Sika adhesive technologies enables the Photovoltaic, Concentrated Solar Power and Solar Thermal system providers to reach for new design options and cost reduction thanks to material savings as well as improved processes.

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.
