Midsummer to supply production equipment for a 100-200 MW solar plant in Colombia as part of Saab's Gripen sale offset commitment

Swedish solar energy company Midsummer will supply production equipment for a previously announced plant in Colombia with an annual production capacity of 100-200 MW. This is part of defense and security group Saab's offset commitment to the country in connection with the sale of jet fighter Gripen.

Midsummer will sell and supply all production equipment for the factory, including the company's proprietary DUO machines for the manufacturing of thin-film solar cells. Each DUO unit has an annual production capacity of 5 MW.

The Colombian production facility will become a production hub for the entire Latin American market and will be able to supply solar panels to customers across the continent.

A more detailed project plan will be developed together with Saab in late 2025.

In May, Midsummer received a first order for production equipment with a capacity of 15 MW from Saab for the Colombian factory, which will now be gradually expanded to a capacity of at least 100 MW.
