1000 kW Solar Pv Monitoring System

PV-100 PV Monitoring PackageApogee Instruments' PV monitoring package is designed to work with an SMA cluster controller and includes a silicon-cell pyranometer, Class A PRT back-of-panel temperature sensor, fan-aspirated radiation shield, and Class A PRT air temperature sensor.Solar Radiation Sensor (SP-214) High accuracy, silion-cell pyranometer Measures Global Horizontal Irradiance (GHI) or Plane of Array (PoA) Irradiance 4-20 mA output signal Back-of-Panel Temperature Sensor (CS240) PT1000 Class A PRT Self-adhesive aluminum disk promotes heat transfer from panel surface Fan-Aspirated Solar Radiation Shield (TS-100) Prevents solar radiation induced errors Long life, IP55 rated fan Meets IEC 61724-1 requirements Air Temperature Sensor (ST-150) 1/8 inch diameter, Class A PRT IP67 rated Meets IEC 61724-1 requirements Silicon-cell PyranometersApogee silicon-cell pyranometers feature a monocrystalline silicon-cell detector that has the same spectral response as a PV module. The sensors quantify shortwave radiation being harnessed as electricity.Same Characteristics as a PV ModuleApogee silicon-cell pyranometers feature a monocrystalline silicon-cell detector that has the same spectral response as a PV module.Accurate and Stable MeasurementsPyranometers provide accurate readings at low-sun angles. They are cosine-corrected with directional errors less than ± 5 % at a solar zenith angle of 75°. Calibration in controlled laboratory conditions is traceable to the World Radiometric Reference in Davos, Switzerland.Rugged, Self-cleaning HeadPatented domed shaped sensor head (diffuser and body) facilitate runoff of dew and rain to keep the diffuser clean and minimize errors caused by dust blocking the radiation path. Sensors are housed in a rugged anodize aluminum body and electronics are fully potted.Output OptionsMultiple analog output options are available including: 4 to 20 mA, 0 to 2.5 V, 0 to 5.0 V, and 0 to 350 mV ranges. The silicon-cell pyranometer is also available attached to a hand-held meter with digital readout, and as a digital 'smart' sensor that uses USB communication and custom software to interface directly to a computer.
