LCA of Voltec Solar photovoltaic modules

Voltec Solar
Voltec Solar, a French manufacturer of photovoltaic modules based in Dinsheim-sur-Bruche (Alsace), is committed to eco-design and transparency. In this context, the company has decided to rigorously assess the environmental impact of its products in order to publish a Product Environmental Profile (PEP) in compliance with European standards (ISO 14044, EN 15804+A2, etc.).

Our mission

Kapstan helped Voltec carry out a complete LCA of its photovoltaic modules (TOPCon technology), using a “cradle to grave” approach. The study covers the entire product life cycle:

  • extraction of raw materials,
  • cell manufacturing in China,
  • module assembly in France,
  • transport, use and end-of-life.

Plant-specific data from Voltec was collected over a 12-month period and cross-referenced with international reference databases (Ecoinvent, IEA) to accurately model the environmental impacts at each stage of the life cycle.

This analysis highlights the benefits of more responsible, local production — notably due to the use of low-carbon electricity during the final manufacturing stages in France. The published Product Environmental Profile (PEP) enables Voltec to provide its customers with clear, standardized, and verifiable information on the environmental footprint of its modules — a true competitive advantage in the European market.

~70 %
of GHG emissions come from the manufacture of photovoltaic cells in China
2,4%
of the total weight of the module and packaging corresponds to silicon, the main component of photovoltaic cells
30 years
modelled lifetime, with a performance degradation of 0.4% per year.
The team was responsive, flexible and attentive to our specific needs. We would like to pay special tribute to Juliette Leroy, for her commitment, pedagogy and thoroughness throughout the assignment.

In a constantly evolving sector, it's a real asset to be able to rely on a firm capable of taking a step back, adapting its methods and supporting us with rigor and kindness.
