Why Midsummer?

Swedish

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

Sustainable

Midsummer's solar roofs have 90% lower than traditional solar panels. 

Unique

Midsummer solar panels are flexible and only 2 mm thin, with a minimum weight of about 3 kg / m² (excl. roof). No drilling is required during installation and the solar roof can be carefully walked on during maintenance.

Discreet

With Midsummer's discreet solar roofs, you can produce solar without changing the house's original design.

Safe

We are experts in solar roofs and will be with you throughout – from initial contact to final installation. Midsummer's solar roofs has a 10-year product guarantee and 90% expected peak power after 10 years and 80% after 25 years.

“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

Describe your roof and what you want – our solar roof designers will design an individual solution for your roof. We offer turnkey contracts.

02

Estimates

When you have chosen the solar roof that suits you, Midsummer prepares a quote. After reaching an agreement, we will make a site visit to confirm the roof’s dimensions.

03

Financing with a green loan

In collaboration with Hemma and Skandiabanken, we offer the opportunity to finance your solar cells through a loan with a green discount. Read more here.

04

Tillverkning och installation

Efter kontrollmätning tillverkas dina solpaneler i vår produktionsanläggning i Järfälla utanför Stockholm. När materialet är färdigt utför våra certifierade installatörer och elektriker installationen enligt branschstandard. 

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

Ditt solcellstak kan nu producera el av solens strålar för eget bruk eller försäljning till elnät. Midsummer's solar roofs has a 10-year product guarantee and 90% expected peak power after 10 years and 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

Den el som dina solceller producerar kan du antingen förbruka själv eller mata in på elnätet. Den el du inte använder levereras automatiskt ut på elnätet. Detta kallas överskottsel och den kan du sälja till ett elhandelsföretag.

A sunshine story all over Sweden

Midsummer installs solar roofs all over Sweden, on the pins on the map you can see a selection of where in the country our solar roofs are located. Click on the pin for more information.

Midsummer's solar panels consist of thin-film solar cells of the CIGS type, which makes them thin, light, flexible and discreet. The solar panels are placed on different types of roofing material, e.g. sheet metal, roof tiles or roofing felt, where the end product becomes a discreet solar roof.

The solar cells are manufactured in our production facility in Järfälla with our own DUO system, which is the most widespread production system for flexible CIGS solar cells in the world. The solar cells are then assembled into finished solar panels, also in Järfälla. The solar panels are placed on different types of roofing material, e.g. sheet metal, roof tiles or roofing felt, where the end product becomes a discreet solar roof.

  • Our products are manufactured at our own production facilities in Järfälla outside Stockholm.
  • The manufacture of Midsummer's solar roofs 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. The result is a discreet solar roof.

Midsummer's solar roofs are suitable for most roofing materials, such as private houses, 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%.
