What They Do

Midsummer AB is a Swedish industrial technology company specializing in the development, manufacturing, and sale of flexible thin-film CIGS solar cells, solar roofs, and the production equipment used to create these cells (source: midsummer.se). Founded in 2004, the company has evolved from producing manufacturing equipment to a vertically integrated business that spans cell production equipment, solar roof products, and installed rooftop solar solutions (source: midsummer.se). Their core technology, CIGS thin-film photovoltaics, is characterized by being thin, lightweight, flexible, and discreet, offering easier installation compared to conventional glass panels (source: nasdaq.com). Midsummer markets its solar panels under the SLIM, WAVE, and BOLD product lines, each tailored for different roof types, and also sells the DUO system for mass production and the UNO system for research and development use by universities and institutions (source: midsummer.se).

The company targets a diverse customer base including construction firms, roofing companies, solar installation companies, research institutions, and end customers purchasing solar roofs directly (source: nasdaq.com). Additionally, Midsummer sells production equipment and related services to strategically selected industrial partners, including overseas manufacturers (source: nasdaq.com). A key differentiator is their focus on lightweight flexible CIGS panels and the proprietary DUO manufacturing system, which is reportedly the most widespread manufacturing tool for flexible CIGS solar cells globally (source: nasdaq.com). The company also emphasizes the environmental benefits of its technology, claiming its panels have a carbon footprint approximately one-tenth that of traditional silicon solar panels (source: midsummer.se).

Projects & Track Record

Midsummer has a documented history of equipment sales and solar roof deployments rather than utility-scale solar farms (source: midsummer.se). One notable project includes a 667 kW field installation of thin and lightweight solar panels for Green Energy Group, which was the company’s largest single order at the time (source: marketscreener.com). Another significant project involved supplying a production line to a Russian nanotechnology and nanomaterials center under a framework agreement with Rusnano; this production line was manufactured in Järfälla and destined for installation in Saransk, Russia (source: midsummer.se). In 2026, Midsummer announced a binding agreement with PT Metalogika Rekayasa Sistem to establish manufacturing in Indonesia, initially targeting 20 MW per year capacity with potential expansion toward 200 MW annually (source: pv-magazine.com).

Recent Developments

Recent developments for Midsummer have focused on international manufacturing expansion and capital actions. In September 2026, the company signed a binding investment and industrialization agreement with Indonesian firm PT Metalogika Rekayasa Sistem to build a flexible CIGS solar cell and module plant in Indonesia, with Midsummer supplying the DUO system, equipment, services, and taking a minority stake in the joint venture (source: nasdaq.com). In late 2025, Midsummer announced a fully guaranteed rights issue of approximately SEK 175 million and reached an agreement on debt conversion, while also expanding its Colombian operations from 15 MW to between 100 MW and 200 MW (source: inderes.fi). The company’s 2025 quarterly reports showed materially improved operating results and increased sales of machinery and solar panels (source: midsummer.se).

Working There

Midsummer hires across a variety of functions including industrial manufacturing, engineering, product development, project delivery, sales, and international expansion, reflecting its diverse operations in factory equipment, solar product sales, and factory startup activities (source: midsummer.se). The company’s careers portal provides a public contact channel at [email protected] and outlines a dedicated recruitment and privacy-processing flow (source: careers.midsummer.se). The repeated launches of new factories and production lines in Sweden, Italy, Colombia, and Indonesia suggest ongoing hiring opportunities tied to manufacturing scale-up, equipment installation, and commercial growth (source: nasdaq.com).
