Photovoltaic Cladding

LafargeHolcim remains committed to an environmental approach and offers you the possibility of making your facades active using large-format DuctalⓇ panels (1,200 x 3,600 mm) that incorporate a photovoltaic film.

 

Using the new thin organic film technology developed by the German company Heliatek, the LCR, our research centre, is innovating and anticipating requests related to future thermal regulations.

Find out how DuctalⓇ concrete combines aesthetics and sustainability in local power generation management.

So why install a DuctalⓇ cladding photovoltaic panel on a facade?

  • In France and for countries situated above the 30th parallel north, DuctalⓇ photovoltaic cladding stands out by generating electricity in the early morning and late afternoon, thereby reducing the gap between generation time and consumption time, which has a direct impact on the sizing of electricity storage systems.
  • DuctalⓇ photovoltaic cladding also provides peak electricity generation in the spring and the autumn, when traditional rooftop photovoltaic solutions are characterised by a very low yield.
 

 

The graph below highlights the complementarity of a traditional rooftop photovoltaic solution, which is efficient during the summer, and a facade-mounted DuctalⓇ photovoltaic cladding solution, which performs well during inter-season periods, thereby enabling an increase in the electricity generation range that is more evenly distributed across the year.

The higher your building, the more the facade surface area available is greater than that of the rooftop:

  • 2-storey building: ~ 500m² on the rooftop and 900m² on the facades
  • 5-storey building: ~ 500m² on the rooftop and 1,700m² on the facades
  • 8-storey building: ~ 500m² on the rooftop and 2,600m² on the facades

* For the photovoltaic option for a DuctalⓇ cladding panel facade, 60% of which is covered using the OPV Heliatek technology, installed on a 5-storey building.

By 2020, we should be able to half the cost of this solution, in order to enable a return on investment of between three and five years.
