Swedish-made solar panels for companies

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.  

• 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%.
