Swedish specialist in the field of thin-film solar panels Midsummer has secured a follow-up order for machines for a factory for the production of thin-film solar cells.
The contract, worth SEK 236 million ($14.8 million), is the largest order in the company’s history. It includes Midsummer’s own production line for sustainable, flexible CIGS solar cells, known as DUO. The deal does not include peripheral equipment, but does include installation, service and training of local factory personnel.
It follows an initial order of 143 million Swedish kronor for solar energy production equipment in May 2025 for the same customer, an unnamed Swedish industrial and defense group, covering a 15 MW turnkey line. Midsummer said at the time that it was the first phase of a factory, with the intention of adding capacity at a later stage.
Midsummer previously indicated that the factory would be located in a non-European country. In November 2025, pv magazine Latin America reported that Midsummer was working with Swedish aerospace and defense company Saab on a CIGS factory in Colombialinking a memorandum of understanding, first signed in 2024, to last May’s order. In the latest update, Midsummer said that the 2025 order recently arrived at its final destination.
Midsummer CEO Eric Jaremalm said the company has seen positive signs from the current market. “Our intention is to offer complete solar cell factories to more customers worldwide,” he said.
In April 2024, Midsummer said it was building one 200 MW CIGS solar module factory in south-eastern Sweden to serve the European market. At the time, the company said production would begin in 2026, ahead of full operation in 2028.
Midsummer also has a production factory for thin-film solar panels in Italyoperational since 2024.
