Power the Americas with Solar Trade — Connect US Buyers with Latin American Suppliers

Solar energy is one of the fastest-growing segments in the global renewable energy transition. For US buyers and Latin American suppliers, the cross-border trade in solar panels, inverters, mounting systems, and balance-of-system components represents a multi-billion-dollar opportunity. This page covers the key product categories, supply chain dynamics, compliance requirements, and how Coppermont facilitates trade between the United States and Latin America in the solar energy sector.

Products and Grades in This Cluster

The solar energy trade cluster encompasses a wide range of equipment and materials. The most prominent product category is photovoltaic (PV) modules, which are available in monocrystalline, polycrystalline, and thin-film technologies. Monocrystalline panels, with efficiencies exceeding 22%, dominate the utility-scale and commercial markets. Polycrystalline panels, slightly less efficient but more cost-effective, are common in residential installations. Thin-film modules, such as cadmium telluride (CdTe) and copper indium gallium selenide (CIGS), are used in building-integrated photovoltaics and large-scale ground-mount projects where space is not a constraint.

Inverters are another critical component. String inverters are the standard for residential and small commercial systems, while central inverters are used in utility-scale plants. Microinverters and power optimizers are increasingly popular for maximizing energy harvest in shaded or complex rooftop arrays. Mounting systems—fixed-tilt, single-axis trackers, and dual-axis trackers—vary by project type and geography. Balance-of-system components include wiring, combiner boxes, disconnect switches, monitoring equipment, and battery storage systems for hybrid installations.

Specifications matter greatly in cross-border trade. US buyers typically require panels certified to UL 1703 or UL 61730 standards, while inverters must meet UL 1741 or IEEE 1547 for grid interconnection. Latin American suppliers often produce to IEC standards (IEC 61215, IEC 61730), which are widely accepted in the Americas but may require additional testing for US projects. The grade of aluminum in mounting structures, the type of glass used in panels, and the warranty terms—typically 25 years for performance and 10–12 years for product—are key differentiators.

Latin America and Africa Suppliers

Latin America has emerged as a significant manufacturing hub for solar energy components, driven by abundant raw materials, favorable trade agreements, and growing domestic demand. Mexico is the largest producer in the region, with several factories assembling PV modules and inverters for export to the US under the United States-Mexico-Canada Agreement (USMCA). Brazil has a robust solar industry, with manufacturers producing panels and inverters for its massive internal market and for export to other South American countries. Chile and Argentina are developing local production of mounting structures and balance-of-system components, leveraging their strong mining sectors for aluminum and copper.

Colombia and Peru are also expanding their solar manufacturing capabilities, particularly in module assembly and racking systems. In Central America, Costa Rica and Guatemala have small-scale producers focusing on off-grid and residential solar kits. While Africa is not the primary focus of this page, it is worth noting that South Africa and Morocco have growing solar manufacturing industries that occasionally export to Latin America or compete in US markets through third-country trade routes.

For US buyers, sourcing from Latin America offers several advantages: shorter shipping times compared to Asian suppliers, reduced logistics costs, and preferential tariff treatment under USMCA or other bilateral agreements. Many Latin American suppliers also provide bilingual technical support and are familiar with US electrical codes and installation practices. However, buyers must verify factory certifications, quality control processes, and financial stability before entering into long-term supply agreements.

US Buyer Types

US buyers of solar energy equipment span a diverse range of industries and project scales. Utility-scale developers procure hundreds of megawatts of PV modules, inverters, and trackers for large solar farms. These buyers typically issue requests for proposals (RFPs) with strict technical specifications, delivery schedules, and warranty requirements. They often work with engineering, procurement, and construction (EPC) contractors who manage the supply chain and installation.

Commercial and industrial (C&I) buyers include warehouse operators, retail chains, manufacturers, and office building owners who install rooftop or ground-mount solar systems to reduce electricity costs and meet sustainability goals. These buyers usually work with solar installers or system integrators who handle procurement, permitting, and installation. Residential solar installers are another major buyer segment, purchasing panels, inverters, and racking for homes across the US. They prioritize reliability, ease of installation, and competitive pricing.

Government entities, including municipalities, school districts, and federal agencies, also procure solar equipment for public buildings and infrastructure projects. These buyers often require compliance with Buy America provisions or other domestic content rules, which can affect sourcing from Latin America. Agricultural buyers, such as farms and ranches, use solar for irrigation pumping, grain drying, and remote power needs, often seeking durable, off-grid solutions.

Procurement processes vary. Large developers use formal RFPs and multi-year contracts, while smaller installers may purchase through distributors or directly from manufacturers. Key decision factors include price per watt, module efficiency, warranty terms, delivery lead times, and the supplier's track record. US buyers increasingly demand transparency in the supply chain, including documentation of raw material origins and labor practices.

Certifications and Compliance for This Cluster

Compliance is a critical aspect of solar energy trade between the US and Latin America. For PV modules, UL 1703 (now UL 61730) certification is mandatory for US projects, covering fire safety, mechanical load, and electrical performance. Inverters must be certified to UL 1741, which includes anti-islanding protection and grid interconnection requirements. For grid-tied systems, IEEE 1547 compliance ensures the inverter can safely interact with the utility grid.

International Electrotechnical Commission (IEC) standards are widely used in Latin America and are often accepted in the US for certain projects, especially those not requiring UL listing. However, many US utilities and building codes explicitly require UL certification, so Latin American suppliers must obtain UL listing to access the full US market. The California Energy Commission (CEC) also maintains a list of eligible equipment for the state's solar incentive programs, which is a de facto standard for many US buyers.

Environmental and labor certifications are increasingly important. Suppliers may need to demonstrate compliance with the Conflict Minerals Rule (SEC Rule 13p-1) regarding tin, tantalum, tungsten, and gold used in electronics. ISO 9001 (quality management) and ISO 14001 (environmental management) certifications are common requirements in RFPs. For projects funded by the US government, the Buy America Act may require that steel and iron components be domestically produced, though waivers exist for certain solar components. Latin American suppliers must carefully navigate these rules to avoid customs delays or contract disqualification.
