EU RoHS directive for solar panels

What is EU RoHS?

EU RoHS refers to the EU-Directive 2002/95/EC on the Restriction of Hazardous Substances in electrical and electronic equipment which was adopted on 27 January 2003.

EU RoHS also applies to solar panels.

It restricts the use of a total of six hazardous materials in the manufacturing process of all kinds of electronics and electronic products.

The substances and their maximum limits are:

SubstanceMaximum limit (ppm)
1. Cadmium (Cd)100
2. Hexavalent chromium (Cr6+)1000
3. Lead (Pb)1000
4. Mercury (Hg)1000
5. Polybrominated biphenyls (PBB)1000
6. Polybrominated diphenyl ether (PBDE)1000

Having taken effect on 1 July 2006, the RoHS-Directive was to and has become law in the national legislations of each EU-member states. In order to ensure the legal distribution of their products within the EU, manufacturers, importers and retailers need to ensure the compliance of their products with the RoHS-requirements.

With regards to raw homogeneous materials level, the share of Cadmium must be below 0.01% while that of the substances Hexavalent chromium, Lead, Mecury, Polybrominated biphenyls and Polybrominated diphenyl ether may not exceed 0.1%. The Directive can be found here.

 

RoHS and solar PV products

The Directive exempts thin-film PV modules from the restriction on using Cadmium telluride (CdTe) in thin-film PV modules. This exemption has been further extended as by May 2011.
