Pakistan Micro-module Grounding
In most areas of Pakistan, a depth of up to 70–80 feet is required to get less than 5 Ohms of earth resistance — the safe benchmark recommended by international electrical safety codes. Since 2016, Electrosoft Technologies has completed over 2000+ projects in earthing and lightning protection. Imagine relying on solar power while safeguarding your home from unpredictable Pakistani storms and power surges. As Pakistan grapples with energy challenges, solar energy becomes more vital. However, a critical safety issue is being ignored by far too many installers: inadequate or shallow earthing systems. A substation that loses a transformer to a direct lightning strike in Sindh costs more than its replacement value — it costs weeks of. At GSE Solar (Glowsun Engineering Pvt Ltd), we take solar safety seriously. We specialize in advanced chemical earthing systems in Pakistan.
