Lumina Slate Series

Maximized Capacity on a Traditional Profile: The client owned a sprawling luxury villa with a massive 266+ sq.m roof. The primary goal was to maximize the solar generating capacity (reaching 13kW) to cover high household energy demands, without resorting to ugly traditional solar racks that would ruin the neighborhood’s aesthetic.
Flawless Wire Management: With such a large-scale residential installation, ensuring structural waterproofing and safe, hidden electrical routing was a major concern for the client and the local building authorities.

Staggered Layout & Seamless Integration: We utilized the Lumina Slate (Pro+) series, employing a classic staggered installation pattern. This not only enhanced the modern architectural beauty—creating a stunning contrast with neighboring traditional roofs—but also optimized water runoff.
Engineered Beneath the Surface: As our installation logs show, the system features a robust structural batten framework and meticulous underlying DC wire management, ensuring that the 15,600 kWh annual generation is both completely invisible and exceptionally safe.
