Solar strategies in practice: Luxshare Precision builds manufacturing resilience with on-site solar

Recently, we launched the Solar Strategies in Practice series, a content initiative that highlights how leading companies integrate on-site solar into operations, investment planning, and sustainability goals.

After exploring Toyota’s automotive innovation and AEON’s retail transition toward net zero, this edition turns to Luxshare Precision, a global technology manufacturer specializing in consumer electronics, automotive, and communication systems. With its ambitious renewable energy rollout, most notably a 20 MWp rooftop solar installation in Vietnam which was officially connected to the grid and commenced operation in 2024, Luxshare showcases how solar power is evolving from a sustainability tool into a core element of industrial risk management.

Solar becomes a core pillar of Luxshare’s sustainability and energy strategy

At the heart of Luxshare’s sustainability roadmap lies the integration of environmental management across its entire business system. The company aims to establish a green, low-carbon, and efficient global operation, closely aligned with its role as a trusted precision manufacturing partner for brands like Apple.

Energy security has become a strategic concern. Rising electricity costs and stricter supply chain carbon requirements have pushed Luxshare to see solar not as a cost center but as energy insurance, a critical tool to ensure operational continuity.

Solar power serves three key roles for Luxshare:

• A direct decarbonization lever that reduces Scope 2 emissions at production sites.

• A resilience mechanism that shields operations from grid instability.

• A financial hedge that has been locked in stable, low-cost electricity for decades.

Vietnam’s power crisis marks a turning point for industrial energy strategy

Northern Vietnam, a major manufacturing hub for electronics and textiles, experienced severe power shortages in 2023. Rolling blackouts forced factories to halt production, causing millions of losses.

For high-precision manufacturers like Luxshare, even a millisecond voltage drop can scrap entire production batches. The crisis underscored a new industrial reality: energy security equals production security.

This pattern is not unique to Vietnam. Across Europe, extreme weather and aging grids have caused similar supply disruptions. As a result, on-site solar and storage have shifted from optional solutions to mandatory infrastructure for manufacturers worldwide.

Luxshare’s response is rooftop solar as an energy moat

To strengthen energy resilience, Luxshare invested in a 20 MWp distributed rooftop solar system at its Vietnam campus. The installation is expected to generate approximately 21 million kWh of clean electricity annually, contributing to a reduction of nearly 20,000 tons of carbon emissions and saving almost 6,800 tons of standard coal.  

Thus, the initiative directly addresses three operational challenges:

Reliable power during shortages: The system produces over 21 GWh of clean electricity annually, covering about 30 percent of daytime factory demand and maintaining critical operations during power rationing.

Protection from energy price volatility: By generating its own renewable electricity, Luxshare secures low, predictable prices for up to 25 years. For context, industrial electricity costs in Europe (about €0.20 per kWh) are more than twice those in Vietnam, suggesting even higher savings potential for similar projects abroad.

Enhanced supply chain compliance: Luxshare’s renewable deployment directly supports the carbon-neutral sourcing standards of its global clients, reinforcing its position as a preferred supplier in competitive markets.

Rooftop solar with LONGi modules helps Luxshare Vietnam mitigate grid outages

To address recurring power constraints in northern Vietnam, Luxshare Precision expanded on-site generation with a new rooftop PV system of around 8 MW, built with LONGi modules. The plant covers about 30% of the facility’s electricity needs, lowering reliance on the public grid and mitigating the risk of production interruptions during shortages. The result is greater energy resilience, more predictable operating costs, and a measurable reduction in the site’s carbon footprint.

Solar is the new industrial baseline

Luxshare’s case shows a fundamental shift for solar. Energy resilience and green value have become the twin engines of competitiveness. From Southeast Asia to Europe, rooftop photovoltaics are no longer a symbolic gesture. They are a strategic infrastructure for modern industry. As manufacturers face volatile energy markets and rising ESG expectations, distributed solar emerges as both a shield and a strategy, protecting operations while powering growth.

LONGi strengthens its global C&I portfolio with advanced back contact technology and lightweight solutions  

In late 2023, LONGi took a major step forward in advancing its solar technology and expanding its product offering for commercial and industrial (C&I) applications. The company introduced its proprietary HPBC (Hybrid Passivated Back Contact) technology, marking a new era of high-performance solar modules designed to maximize energy yield and reliability for distributed generation. In 2024 and 2025, this innovation evolved into its second generation with the launch of the Hi-MO X10 Series, alongside the Guardian Light Design module engineered specifically for low-load bearing roofs, a limitation that affects countless businesses worldwide, particularly in the logistics and warehousing sectors.

Building on years of field experience, LONGi has become a trusted partner for C&I customers by combining cutting-edge technology with deep engineering expertise and dependable long-term service. The new Hi-MO X10 Series offers excellent low-light performance, minimal degradation, and enhanced mechanical strength – all key advantages for industrial rooftops exposed to variable weather or structural limitations.They also demonstrate reduced degradation in hot, humid climates, a proven advantage for installations across Southeast Asia and Southern Europe, where high temperature and moisture levels typically challenge long-term performance. This resilience, combined with LONGi’s rigorous quality control and manufacturing standards, helps minimize maintenance requirements during operation and ensures consistent reliability throughout the system’s lifetime.

With proven experience across Europe, the Nordics, and Asia, LONGi continues to help businesses achieve greater energy independence, operational stability, and CO₂ reduction, setting new benchmarks for efficiency and trust in the global C&I solar market.
