Stäubli is a PV component market leader, highlighted by the Original MC4 connector — which the company estimates connects more than 50% of PV capacity worldwide. More solar projects worldwide means more PV component capacity is needed of course, and Stäubli North America announced major investments this week to expand its manufacturing and assembly operations in South Carolina and California.

“We plan to steadily increase our made-in-America products at these manufacturing facilities,” said Brian Mills, Head of Renewable Energy, Stäubli North America.

The company established its North American presence in 1980 in Duncan, South Carolina. Today, the 103,000-square-foot facility houses manufacturing, logistics and personnel to operate and support the company’s different divisions. In 2011, the company expanded with a 43,000-square-foot manufacturing facility for electrical PV connectors and other products in Windsor, California.

In addition to the Original MC4 connector, Stäubli North America has a history of manufacturing a wide range of solar solutions including junction boxes, in-line fuses, dc wire harnesses, and more eBOS products domestically.

“Increasing our already established solar connector manufacturing footprint in the U.S. puts Stäubli in a strong position to support the increasing demand for domestically made components driven in part by the Inflation Reduction Act of 2022,” Mills added.

Stäubli North America has added capabilities to its locally-based Field Engineers, Design Engineers, and test lab resources to now offer a new customer support offering of Field Services and technical training.

“This comprehensive support is unique in the industry and extends through each critical stage of a solar project: from initial design, through pre-construction and construction, right up to the operational phase. This includes support of proper product selection and assembly, optimized design for limited waste and power loss, and proper implementation of the product in the field to ensure that our customers achieve safe and reliable solar installations.” said Mills.
