Project Overview

A luxury villa in the prestigious Yunxi Diegu residential community in Hangzhou, subject to strict HOA aesthetic standards. The project demonstrates Lumina Slate's ability to satisfy community architectural guidelines while delivering an 8 kW invisible solar system on a complex multi-hip roof.

Project Challenge

Situated in the highly sought-after Yunxi Diegu residential community, this villa is subject to strict community architectural guidelines. Traditional rack-mounted solar panels were deemed too industrial and visually disruptive. The 163 sq.m roof features a multi-hip design with several converging slopes and small ventilation chimneys.

Sunlit Solution

We installed the Lumina Slate (Pro) series to serve as both the primary roofing material and the power generator. The sleek, dark flat profile mimics high-end traditional slate, instantly satisfying community aesthetic standards. Our custom edge flashing and modular tiles allowed the installation team to effortlessly navigate the complex multi-hip structure. The resulting 8 kW system is entirely invisible, safely generating 9,600 kWh of clean energy annually.

Architectural Outcome

The dark, flat solar-tile profile follows the villa’s converging multi-hip slopes and ventilation chimneys, with project-record edge detailing at the roof perimeter.
