A solar panel for metal roofs.
Customized, elegant and integrated – solar power on your terms.

A revolution for roof tiles.
Solar power shaped to perform,
not to follow the norm.

Solar power for large areas and great ambitions.

Innovation in collaboration with the sun

It all began in 2004, when four people united in  a desire to revolutionize renewable solar energy. The result was Midsummer, creators of the unique production system Midsummer DUO, and the building-integrated solar panels for those who do not want to compromise between elegance and performance; Midsummer Solar Roofs.

Embracing the light

Our thin film solar cells are integrated into the roof and mounted to accentuate instead of hiding, with the bendable and thin profile of only two millimeters – about the thickness of a credit card.

But don’t be fooled: our solar cells perform, maintain consistent quality in all weathers and guarantee a discreet way to increase property value and lower energy costs.

Built from scratch

Midsummer was founded in 2004 by taking the machines and processes from CD production to producing durable and flexible solar cells. The machine is today known as Midsummer DUO, our major breakthrough in the industry, and a production asset to factories across the globe.

Optimized at a cellular level

Midsummer’s thin film solar cells, both in themselves and their different implementations on the roofs of Sweden, is pure engineering ingenuity.

Despite its light weight and thin profile, Midsummer produces up to 110 Wp per square meter, with a nominal power of 55 Wp per panel and an efficiency of up to 16% at the cellular level. All of this with a 10 year product guarantee and a full 80% performance guarantee for 25 years.

Sustainable energy deserves sustainable production

Midsummer is leading the pack when it comes to environmentally friendly production of solar panels. Because our production is efficient and our factory runs entirely on renewable energy from Sweden, we have minimized the carbon footprint from start to finish.

According to a study by Swerea IVF, our manufacturing process produces significantly less carbon dioxide than other manufacturers of solar panels – as little as 10%.

Designed in Sweden, made to last

Everything started here in Sweden, where Midsummer was founded in 2004. Instead of directly looking at the other side of the globe for manufacturing, we continued in Järfälla outside Stockholm.

Sweden has long been a leader in engineering, design safety and ambitions in green energy – something we encourage and want to continue to push for.
