Solenergi

Nya sammanfogningstekniker för solenergi

Marknadsförhållandena sätter högt tryck på kostnadsstrukturer, samt kräver toppkvalitet och långsiktig prestanda för solenergisystemet.

Branschen tvingas därför överväga optimeringar i produktions- och installationsprocesser samt nya innovativa lösningar. Detta leder till nya material och sammanfogningstekniker som måste implementeras i produktion och installation.

Den lämpliga självhäftande tekniken gör det möjligt att spara kostnader, öka produktionseffektiviteten och även lägga till unika funktioner i det slutliga solsystemet. Sika hjälper dig med omfattande projektstöd i alla faser från design till implementering och kundservice med optimal lösning för att uppnå dina mål.
