How to Wire Solar Panels Before we get into the nitty-gritty of solar panel wiring, there are a few basic terms and considerations that you should know. Important electrical terms 1 – Voltage …
Metal parts of PV module frames, PV equipment, and enclosures containing PV system ac and dc conductors must be connected to the circuit equipment grounding conductor per 690.43 (A) through (D). (A) Photovoltaic Module Mounting Systems and Devices.
A building or structure supporting a PV system must have a grounding electrode system installed [690.47 (A)]. PV systems are grounded when the PV inverter output ac circuit equipment grounding conductor terminates to the distribution equipment grounding conductor terminal [690.47 (A) (1).
Understanding Solar Panel Grounding Diagrams. Grounding is a crucial aspect of any solar panel installation. It ensures the safety of the system and the people who work on and around it. …

Since the PV array and other electrical equipment in PV system, e.g., inverters, are often located remotely from one another, 690.43 (B) requires that an equipment grounding conductor (EGC) be run from the array to other associated equipment.
7. Open any exposed junction boxes, check for grounding lugs, ground wire and secure wire connections. 8. Check modules grounding to supporting rails. 9. Modules grounding wires and …
Where no overcurrent protective device is required [690.9 (A) (1)], the equipment grounding conductor for the PV system dc circuit must be sized per Table 250.122 based on an assumed overcurrent protective device for the circuit sized per 690.9 (B).
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.
This is why Article 690.31(C)(2) requires securement at intervals no larger than 4.5 feet for USE-2 and PV Wire. The support requirements for cable tray are more stringent in 690.31(C)(2) than 334.30. One reason for the …
