Grounding Pv Solar Panels

Once there it could arc again to the house wiring.

Grounding pv solar panels.

Pv mounting systems and devices. First it is required to ground all pv systems. Regardless of system voltage equipment grounding is required on all pv systems. Metal mounting structures other than building steel used for grounding purposes should be identified as equipment grounding conductors or have identified bonding jumpers or devices connected between the separate metal sections bonded to the grounding system.

Basically there are two types of grounding in a pv system equipment grounding and conductor grounding. 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. For outdoor grounding you need to use thick bare copper wire that can handle large electrical currents like lightening. Second a properly grounded system will help protect you and your employees from unintentional shocks and possible deaths.

Third it can help prevent fires in the system post installation avoiding potential lawsuits from angry homeowners. Use a clamp to attach the copper wire to the grounding rod. There are two types of ground. Appropriate bonding and equipment grounding limits the voltage imposed on a system by lightning line surges and unintentional contact with higher voltage lines.

Of all the elements of a u s. But before we address each of these it s important to understand the actual definition of ground. Equipment grounding is generally mandatory. You also have two thick copper wires negative and positive going from your inverter to your solar panel array outside that also has its own grounding system but is not bonded with the house grounding system.

Solar installation the grounding portion of the system may well be the most 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. Drive a grounding rod at least 8 feet deep into the earth near the system. There are three main reasons for grounding in an off grid power system.

Leave around 6 above ground to properly attach your copper wire to the grounding rod. Safety v oltage transients and t h e sheer fact that they are required for some loads. This is providing a path to ground for metal parts module frame mounting system etc that could be inadvertently energized by a faulted conductor.
