Building-Integrated Photovoltaics (BIPV) combines solar power generation with architectural function, integrating PV modules directly into a building's structure—such as its façade, roof, or skylight. BIPV systems not only produce clean energy but also serve as part of the building envelope, replacing conventional materials. However, the installation process is quite different from that of traditional solar panels and involves several specialized steps.

1. Initial Planning and Design

The first phase of a BIPV project involves careful planning and coordination between architects, engineers, and solar specialists. Factors such as the building’s orientation, local climate, expected energy output, and design aesthetics are reviewed.

Unlike traditional solar systems that are mounted on top of existing surfaces, BIPV modules must be integrated into the original construction or renovation plan. This means that every element—from module shape to electrical routing—must be customized. Specialized mounting structures are often required to ensure that the modules blend seamlessly into the design without compromising safety or performance.

Manufacturers like SIC Solar, which focus on producing and supplying PV mounting structures, often collaborate with project designers early in the process. Their mounting systems are designed to be adaptable to the custom requirements of BIPV applications, especially in roof and façade integration.

2. Structural and Electrical Preparation

Before any components are installed, the building’s structural frame must be evaluated to confirm its ability to support the weight and load of BIPV modules. At the same time, provisions for wiring, inverters, and connection to the electrical grid must be made.

For façade-mounted systems, frames and anchors are embedded into the wall structure. For BIPV roofs, waterproofing becomes a critical focus, as the modules serve as part of the roofing material itself. Proper drainage, insulation, and vapor barriers are key to a durable installation.

Mounting suppliers like SIC Solar provide tailored solutions that meet structural codes while also ensuring ease of assembly. Pre-assembled bracket components can shorten installation time and help prevent errors on site.

3. Mounting System Installation

The substructure installation begins once all preparations are complete. This system is responsible for supporting the BIPV modules, ensuring structural integrity, and maintaining proper alignment.

Rail systems, clamping devices, and joint seals must be positioned with precision. Tolerances are often tighter in BIPV than in conventional systems, as the modules form part of the visible building surface. Even slight misalignments can affect both energy performance and visual appeal.

In many projects, stainless steel or aluminum alloy brackets are preferred due to their strength and resistance to corrosion. SIC Solar offers a variety of these materials, catering to both sloped and vertical BIPV systems.

4. Module Installation and Electrical Work

Once the racking system is in place, the BIPV modules are installed according to the building’s layout. Transparent or semi-transparent modules may be used in skylights or curtain walls, while opaque ones are applied to walls and roofs.

Each module must be carefully connected using weather-resistant connectors. Junction boxes and DC cables are routed through the mounting system to maintain a clean appearance. Electrical insulation, grounding, and fire safety standards must be strictly .

Because the modules serve dual roles—as energy generators and building materials—additional care is required during handling and placement. Many installers rely on detailed installation manuals provided by mounting system manufacturers, such as those from SIC Solar, to ensure safety and accuracy.

5. System Commissioning

After installation, the system undergoes testing to verify that all connections are secure and that performance is within expected parameters. IV curve tests, insulation checks, and performance monitoring are carried out before the system is officially connected to the grid.

Building-integrated systems often include monitoring equipment that tracks energy production and system health in real time. These tools help building owners ensure optimal performance while also detecting potential issues early.
