Abstract
With more than 1.3 Wp of grid connected Wp per capita, the Netherlands ranks among
countries with the highest installed PV power per capita. Since the start with demonstration
systems in the early nineties, projects have increased in size and numbers. In 2002, 5 MWp of
grid connected PV-systems was installed, adding up to a total of 21.7 MWp installed gridconnected
PV capacity.
Now that the PV-market is growing and more and more consumers are coming into contact with
the technology, detailed monitoring is not necessary and not done anymore. On the other hand,
demands on quality and reliability are increasing, which makes assurance of quality all the more
important. Rumours about bad functioning PV systems spread faster than about the good
functioning ones. These rumours can affect the trust of the market in this technology.
In this report, results of the first investigation of this kind in the Netherlands are presented.
Information on quality was obtained through review of results of commissioning tests,
contacting the involved market actors, experience with operation and maintenance, through
analysis of performance data and through carrying out extra tests where needed. In this way,
information was gathered on 25% of the total installed capacity in the Netherlands.
