6 FAQs about [European Specifications for Photovoltaic Inverters]

What is the consolidated version of the photovoltaic inverter standard?

The object of this standard is to provide minimum information required to configure a safe and optimal system with photovoltaic inverters. This consolidated version consists of the first edition (2014) and its amendment 1 (2016). Therefore, no need to order amendment in addition to this publication.

What is the 'Euro efficiency' of a solar inverter?

The proposed requirement is based on the EN 50350 method for calculating the ‘Euro Efficiency’ of an inverter. This is an important derating factor for the performance of a solar PV system, so the removal of the worst performing, sub 94% efficient inverters would contribute as a minimum requirement for the inverter derating factor.

What are ecodesign requirements for the durability of PV inverters?

The formulation of Ecodesign requirements for the durability of PV inverters could follow an approach conceptually similar to the one used for PV modules. The design qualification of inverters according to test sequence set out in IEC 62093 is proposed as a minimum requirement.

What is solar photovoltaic (PV)?

This campaign was planned to start in January 2019. Solar photovoltaic (PV) modules generate electricity from sunlight. Using an inverter, this electricity can be fed into the mains electrical supply of a building, or directly into the public electricity grid.

What is the average irradiation yield of photovoltaic modules in Europe?

This is the annual average yield of optimally oriented modules in Europe, weighted according to the cumulative installed photovoltaic power when excluding degradation effects (Wyss et al., 2015). Frischknecht et al. (2015) use an irradiation of 1700 kWh/m2/yr, representative for Southern European (Mediterranean) conditions.

What standards are available for the energy rating of PV modules?

Standards available for the energy rating of PV modules in different climatic conditions, but degradation rate and operational lifetime need additional scientific and standardisation work (no specific standard at present). Standard available to define an overall efficiency according to a weighted combination of efficiencies.
