REC Solar received certification for EPDs for silicon and multicrystalline blocks in solar cells

REC Norway AS, a subsidiary of REC Group has announced that EPD Norway has approved and published Environmental Product Declarations (EPDs) for grade silicon and for multicrystalline silicon blocks made by REC.

REC Norway produces high purity silicon for use in cells, using a unique metallurgical purification method that consumes upwards of 75% less than typically competing processes, e.g., the Siemens process as used by the majority of the industry players, mainly in .

REC Solar Norway has an annual production capacity of more than 8,000 Mt, corresponding to an annual production of about 2.5 GWp. Installed in Norway, these panels would produce around 2 TWh per year, enough to all households in Bergen. Installed in a Mediterranean country like Spain, the panels would deliver in excess of 3 TWh annually over an expected lifetime of more than 30 years.

EPD is a global, independently verified environmental declaration which summarizes the environmental impacts of all components of a finished product, production process and transport. REC’s EPDs are developed according to Product Category Rules (NPCR 029 – v1.1) managed by EPD Norway. These are internationally recognized guidelines for developing an EPD, making it possible to compare the climate impact of two products of the same category. Product Category Rules for elements of the solar cell value chain result from a project initiated by the Norwegian Solar Cluster, supported by the Norwegian Research Council.

An EPD is created based on a Life Cycle Analysis (LCA), which is in turn carried out in accordance with relevant ISO standards and guidelines. Asplan Viak, one of Norway’s largest and most recognized engineering and architecture companies within construction and infrastructure sector with an extensive experience with EPDs, has conducted the LCA for REC Solar Norway, which gave a of 11.2 kg CO2-eq per kg silicon. This is by far the lowest climate impact of any solar grade silicon product, and between 5 to 15 times less than solar grade silicon produced by the dominant production methods.

David Verdú, Managing Director of REC Solar Norway, said: “With an EPD for solar grade silicon, authorities, developers and individual customers can objectively assess their choice of solar PV product with respect to its embedded . Although do not generate emissions once installed, the production methods of a panel can differ significantly. REC Group has always been committed to a low in its solar materials and panels and is continuously striving to make manufacturing more efficient and save on resources. We are already working on the next big innovations for the industry.”

REC Solar Norway is a member of the European Council (ESMC), which advocates increased production of solar PV products in Europe, and of the Ultra Low-Carbon Solar Association, working to make it easier for customers to choose solar cell products with low carbon footprint.
