Why Midsummer?

Swedish

Midsummer solar panels are a Swedish innovation, manufactured at the Midsummer production facility in Järfälla outside Stockholm.

Sustainable

Midsummer solar panels have a carbon footprint almost 90% lower than traditional solar panels.

Safe

We are solar panel experts and will be with you throughout – from initial contact to final installation.

Aesthetic

With Midsummer's discreetly designed solar panels, you can produce clean electricity and improve the aesthetics of your house.

Unique

Midsummer solar panels are flexible and only 2 mm thick, with a weight of 3 kg/m². They do not require any holes to be drilled during installation and the roof can be walked on during maintenance if done with care.

“A friend advised us to check out Midsummer. So we did, and quickly realised that it could work. Midsummer has clear advantages over other solutions, as it is made here in Sweden and extends over more of the roof.”

“I wanted a solution that suited our building without being too intrusive. I’m very happy with my roof, both in terms of its look and functionality, and working with Midsummer on the installation was quick and effortless.”

How it works

01

Guidance

Beskriv ditt tak och dina önskemål – våra solcellsprojektörer designar en lösning för just ditt tak. Vi erbjuder totalentreprenad.

02

Estimates

When you have chosen the right solar panels for your roof, Midsummer produces a cost proposal. After reaching an agreement, we will make a site visit to confirm the roof’s dimensions.

03

Manufacturing

After control measurement, your solar panels are manufactured in our production facility in Järfälla outside Stockholm.

04

Installation
Midsummer installers and certified electricians perform the installation in accordance with industry standards.

05

Commissioning

When installation is complete, we will help you to send in the final application to your electricity supplier. When the supplier has approved the final registration, we put the plant into operation and hand over all the necessary documentation so you can feel safe with your installation.

06

Electricity production
Your roof can now produce electricity from the sun's rays for your own use or to sell to the electricity grid. Midsummer solar panels have a ten-year product warranty and expected peak output of 80% after 25 years.

How solar energy works

Med PowerMesh Technology (PMT) får du nu en ännu mer diskret look utan vita linjer. Men det bästa är bevarat – du får samma svensktillverkade och pålitliga solpanel, lika enkel att installera och underhålla som förr.

How solar energy works

Climate change is one of the greatest challenges of our time, and it is more important than ever to recover energy from renewable sources. One of the greatest sources of energy is the sun. The sun produces as much energy in two hours as the combined annual consumption of the world's population.

But how do we exploit solar energy? And how does the process work, from the sun's rays shining on a solar cell to electricity in our sockets?

01

Where does it start?

Solar panels consist of a number of solar cells connected to each other in series. When the solar rays shine on the solar panel, electrical voltage is created between the front and back of each solar cell. This electrical voltage forms direct current.

02

From direct current to alternating current

The direct current is sent to an inverter installed in your house. The inverter converts the direct current to alternating current. The alternating current is sent in turn to your central electrical unit and on to the house's power sockets. 

03

Use your solar electricity

You can either use the electricity that your solar cells produce yourself or feed it back into the electricity grid. The electricity you do not use is automatically fed back into the grid. This is known as surplus electricity and you can sell it to an electricity company.

Midsummer's solar panels are made in Sweden from a thin film (CIGS = copper, indium, gallium and selenium) on stainless steel. This makes them thin, light and flexible. 

The solar cells are manufactured in our self developed DUO machine in our factory in Järfälla outside Stockholm. This is the key to our efficient production. The solar cells are then assembled into finished solar panels, also in Järfälla.
  • Our products are manufactured at our own production facilities in Järfälla outside Stockholm.
  • The manufacture of Midsummer solar panels produces 90% less carbon dioxide emissions than traditional solar panels, according to a third-party reviewed lifecycle analysis (LCA) carried out in 2020. 
  • The solar panels are light, flexible and only 2 mm thick, and do not affect the appearance of your roof or the aesthetics of your house. The roof still looks like a regular roof, even when Midsummer products have been installed.
  • The solar panels do not contain any heavy glass or aluminium element, significantly reducing materials consumption.
  • Installation does not require any holes in the waterproofing layer of the roof. We do not screw or drill holes in the waterproofing layer, significantly reducing the risk of leaks.

Our solar panels are mounted onto the surface, following the contours of the roof and are on top of the roof's waterproofing layer. In other words, they are integrated with the design, but not integrated technically, which means that they can be applied to existing building materials.

Midsummer solar panels are suitable for most roofs, such as rooftops, apartment buildings, industrial buildings and roofs with weight restrictions. 

Our product Midsummer SLIM is sold as a combination of a folded sheet metal roof and discreetly-designed solar panels. Our product Midsummer WAVE is suitable for 2-barrel roof tiles (Benders Palema and Monier Jönåker) and can be fitted on top of existing tiles or in the event of a replacement roof. Our product Midsummer BOLD is suitable for both flat and sloping roofs, for example with roofing felt and membrane as a base.

Yes, retrofitting is possible with both Midsummer WAVE and Midsummer BOLD . It involves a simple installation and does not damage the waterproofing layer of the roof. 

Midsummer WAVE is installed by placing it on top of the roof tiles and attaching it below a row of tiles and locking it in with clips at the bottom. Midsummer BOLD is attached with discreet sheet metal strips. These are screwed into plates which are then welded to the roof material, such as roofing felt or membrane roofs.

Midsummer SLIM is sold as a complete replacement roof.

Midsummer SLIM has an output of 111 W/m², Midsummer BOLD 116 W/m² and Midsummer WAVE 110 W/m². 

The thermal efficiency of our solar cells is 15-15.5%.
