Midsummer 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.
No, 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 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.
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.
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.

A solar panel consists of a variety of materials and most of them we buy from reputable American, Japanese and European companies. The solar cell, which is the main component of the solar panels, has a light-absorbing layer that mainly consists of copper, indium, gallium and selenium. These input materials are purchased from selected suppliers in Japan, Austria and the USA, among others.
The silver on the front of the solar cell is purchased from companies in England and the USA. We have visited and worked closely with all of these companies that we work with for over 10 years. The materials we encapsulate the cell with are purchased from the USA, Japan and Italy. We have also visited these companies.
A solar panel consists of a variety of materials and most of them we buy from reputable American, Japanese and European companies. We do not use a component from China, but some material suppliers refine ultra-pure powder in China (eg purified copper from Zhejiang province, purified selenium from Guangdong and purified sulfur from Sichuan. Midsummer has both reviewed and made physical visits to these suppliers. Midsummer uses no material from Xinijang (as the report on Swedish Radio applied). All suppliers have signed the Midsummer Code of Conduct.
A solar panel consists of a variety of materials and Midsummer buys most of the materials from reputable American, Japanese and European companies. We assess that the risk of child or forced labor in these countries is very low.
Some of the materials where one could suspect that there is an increased risk are, for example, the powder raw materials used in part of our manufacturing process for the solar cells. For example Molybdenum (Mo) and Wolfram (W). As for W and Mo, our supplier buys it from its wholly owned American subsidiary "Global Tungsten & Powders". They also recover a lot of Wolfram from scrap.
Global Tungsten & Powders follows the "Responsible Minerals Initiative" (RMI) and is checked annually by RMI. The standard is called "Responsible Minerals Assurance Process". They are listed on RMI's website as an RMAP conformant company http://www.responsiblemineralsinitiative.org/conformant.../. Global Tungsten & Powders har produktion i USA, Tjeckien och Finland. De har nyligen investerat utvinning av Wolfram i Korea.
Yes, our solar roofs are certified according to IEC 61215 and IEC 61730 by TÜV.
Ja, våra solcellstak är certifierade av TÜV. De har testats i klimatkammare, thermal cycling, snötryck, hagel osv. enligt gällande standarder. Våra solcellstak klarar alla tester över standard och framför allt snötryck klarar våra paneler långt mer än vad tex TÜV klarar av att utsätta dem för. Dessutom har vi en mängd installationer på tak i klimat med snö och is, de flesta i Sverige bl.a. i Nordingrå.
