Photovoltaic modules may also contain environmentally damaging materials depending on the technology deployed. However, during the production process these materials are completely bound in the cells and thus pose no risk to the environment. No case has ever been recorded of even the slightest amount of toxic material having escaped from the production cycle.

The hazardous materials contained in some modules could theoretically only be released in the case of a fire in a building. However, the concentration of such gases released in this kind of scenario would be insignificant compared with the release of other noxious emissions during the fire.

Convincing recycling concepts for the disposal of the modules already exist today. The first recycling plants for crystalline modules have already been in put into operation.

As a matter of principle, photovoltaic plants of all module types used for the generation of electricity are absolutely environmentally compatible.
