Advantages & Disadvantages of Ground-mounted Solar Panels
Ground-mounted solar panels, as the name implies, are a free-standing solar array mounted on the ground, either atop one pole or on a sturdy metal frame. Because they are
All the equipment in the outdoor substations is within view, and therefore fault location is easier. The expansion of the installation is easier in the outdoor substations. The time requires in the construction of such substations is lesser. The smaller amount of building material like steel, concrete is required.
Disadvantages On the other hand, an ungrounded system makes it difficult to find line-to-line ground faults, and additional labor to find these ground faults will result in higher cost of maintenance.
The following are some critical advantages of ground-mounted panels: Ground-mounted solar panels outperform rooftop PV cells in terms of power per square foot. Ground-mounted systems deliver power at around a 22% efficiency ratio to rooftop solar panels, which deliver power at around 18-19% efficiency.
The biggest disadvantage of a solidly grounded system is that it can cause extremely high value fault currents when used in high voltage distribution systems and possibly result in equipment damage. Because of this danger, solidly grounded systems are used in low voltage systems.
