HOME / Does the photovoltaic bracket need to be grounded separately - CAPTURED ENERGY SOLAR (PTY) LTDConnection to the Grounding System The entire PV installation should be connected to an external grounding system or the building's internal grounding network. It is essential to use conductors of appropriate cross-section, in compliance with regulatory requirements.
Photovoltaic panels allow for the efficient use of solar energy and significantly reduce electricity bills. However, for the entire installation to operate safely and efficiently, proper grounding of the photovoltaic system is crucial.
While a separate grounding electrode system is still permitted to be installed for a PV array, per 690.47 (B), it is no longer required to be bonded to the premises grounding electrode system. In PV systems with string inverters, the equipment grounding conductor from the array terminates to the inverter's grounding bus bar.
However, some contractors, who had been accustomed to grounding the system at the inverter, still prefer to install a grounding electrode conductor at that point. While this is permitted, per 690.47 (B), it is done only for grounding the PV equipment and not for grounding the PV system.
A comprehensive guide to the grounding and bonding requirements for solar PV arrays and equipment as outlined in NEC Article 690, Part V.
A solidly grounded PV array, as permitted, in 690.41 (B), as permitted, per 690.41 (A) (5), is a special case where the PV array contains no more than two source circuits, i.e., two strings of
