PVsol is a great tool !
The 3D modelling part (including the Google 3D terrain extracted by SketchUp) is great and user friendly (complete newbie speaking), the hardware library & description seems complete but the Senec 420M (bifacial) I needed to model is missing and I don't see a generic panel we could configurate. The number of parameters one can visualize about the photovoltaic system is huge. I only missed a measuring toolkit (distances, azimut or elevation, planar or solid angles,...) between objects in the 3D scene. I also would have liked to be able to compute the shading losses on a given time frame of the year, or for a given month (to be able for exemple to maximize the output of the generator during the winter).
