I have done simulations like these by using option B, but with one extra setting in the idf:
Just set an Output:Diagnostics object as 'DoNotMirrorDetachedShading'. That way the shading of your shading devices will only occur in the direction of the surface normal (which obviously should point in the direction of the window), so the walls behind them won't be affected. The darker purple color represent the side of the surface which the normal points to, which means the shading surfaces in your image are oriented the wrong way.
If you are using OpenStudio, you can use the 'AddOutputDiagnostics' Measure from BCL and select the 'DoNotMirrorDetachedShading' option.
