Solar Earthing & Lightning Protection Accessories
Engineered to IS 3043 & IS/IEC 62305.
DFMHUB manufactures and supplies ARK Make certified solar earthing and external lightning protection hardware for utility-scale solar farms, industrial rooftop PV arrays, and floating solar installations across India.
Why Coordinated Earthing & Lightning Protection Matter in Solar Plants
Utility-scale solar farms, industrial rooftop installations, and floating PV arrays encompass thousands of conductive module frames, high-voltage DC string cables, inverters, and sensitive SCADA networks spread over wide, exposed terrain.
Step & Touch Potential Protection for Field Personnel
In multi-megawatt solar plants, ground fault currents create dangerous localized potential gradients. An engineered equipotential grid dissipates fault energy safely to prevent shock hazards for O&M teams.
Galvanic Corrosion & Positive Contact Integrity
Combining aluminium module frames with galvanized or copper grounding without certified bimetallic clamps triggers electrochemical corrosion, resulting in high-resistance hotspots and fire risks.
Direct Strike & Electromagnetic Pulse (LEMP) Defense
A lightning strike to an unshielded PV table propagates destructive transient surges down DC cables into central inverters and tracker electronics. Coordinated air-terminals and SPDs eliminate catastrophic downtime.
ARK Make BOS clamps & conductors installed across multi-megawatt solar plants.
There is no single universal earthing layout suitable for every solar project. DFMHUB reviews your plant layout, soil resistivity, DC string architecture, and structural geometry to provide an exact, standards-compliant BOQ.
