    PV Plant Monitoring:-


    automation_din-rail_large.jpg

    Online monitoring is playing an increasingly important role in both residential and commercial systems. Most commercial PPA and residential leasing financing companies require revenue-grade monitoring to be coupled with online reporting tools. Many incentive programs, particularly performance-based and renewable energy credit-based ones, require accurate real-time monitoring and an automated reporting.

    Companies are also finding that online monitoring enables them to be proactive and manage their brand and often pair a monitoring system with a service agreement. A good online monitoring system can help reinforce the value of a solar PV system and follow the power yielded by the plant. In addition to the proprietary monitoring offered by most inverter manufacturers, on the market are a variety of solutions that work with most inverters to meet different application needs.

     Some of major advantages in PV Plant monitoring will help maximize your return on investment in solar energy:

     Determine actual potential energy yield,
     Optimize PV Plant to maximize efficiency,
     Monitor system performance over time,
     Future repowering and optimizations,

    Local monitoring:-

    Most simple way to perform monitoring is the local monitoring. Local monitoring is available on inverter display or on inverter control unit. Other possibilities of local monitoring includes monitoring by local PC via RS232 connection or using remote display where connection between inverter and display is usually wireless. The following parameters can usually be monitored, datalogged and stored in inverter's memory or external data logger for a particular time (up to 1 year usually).

     Common production parameters monitored and logged,

     Array voltage VDC V,
     Grid voltage VAC V,
     Array current IDC A,
     Grid current IAC A,
     Array power PDC W,
     Grid power PAC W,

     Common plant enviromental parameters monitored and logged,

     Module temperature Tmod °C,
     Ambient temperature Tamb °C,
     Global irradiance [1] G W/m2,
     Global irradiation [2] H J/m2,
     Wind speed v m/s,

    Remote monitoring:-

    Remote control and communication between inverters are based on wireless connection (Bluetooth or Wi-Fi), or via grid (power line connection). Most of the remote wireless devices cover up to 1200 m. Signal repeaters can be added to increase the range, and are GSM SMS based. Remote System can send alerts and status messages to the control center or users. The remote systems are integrated with apps for Android, iOS, and web devices. Solar monitoring mobile apps, help users to check their energy production, and the system’s performance at any time.

     

     PV Plant remote monitoring and control is being driven by:

     Reduce costs associated with remote site visits,
     Receive quick notification and act to eliminate power interruptions at a site,
     Facilitate troubleshooting,
     Program custom settings off-site,
     Update firmware remotely,
