2. MBSoiling Station
MBSoiling Station series-700is advanced range of soiling station. The soiling station
provides following advanced functions:
3. Uses latest ARM 32 bits processor.
4. Real time monitoring of clean and soiled PV panels.
5. Regular monitoring and filtering of soiling parameters.
6. All measurements are available via serial RS485 (MODBUS RTU) and ETH
(MODBUS TCP) ports.
7. Modem 4G (optional) for communication of logged files to remote servers.
8. MODBUS TCP (master and slave), SNTP, FTP and DNS.
9. All parameters are available as MODBUS (RTU or TCP) slave parameters.
10. External SD memory card (16GB) for data logging.
11. Programmable data logging interval.
12. Embedded webserver for configuration of soling functions and diagnostics (real time
view of measured parameters). No programming is required.
13. MyPage – to display user selected parameters in one webserver page.
14. Internal battery backed up real time clock (RTC).
15. Data file transfer to two file servers.
16. Internal memory of 32MB and expandable SD card memory up-to 16GB.
17. Log for user activity and device messages/ faults.
18. Calibrate soiled panel with respect to clean panel.
19. Powered via solar charge PV panel or AC power supply.
20. Optional – automatic cleaning of soiled and clean panels. With monitoring of cleaning
liquid level in the tank.
21. Excellent on-site diagnostic support with soiling station status and value reports.
2.1 MBSoiling Station Applications
The soling station is used to measure power generation losses due to soiling of panels
in of photovoltaic plant. Number of soiling stations to be installed in a plant will
depend on its topology and size. Guidelines provided in IEC-61724-1 should be
followed.
Soiling station can be used in various applications:
•
Site resource and generation capacity assessment.
•
Scheduling of PV panel cleaning.
•
Plant performance evaluation.
2.2 Soiling Parameters
Following soiling parameters are measured and calculated:
Sl.
No.
