6 FAQs about [Abnormal voltage of solar power generation]

Are faults a problem in solar PV systems?

PV faults in solar PV array results significant power loss, lower reliability, very fast panel degradation, and further risk of fire (Gokmen et al. 2013 ). This chapter presents a comprehensive literature review along with a critical analysis of fault diagnosis and condition monitoring for solar PV systems. Major contributions are:

What are faults & defects in solar PV array?

Faults, defects, and shading conditions in PV array involve detection as a prime computational task. PV faults in solar PV array results significant power loss, lower reliability, very fast panel degradation, and further risk of fire (Gokmen et al. 2013 ).

What causes a solar panel to fail?

The surge due to lightning can be one of the causes for this fault. If any fault occurs in this diode or it gets short-circuited, then it reduces the efficiency of the solar panels or in some cases leads to circulating current which can damage the solar array.

Why do solar PV modules fail?

Faults can occur in the solar PV modules in several ways like extrinsic, i.e., defect created during manufacturing, failure occurring during the design, fabrication, or assembly process (Karmacharya and Gokaraju 2017; Harrou et al. 2019 ).

How to detect faults in PV array system?

Environment pollution and physical defect-based detection are equally important for the overall fault detection of PV array system. Further pollution detection techniques are suggested by authors for fault detection as given in Table 3.3. The values of current and voltages are gathered through sensors already mounted on PV modules.

What are the three static techniques used in a solar photovoltaic generator?

Provided by the Springer Nature SharedIt content-sharing initiative Three static techniques (i.e. Power flow, Continuation Power Flow (CPF) and the Q–V curve) are used to assess the voltage stability of the power grid with a Solar Photovoltaic Generator (SPVG) and FACTS devices under nominal and heavy loading conditions.
