What is Earthing?
Earthing (or grounding) is the process of connecting parts of an electrical system to the earth. This creates a path for fault current to safely discharge into the ground, protecting equipment and people.
Why Earthing is Important for Solar Panels
Here are the top reasons why earthing for solar panels is essential:
-
Electrical Safety: In case of a short circuit or lightning strike, earthing protects users and equipment.
-
System Protection: Prevents damage to inverters, panels, and connected appliances.
-
Lightning Protection: Minimizes the risk of electrical surges during storms.
-
Compliance: Meets BIS, IEC, and other national/international safety standards.
-
Improved Efficiency: Reduces electrical noise and voltage fluctuations, enhancing system performance.
Types of Earthing Systems for Solar Installations
Solar installations can use different types of earthing, depending on the size and location of the system:
-
TN-S or TN-C Systems (common in grid-connected setups)
-
TT Systems (popular in rural areas)
-
IT Systems (used in isolated or sensitive applications)
A professional assessment will determine the most suitable system.
Key Components of Solar Earthing
A good solar earthing system typically includes:
-
Copper-bonded earthing electrodes
-
GI or copper earthing strips
-
Backfill compound (BFC) for reducing soil resistance
-
Test links and inspection chambers
-
Lightning arrestors (for full protection)
