Tigo Energy and CELTEC Enhance Safety and Compliance in Central American Solar Projects

Key Terms

nec 2017/2020 regulatory

NEC 2017/2020 refers to the 2017 and 2020 editions of the National Electrical Code, a widely adopted set of safety rules for electrical design, installation and inspection. For investors, these editions matter because they set standards that can change project costs, require equipment upgrades, and affect regulatory approval or insurance for buildings and infrastructure — like a rulebook update that can force businesses to retrofit systems or alter product designs.

rapid shutdown technical

A rapid shutdown system is a safety feature for solar panel installations that quickly cuts the electrical output of rooftop modules during emergencies so wires and panels become low‑voltage and safer to handle. Investors should care because required compliance, equipment choices, and installation costs affect product demand, project timelines, and liability exposure—think of it as a car’s airbag: a mandated safety add‑on that influences design, price and marketability.

mlpe technical

Module-level power electronics (MLPE) are small devices—like tiny smart adapters—attached to each solar panel to optimize and monitor its output individually, instead of managing the whole array as one. For investors, MLPE can meaningfully change a solar project’s performance, operating costs and product competitiveness because they boost energy yield, improve fault detection and can alter installation and maintenance economics.

Collaboration broadens distribution of NEC-compliant solar technologies from Tigo, promoting safety and compliance as solar adoption accelerates in Central America and the Caribbean.

PANAMA CITY--(BUSINESS WIRE)-- Tigo Energy, Inc. (NASDAQ: “TYGO”) (“Tigo” or “Company”), a leading provider of intelligent solar and energy software solutions, today announced a strategic partnership with regional distributor of renewable energy solutions, CELTEC. Through the partnership, CELTEC will distribute Tigo Rapid Shutdown solutions as well as its full portfolio of optimizers and products across Central America and the Caribbean. This collaboration comes amid the sustained growth of solar energy across Central America and the Caribbean, which has led to evolving regulatory frameworks and the need for enhanced safety standards. The partnership also facilitates access to technologies aligned with NEC 2017/2020 requirements, which are already mandatory in Panama and are progressively being adopted in other Central American and Caribbean markets.

“The implementation of NEC 2020 in the markets we serve always marks a turning point in the way solar projects are designed, particularly with regard to first responder safety,” said Darío Torres, CEO of CELTEC. “Safety must be a fundamental pillar in any solar project, whether residential, commercial, or utility-scale. With Tigo, we strengthen our value proposition for installers and developers by offering a robust technical solution that protects people, infrastructure, and investment.”

One of the cornerstones of this collaboration is the Tigo TS4-A-2F, a reliable and cost-effective rapid shutdown solution that complies with the latest module-level shutdown requirements set forth in NEC 2017/2020. Certified by IEC and UL for global acceptance, the TS4-A-2F also carries UL PVRSS certification, helping to enable compatibility with the broadest network of inverters on the market, many of which feature Tigo RSS transmitter integration. By connecting to two modules, the TS4-A-2F can reduce installation time and can enable up to 16% fewer connections in a 14-panel string compared to single-channel MLPE solutions, streamlining fieldwork, reducing potential points of failure, and increasing overall system reliability.

“Within the framework of our partnership, the safety of first responders has become a central consideration in the design and installation of solar projects across residential, commercial, and utility-scale applications,” said Jing Tian, chief growth officer at Tigo Energy. “Through this alliance, we aim to contribute to the sustainable growth of the solar market in Central America and the Caribbean, driving the adoption of technologies that combine innovation, regulatory compliance, and a strong focus on safety and quality. These are the key elements for building a sustainable future for the region’s solar energy sector.”
