DuPont™ Tedlar® PVF film-based backsheets perform flawlessly in one of Europe’s oldest solar arrays

One of the oldest operating photovoltaic installations in Europe is located in Saint-Imier, Switzerland. Two centuries ago, the region was at the heart of the prosperous Swiss watchmaking industry. Large watchmaking factories were built and a watchmaking school was founded here. Today, energy technology and micromechanics play as large a role in the region’s economy as watchmaking did in the 19th century.

Solar panels are expected to function for 25 years or more with minimum maintenance. The specification of proven, time-tested materials—particularly the panel’s backsheet protection—are key to achieving this result.
