Abstract:
September 1995 the monitoring of grid-connected photovoltaic (PV) powersupplies started at the test field of the Netherlands Energy Research
Foundation (ECN) in Petten, Netherlands. The results of the monitoring of the
stand-alone PV-system, composed of six AC-modules, are presented. The
capacity of the system is circa 600 Wp. The applied OK4E-100 inverters are
developed by OKE-services in Eindhoven, Netherlands, and produced by NKF
Kabel in Delft, Netherlands. Each of the inverters is mounted on the back of
a SSE RSM-95 module of Shell Solar Energy in Helmond, Netherlands. The system
is in operation since mid-October 1997. In the evaluation period of 1
November 1997 - 9 January 1998 all systems functioned properly. No failure o
occurred and the maximum power point tracking also functioned correct. Based
on measured radiation data from a monitoring campaign in Zandvoort,
Netherlands, the annual energy yield per AC-module was estimated. For an
annual radiation energy in the array area of 1087 kWh/m2 an annual yield of
circa 84 kWh was predicted for a roof-integrated system with AC-modules. The
yield factor for one year is estimated at 0.79. The realized average inverter
efficiency equals 91%. 6 refs.
