The data acquisition system consisted of a Sunny Boy 1700 inverter, Sunny SensorBox and Sunny WebBox. The Sunny SensorBox was used to measure in-plane global solar radiation on the PV modules. Additional sensors for measuring ambient temperature, wind speed and temperature at the back of the PV module were connected to the SensorBox.
A solar radiation sensor with accuracy of ±8% and resolution of 1 W/m2 installed on the PV module plane was used to measure incident solar radiation. The temperature of the PV modules was measured using a PT 100-M type sensor with accuracy of ±0.5 oC. Ambient air temperature was measured using a JUMO PT 100 U type sensor with accuracy of ±0.5 oC. A Thies small wind transmitter anemometer with accuracy of ±5% was used to measure wind speed. The SensorBox and the inverter were connected to the Sunny WebBox via a serial RS485 link and a Power Injector. Data recorded at 5-minute intervals in the WebBox was extracted via a secure digital card and read directlyinto a computer. Fig. 2 shows the Sunny WebBox, power injector and an analog electricity meter.
