Abstract
This paper addresses a developed viable fault-detection scheme based on power evaluation and observation against partial shading degradation faults in solar photovoltaic (PV) system. To extract maximum power from photovoltaic systems and increase their efficiency and performance under atmospheric circumstances changes that leads to PV system failures, like solar irradiance and ambient temperature. An explicit fault detection algorithm is derived to detect the effectiveness factor as well as the threshold indicator relating the partial shading faults in PV array. Simulation result on PV array is demonstrated to justify the validation of the proposed design scheme. The faulty part of the array is detected with a short and acceptable time period and a computation load reduction for large number of PV modules
