6 FAQs about [Photovoltaic panel leakage performance diagram]

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.

What is the leakage current at VDC /2?

As common-mode voltage is fixed at VDC /2, the leakage current is attained within 82 mA, which is lower than recommended by the VDE-00126 standard. However, the grid currents are highly distorted at the load unbalancing scenario as exhibited in Fig. 10b.
