A solar module factory is more than an assembly line—it’s a critical node in a global supply chain. Its efficiency and profitability depend on the seamless flow of raw materials from across the world and finished products to international markets.
For entrepreneurs considering El Salvador as a manufacturing base, the country’s strategic location on the Pacific coast is a significant advantage. Realizing this advantage, however, requires a thorough understanding of the local logistical landscape.
This analysis provides a practical overview of importing raw materials and exporting finished solar modules from El Salvador, examining the key ports, customs procedures, and inland transportation that form the backbone of any successful manufacturing operation in the region.
The Strategic Importance of Port Infrastructure
The success of a solar manufacturing venture hinges on logistical efficiency. A delay in receiving a single critical component, like solar cells from Asia or specialized glass from Europe, can halt production entirely. Likewise, inefficient export processes can lead to missed delivery deadlines and damaged customer relationships.
El Salvador’s primary logistical assets are its two major Pacific ports: the established Port of Acajutla and the modern Port of La Unión. Proximity and access to these vital gateways should be a deciding factor when choosing a factory location.
Importing Raw Materials: A Practical Overview
A solar module assembly line requires a steady flow of imported components. Key materials—including solar glass, EVA encapsulant, solar cells, backsheets, and aluminum frames—are typically sourced from suppliers in Asia and Europe, making ocean freight the only viable transportation method.
The Port of Acajutla: The Primary Gateway
As the country’s largest and most active seaport, the Port of Acajutla handles the majority of its containerized cargo. For a new solar factory, it will almost certainly be the main point of entry for raw materials.
According to data from the Port Authority of Acajutla (CEPA), the port can handle a consistent flow of 40-foot containers, the standard for shipping solar components. The customs clearance timeline is a critical factor. Based on experience from J.v.G. turnkey projects in similar regions, a well-prepared shipment with all documentation in order can clear customs within 48 to 72 hours. If a shipment is flagged for physical inspection or has documentation errors, however, the process can extend to 5–7 business days.
Engaging a reputable local customs broker is not just a recommendation—it’s essential for navigating regulations and minimizing delays.
Logistical Costs and Considerations
Budgeting for logistics requires a detailed understanding of costs beyond the price of the materials themselves. These include ocean freight, which varies significantly based on origin port and global shipping demand, and port handling fees (THC), which are standard charges for unloading containers.
Customs duties and tariffs can also be substantial. These costs may be mitigated if the factory is established within a designated Free Trade Zone (FTZ), which typically allows for the duty-free import of raw materials used in manufacturing for export.
Finally, consider inland transportation, which is the cost of moving a container from the port to the factory. For instance, ground transport for a 40-foot container from Acajutla to an industrial park in the San Salvador metropolitan area typically ranges from $400 to $600 USD.
These logistical expenses are a significant part of the overall investment requirements for a solar factory and must be carefully factored into any business plan.
Exporting Finished Solar Modules: Reaching Global Markets
Once modules are manufactured and tested, they must be packaged securely for export to customers in North, Central, and South America, or even further afield. The export process largely mirrors importation but has its own unique considerations.
Packaging and Containerization
Finished solar modules are both fragile and valuable, so proper packaging in specialized crates is critical to prevent breakage during transit. A standard 40-foot high-cube container, the most common shipping type, can typically hold between 600 and 800 modules, depending on their wattage and physical dimensions. The total weight and volume of a full container determine export shipping costs.
The Port of La Unión: A Future-Oriented Option
Located in the east, the Port of La Unión is a newer, more modern facility. While currently underutilized compared to Acajutla, its strategic importance is expected to grow. For a solar manufacturer with a long-term vision, its modern infrastructure could offer future advantages, particularly for shipments targeting markets across the Pacific. This forward-looking perspective is key for businesses planning operations for the next decade and is central to the guidance within the pvknowhow.com e-course.
Export Documentation and Certification
To export finished goods, a manufacturer must provide a standard set of documents, including a commercial invoice, a detailed packing list, and a certificate of origin. The modules themselves must also comply with international standards. Ensuring products meet these requirements is crucial for market access and is a topic we cover in detail in our guide on solar module certification processes.
Inland Transportation: Connecting Ports to Your Factory
El Salvador has a relatively well-developed road network connecting its major ports to its industrial centers. The Pan-American Highway (CA-1) and the coastal highway (CA-2) serve as the primary arteries for freight transport. The journey from Acajutla to the main industrial zones around the capital, San Salvador, is approximately 85 kilometers and typically takes 2–3 hours by truck, traffic permitting.
However, entrepreneurs in the region frequently highlight the challenge of “last-mile” logistics. While the main highways are reliable, the quality of access roads leading to specific industrial parks can vary. This variability makes a thorough site visit and infrastructure assessment an essential part of the initial planning phase—a critical step detailed in our comprehensive guide on how to start a solar factory.
Frequently Asked Questions (FAQ)
What are the main advantages of El Salvador’s location for logistics?
El Salvador’s primary advantage is its direct access to the Pacific Ocean, providing a gateway to markets in Asia and the Americas. Its proximity to the large North American market is a significant benefit for export-oriented manufacturing.
Are there free trade zones (FTZs) that benefit solar manufacturers?
Yes, El Salvador has several FTZs that offer significant fiscal incentives, including exemptions from import duties on raw materials and machinery, as well as income and municipal tax exemptions. Operating within an FTZ can significantly improve the financial viability of a solar manufacturing project.
How long does it typically take for a container to travel from Acajutla to San Salvador?
Under normal conditions, truck transit time is between 2 to 3 hours. However, businesses should plan for potential delays due to traffic congestion, especially during peak hours around the capital.
What is the role of a customs broker in this process?
A customs broker is a licensed professional who acts as an agent for the importer or exporter, preparing and submitting all necessary documentation to facilitate customs clearance. Their local expertise is invaluable for ensuring compliance and preventing costly delays.
Conclusion and Next Steps
El Salvador offers a solid logistical framework for entrepreneurs planning to establish a solar module manufacturing facility. Its functional ports, established road network, and strategic location create a viable environment for connecting to the global supply chain.
Capitalizing on these advantages, however, is not automatic. Success requires meticulous planning, a clear understanding of costs and timelines, and strong partnerships with local logistics and customs experts. Understanding these operational details is fundamental to building a robust and realistic business plan.
