peak solar irradiation displayed on surface

Hello,

Does anyone know if there is a relatively quick way to calculate and display the peak solar irradiation on each surface (by grid cell) using Ladybug (similar to how Ecotect quickly displays the peak, ecotect.jpg)? I'd like to be able to do this to assess solar shading needs at concept / schematic design level without a very long computational time. Currently, I'm only aware of a way to calculate the annual cumulative solar irradiation quickly. This question is similar to the one asked in this thread: http://www.grasshopper3d.com/forum/topics/peak-annual-values?groupU... 

Perhaps there is already a component that does this, but I am relatively new to GH/Ladybug and would like to make sure I'm not reinventing the wheel.

Thanks,

Irene
