The order is for Midsummer's proprietary production line for the manufacture of thin-film solar cells, DUO, excluding peripheral equipment but including installation, service and training of local factory personnel. The order is the largest single order in Midsummer's history. The bulk of the order value is expected to be booked as revenue in 2026.

In May last year, Midsummer received an order for machinery equipment that was manufactured in Sweden during the fall and has recently arrived at its final destination. Upscaling of production in the new factory is planned to take place in stages in line with established demand within the next few years.

“We have positive signals from the current market that our panels are attractive,” said Midsummer CEO Eric Jaremalm. “The ongoing orders also build invaluable experience and validation of our strategy and competence to handle such large projects. Our intention is to be able to offer complete solar cell factories to more customers worldwide.”

Midsummer DUO is a turnkey production system for mass production of durable, flexible and cadmium-free thin-film solar cells (CIGS) with a minimal CO2 footprint. With a compact design designed for high capacity, reliability and superior material utilization, the unique DUO system has taken the position as the most widespread production system for flexible thin-film solar cells in the world.
