Expanding Solar Energy Opportunities: From Rooftops to Building Integration


When it comes to generating solar energy on buildings, the typical image that comes to mind for most people is rooftop solar panels—those neat rectangular glass modules sitting atop homes. However, solar technologies encompass more than just rooftop panels. Building-integrated photovoltaics (BIPV) revolutionize this concept by integrating solar panels directly into various parts of a building’s structure, such as the roof, skylights, balustrades, awnings, facades, or windows. Carports or parking shade structures with built-in PV panels are among the most common forms of BIPV.

BIPV offers numerous advantages over traditional rooftop panels. By generating clean energy onsite, solar power provides certainty about the source of energy, reduces electricity bills, and enhances grid resilience and reliability. In situations where rooftop installations are impractical, such as due to homeowner association rules, roof weight limitations, or building design constraints, BIPV provides viable alternatives like solar facades, parking structures, or awnings. Moreover, BIPV not only contributes to environmental sustainability but also offers aesthetically pleasing and space-saving solutions for transitioning to renewable energy.

The U.S. Department of Energy (DOE) Solar Energy Technologies Office (SETO) is actively working to explore the opportunities and address the challenges of BIPV technology. Through initiatives like the BIPV Request for Information (RFI) and workshops, DOE engages stakeholders to identify opportunities for advancing BIPV systems. Funding opportunities such as the Dual-use Photovoltaics Incubator aim to develop products that can open new markets for emerging dual-use PV sectors like BIPV. Collaborative projects with organizations like the Architectural Solar Association and the National Renewable Energy Laboratory (NREL) are focused on developing educational programs covering various aspects of integrating solar technology into the built environment.

BIPV represents an emerging sector in solar energy with the potential to offer significant benefits to consumers. From agrivoltaics to floatovoltaics and solar photovoltaic and thermal technology (PVT), the diversity of solar energy applications continues to expand. DOE remains committed to further research in BIPV and other dual-use technologies to support U.S. solar manufacturing, foster innovation, and address barriers to equitable solar energy deployment.

For those seeking more information on BIPV and other dual-use PV sectors, resources provided by SETO offer valuable insights into ongoing research and market trends.
