Project Address

Product Type

Lumina Slate Series

Complex Roof Geometry & Obstacles: The villa features a highly sophisticated multi-hip roof design, punctuated by chimneys and large skylights. Traditional rectangular solar panels cannot efficiently cover these irregular trapezoidal roof faces without leaving awkward gaps and wasting valuable space.
Aesthetic Preservation: Located in a high-end residential community, the client demanded a 13kW high-capacity solar system but absolutely refused the visually disruptive, bulky metal frames of traditional BAPV systems.

Edge-to-Edge Modular Fit: We deployed the Lumina Slate (Pro+) series. Its modular design and custom flashing allowed our installation team to navigate seamlessly around the chimneys and skylights. By covering the irregular facets edge-to-edge, we maximized the active roof area to 255 sq.m.
The Invisible Solar Roof: The finished roof maintains a sleek, modern, flush aesthetic that perfectly matches the villa’s high-end architectural style, while seamlessly generating 15,600 kWh annually.
