Bonding is closely related to grounding and involves connecting all metal parts of the solar energy system together to ensure they are at the same electrical potential.
What is the process of grounding and bonding a solar PV array?
The National Electrical Code (NEC) requires bonding electrically conductive materials and equipment to establish an effective ground-fault current path.
Why do solar panels need bonding?
Bonding prevents a host of possible risks and dangers. “Imagine: the insulation on a PV source circuit wire becomes damaged, and the current-carrying part of the conductor makes contact with a frame or rail,” said Brian Mehalic, PV Curriculum Developer and Instructor at Solar Energy International.
How do solar panels work?
Solar panels convert sunlight into electricity. This process involves converting the Direct Current (DC) generated by the solar panels into Alternating Current (AC) using an inverter. The inverter is then connected to an electrical meter, which measures the electricity generated by the solar panel system.
Why is a PV system bonded?
“Bonding and grounding PV systems ensures public safety, as well as the safety of PV installers and field electricians,” said Andy Zwit, Codes and Standards Manager at ILSCO. Excluding modules, the majority of components in PV systems are bonded like any other electrical system.
Excluding modules, the majority of components in PV systems are bonded like any other electrical system. For example, grounding busbars are connected to the metal chassis of enclosures, such as disconnect switches, combiner boxes and inverters, and then an equipment grounding conductor (EGC) is connected to the busbar, Mehalic explained.
How do solar panels convert solar energy into electricity?
A solar panel is a device that converts solar energy into electricity. When sunlight (photons) hits the solar panels, the light energy gets converted into electricity. The generated electricity can be used for powering various home appliances.
