If the frame is not grounded, a few years later, the inverter is likely to report corresponding failure, which will cause failure of normal power generation. 02：The solar panel bracket is grounded.
Grounded and ungrounded photovoltaic (PV) systems differ in design, implementation, and associated risks and benefits. Before comparing them, let’s explore each system in detail. What are Grounded Systems? These systems have a grounded conductor required by NEC Section 250-23(b) to run to each service.
To be clear, my expertise is in PV, not lightning, so I'm best at telling you what you're sacrificing if you don't bonding stuff together. In addition to maybe having a fault and a shock hazard on an AC line from a breaker not tripping, you might also have a PV ground fault which could cause a fire.
Owners of independent power systems do not have grounding supplied by the utility company, and often overlook it until it is too late. Some installations have reported damage to inverters, charge controllers, DC refrigerators, fluorescent light ballasts, TVs, pumps, and (rarely) photovoltaic panels.
As the photovoltaic (PV) industry continues to evolve, advancements in Is it OK if the photovoltaic bracket is not grounded have become critical to optimizing the utilization of renewable energy sources.

6 FAQs about [Is it OK if the photovoltaic bracket is not grounded ]
Can a solar PV system be grounded?
Solar PV systems are still permitted to be grounded, per 690.41 (A) (1) and (5), and, for those PV systems that are, the dc grounded conductor is directly coupled (or coupled through electronic circuitry) to the ac grounded conductor, which is then brought to ground potential by being terminated to the neutral bus bar at the main service panel.
What is the difference between grounded and ungrounded photovoltaic systems?
Grounded and ungrounded photovoltaic (PV) systems differ in design, implementation, and associated risks and benefits. Before comparing them, let’s explore each system in detail. What are Grounded Systems? These systems have a grounded conductor required by NEC Section 250-23 (b) to run to each service disconnecting means.
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).
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 ungrounded PV systems need ground protection?
In all cases, an ungrounded array must be provided with equivalent protection for ground faults, as required by NEC 690.35. A PV system is defined as a grounded system when one of the DC conductors (either positive or negative) is connected to the grounding system, which in turn is connected to the earth.
What is a grounded PV system?
A PV system is defined as a grounded system when one of the DC conductors (either positive or negative) is connected to the grounding system, which in turn is connected to the earth. The conductor that is grounded usually depends on the PV module technology.
