Effect of Shading on Solar Plant Performance

Posted · Add Comment

Shading plays a very important role while designing the PV system layout. The field installation of solar array should be such that the modules are closest to southern orientation of the building/plane. All modules connected in a series string must be in same orientation, it is important that the distance between two array is kept […]
