Can I retro fit Solar PV onto a Bauder roof?

Certainly, provided the building’s structure can accommodate the extra weight loadings. It’s crucial to verify that the anticipated lifespan of the existing or planned roof waterproofing system aligns with that of the PV array. Otherwise, the waterproofing system may need premature replacement. This would require removing the array before restoring the roof’s integrity. Ideally, integrating photovoltaics is most efficient when done concurrently with refurbishing the waterproofing system.

Bauder Green roof Solar Mounting

BauderSOLAR G LIGHT offers a solar PV mounting system. This system is designed for Bauder biodiverse or extensive green roofs.

The substrate and vegetation secure the array through ballasted installation. Suitable for both new construction and retrofit projects, Biosolar allows the entire roof area to qualify as a green roof. Opting for a bio system can further enhance the BREEAM credit rating for the roof element.

Key Features:

  • No roof penetrations, as substrate and vegetation act as ballast for the PV array.
  • Maximises solar output, enabling the entire roof to qualify as a biodiverse green roof.
  • Preserving ambient rooftop temperatures enhances solar energy generation. It optimises module output by up to 5%.
  • Raised modules provide space underneath for light and moisture. This fosters various habitats that support diverse plant species and small invertebrates.
  • Single point responsibility for waterproofing, green roof, and PV installation.
  • Increasing the space between the substrate and panels can prevent panel damage during green roof maintenance.

Bauder Roof Solar System Cost

Bauder’s mounting systems have a similar cost to other flat roof mounting manufacturers. However, they have the added advantage of being specially designed for Bauder roofs. Bauder guarantees the specified roof package. Additionally, they provide a single point of contact and responsibility. This minimises risk.

Compare Bauder Solar Mounting Systems

There are two main ways to secure a PV system to a flat roof: ballasted or mechanical. Ballasted systems, like Van Der Valk or Esdec, add weight to anchor the array. Adding weight to a structure requires confirmation from a structural engineer to accept the extra weight and wind load in the design. The ballast can have different forms, so it’s important to check that the static load matches the wind load calculation report.

There are two mechanical methods for roof installation. The first involves penetrating the roof covering with a Nicholson IFP and fixing it to the deck. The second method involves welding a base plate, like Bauder, while keeping the waterproofing system intact.

The Bauder system advantage is that it uses a mechanical fixing method. This makes it lighter than a ballasted system and doesn’t pierce the membrane.

Do you need to be Bauder approved?

Yes! Bauder don’t just focus on a single component— they guarantee the entire Bauder roof package. This approach offers a single point of contact and responsibility, minimising risks across the board. As a certified Bauder contractor, PV Plus are fully trained and certified to install Bauder Solar panel systems.
