About Do photovoltaic bracket components need to be grounded
Eustace Soares referred to those parts of an electrical system that perform the grounding and bonding functions as “safety circuits,” which, in fact, they are. Without them, many electrical systems would fail. There is no requirement that a PV system be bonded at its disconnecting means but, if it is bonded there, the PV system grounded conductor is required to be connected to a grounding electrode system. Simply installing an equipment grounding conductor from the disconnecting means to the point of common coupling would create a parallel grounding .

In general, the grounding holes of the solar panel are used for connection between strings, and the solar panel grounding holes at both ends of the string are connected to the metal bracket. Another point, solar panel has an aging problem, and it may cause large leakage current or low Insulation resistance to ground.
The equipment in direct current (DC) portions of the PV system may be grounded using conductors as outlined above with appropriate connections to each metal surface. In general, when a copper wire is connected to a metal surface to be grounded, some sort of certified/listed grounding device must be used.
System grounding is your solar electrical wiring (inverter, etc). Equipment grounding is just the metal box, or the solar panels, or the rack itself (not electronics), even the combiner box case if its made of metal. Equipment grounding is more for lightning protection and not sure what else.
Theoretically, yes, you need to bond all exposed metal parts. Seems like there should be an exception for a 24V system but there isn't one. Only thing you might be able to go with is if these solar lights are a self contained product that come with instructions that don't mention grounding.

6 FAQs about [Do photovoltaic bracket components need to be grounded ]
What is electrical & PV grounding?
Before discussing the subject of grounding, the term “grounding” requires definition. There are two types of grounding in electrical and PV systems—equipment grounding and system grounding. Equipment grounding is known in the ROW as safety grounding or protective earthing.
Does a photovoltaic system have a DC grounding system?
Photovoltaic systems having dc circuits and ac circuits with no direct connection between the dc grounded conductor and ac grounded conductor shall have a dc grounding system. The dc grounding system shall be bonded to the ac grounding system by one of the methods in (1), (2), or (3).
Do PV systems need equipment grounding?
Regardless of system voltage, equipment grounding is required on all PV systems. Appropriate bonding and equipment grounding limits the voltage imposed on a system by lightning, line surges and unintentional contact with higher-voltage lines.
Why is proper grounding of a photovoltaic power system important?
Proper grounding of a photovoltaic (PV) power system is critical to ensuring the safety of the public during the installation’s decades-long life. Although all components of a PV system may not be fully functional for this period of time, the basic PV module can produce potentially dangerous currents and voltages for the life of the system.
Do I need a grounding electrode for a PV array?
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.
What are the bonding and grounding requirements for PV systems?
The specific bonding and grounding requirements for PV systems in Article 690 are in Part V. Section 690.41 covers system grounding, allowing both grounded and ungrounded PV array conductors.
