The ultimate synergy between photovoltaic panels and sedum green roofs. Natural plant transpiration cools solar panels, boosting electricity yields by up to 15% without any roof penetrations.
Evapotranspiration Prevents Solar Panel Overheating
Photovoltaic panels lose roughly 0.4% efficiency per degree above 25 °C. Living sedum foliage continuously evaporates moisture, maintaining an optimal thermal microclimate for superior energy harvesting.
ZERO DRILLING PENETRATIONS
100% Non-Penetrating Ballast Anchoring
Mounting frames click securely into broad drainage baseplates held down by the combined deadweight of the substrate and sedum blanket, guaranteeing permanent leak-free waterproofing integrity.
MAXIMUM ROOFTOP ROI & ESG IMPACT
Dual Functionality: Clean Energy and Stormwater Detention Combined
Property developers previously had to choose between clean energy generation and municipal stormwater detention. Biosolar unifies both functions, maximizing return on investment, reducing building cooling demands, and achieving premier BREEAM, LEED, and ESG certifications.

Frequently Asked Questions
Engineering guidelines on energy output calculations, ballast security, and maintenance.
Conventional dark bitumen or metal roof surfaces reach 70 to 80 °C in summer heat, reducing photovoltaic cell efficiency by ~0.4% per degree above 25 °C. The vegetation layer continuously transpires moisture, stabilizing ambient rooftop temperatures at 30 to 35 °C and boosting electrical output by 6% to 15%.
No, the Biosolar assembly requires zero screw penetrations through the waterproofing barrier. The PV subframe locks directly into wide drainage baseplates, anchored solely by the structural ballast weight of the mineral substrate and sedum blanket.
Our Biosolar layouts utilize specialized dwarf sedum cultivars that grow to a maximum height of 5 to 10 cm. Subframes elevate module front edges 20 to 30 cm above the substrate line, completely eliminating botanical shading risks.
Biosolar delivers multiple credits simultaneously across on-site renewable energy generation, stormwater retention, and local ecosystem restoration, accelerating ESG targets for institutional portfolios.
