FAQ

The energy performance certificate (EPC) or energy passport is the quality label that defines the energy performance of a residential building. The certificate provides information on the energy efficiency of residential buildings and thus allows comparisons to be made with other residential buildings. Thus, even without technical knowledge, the consumer can assess the energy quality of a residential building.

No. The relationship with the supplier does not change following the installation of the new electricity and/or gas meter. Each customer's supplier will be notified of the meter change automatically by the network operator.

Following a European directive enacted by Luxembourg into national law, all electricity and natural gas meters on national territory must be changed, regardless of the network operator. This means more than 300,000 electricity meters and more than 80,000 gas meters.

According to the law of 9 June 2022 on waste electrical and electronic equipment, the producer is responsible for the collection and processing of photovoltaic panels.

Producer means any natural person or legal entity who manufactures photovoltaic panels in Luxembourg or initially imports them onto the Luxembourg market. Any person established in another Member State or in a third country who, on a professional basis, supplies photovoltaic panels directly to a user in Luxembourg is considered a producer. In practice, in the majority of cases, this is the installer of the photovoltaic plant in Luxembourg.

Possibilities for owners to dispose of their old photovoltaic panels 

For photovoltaic panels put on the market before 13/08/2005 :

• in case of replacement of the photovoltaic panels, the take back of the old panel is free of charge and must be ensured by the company supplying the new equipment
• in case of dismantling of the photovoltaic panel (non-replacement of the panel), the removal by a professional collector is done against payment by the user

For photovoltaic panels placed on the market after 13/08/2005 :

• free take-back by the producer who bears the costs of collection and recovery of the photovoltaic panels. 

In general, all photovoltaic panels are recyclable.

Indeed, there are risk-free procedures for silicon-based panels as well as for thin-film panels containing cadmium. Moreover, recycling is regulated by the European Directive 2012/19/EU on waste electrical and electronic equipment, which is transposed into national law by the law of 9 June 2022 on waste electrical and electronic equipment: this framework currently requires at least 80% of the mass of a photovoltaic panel to be prepared for reuse or recycled, and 85% of the mass to be recovered.

The recycling rate of photovoltaic modules is nevertheless close to 100%, considering that the modules are generally composed mainly of glass, aluminium and other metals. Net modules usually contain very limited amounts of synthetic materials, such as silicon or other minerals. However, it is technically possible to recycle these elements, even if the processes for extracting them are not yet cost-effective. Thus, these materials are currently mainly used for thermal recovery.
