A look at the solar manufacturing sector reveals that many of the world’s leading solar panels originate from just a few key countries. For years, China dominated the landscape, but a significant shift is underway. Vietnam has rapidly emerged as a critical hub in the global solar supply chain, attracting billions in investment and hosting facilities for some of the industry’s biggest names.
This transition creates a strategic opportunity for new investors, yet it also raises a crucial question: where exactly in Vietnam should one build a factory? The country is not a monolith; its regions offer distinct advantages and challenges. Selecting the right industrial zone is a foundational decision that can influence everything from logistics costs and labor availability to long-term profitability.
This analysis compares Vietnamโs primary industrial regionsโBac Ninh, Hai Phong, and Binh Duongโto help guide an informed site selection decision.
The Northern Powerhouse: Proximity to Global Supply Chains
Northern Vietnam has become the country’s primary cluster for high-tech and solar manufacturing. Its strategic proximity to established supply chains in Southern China, combined with significant government investment in infrastructure, makes it a compelling choice for businesses focused on export.
Hai Phong: The Premier Gateway for Exports
For any business model centered on exporting finished solar modules, Hai Phong is a top consideration. Its primary advantage is logistics.
Infrastructure: The city is home to Lach Huyen, Vietnam’s first deep-water port, capable of accommodating large container ships. This direct access significantly reduces transport time and costs for shipping to international markets like North America and Europe. The port’s proximity to major highways also facilitates the efficient movement of raw materials and finished goods throughout the broader Red River Delta region.
Government Support: As a key economic zone, Hai Phong offers some of the country’s most attractive investment incentives, including extended corporate income tax holidays and exemptions on import duties for raw materials and machinery.
Labor Market: The region has a well-established industrial workforce, although competition for highly skilled engineers and managers can be intense due to the concentration of large-scale manufacturing operations.
Bac Ninh: The Electronics and High-Tech Ecosystem
Located just east of Hanoi, Bac Ninh province has branded itself the ‘Silicon Valley of Vietnam.’ It is home to massive electronics manufacturing complexes, creating a unique ecosystem that benefits solar producers.

Skilled Labor: The long-standing presence of global electronics giants has cultivated a deep pool of labor experienced in sophisticated manufacturing processes, quality control, and production line management. This can reduce the time and cost associated with training new staff. The solar panel manufacturing process shares many principles with electronics assembly, making the region an excellent source for talent.
Supply Chain Synergy: The province has a dense network of suppliers for industrial components, automation services, and logistics. This proximity can improve operational efficiency and reduce lead times for essential materials and services.
Infrastructure: While not a port city, Bac Ninh offers excellent road and rail connectivity to both Hanoi’s Noi Bai International Airport and the port of Hai Phong, making it a viable logistics hub.
The Southern Manufacturing Core: Binh Duong Province
While the North has captured recent headlines in the solar sector, Southern Vietnam, particularly Binh Duong province, remains the country’s traditional industrial heartland. Located adjacent to Ho Chi Minh City, it offers a different set of advantages rooted in its diverse manufacturing base and large domestic market.
Diversified Industrial Base: Unlike the North’s high-tech focus, Binh Duong hosts a wide range of industries, from textiles and furniture to machinery and food processing. This diversity creates a resilient and flexible business environment with a broad supplier network.
Logistics: The province is strategically positioned near Tan Son Nhat International Airport and the bustling Cat Lai Port in Ho Chi Minh City, a major hub for trade within the ASEAN region.
Labor Market: Binh Duong attracts a massive influx of workers from across Vietnam, providing a large and readily available general labor force. While the cost of labor is competitive, sourcing specialized technical talent may require more effort than in Bac Ninh.
Domestic Market Access: For manufacturers aiming to serve Vietnam’s growing domestic solar market, a southern location provides direct access to the country’s economic center and largest population center.
Key Factors for Your Site Selection Analysis
Choosing between these regions requires aligning their specific strengths with your business strategy. There is no single ‘best’ location, only the best fit for your objectives.
Based on experience from J.v.G. turnkey projects, the analysis often comes down to these four factors:
-
Export vs. Domestic Focus: If your primary market is North America or Europe, the logistical advantages of Hai Phong’s deep-water port are a decisive factor. If you plan to serve Vietnamese or Southeast Asian markets, Binh Duong’s proximity to Ho Chi Minh City is a key advantage.
-
Labor Requirements: If your production line requires a high degree of automation and specialized technical skill, Bac Ninh’s ecosystem provides a head start in recruitment. For operations requiring a larger, more general workforce, Binh Duong offers a more extensive labor pool.
-
Investment Profile: The total investment for a solar panel factory can be influenced by land lease costs, which vary significantly between zones. Highly developed zones in Bac Ninh and Hai Phong may command higher prices than emerging parks in surrounding areas or Binh Duong. Thorough research into specific industrial park fees is essential.
-
Supply Chain Strategy: Consider where your key suppliers for materials like glass, aluminum frames, and junction boxes are located. Positioning your factory to minimize inbound logistics costs can provide a significant competitive advantage.
A comprehensive site selection process is a cornerstone of establishing a turnkey solar production line. It mitigates risk and sets the foundation for operational success. This includes meeting specific factory building requirements for seismic stability, floor loading, and cleanroom environments.
Frequently Asked Questions about Establishing a Solar Factory in Vietnam
What are the first steps for a foreign investor?
The initial steps include preliminary market research, identifying potential local partners, and engaging with legal and investment consultants to understand the legal framework. This is followed by due diligence on specific industrial zones and an application for an Investment Registration Certificate (IRC).
How long does the setup process typically take?
With a structured approach, a small to medium-sized solar module line (e.g., 20โ50 MW) can become operational in 12 to 15 months. This timeline includes site selection, legal entity formation, factory construction or retrofitting, equipment procurement, and commissioning.
What are the main challenges to anticipate?
Investors should prepare to navigate a complex bureaucracy, which can be streamlined by working with experienced local advisors. Other potential challenges include supply chain disruptions, competition for skilled labor in high-demand areas, and the need to understand local business customs and regulations.
Your Next Steps in Site Selection
Vietnam presents a compelling and viable location for new solar manufacturing ventures. Success, however, depends on meticulous planning, and the first critical step is choosing the right industrial zone. The northern regions of Hai Phong and Bac Ninh offer a robust, export-focused ecosystem with a strong infrastructure and a high-tech talent pool. In contrast, the southern province of Binh Duong provides access to a vast labor force, a diversified industrial base, and the country’s largest domestic market.
A careful evaluation of your business model against the distinct advantages of each region will reveal the optimal path forward, transforming a complex decision into a strategic business advantage.
