This action aims at developing standardised (pre-normative) methods relevant to eco-design and energy labelling of photovoltaics. In particular, there would be two sets of methods developed:

• standardised method for the calculation and testing of the yield of bifacial photovoltaic modules; and

• standardised method for the measurement and testing of the long-term degradation of the photovoltaic modules performance (some activity started with the preparation of the IEC 63209 standard). The main aspects of interest (e.g., thermal fatigue, damp heat, etc.) should be identified.

Development of standardisation methods for eco-design and energy labelling of photovoltaic products.
