Calculation of incident Solar Flux

[kumudini1]

Hi,

Does the surface variable in vista "Incident Solar Flux" includes all three components;
1) direct solar radiation
2) diffuse solar radiation
3) reflected radiation from adjacent buildings

Or it only gives the direct and diffuse radiation?

Please assist to clarify.

Thanks

Incident Solar Flux is the sum of the (beam) direct radiation, the (horizontal) diffuse radiation and radiation reflected from the ground.

I hope this helps.
