“Bauder BioSOLAR PV Green Roof Systems” by Bauder, image/information source: Bauder
Bauder Mixed PV-Green Roof Systems integrate photovoltaic (PV) panels with biodiverse green roofs, using the roof substrate as ballast to avoid penetrating the waterproofing membrane.bauder+1
System Overview
Bauder’s BauderSOLAR G LIGHT is the primary solution for flat roofs, combining solar PV with extensive green roofs or blue roofs for stormwater management. The PV panels are elevated about 300 mm above the substrate, allowing light and moisture to reach vegetation underneath for optimal plant growth and panel efficiency.source.thenbs+1
Key Features
- Ballast-only installation via green roof substrate (e.g., BauderGREEN systems), compatible with slopes up to 5°.
- Supports shade-tolerant seed mixes like BauderGREEN Flora 3 BioSOLAR for areas under panels.
- Integrates with Bauder waterproofing (e.g., single-ply PVC or polyolefin) and SuDS-compliant blue roof voids.bauder+1
Applications
These systems suit new builds or retrofits, as seen in projects like Clapham Park (residential biosolar green roof) and the Catalyst Innovation Centre (with wildflower blankets). They meet UK standards like MCS PV Guide, GRO Biosolar guidance, and BREEAM/BAP biodiversity requirements.bauder+1
