Closest to the sun.

Photovoltaic assemblies to turn solar energy into electrical energy and solar thermal modules place the highest demands on the sealant, glue and potting materials they use. For they are installed as much on storm-wracked coasts as in scorching deserts or on the roofs of huts at frosty alpine heights. There they are exposed without protection to extreme atmospheric influences, enormous temperature fluctuations, high wind loads, ice and brine.

At the same time, industrial production techniques are needed for the high volumes required to answer to the immense pressure on costs within the solar sector.

With Sonderhoff, the FIP(F)G processing specialist, machines, materials and process solutions are available, allowing you technical production advantages in this competitive industry. This goes for the production of solar thermal modules as well as for photovoltaic modules, their  connector boxes as well as for the power inverter unit housing and its contents.

With Sonderhoff to a sustainable future

Photovoltaic plants are designed for a lifespan of at least 15, often for more years. To guarantee suitably sustainable use and economical operation of these plants, all components must stand up to this timespan – a challenge many underestimate.

Sonderhoff with its material systems and more than 55 years’ experience can offer reliable solutions here – just ask us!

After installation, the PV modules and solar thermal modules must be so tight that moisture, dust, harmful media or temperature-induced influences do not stand a chance. Sonderhoff has the right sealing systems for this! PV inverter housings are safely sealed with the 2K foam seals FERMAPOR® K31. With the 2K silicone encapsulation FERMASIL®, PV junction boxes are shed in such a way that the sensitive electronics is perfectly protected against weather influences. Plastic corners, solar glass and aluminum floor plates of the solar thermal modules are permanently bonded with the 2K polyurethane adhesives FERMAGLUE®.
