1. Structural features

This system adopts point support installation method, and the solar panels are directly connected to the curtain wall columns through the four corners of the stainless steel connectors; 

The connectors are connected to the building structure through metal adapters, with flexible structure and small stress concentration. 

2. Key components and nodes

Stainless steel connectors: core components of this system, play a role in point connection and load-bearing; 

Curtain wall columns: the installation foundation of the connectors, which is set vertically in front of the structural beams to accept the weight of the panels and wind loads; 

Node detail ①: clearly shows the connection method of the connector, photovoltaic panel, column and concrete structure; 

Fireproof plugging: located between the photovoltaic module and the structure, plugging the gap to improve the fireproof integrity of the system;

1. System features

Each unit module is a self-contained system, which reduces the amount of on-site work, is quick to install and has high precision, and is suitable for super-high-rise or large-area curtain walls; 

Unlike the frame type or point-supported type, the unit type has completed most of the connections and commissioning in the factory, and only the structural installation and system docking are done on the construction site. 

2. Components and drawings

Main components:

solar panels: embedded in the curtain wall unit module, with a junction box; 

Glass: combined with solar panels to achieve partial lighting; 

Curtain wall columns/beams/connectors: constitute a unit frame structure and connect to the main structure; 

Junction box: located on the back of the photovoltaic module, used for system docking; 

Fireproof blocking: located at the junction of the module and the floor or structure; 

Reinforced concrete structural beams: provide fixing points for the curtain wall system.

Double-layer photovoltaic curtain wall installation diagram

This diagram shows the installation of a double-layer photovoltaic curtain wall system, which is suitable for energy-saving design schemes that use solar panels to replace part of the glass curtain wall materials on the building facade. The system is mainly composed of curtain wall beams, curtain wall columns, transparent glass, solar panels, structural beams, reinforced concrete main structure, ventilation ducts and fireproof blocking. The solar panels are installed between the columns and beams to form a stable, transparent curtain wall system with power generation function

Steel keel

Provides the main support frame for the installation of solar panels to ensure the strength and safety of the system. 

Design and construction precautions

The size of the solar panel (length L and width W) is determined by the designer based on the specific project requirements and site conditions. 

The specific practices of the awning are detailed in the engineering design plan and must be strictly implemented. 

The grid size and light transmittance of the solar panel must be determined by the designer based on the building function and aesthetic requirements. 

The installation angle α of the canopy solar panel is determined by the designer based on the local climate, lighting conditions and actual project conditions to ensure the best power generation efficiency and drainage performance。
