can you give an example of how to use the Solar Irradiance Calculator?

Example: Input Clear day, sea level, solar noon gives a result of GHI ≈ 1000 W/m² (AM 1.5 standard spectrum) (Peak theoretical).

Is the Solar Irradiance Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.
