Description

MAIN FEATURES 

The MicroSOLAR meteorological stations have been designed and constructed to measure the solar radiation and the other climatic conditions which can affect the performance of photovoltaic plants. The monitoring is carried out in compliance with IEC 61724, CEI 82-25 and IEC 60904 standards, using Geoves professional instruments and  other main manufacturer sensors in the field of radiometry.

MicroSOLAR stations are extremely versatile and, in the basic version, measure the solar radiation, the air and the panel temperatures and the wind speed. In the models more complex MicroSOLAR can interface the following signals:

• 4-20mA signals from inverters or other external devices
• Automatic sun trackers 
• Silicon cell or thermopile pyranometers (ISO9060 Secondary Standard, First or Second Class of accuracy)
• Other meteorological sensors to measure environmental parameters in compliance with WMO (World Meteorological Organization) that can affect the performance of photovoltaic plant (eg. rel. humidity, rain, etc…)

The data transmission is performed in two ways: 1) Via LAN/ethernet cable, 2) wireless GPRS with data sending on a FTP area,  3) manually downloading the data from the SD Card. Furthermore the istantaneous data of each meteological measure can be available on a RS485 ModBus output to connect the datalogger to external SCADA.

ADVANTAGES

Conformity

• Dataloggers and measurement stations: IEC 61724, CEI 82-25 e IEC 60904 
• Pyranometers and radiometers: ISO9060, ISO 17025 e WMO 
• Meteorological sensors: WMO Annex 8

Accuracy, reliability and robustness 

• Measurement sampling time 1 second with data storage every 5 (default), 10-15-30 or 60’
• Certifiability of all meteorological sensors by accredited laboratories (Accredia, WMO, Measnet, etc…)
• Instruments, cables, brackets and datalogger enclosures made in stainless materials able to resist in any working conditions (direct irradiation, thermal excursions, salinity, sand, wind gusts, hail, etc…)
• Data protection system against manipulation

Versatility, compatibility and easiness of using

• Each station can be fix with several kind of poles and brackets, or portatile with carrying case for instruments and foldable tripod for the on-site installation.
• Data storage in TXT standard format with values separated by commas (CSV format)
• Automatic procedure of GPRS aerial aiming by datalogger with on-site control of reception GPRS signal
• On-board display for measurement reading
