Grounding Pv Solar Panels

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.

Grounding pv solar panels.

There are two types of ground. Regardless of system voltage equipment grounding is required on all pv systems. Solar installation the grounding portion of the system may well be the most important. Appropriate bonding and equipment grounding limits the voltage imposed on a system by lightning line surges and unintentional contact with higher voltage lines.

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. If lightning were to strike the solar panels outside the electric current may go into the panel grounding system if you are lucky or it may travel along the positive and negative wires going back to the inverter inside your house. 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.

Basically there are two types of grounding in a pv system equipment grounding and conductor grounding. For outdoor grounding you need to use thick bare copper wire that can handle large electrical currents like lightening. This is providing a path to ground for metal parts module frame mounting system etc that could be inadvertently energized by a faulted conductor. Third it can help prevent fires in the system post installation avoiding potential lawsuits from angry homeowners.

First it is required to ground all pv systems. Second a properly grounded system will help protect you and your employees from unintentional shocks and possible deaths. Safety v oltage transients and t h e sheer fact that they are required for some loads. 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.

Once there it could arc again to the house wiring. Equipment grounding is generally mandatory. Chassis or mechanical and electrical. Use a clamp to attach the copper wire to the grounding rod.

Pv mounting systems and devices. Drive a grounding rod at least 8 feet deep into the earth near the system. Of all the elements of a u s.
