Why choose Midsummer?
Swedish Developed
Midsummer’s solar cells are a Swedish innovation and are manufactured both in Sweden and Italy.
Minimal weight
With a minimal weight of only 3kg per square meter, our solar cells enable installation on roofs with weight restrictions without compromising the structural integrity of the roof.
Sustainable
Recyclable
Our silicon-free solar cells are not only 98% recyclable but also include 63% of materials from reuse, strengthening our contribution to a more sustainable future.
Efficient installation
Our solar panels offer easy and secure mounting without penetrating the roof’s waterproof membrane, enabling an installation speed that is 50% faster than traditional solar panels.
Easy maintenance
Our solar panels are designed for easy maintenance, allowing for maximum use of roof space. They are durable enough to walk on and are adapted for activities such as snow removal, making them a practical and sustainable choice for all types of climates.
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.
Our solar cells are manufactured at our production facilities in Järfälla, Sweden, and Bari, Italy, using our proprietary DUO system, the world’s most prevalent production system for flexible CIGS solar cells. After manufacturing, the solar cells are assembled into complete solar panels at the same locations. Our solar panels are designed to be compatible with various roofing materials, including metal, tiles, and felt, creating a sustainable and aesthetic solar roof.
For our Midsummer BOLD-S model, we collaborate with OEM manufacturers in Asia to satisfy global demand and ensure high production quality and efficiency.
- Our products are manufactured in our own facilities in Järfälla outside Stockholm and in Bari, Italy. For our model Midsummer BOLD-S, we also cooperate with OEM manufacturers in Asia.
- 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.
We offer three specially tailored products for different types of roofing materials, including tiles, metal, bitumen, and PVC.
Midsummer WAVE is a solar panel that is placed on top of double-curved tiles from well-known manufacturers such as Benders (Palema), Monier (Jönåker), and S Eriks (Mjöbäck and Ekeby). These can be installed either during retrofitting or during a complete roof replacement.
Midsummer SLIM modules are available for both combined purchases with seamed metal roofs and for retrofitting on existing seamed metal roofs.
Midsummer BOLD modules are designed for both flat and sloped roofs and are suitable for substrates such as bitumen, plastic membranes, and PVC.
Our solar panels are ideal for installation on private villas, apartment buildings, and industrial buildings.
Yes, all our products are suitable for retrofitting. The installation is simple and does not affect the roof’s waterproofing layer.
Midsummer WAVE is installed directly on top of the roof tiles. The panels are attached under the row of tiles above and secured with clips at the bottom.
Midsummer BOLD modules are attached with double-sided butyl tape directly to various roofing materials such as felt and membrane roofs. For PVC roofs and other special materials, we offer customized installation methods that optimize both safety and durability.
Midsummer SLIM modules are mounted with double-sided butyl tape on seamed metal roofs.
