Unicorn Energy Systems is a Lahore-based electrical engineering company specializing in earthing solutions and solar PV (photovoltaic) systems. The company designs and installs complete earthing systems, lightning protection, and solar power solutions for residential, commercial, and industrial clients across Pakistan.

Yes. Unicorn Energy Systems is recognized as Pakistan’s first manufacturer of earthing chemicals, producing locally formulated compounds used to achieve low-resistance, long-lasting earth pits suitable for Pakistan’s varying soil conditions.

The company is based in Lahore and serves clients throughout Punjab and other regions of Pakistan, covering both residential earthing/solar installations and larger commercial and industrial projects.

An earthing (grounding) system provides a safe, low-resistance path for fault currents, surges, and lightning strikes to dissipate safely into the ground. Without proper earthing, electrical faults and surges can travel through walls, wiring, and appliances, causing equipment damage, fire hazards, and risk to human life.

Earthing chemicals are conductive compounds applied around an earth electrode (earth rod or plate) to reduce soil resistivity. They help maintain low earth resistance even during dry seasons, extend the life of the earth pit, and reduce the need for frequent maintenance compared to traditional charcoal-and-salt earthing methods.

Traditional charcoal-and-salt earthing degrades over time, requires regular topping up, and is highly dependent on soil moisture. Earthing chemicals are designed to be chemically stable, retain moisture better, and provide consistent low resistance for a much longer service life, reducing long-term maintenance costs.

No. AC earthing, DC earthing, and lightning protection earthing should each have their own separate, independently designed earth pit. Making Common all three into a single pit is a common installation mistake that allows a lightning surge to spread current into the entire electrical system instead of being safely contained, increasing the risk of damage to appliances, inverters, and building wiring.

Earth resistance should ideally be tested at least once a year, and more frequently in few cases which are as follow

1. areas with dry soil
2. high lightning activity
3. After Floods when your land area was dip in water for few days
4. After major earthquakes
5. if trees are growing near to earth pits
6. if sewerage water goes inside earth pit 

Testing ensures the earth pit still provides the low resistance value required for safe fault current dissipation.

Not automatically. A nearby tall structure only provides protection if your building falls within its calculated protection radius — a specific zone determined by the structure’s height and recognized lightning protection standards. Assuming protection without this calculation is a common and risky misconception.

A lightning arrester (or air terminal) is a device designed to intercept a lightning strike and safely direct its current to ground through a dedicated earthing system. For buildings with solar installations, rooftop equipment, or in areas with frequent thunderstorms, a properly designed lightning arrester is a fundamental safety component, not an optional extra.

Yes. When a lightning strike hits an unprotected structure, it seeks the fastest path to ground. Without a proper lightning arrester and earthing system, the surge can travel through concrete, walls, and wiring, severely damaging solar inverters, household appliances, and electrical circuits.

A surge protection device (SPD) protects electrical equipment from voltage spikes, including those induced by nearby lightning strikes, by diverting excess voltage to ground. A lightning arrester intercepts a direct strike, while an SPD protects connected equipment from surge effects. A complete protection system typically uses both together.

Yes. A solar PV system is not just panels and an inverter — it is a complete electrical system. Proper earthing (with AC, DC, and lightning earths kept separate) and a correctly sized lightning arrester are essential parts of a safe, code-compliant solar installation, not optional add-ons.

In many cases, both customers and installers try to reduce upfront costs by skipping protective components. Some installers also use inadequate or improperly designed earthing, making common AC, DC, and lightning earths into a single pit to save on materials and labor. These shortcuts significantly increase the risk of costly damage during a lightning event.

A qualified electrical engineer should inspect your installation to verify the presence and sizing of a lightning arrester, confirm that AC, DC, and lightning earthing are kept separate, and calculate whether your building falls within the protection radius of any nearby structures. Unicorn Energy Systems offers site assessments for this purpose.

Beyond routine panel cleaning and inverter checks, the earthing system and lightning arrester should be inspected and tested periodically, especially before monsoon season, to confirm they still provide adequate protection.
