The importance of rooftop solar applications was recognized early by Sika, because its Solar Reflective (SR) membranes can increase the performance of Photovoltaic (PV) panels.
Sika SolaRoof® Systems for Solar Rooftop Applications
The opportunity of using flat rooftops for solar applications was recognized early by Sika. The first photovoltaic (PV) in-stallations 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 of the 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
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.
