Through this article, we will show you how you can ground step by step your solar panel correctly. We will also provide a few extra tips and the most frequently asked questions to help you get the most out of your ground solar power system.
In this guide, we’ll walk you through the ins and outs of solar panel grounding, covering everything from basic concepts to step-by-step instructions. The most important takeaway? Always use #6 AWG bare copper wire for outdoor grounding to meet National Electric Code requirements and pass inspections.
System grounding is your solar electrical wiring (inverter, etc). Equipment grounding is just the metal box, or the solar panels, or the rack itself (not electronics), even the combiner box case if its made of metal. Equipment grounding is more for lightning protection and not sure what else.
1) Ground fault current always needs an effective return path back to the source. An equipment grounding conductor (EGC) provides such a path in most of the cases. In this regard, a main bonding jumper (MBJ) should be installed to connect the EGC to the neutral of the supply at one point only (see figure below).

6 FAQs about [What to do if the photovoltaic panel is grounded]
Should I ground my solar panel system?
By considering these additional factors, you can ensure your grounding system is tailored to your specific needs and maintains its effectiveness over time. Properly grounding your solar panel system is a critical step that should never be overlooked or rushed.
Where can I find information about solar panel grounding?
Your local electric utility company or a qualified electrician can provide you with more information about solar panel grounding. Now that you know how to install, maintain, and troubleshoot ground solar panels, you can start saving money on your energy bills.
Do solar PV systems need to be grounded?
Key points from the NEC: The code requires all non-current-carrying metal parts of the solar PV system to be grounded. It specifies the minimum size of grounding conductors (more on this later). The NEC also outlines requirements for grounding electrodes (like ground rods) and how they should be installed.
Why do solar panels need grounding?
Electrical safety is of paramount importance when it comes to solar panel installations. Grounding plays a significant role in ensuring the overall safety of the system. By providing a path for fault currents to flow harmlessly into the ground, grounding helps prevent electrical shocks and reduces the risk of fire hazards.
How do you ground a Photovoltaic (PV) system?
To ground a Photovoltaic (PV) system, connect a copper conductor to the steel bonding or metal pole and conduct it to the ground. This is known as equipment grounding. It is essential for safety reasons, as no one wants to be electrocuted. The second type of grounding is called system grounding.
What is a ground solar panel?
A ground solar panel offers easier control over your solar panel’s position and orientation. The solar panel faces either south or southeast for maximum sunlight. You may set a solar panel in any direction you wish to increase sun protection, unlike curved roofs.
