Hounen Solar America will commence the construction of a 3 GW solar module manufacturing facility in South Carolina in 2026.

Hounen said the facility, to be located in Summerville, will span 1,019,200 sq. ft and incorporate advanced automation, smart manufacturing, and high-efficiency solar technology.

As of 2024, the company had a module manufacturing capacity of 1 GW from its 200,720 sq. ft facility in Orangeburg, South Carolina.

Hounen Solar provides solutions for residential, commercial rooftop, and utility-scale solar projects.

Several U.S. solar companies have recently announced plans to set up module manufacturing plants.

Recently, another module manufacturer, First Solar, announced it would invest approximately $330 million to set up a 3.7 GW module manufacturing facility in Gaffney, South Carolina, to onshore the final production process for its Series 6 Plus modules. The manufacturing facility is expected to commence commercial operations by the second half of 2026.

In June, Singapore-based Bila Solar said it had begun production of U.S. domestic content modules at its manufacturing facility in Indianapolis, Indiana. The company said that this step marks its entry into full-scale U.S.-based solar manufacturing, utilizing American-made solar cells to produce high-efficiency panels.

In March this year, material sciences company Corning, crystalline silicon solar cell manufacturer Suniva, and solar module producer Heliene said they are establishing the first fully U.S.-made solar module supply chain. The collaboration aims to provide the U.S. market with solar modules made using locally manufactured polysilicon, wafers, and solar cells.

Despite the introduction of policies inimical to the development of clean energy, the U.S solar industry continued to grow in the second quarter of 2025, with module manufacturing capacity reaching 55.4 GW, according to a report by Wood Mackenzie and Solar Energy Industries Association. This growth exceeds the yearly solar installations when the factories are running at full capacity.
