This page covers the layout and digging of the trench for the underground wiring from the meter/distribution panel location on the house to PV panel array out in the yard. The PV system we decided on uses Enphase micro-inverters mounted at each PV panel to convert the DC generated by the PV panel into grid compatible 240 volt AC.
Due to the amount of weight and surface area required at each leg and the space available, it is typical to link the front and back legs together with a single ballast block. Each block would need to be 8 ft. long x 1 ft. wide x 1.5 ft. deep. Helical Pile or Ground Screw:.
Drilled shaft piles for solar array footings can vary anywhere from 6 to 24 inches in diameter and 5 to 30 feet deep, depending on site conditions and other variables. The drilled shaft or borehole is filled with high-strength cement grout or concrete.
Low-voltage solar cables (e.g., 600V) are typically buried at a minimum depth of 18 inches (45 cm) to 24 inches (60 cm). Higher-voltage solar cables (e.g., 1,000V or above) may require a deeper burial depth, often between 24 inches (60 cm) and 36 inches (90 cm). Consult the local electrical code or consult with a qualified electrician to .

6 FAQs about [How deep should photovoltaic panels be piled underground ]
How deep is a drilled shaft pile for a solar array?
Drilled shaft piles for solar array footings can vary anywhere from 6 to 24 inches in diameter and 5 to 30 feet deep, depending on site conditions and other variables. The drilled shaft or borehole is filled with high-strength cement grout or concrete. At times, steel casing or re-bar is used for reinforcement.
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.
How far away should a grounding rod be from a solar panel?
Make sure the grounding rod is at least 10 feet away from any metal objects, such as fences or pipes. If you have more than one solar panel, you will need to install additional grounding rods 10-20 feet away from the first one.
What type of grounding does a solar inverter use?
A solar inverter uses system grounding. One of the two conductors coming out of the PV system is grounded, typically the negative wire. All system-grounded conductor wires must be white and are usually bonded to ground inside the inverter.
What is the difference between a ground-mounted and a double PV-based solar panel?
Given their inability to support large structures and ease of construction in relatively smaller spaces, we commonly refer to this type as residential ground-mounted solar panels. On the other hand, double PV-based solar panels use two pivots or axes to support the solar power system’s structure.
How do you ground a solar panel?
Drive a grounding rod into the ground near your solar panel array. The rod should be made of copper or galvanized steel and should be at least 8 feet long. Use a hammer to drive the rod into the ground until only 2-3 feet are sticking out. Make sure the grounding rod is at least 10 feet away from any metal objects, such as fences or pipes.
