Update of the Dutch PV specific yield for determination of PV contribution to renewable energy production: 25% more energy!

Abstract

Statistics Netherlands (CBS) annually publishes the contribution of renewables to the Dutch electricity supply, by following a national protocol. The amount of electricity generated by photovoltaic (PV) technology is calculated from the average installed capacity in a particular year multiplied by a specific yield value of 700 kWh per kWp installed. It was generally recognized by market stakeholders that this value was too low. Therefore a study was performed that should lead to an updated value that would be support by the market stakeholders. From several data sources PV performance data was collected, for the years 2012 and 2013, and an expert meeting was organized to come to a common advice to CBS. Consensus among the experts was reached on a specific yield of 875 kWh/kWp, to be used from 2011 onwards. This constitutes a 25% increase with respect to the old value.
