BauderSOLAR PV System

The BauderSOLAR photovoltaic (PV) solution for flat roofs features the integrated system in which the solar PV module and the substructure are combined to form a single unit, which is secured to the roof without any penetration of the waterproofing or roof deck. This ensures that the integrity of the roof is upheld throughout the installation of the PV array. The system is designed to be used in conjunction with Bauder single ply or bituminous membranes and is extremely lightweight at 9-12.5 Kg/m², depending on module selected.

Key features

  • Risk-free, zero penetration installation•  Single source for integrated design of waterproofing and PV
  • Weighs just 9-12.5kg/sqm 
  • Range of modules delivering up to 455w per panel
  • Panels designed to create a 12º angle


  • Integrity of waterproofing upheld as a result of drill-free installation
  • Welded installations are considerably lighter than ballasted solutions - most ballasted systems weigh at least 25kg/sqm
  • Full guarantee covering waterproofing, PV components, modules and installation
  • High energy generation with minimum 16.82% panel efficiency
  • Lightweight panels are quick and easy to install, making it a cost-effective solution.
  • Low angle makes for optimum energy generation and easier to overcome planning issues
  • Maintenance of the waterproofing membrane is very easy as individual panels can be removed if required.

Our combined solar array and waterproofing offer provides a single-source solution with clear accountability to reduce risk and bring peace of mind through all aspects of the flat roof. The BauderSOLAR solution utilises high efficiency JA Solar and Aleo Solar modules with a range of panel options to suit client needs and budget.

Environmental credentials

Renewable energies, such as solar PV, are derived from natural processes that are replenished constantly and are therefore becoming increasingly important. A combination of the environmental impacts associated with burning fossil fuels and the spiralling costs of energy are driving a focus towards dealing with climate change by increasing renewable energy usage.

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 rooftop solar panels are installed at the optimal angle for maximising energy generation from each flat roof, delivering market leading efficiences to meet all requirements. The lightweight integrated system is backed up by a comprehensive guarantee as standard, covering the waterproofing, module components and PV installation. The modules are easily maintained, as highlighted in our system maintenance advice guide.


Your project is important to us and our service is dedicated to providing a photovoltaic solution that fully understands all the individual issues of the project and answers the waterproofing needs of the building, as well as any green roof requirements. We offer a 6 step turnkey service which includes a brief and consultation, design and specification service, grid connections and funding options, contractor selection, sign off and guarantee, and monitoring and maintenance.
