Building-Integrated Photovoltaics (BIPV)

Detailed overview of innovation with sample startups and prominent university research

What it is

Building-integrated photovoltaics (BIPV) integrates solar panels into building materials, such as roof tiles, windows, and facades. This allows buildings to generate electricity from their own surfaces, reducing reliance on the grid and contributing to a more sustainable built environment.

Impact on climate action

Building-integrated photovoltaics (BIPV) within Distributed Solar PV enhance climate action by seamlessly integrating solar panels into building structures. By maximizing solar energy generation potential in urban areas, BIPV reduces reliance on fossil fuels, mitigates carbon emissions, and accelerates the transition to renewable energy, combating climate change.
