Grounding Pv Solar Panels
Chassis or mechanical and electrical.
Grounding pv solar panels. Use a clamp to attach the copper wire to the grounding rod. Basically there are two types of grounding in a pv system equipment grounding and conductor grounding. This is providing a path to ground for metal parts module frame mounting system etc that could be inadvertently energized by a faulted conductor. Safety v oltage transients and t h e sheer fact that they are required for some loads.
Devices and systems used for mounting pv modules that are also used to provide grounding of the module frames should be identified for the purpose of grounding solar panels. For outdoor grounding you need to use thick bare copper wire that can handle large electrical currents like lightening. First it is required to ground all pv systems. Of all the elements of a u s.
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. 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. 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. There are three main reasons for grounding in an off grid power system.
Appropriate bonding and equipment grounding limits the voltage imposed on a system by lightning line surges and unintentional contact with higher voltage lines. Once there it could arc again to the house wiring. Solar installation the grounding portion of the system may well be the most important. Equipment grounding is generally mandatory.
Leave around 6 above ground to properly attach your copper wire to the grounding rod. Drive a grounding rod at least 8 feet deep into the earth near the system. Third it can help prevent fires in the system post installation avoiding potential lawsuits from angry homeowners. Proper grounding of a photovoltaic pv power system is critical to ensuring the safety of the public during the installation s decades long life.
There are two types of ground. Regardless of system voltage equipment grounding is required on all pv systems. Pv mounting systems and devices.
