What is the Solution?

Roof-integrated photovoltaic solar modules (the solar system acts as a roof covering). Black colour for maximum performance. Satin-finish glass for glare-free elegance and a harmonious interplay of light and shadow.

Why Does it work?

The best compromise between performance and aesthetics. Optimum architectural integration, respecting the architectural and heritage aspects of the building and area. Solution adapted to demanding climatic conditions (today's most demanding standards in terms of weather resistance).

PROS
  • Maximum ratio of performance to aesthetics
  • Meets the most demanding standards
  • Adaptable to building and site requirements (colour, texture, shape)
CONS
  • Lower energy performance than standard modules.
  • Higher costs than a standard solution.
  • More demanding to implement.
