A problem trying to connect sunlight to 3 kinetic facades

We created a parametric kinetic facade that varies according to the sun. When it’s one facade it works. But when we added two more facades, they changed changed in the same pattern. how do we create a parametric building facades that change according to sunlight? (we use SolarArc plugin)
