6 FAQs about [What are the reasons for photovoltaic panel leakage ]

Why does the photovoltaic system generate leakage current?

Leakage current of the photovoltaic system, which is also known as the square matrix residual current, is essentially a kind of common mode current. The cause is that there is parasitic capacitance between the photovoltaic system and the earth.

How to eliminate leakage current in solar PV array system?

There are two distinct methods to eliminate the leakage current in the solar PV array system: (i) obstruct the leakage current, (ii) reduce the variation/constant common-mode voltage. The additional diodes/switches are incorporated in the system to obstruct the leakage current by disconnecting the PV array from the grid side network.

Can leakage currents occur at the edge of a PV module?

Therefore, the leakage currents occurring at the edge may be reduced. Fig. 3 Cross section of a thin-film PV module with a glass sheet as back cover and modelling of the possible leakage current pathways. The solar cells are negatively biased whereas the module frame is grounded. The arrow represents the direction of leakage currents.

Why does a solar PV system lose power?

In addition, the efficiency drop in a solar PV system is because of the effect of various kinds of faults and failures, which the system suffers. According to the test results conducted in 2010, the annual power loss in the solar PV system is about 18.9% due to its faults and failures .

What happens if a fault occurs in a solar PV system?

Reduced real time power generation and reduced life span of the solar PV system are the results if the fault in solar PV system is found undetected. Therefore, it is mandatory to identify and locate the type of fault occurring in a solar PV system.

What happens if a photovoltaic system is connected to a grid?

Hazard of leakage current If the leakage current in the photovoltaic system, including the DC part and the AC part, is connected to the grid, it can cause problems such as grid-connected current distortion and electromagnetic interference, so as to affect the operation of the equipment in the grid.
