PVTIME – North American photovoltaic manufacturer Heliene has confirmed a permanent reduction in its workforce at its Mountain Iron production site in Minnesota, with 93 roles set to be eliminated, representing over 30% of the plant’s original staffing level.
Formal notifications submitted to the Minnesota Department of Employment and Economic Development confirm that the restructuring took legal effect on 6 August. The redundancies cover roles in the production, quality assurance, technical research and human resources departments. All affected employment contracts will officially terminate on 4 October, and the company will continue to pay full salaries until that date. The permanent reduction in staffing levels will not involve closure of the facility, with 182 employees being retained to maintain essential on-site production activities.
According to Heliene’s human resources leadership, the capacity reduction is intended to align operational output with current customer order volumes and market demand. While the firm attributes the restructuring to unforeseen commercial market fluctuations, industry analysis suggests that the move is in response to persistent uncertainty over the future of US solar policy frameworks.
Plans for Heliene’s third manufacturing facility in Minnesota, which were previously scheduled, have been paused amid unclear prospects for federal solar investment tax credits. Lower-than-projected market demand has correspondingly reduced the plant’s utilisation rate.
Commissioned in September 2021, the Mountain Iron site has two photovoltaic module production lines with an annual manufacturing capacity of 800MW. During its development phase, the facility received more than $10 million in combined subsidies and dedicated loans from Minnesota state authorities, local municipal bodies, and industrial regeneration agencies, as part of regional efforts to expand domestic solar manufacturing capacity.
Heliene acquired and refurbished the site in 2017 following the collapse of former solar operator Silicon Energy due to operational underperformance. The site specialises in manufacturing high-efficiency bifacial solar modules with a high proportion of domestically sourced materials.
In April 2025, Heliene launched a second operational facility in Rogers, expanding its manufacturing footprint in Minnesota. Both sites are established to serve the US distributed solar and ground-mounted power station markets. However, broader industry headwinds have since slowed the company’s national expansion programme.
The Mountain Iron site has undergone successive reductions in its workforce over the past two years. Concurrent layoffs across local iron ore and manufacturing enterprises have increased pressure on the regional industrial park labour market. Based in Sault Ste. Marie, Ontario, Heliene focuses its North American market strategy on US production, heavily relying on incentives under the Inflation Reduction Act, including tax relief and domestic content subsidy schemes.
According to sector experts, the primary drivers of ongoing capacity rationalisation and workforce restructuring across domestic North American solar manufacturing operations are uncertain US solar policy implementation timelines, sustained competition from low-cost imported photovoltaic modules and slowing downstream solar installation demand.
