Volta Swiss, founded in 2022, is an innovative company committed to meeting the new energy requirements of our customers. We respond to today’s energy challenges by designing, supplying and installing high-performance, affordable solar systems, with a focus on energy independence.

Volta Swiss is the brainchild of Menuiserie-Charpente Rottet Sàrl, a family-run business that has been building, renovating and insulating roofs for over 50 years. In 2020, faced with growing demand for solar solutions, Rottet Charpente turned its attention to renewable energies, and Volta Swiss was born, the fruit of a collaboration between an engineer and a passionate carpenter.

In 2023, Volta Swiss becomes a pioneer in the Swiss market, representing DEYE/VTAC inverters and storage systems, offering some of the most efficient energy management solutions. At the end of the year, it broadens its horizons by entering into a strategic collaboration with GRZ Technologies, a Swiss company specializing in industrial hydrogen storage.

In 2024, it expands its offering to include HPS residential hydrogen storage solutions, as well as Swiss-style solar roof tiles, custom solar panels and customizable facade solutions.

Committed to a greener future, we offer tailor-made solutions that combine performance, accessibility and sustainability to contribute to a more energy self-sufficient world.
