How To Ground A Solar Panel System

The soil tends to stay moist the deeper you go due to reduced evaporation.

How to ground a solar panel system.

Here s how we ground our solar water pump systems. The connection from chasis grounds to the earth or system ground should be done by copper wire and ground lugs with bonding wires or self tapping screws as required. The size of this fuse is dependent on how many solar panels you have and how they are connected series parallel or series parallel. The national electrical code nec requires bonding electrically conductive materials and equipment to establish an effective ground fault current path.

The electrical ground on the other hand can simply be made by connecting the grounded conductor to the earth or system ground. At the back sides of the solar panel a small junction box is there with a positive and negative sign for polarity. Therefore one should drive multiple pipes deep into the ground surround them with rock salt and moisten the area. In general bonding a piece of equipment means connecting it to an equipment grounding conductor egc that is bonded to the overall grounding electrode system.

Leave around 6 above ground to properly attach your copper wire to the grounding rod. Egc and gec grounding egc equipment grounding conductor is the green or bare copper wire that connects the racking hardware metal enclosures and emt conduit together. Wire the solar panel. Each grounding pipe should be around 8 feet deep but no less than 6 feet.

Match the solar panel holes with the stand platform holes and screw them together. The following sections of our solar panel installation guide outline grounding methods and some extra tips to help you ground your system properly. In a large size solar panel this junction box has terminal wires with mc4 connector but for small size panel you have to connect the junction box with external wires. There are two basic types of ground mounted solar panel systems.

For outdoor grounding you need to use thick bare copper wire that can. If the panels are connected in series the voltage of each panel is added but the amperage stays the same. While the rooftop solar panels are the most common choice for homeowners there are actually quite a few reasons you should take the time to consider a ground mounted solar panel system instead. The second fuse between your solar panels and charge controller is a little bit different to figure out.

Standard ground mounts use metal framing driven into the ground to hold your solar panels up at a fixed angle.
