il fait soleil

Hi Avi, 

You will hear,

'il fait (du) soleil' in France you can also say -

Il fait beau which often is seen as meaning that the sun is out

or 

Le soleil brille 

The word sunny is 'ensoleillé' but doesn't translate directly. You cannot say,

'il fait ensoleillé' 

You could say, 'c'est une belle journée ensoleillée'

Hope this helps!
