About us

Midsummer is a Swedish solar energy company that installs discrete solar roofs that we manufactured in Järfälla with 90% lower carbon dioxide footprint than traditional solar panels. We have a high-tech Swedish product and own the entire value chain from development and production to installation. Under the Midsummer Machinery brand, we supply production systems for flexible thin film solar cells.

Diskreta solcellstak från Sverige

Midsummer tillverkar diskreta och driftiga solcellstak. Så diskreta att de blir ett med ditt tak. Och så driftiga att de gör sitt jobb utan att flexa ut, ta långhelg eller semester.

För att tala klarspråk kan vi kalla dem för osynliga hjältar i solskensskrud. Tillverkade av Midsummer, tillverkade i Järfälla.

Our history

From machines to solar roofs

Midsummer was founded in 2004 with the desire to transform the world's most climate-friendly energy source into usable energy for everyone.

The background of our founders is in the manufacture of machinery for CD readers and flat screen displays – a technology and production method that is very similar to the technology used in our solar cell manufacture.

Through a constant focus on further development and our vision of accelerating the transition to renewable energy, Midsummer has developed the most sustainable solar roof. Our products Midsummer SLIM, Midsummer WAVE and Midsummer BOLD are currently our main focus and sales area, while we continue to supply advanced production systems. Midsummer SLIM, Midsummer WAVE and Midsummer BOLD are today Midsummer's main focus and sales area, while we continue to deliver advanced production systems.

Our vision

With the most sustainable solar panel we transform the conventional roof and accelerate the transition towards renewable energy

Hållbarhet

With a clear focus on sustainability

Sustainability is at the core of Midsummer, and this is something that permeates throughout all levels of the organisation. Midsummer’s sustainability efforts are based on our desire to reduce the environmental impact of the production of solar roofs. A third-party-reviewed lifecycle analysis shows that Midsummer’s solar roofs generate almost 90% lower carbon footprints than traditional solar panels thanks to our efficient production systems. We’re extremely proud of being part of the global switch to renewable energy.

How do we achieve this? The solar panels are manufactured in our own production facility in Järfälla, which is powered by 100% renewable energy. The solar panels do not contain any heavy glass or aluminium element, significantly reducing materials consumption. In addition, the light-absorbent CIGS layer is extremely thin, contributing to a fast production process. However, we’re not stopping there, working every day to improve our products, processes and CO2 emissions.

Want to join us on a journey where no ideas are too big?

Then you’ve come to the right place! We are constantly looking for dedicated people with an interest in innovative technology, solar energy and stylish design.
