If you're talking about the Add Photovoltaics user script in SketchUp mentioned in this post, then that already defines a constant efficiency to resemble PV panel type. The angle and azimuth of the PV panel matches the surface that you assign it to in SketchUp. This post has another option as an EnergyPlus measure. Are there other details you need?
