The radiometric system Nesa, Belenos,is designed for monitoring campaigns of solar radiation of plants for the production of electric energy from photovoltaic source and for a simple determination of the effective yield of the plant, comparing the energy that the plant should theoretically produces with that really produced. The system is provided “ready to use”, thanks to the use of wireless technology which requires no connection.

Belenos basic version consists of:

- Robust aluminium Case containing the unit(datalogger) of data acquisition and registration on USB memory, the printer for printing the monitoring report at the end of the measurement campaign and the wireless unit for the communication with sensors.

- A couple of wirelesssensors to measure the global and diffuse solar radiation from which calculate the

incident direct radiation on photovoltaic modules.

- A couple of wirelesssensors to measure the surface temperature of photovoltaic modulesPt100 1/3 DIN.

- A wireless unit to detect the produced energy directly from the meter (option).

- Bag with pole tripod for positioning and support of radiometric sensors. System’s Operation

Belenos is configured to acquire radiometric and meteorological data according to WMO (radiation sensors on horizontal plane)and current regulations, in particular, IEC 60904.

Every system requires few specific configuration parameters for every plant as:  Plant position (Latitude and Longitude)

 Inclination angle of photovoltaic modules  Plant direction (degrees West)

 Nominal power of the plant

Every parameter is easily inserted from the operator at the beginning of every measurement campaign

in order to calibrate the monitoring on the specific plant, by keyboard setting.

Belenos, one time started, records measures, manages communications and makes the astronomical calculation of the sun position (azimut & zenit) to match exactly the measure of solar radiation acquired and that incident on photovoltaic modules. In this way it is able to accurately estimate the effective radiated energy on the analyzed plant.

Detecting at the same time also the energy really produced (KW) output from the plant directly from the meter (option), it’s able to estimate the really yield of the plant instant by instant.

All measures are continuously recorded at programmable intervals (minimum 1 time per minute) and are available both internal to datalogger and in USB removable memory. Data are easily converted in Excel format

(via web application supplied) to be then managed and processed.

Trough a simple web link, it’s also possible monitor the state of measures in real time in numeric and graphic format. At the end of the measurement campaign, pressing just a button it’s possible to obtain the print of the monitoring report in the form of a slip of paper which contains all relevant data of the plant:

Data registration is done on 2 separate memory supports:

1. Fixed support, internal to control unit, from min. 32MB of capacity.

2. Removable support (USB memory) with more capacity from 2GB to 4GB which guarantees additional safety copy of historical data. These data could be archived in encrypted form (option) to guarantee their integrity and durability up to the verification of the real plant performance. Then, data content in files are not interpretable if the user hasn’t a private key and a software provided by Nesa to remove the protection.

Belenos becomes so a real black box of the photovoltaic plant, as provides all information about the radiation received, the yield and environmental measures that have influenced the performance.

Programming

The system is totally configurable from internet browser both in local than from remote (tele programming), after authentication with user-name and password to access.

The data download happens mainly in 3 ways:

- On site: via LAN connecting a portable PC with internet browser (ex. Internet Explorer) with standard protocols TCP/IP.

- On site: taking the USB memory and linking it directly to a PC.

- From distance: via a module of data transmission GPRS (optional) linked to the serial port RS232 from the control unit, through FTP protocol (file transfer protocol) after user authentication with user-name and password.

Instant data visualization

Instant data could be displayed in real time on the display of the system, on the web page of datalogger (web server on-board) where it’s possibile obtain data in tabular and graphic format with tracking in real time of acquired measures, or connecting on FTP remote area (optional).
