Sika SolaRoof® SYSTEMS FOR SOLAR ROOFTOP APPLICATIONS

The great opportunity, of using flat rooftops for solar applications was recognized early by Sika. The first photovoltaic (PV) installations on Sarnafil® membranes date back to 2004. Several development steps led to the current Sika® SolarMount-1 (SSM1)system. SSM1 requires no roof penetrations but is hot-air welded to the Sika membrane, which prevents lateral movement ofthe PV plant on the roof over time.

The PV panels on SSM1 can be oriented south or east-west with same SSM1 components. Sika maintains its own solar parks in several locations to:́́

  • Monitor the energy yield of different PV technologies
  • Collect first-hand experience with long-term performance
  • Showcase the flexibility of Sika roofing solutions for PV applications

Electricity production on the roof vs. personal consumption

The electricity demand on a typical weekday is represented by the blue curve. The energy produced is represented by the yellow (sunny summer day) and the gray curve (partly cloudy day).

More Value

  • Customer: International retail chain with a predictable energy load progression.
  • Projects: New buildings or stores with a refurbished flat roof.
  • Requirements: The customer expects a high energy self-consumption rate thanks to the PV plant on the rooftop.
  • Sika Solution: Durable roof buildup with thermoplastic reflective Sarnafil® TS-77 RAL 9016 SR / Sikatherm® PIR roofing system and Sika’s PV system Sika® SolarMount-1.
  • Sika Sustainability Approach: Custom project-specific LCA report including calculation of carbon emissions savings. A selfconsumption rate of 80 – 90% was reached.
