Gasthaus Siehen in Eggiwil

The Gasthaus Siehen is idyllically nestled in the Eggiwil countryside. It was important to the client to have an elegant, full-surface covering of the building at an optimal price-performance ratio.

The Solution

What is the Solution?

The LEVEL roof-integrated system consists of glass-glass solar modules that are overlapped – just like roofing shingles. Even complex surfaces can be covered, which makes it the perfect solution for entire and aesthetic roof integrations.

Why Does it work?

Aesthetically attractive integration solution for applications with standard-size, black modules. Offers an excellent balance between aesthetics, cost and performance.

PROS

Integration quality
Adaptability to all surfaces
Good finish with dummy modules
Good aesthetic-cost-performance ratio

CONS

Black modules not always suited to demanding heritage constraints.
