6 FAQs about [European efficiency weights for photovoltaic inverters]

How much power does a photovoltaic system produce?

"1 kWh of AC power output from a reference photovoltaic system (excluding the efficiency of the inverter) under predefined climatic and installation conditions for 1 year and assuming a service life of 10 years". Overall efficiency calculated from static MPPT and the conversion efficiency from IEC 61683 with additional measurements.

How long does a photovoltaic inverter last?

1 kWh of AC power output from a reference photovoltaic system (excluding the efficiency of the inverter) under predefined climatic and installation conditions for 1 year and assuming a service life of 10 years. a service life of 25 years.

How long does a reference photovoltaic system last?

PV Expert Meeting. Ispra, 31st October 2018 "1 kWh of AC power output from a reference photovoltaic system (excluding the efficiency of the inverter) under predefined climatic and installation conditions for 1 year and assuming a service life of 10 years".

How to define an inverter's efficiency?

There exist experimental methodologies to define the inverter's efficiency described in standards which are, however, at present under revision. Usefulness of having a single weighted average efficiency value or efficiency curves with several points. Interpolation methodology should be defined in order to apply the efficiency curves values.

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.

What is a photovoltaic system?

A photovoltaic system is an assembly of components that produce and supply electricity based on photovoltaic conversion of solar energy. It comprises the following sub-systems: module array, switches, controls, meters, power conversion equipment, PV array support structure, and electricity storage components.
