New Joining Techniques for Solar Energy
Market conditions put high pressure on cost structures, while demanding top quality and long-term performance of Solar Energy system.
The industry is therefore forced to consider optimizations in production and installation processes as well as new innovative designs. This leads to new materials and joining techniques which have to be implemented into production and installation.
The appropriate adhesive technology enables to save cost, increase production efficiency and even allows to add unique features to the final Solar system.Sika assists you with comprehensive project support in all phases from design to implementation and after-sales service with the optimal solution to achieve your targets.
Concentrated Solar Power
Mirror Bonding
Bonding the mirror to the specific mounting systems as heliostats in tower, parabolic trough or fresnel technology.
System Benefits
- Proven in several CSP plants around the world
- Long term performance under harsh environmental conditions
- Enabling a lean and cost enhanced design and production
Solar Thermal Collector
Bottom plate bonding
Bonding and sealing of bottom plate to framing system
System Benefits
- Shortens cycle times with faster curing technologies
- Reduces handling times thanks to increased initial strength
- Secures joint performance with structural adhesives
Cover Glass Bonding
Bonding and sealing of cover glass to the framing system
System Benefits
- Eliminates mechanical fixing of cover glass
- Secures durability and tightness thanks to the structural adhesive
- Increases the production output
- Simplifies automation of production
- May eliminates raised edges that trap dirt or water
Thinfilm Photovoltaic
Bonding to mounting devices
Structural bonding of the module to the mounting structure in production or on-site
System Benefits
- Saves up to 40% installation time
- Saves up to 25% overall PV system cost
- Elimination of electrical grounding
- Minimized material handling compared to clamping
- Minimized micro cracks on cells implies higher yield
