What is a
Biosolar Roof?
Explore expert BioSolar guidance covering design, installation, maintenance and best practice to help you deliver efficient, compliant and long-lasting commercial systems.
WHAT IS A BIOSOLAR ROOF
A biosolar roof is a roof where solar PV and a vegetated roof build-up are planned as one coordinated solution.
Instead of being added independently, both parts are designed to support each other’s performance.

WHY BIOSOLAR ROOFS DELIVER MORE VALUE
Biosolar roofs combine solar PV and green roofs as one coordinated system to deliver multiple benefits from the same roof space.
Flexible for different
goals
A biosolar roof can be designed to suit different project priorities, like boosting biodiversity, improving thermal performance, or increasing renewable energy generation.

The system still
works the same way
Even though layouts can vary, the key principle stays consistent: the green roof supports the solar, and the solar supports the green roof.

A stronger rooftop
environment
By working together, planting and PV can create a more diverse, stable, and resilient rooftop environment compared to treating them as separate systems.

Protects the
building
A biosolar roof helps protect the roof membrane from UV exposure and weathering, reducing wear over time and supporting a longer-lasting roofing system.

As cities push for smarter use of space and stronger sustainability outcomes, biosolar roofs are becoming a key solution for delivering multiple benefits in one footprint.
