A 5,000-Kilometer Delivery: Zealwe Tech Empowers Pakistan PV Laboratory Project

From Shanghai to Karachi — Building Global Trust Through Engineering Precision

Project Overview

As the global photovoltaic (PV) industry accelerates its growth, Zealwe Tech once again demonstrates the strength and reliability of China’s intelligent manufacturing.

In October, Zealwe’s engineering team successfully completed installation, commissioning, and technical training for two PV testing laboratory projects in Karachi, Pakistan, marking another milestone in the company’s international journey.

This project represents Zealwe’s first delivery to Pakistan, embodying the company’s vision of “Think globally, serve locally.”


1. From Shanghai to Karachi — A 5,000-Kilometer Mission

Every successful project begins with trust.

The Pakistani client sought to establish a PV testing laboratory fully compliant with IEC 61215 / IEC 61730 standards, to serve local module manufacturers and research institutions with reliable testing capability.

After multiple rounds of technical evaluation and solution comparison, the client chose Zealwe Tech’s complete PV testing equipment package. To ensure the systems operated with maximum precision, Zealwe dispatched senior engineers to Karachi for on-site installation, commissioning, and operator training — a 5,000-kilometer journey of dedication and excellence.

“At Zealwe, we never take trust for granted. Every delivery represents both responsibility and pride.”


2. Meticulous Preparation for Seamless Execution

Before departure, the engineering team conducted comprehensive preparation — compiling installation manuals, electrical drawings, calibration reports, and testing protocols.

They also simulated the commissioning process and assessed risks related to local voltage, climate, and power infrastructure, ensuring readiness for any on-site challenges.

Project Manager Li Zhibin summarized:
“No matter how far we travel, we go with full preparation and respect — because every Zealwe system carries our client’s trust and the reputation of Chinese manufacturing.”


3. Twelve Days of Precision and Persistence

Upon arrival, the team began immediate installation and debugging work. From UV chambers and mechanical load testers to environmental chambers, hail testers, and peel testers, every system underwent rigorous calibration and optimization.

When minor component damage occurred during transport, the engineers responded instantly — performing on-site repairs, refining control logic, and validating functionality under local high-temperature conditions.

The client’s project leader commented:
“Zealwe’s professionalism is remarkable. Their engineers always find the best solution in the shortest time.”

4. From Delivery to Empowerment

Following successful commissioning, Zealwe provided comprehensive technical training for local engineers — covering operational procedures, maintenance, alarm diagnostics, and software updates.

The team also shared hands-on insights from years of field experience, such as equipment health checks, calibration techniques, and accuracy optimization.

“It wasn’t just installation,” one client engineer said.
“It felt like a complete technical masterclass. I learned skills that will benefit me for years.”


5. Every Service, a Step Forward

During the project, Zealwe engineers recorded and resolved over ten improvement points, including refrigeration optimization, peel tester signal repair, and customized software upgrades.

Each enhancement was carefully documented in technical reports and data records, contributing to continuous product improvement and after-sales reliability.

At Zealwe, every service is treated as a new opportunity to improve — and every site, as a classroom for growth.


6. A Milestone Achieved — A Partnership Begins

After twelve intensive days, all systems passed final verification and were successfully handed over.
Behind every smiling photo was the shared achievement of trust, collaboration, and persistence.

For Zealwe Tech, each delivery is not just a project completion — it’s a reaffirmation of professionalism, reliability, and global commitment.
