Should the U.S. prioritize domestic solar manufacturing even if it slows industry growth?

Industry leaders met at the PV CellTech USA conference to review the state of domestic solar production following the restart of operations in 2024. The discussions highlighted ongoing efforts by manufacturers like Imperial Star to scale capacity amid new government anti-stockpiling measures.

Why it matters

The US solar sector faces a critical shortage of skilled manufacturing workers as it attempts to localize production. Simultaneously, firms are navigating a complex regulatory environment as new import restrictions tighten supply chains for semi-finished components.

Imperial Star increased its workforce by 20% during the initial expansion phase in Tomball, Texas. The company aims for a 5GW production capacity by 2027, while annual demand for space-based solar cells is forecast at 100MW.

The players

Imperial Star

A solar technology company that operates a module manufacturing facility in Tomball, Texas.

PV CellTech USA

An annual industry conference that brings together solar manufacturers and policy experts to discuss technological and regulatory shifts.

The details

Manufacturers are transitioning from gallium arsenide to silicon-based cells for space applications due to supply constraints. To meet production goals, companies like Imperial Star are implementing internal training programs to bridge the current manufacturing knowledge gap.

Domestic solar cell production resumed in 2024.
Anti-stockpiling measures were implemented in September 2026.
Section 301 duty exclusions for equipment are set to expire on November 9, 2026.
Imports are barred starting December 4, 2026.
Imperial Star targets 5GW capacity by 2027.

Market Landscape

The impending expiration of Section 301 duty exclusions on solar manufacturing equipment signals a pivotal shift in federal industrial policy. This environment forces companies to balance immediate import barriers with the long-term necessity of scaling domestic infrastructure against global competitors.

Readers should anticipate shifts in solar product availability and pricing as firms adjust to new import deadlines. While increased domestic capacity may eventually lower costs, the immediate focus on workforce training suggests a gradual ramp-up rather than sudden market saturation.

The takeaway

The transition to domestic solar manufacturing is currently hindered more by labor shortages than by raw technological capability. Industry participants should monitor upcoming trade policy deadlines as these shifts will likely dictate the pace of facility expansion and equipment costs.
