Meteorological data measurements An anemometer is a meteorological
instrument that provides the following meteorological measurements:

■ Ambient air temperature sensor
■ Wind speed
■ Outdoor air temperature sensor
■ Pyrometer for measuring solar insolation

Photovoltaic power output performance measurement sensors

■ AC current and voltage transducer
■ DC current and voltage transducer
■ Kilowatt-hour meter transducer
■ Optically isolated RS-422 or RS-232C modem

Sun Viewer display and Sun Server monitoring software The Sun Viewer
display and Sun Server monitoring software provide acquisition and display of real-
time data every second and display the following on a variety of display monitors:

■ DC current
■ DC voltage
