PV STATION MONITORING SYSTEM
The facilities include appropriately selected sensors for measuring parameters and data of the operation of the PV plant, i.e. solar radiation intensity sensors, outdoor temperature and operating temperature sensors of the PV generators, instantaneous power and energy meters at the output of the PV and inverter etc. The continuous recording system of the system operating parameters is compatible with the inverter technology . The monitoring system records and stores the data to allow continuous analysis of the performance of the PV park.
- Perimeter Fence Breach Detection System
- CCTV Closed Circuit Television Monitoring System
The connection of the project in question to the network was carried out with underground cables of suitable cross-section to minimize losses at the point indicated by DEDDIE.
