The photovoltaic panel has no grounding hole

For the solar panel grounding, general use 40 * 4mm flat steel or φ10 or φ12 round steel, and finally buried depth of 1.5m underground, the grounding resistance of the PV module is not less than 4Ω, for those who do not meet the grounding resistance requirements, usually use the addition of anti-drag agent or select the soil where the low .

Properly grounding your solar panel system is a critical step that should never be overlooked or rushed. It’s not just about meeting code requirements – it’s about ensuring the safety of your home and the longevity of your solar investment.

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 .

Grounding and bonding is a subject area that can be confusing to many. In this blog post, we summarize key points according to the NEC. The NEC is the primary guiding document for the safe designing and installation practices of solar PV systems in the residential and commercial markets in the United States.

6 FAQs about [The photovoltaic panel has no grounding hole]

Should I ground my solar panel system?

By considering these additional factors, you can ensure your grounding system is tailored to your specific needs and maintains its effectiveness over time. Properly grounding your solar panel system is a critical step that should never be overlooked or rushed.

How do you ground a Photovoltaic (PV) system?

To ground a Photovoltaic (PV) system, connect a copper conductor to the steel bonding or metal pole and conduct it to the ground. This is known as equipment grounding. It is essential for safety reasons, as no one wants to be electrocuted. The second type of grounding is called system grounding.

Do solar panels need a grounding conductor?

The Grounding conductor of the PV array must be bonded with the building equipment ground. In addition, it is permitted to have additional grounding electrodes tied directly to the PV Grounding Conductor. Traditional: Daisy Chained Copper Wire between components. Grounding solar panel frames and mounts – Traditional Daisy Chain.

What kind of grounding do solar installers use?

Most solar installers are familiar with equipment grounding (EG), which is the more traditional and visible form of grounding, says C.J. Colavito, commercial engineering manager and North American Board of Certified Energy Practitioners (NABCEP) certified solar PV installer for Rockville, Md.-based Standard Solar.

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.

How do you ground a solar panel?

The traditional method for tying ground to the Solar Panel Frames and mounts is to daisy chain a grounding conductor connecting all of the metal components. An approved Grounding lug that is designed to press through the Anodized layer is used on each component. These lugs use stainless steel grub screws to prevent galvanic corrosion.
