What is Building Integrated Photovoltaics?
Building integrated photovoltaics (BIPV) refers to solar technologies integrated directly into the building envelope, such as facades, roofs, and windows, instead of being mounted separately. Unlike conventional rooftop panels, BIPV systems serve as both building materials and energy generating devices. This dual function helps architects and developers maintain aesthetic appeal while reducing a structure’s carbon footprint. BIPV products include modules designed for installation as curtain walls, roofing tiles, skylights, canopies, and more.
Benefits of BIPV for Commercial Buildings
BIPV offers a host of advantages for commercial property owners and facility managers. Here are some of the biggest benefits:
- Energy Savings: Generating renewable electricity on site can significantly lower operational energy costs.
- Architectural Flexibility: Modern BIPV products come in various colors, shapes, and transparencies, supporting creative design concepts.
- LEED and Green Certification: Integration with BIPV systems can help projects earn points toward LEED and other sustainability certifications.
- Durability and Protection: Many BIPV materials replace traditional building envelopes, providing weather protection, sound insulation, and UV resistance.
- Increased Property Value: Sustainable buildings with lower operating costs and modern design tend to attract premium tenants and buyers.
- Regulatory Incentives: Government programs often provide tax credits, rebates, and fast tracked permitting for solar embedded projects.
Choosing BIPV is not just about meeting regulations it is a strategic investment in your property’s efficiency and competitiveness.
Types of BIPV Products Used in Commercial Buildings
BIPV solutions have evolved dramatically over the last decade. Today, commercial buildings can choose from a wide range of options that blend seamlessly with diverse architectural styles. Below are the main types of BIPV products used in commercial construction:
1. BIPV Roof Shingles and Tiles
These products substitute standard roofing materials with photovoltaic systems, combining weatherproof protection and solar generation. Key examples include solar roofing tiles, flexible solar membranes for flat roofs, and semi transparent skylight modules.
2. BIPV Facade Panels and Curtain Walls
BIPV curtain walls and facade modules are specially designed to replace traditional glass or cladding with energy producing panels. They are ideal for high rise office buildings, retail complexes, and hospitality venues seeking a striking visual statement.
3. Solar Windows and Glazing
Photovoltaic glass uses advanced transparent solar cells that are embedded within window glazing. These allow natural daylight while generating electricity, making them perfect for atriums, skylights, and south facing windows in sunny climates.
4. Canopies and Sunshades
Covered walkways, entrance canopies, and shading devices can all be equipped with BIPV modules. These additions boost occupant comfort and energy output without affecting usable real estate inside the building.

Key Factors in Choosing BIPV Products
Selecting the right BIPV solution for a commercial project requires careful consideration of multiple variables. Here are the top factors property developers should evaluate:
- Performance and Efficiency: Compare products based on their module efficiency, annual power yield, and performance in specific climate zones.
- Transparency and Aesthetics: For visible applications like windows and facades, choose BIPV modules offering compatible glass tints, color options, or desired transparency levels.
- Durability and Certifications: Confirm that chosen modules carry appropriate certifications (UL, IEC, etc) and are rated for wind load, impact resistance, and fire safety.
- Integration Compatibility: Consult with structural engineers and architects to ensure the system integrates with current building materials and design parameters.
- Warranty and Support: Investigate product warranty terms, access to technical support, and the manufacturer’s track record for reliability.
- Cost and Return on Investment: While BIPV systems often involve higher upfront costs than standard PV, the additional value in aesthetics, insulation, and space saving can make projects cost effective over their lifespan.
Engage with technical consultants early in the planning stage to identify any local code requirements or integration challenges in your jurisdiction.
Integration Examples and Case Studies
The best way to appreciate BIPV’s impact is to see it in action. Here are a few notable examples of commercial buildings that have successfully implemented BIPV solutions:
1. Swatch Group Headquarters, Switzerland
This headquarters features a curved facade composed of custom photovoltaic glass elements by Ertex Solar. The integration yields a net positive energy building, helping the company achieve its ambitious sustainability targets.
2. The Walt Disney Company Headquarters, California
The Walt Disney Company Headquarters in California showcases BIPV integration through its solar window installations, supplied by Onyx Solar. These installations not only generate clean electricity but also provide enhanced daylighting and improve the energy efficiency of interior spaces.
