Find insights into Swedish manufacturing – explore profiles, product highlights and market updates on leading companies across diverse industries.

Sweden’s solar-tech industry has evolved into a sophisticated ecosystem, far beyond the conventional rooftop panels. The country hosts manufacturers leading the way in everything from flexible, ultra-thin solar cells powering indoor IoT devices to building-integrated photovoltaics that displace traditional roofing materials. Swedish solar manufacturing is unique in that it targets niche applications and integrated solutions rather than competing with Asian giants on commodity panel production. The sector is divided into four different segments: thin-film flexible cells for consumer electronics (Midsummer, Exeger and Epishine); mounting and tracking systems for optimization of performance under Nordic conditions (Benders and Vaja); power electronics and integrated home energy management (Aira); and project development for commercial-scale solar (Alight). The following five companies are the strongest players in these categories.
