  • CENER has won two contracts. One (coordinated by CENER) on the development of standardization methods for the eco-design and energy labelling of photovoltaic products and the second project will develop a recyclability index for photovoltaic products.
  • Both contracts are funded by the Horizon Europe Programme and are being closely followed by Policy Officers from DG GROW and DG RTD of the EC.


Sarriguren (Navarre-Spain), April XX, 2024.- CENER, the National Renewable Energy Centre of Spain, participates in two projects of the European  Climate, Infrastructure and Environment Executive Agency (CINEA), in Cluster 5 “Climate, Energy and Mobility” of the Work Programme 2023-2024 of the Horizon Europe Programme. The objective of the projects is to develop methodologies to implement measures for Photovoltaic Products that are included in the Ecodesign Directive (Directive 2009 /125/EC), and the Regulation for Energy Labelling (Regulation (EU) 2017/1369).

The first project, which is called “Development of standardization methods for eco-design and energy labelling of photovoltaic products”, it lasts 36 months and it is coordinated by CENER. TÜV Rheinland Italia SRL and the German National Metrology Institute (PTB) collaborate in it. The project has two different objectives. On the one hand, it seeks to define a methodology to estimate the energy production of bifacial photovoltaic modules, and on the other hand it seeks to develop a methodology that allows determining the rate of degradation of the performance of photovoltaic modules in the long term.

Both methodologies require both simulation activities and testing and characterization of photovoltaic modules that will be developed in the partners’ facilities and laboratories. The project website is: .

The second research project, which is titled: “Development of a recyclability index for photovoltaic products”, it is planned to last 18 months and has the participation, in addition to CENER, of the University of Murcia and Viegand Maagøe, which is the coordinator of the project. The main objective is to develop a recyclability index for photovoltaic products, and more specifically for modules and inverters.

The recyclability index seeks to evaluate the capacity or ease of a certain product to be recycled, so it will not only depend on the percentage, in terms of weight, of the recyclable components, but will also take into account the presence or absence of elements and components that make recycling difficult. Furthermore, the economic and environmental value of the recovered components, among other aspects linked to the circularity of the products and components will be considered. The project website is: .

The model for estimating the photovoltaic production of bifacial modules, as well as the methodology to define the degradation rate of the performance of the modules, and the recyclability index, could be implemented within the ecodesign and energy label measures for photovoltaic products that are currently being analysed within the European Commission and whose entry into force is estimated for the end of 2024. These measures will contribute to improving the sustainability of the photovoltaic products available on the European market, providing the user with tools and information to be able to choose among the different photovoltaic products available on the European market, those that present the best performance regarding recycling, efficiency and sustainability.

Both projects require close collaboration with manufacturers and companies dedicated to the recycling of photovoltaic modules and inverters. There is the possibility of collaborating on both projects and the information is found on the web pages.
