Grounding Pv Solar Panels

Equipment grounding is generally mandatory.

Grounding pv solar panels.

But before we address each of these it s important to understand the actual definition of ground. 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. Third it can help prevent fires in the system post installation avoiding potential lawsuits from angry homeowners. This is providing a path to ground for metal parts module frame mounting system etc that could be inadvertently energized by a faulted conductor.

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. There are two types of ground. Once there it could arc again to the house wiring. Regardless of system voltage equipment grounding is required on all pv systems.

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

Pv mounting systems and devices. First it is required to ground all pv systems. Use a clamp to attach the copper wire to the grounding rod. 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.

Leave around 6 above ground to properly attach your copper wire to the grounding rod. There are three main reasons for grounding in an off grid power system. 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. Solar installation the grounding portion of the system may well be the most important.

Basically there are two types of grounding in a pv system equipment grounding and conductor grounding. Appropriate bonding and equipment grounding limits the voltage imposed on a system by lightning line surges and unintentional contact with higher voltage lines. Chassis or mechanical and electrical.
