It is not so much the shadows being cast as the amount of sun and ambient light and the % of sun included in the ambient light as Erich mentioned.
Also the material (or I should now say Surface) settings will have an impact.
For example here is the same material but with different Reflection > Ambient settings.
Other settings in the materials may also have an effect as well.
