Midsummer BOLD

Solcellstak för bitumen- och plastmembran

Midsummer BOLD is an ultralight and flexible solar panel which, among other things, is intended for bitumen and plastic membrane as a base, where the end product becomes a discreet solar roof. Midsummer BOLD is developed for larger roof areas on commercial properties, industrial buildings, warehouses and sports arenas, but also apartment buildings and private homes.

Midsummer BOLD

Midsummer BOLD is sold as a complete replacement roof or can be retrofitted to an existing roof. The product acts as extra protection to the roof's waterproofing layer and stops UV light from damaging the waterproofing layer, increasing the roof's service life.

Its light weight makes Midsummer BOLD perfect for roofs with weight restrictions, such as on older buildings where the design is not as durable as modern roofs. 

Benefits of Midsummer BOLD


Midsummer BOLD är en svensk solcellsinnovation som tillverkas i vår produktionsanläggning i Järfälla utanför Stockholm.


Due to low material consumption, a unique manufacturing process and production in Sweden, Midsummer's solar roofs have a 90% lower carbon footprint compared to traditional solar panels.

Minimal weight

Minimal weight enables easy and safe installation without penetrating the waterproofing layer of the roof. High power of 39 W / kg, which is less than 30% of the weight for the same power for traditional solar panels.
