The NFPA and IEEE recommend a ground resistance value of 5 ohms or less while the NEC has stated to “Make sure that system impedance to ground is less than 5 ohms specified in NEC 50.56. In facilities with sensitive equipment it should be 5ohms or less.
A PV array section with hundreds of grounding paths—as with a fully bonded array—versus a single copper wire has much less resistance to earth. Recent field testing performed on a UL 2703 array showed that the UL 2703 method had much lower ground path resistance than the same array using a bare copper EGC.
For the resistance of a PV module an average value can be assumed: for thin-film PV modules approximately 40 MOhm and for polycrystalline and monocrystalline PV modules approximately 50 MOhm per PV module (for further information on calculating the insulation resistance see the Technical Information "Insulation Resistance (Riso) of Non .

6 FAQs about [How much is the grounding resistance of the photovoltaic panel in ohms ]
What ohm is a good ground resistance?
The telecommunications industry has often used 5 ohms or less as their value for grounding and bonding while electric utilities construct their ground systems so that the resistance at a large station will be no more than a few tenths of one ohm. In general, the lower the ground resistance, the safer the system is considered to be.
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.
How many ohms should a grounding system be?
In facilities with sensitive equipment it should be 5ohms or less. The telecommunications industry has often used 5 ohms or less as their value for grounding and bonding while electric utilities construct their ground systems so that the resistance at a large station will be no more than a few tenths of one ohm.
What ohms should a ground resistance test be?
The NFPA and IEEE recommend a ground resistance value of 5 ohms or less. Computers, generating stations, and process control equipment may require as little as 1 or 2 ohms. 4. What affect does rain have on a ground resistance test?
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).
What is a good ground resistance value?
The NFPA and IEEE recommend a ground resistance value of 5 ohms or less while the NEC has stated to “ Make sure that system impedance to ground is less than 5 ohms specified in NEC 50.56. In facilities with sensitive equipment it should be 5ohms or less.
