Bauder BioSOLAR - Integrated Solution

Our BioSOLAR system is an integrated solution for mounting photovoltaic renewable energy on a green roof or a blue roof where the substrate and vegetation provide the ballasted installation mechanism to secure the array. The system is suitable for both new build construction and retrofit projects.

This system allows for the entire roof area to qualify as a green roof, and if a biodiversity vegetation finish is elected for, this can further enhance the BREEAM credit rating for the roof element.


Key Features

  • No roof penetrations as substrate and vegetation ballast the PV array.
  • Maximises solar output and allows entire roof to qualify as biodiverse green roof.
  • Maximises solar energy generation as green roof preserves ambient rooftop temperatures, keeping the modules at optimal output. The cooling effect increases panel output by up to 5%.
  • Raised modules allow light and moisture under the panels and the creation of a variety of habitats supporting a greater range of plant species and small invertebrates.
  • Single point responsibility for the waterproofing, green roof and PV installation.
  • Increased module space between substrate and panels reduce risk of panel damage during green roof maintenance.

Benefits of a BioSolar system

  • Where a green roof and solar are required BioSolar allows the whole roof area to be vegetated as well as maximising PV output.
  • Allows easy maintenance beneath front end of modules where vegetation is likely to be strongest and cause shading.
  • The Flora 3 seedmix is specifically designed to work beneath the PV modules.
  • A cost-effective solution when comparing against mechanically fixed installations.
  • No additional ballast needed.

Installation and maintenance

The quality and experience of the installing operative is paramount to ensuring a successful project. Bauder Approved Contractors are the only people fully trained and certified to install our products. They provide the necessary experience that our exceptional guarantee demands.

The construction and development of buildings in today’s market is calling for rooftop solutions that include a duality of technologies for environmental advantage; a biodiverse green roof coupled with ecological and SuDS enhancement and a solar photovoltaic array. Bauder embraces this cohesive stance with our BioSOLAR solution designed to meet planning and BREEAM requirements.
