How To Ground A Solar Panel System

Therefore one should drive multiple pipes deep into the ground surround them with rock salt and moisten the area.

How to ground a solar panel system.

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. The second fuse between your solar panels and charge controller is a little bit different to figure out. If the panels are connected in series the voltage of each panel is added but the amperage stays the same. There are two basic types of ground mounted solar panel systems.

Match the solar panel holes with the stand platform holes and screw them together. 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. At the back sides of the solar panel a small junction box is there with a positive and negative sign for polarity. Some standard ground mounted solar panel systems can be manually adjusted a few times a year to account for seasonal shifts of the sun.

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. The size of this fuse is dependent on how many solar panels you have and how they are connected series parallel or series parallel. Typically speaking ground mounted solar panels will cost around the same amount as rooftop solar panels when it comes to the price per watt. The electrical ground on the other hand can simply be made by connecting the grounded conductor to the earth or system ground.

Here s how we ground our solar water pump systems. Standard ground mounts use metal framing driven into the ground to hold your solar panels up at a fixed angle. For outdoor grounding you need to use thick bare copper wire that can. Drive a grounding rod at least 8 feet deep into the earth near the system.

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. Each grounding pipe should be around 8 feet deep but no less than 6 feet. 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. The national electrical code nec requires bonding electrically conductive materials and equipment to establish an effective ground fault current path.

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