A novel technique to obtain the health of a PV panel

Power efficiency delivered from a PV panel individually or as larger system for example a PV Solar Form is very much dependent upon many factors for example irradiance, temperature, shadowing and the health of individual PV panels/cells. The first two factors are typically beyond the control of designer/engineers but certainly if we can determine shading and early diagnoses about the health of a panel/cell we can quickly fix such issues so that system delivers normal power production for which it is designed and maintains the required power efficiency.
