For reliable operation, dependable
forecasting and maximum yield
Siemens PV Monitoring Solutions
The future-proof solution for PV plants
Answers for energy.
For maximum profitability.
Siemens PV Monitoring Solutions.
Reliable operation and dependable yield forecasts are indispensable for oper­
ators of photovoltaic parks wishing to market the energy that they produce
as effectively as possible. To maximize PV plant profitability, Siemens offers
a complete solution that fulfills each of these requirements by providing full
transparency of the plant’s current performance, as well as forecasting its
future performance:
Siemens PV Monitoring Solutions.
The solution enables reliable monitoring and control of
PV plants – locally and via remote access, any time, anywhere. In the event of a malfunction, the plant operator
can immediately take appropriate action, fix any problems
quickly, and thus keep yield losses to a bare minimum.
Dependable yield forecasts are based on reliable operation, as well as integrating the latest information and
forecasts about the weather. All of which ensures that
the energy produced can be marketed as effectively as
possible.
The solution can be integrated into new and existing
plants, enabling even globally distributed PV plants to
be centrally managed.
The complete solution for your PV plant.

Your Benefits
Proven technology for reliable operation
Dependable control technology and electrical systems are essential
for reliable operation. Siemens PV Monitoring Solutions are unique
in that the underlying SPPA-T3000 control system has been successfully tried and tested in more than 1,700 power plant projects.
Appropriate remedial actions ensure that yield losses are kept to
a bare minimum. Siemens offers individual service packages that
range from remote monitoring through to maintenance and complete plant operation.
Data security that meets the strictest standards
Dependable forecasts for optimal marketing
Energy generation is forecast dependably (up to seven days in
advance). The forecast is based on precise detection and evaluation
of data, reliable operation, and the inclusion of weather information and specially-developed forecasting algorithms.
Individual service for maximum revenue
Dirt and shading on modules are identified immediately and with
precision - and reported automatically, as are technical malfunctions.
Data transfer and remote access to the control system are provided
via the Siemens common Remote Service Platform (cRSP), a gateway
that is secured and encrypted to current VBG and NERC standards.
Expandability and scalability for maximum future-proofing
Siemens PV Monitoring Solutions can be integrated into new and
existing PV parks. Equally suitable for single and multiple plants,
they even offer the option of centralized management of fleets
distributed around the globe.
For maximum yield.
Siemens PV Monitoring Solutions in detail.
Siemens PV Monitoring Solutions are based on
the world-leading SPPA-T3000 control system
and the Energy Management Suite SPPA-M3000,
which have been adapted for use in the renewable energies field, and specifically in PV parks.
Reliable data
At the third level, the Energy Management Suite SPPA-M3000 evaluates
the plant data and calculates all the economic performance indicators.
Current weather data and weather forecasts are used to generate a reliable forecast for energy production – from 15 minutes up to seven days
in advance – worldwide. This provides dispatchers with reliable data for
grid feed-in and trading. This level provides the basis for optimal marketing and generates the performance data for the plant.
Level 4: Presentatio
Level 3: Informatio
Precise detection
All field data from modules, individual strings, the weather station,
switchgear, etc. is collected from the individual containers via local
automation servers and assigned a time-stamp. This enables precise
status reporting for all components of the PV plant.
Level 2: Automatio
Level 1: Field data
Full transparency
The web-based platform “Siemens PV Portal” provides a structured overview of all data and key performance indicators for the PV plant, which
cover CO₂ savings as well as performance ratio and revenue. The Siemens
PV Portal is accessible via the internet (also using mobile devices) and
without the need to install any additional software. If several plants are
connected to the PV Portal, these can be compared directly with one
another in the Portal and use configurable reports. This level provides
a clear overview of the plant’s performance any time, anywhere, at the
press of a button.

Reliable operation
Data from the automation servers is processed in the central SPPA-T3000
application server. From here, the control system manages the inverters
and the PV park’s grid parameters, in particular active/reactive energy and
frequency. Any installed trackers are also optimally controlled from here.
Local performance indicators and technical reports, such as performance
ratio, energy production, alarm messages, etc. are calculated and made
available based on the field data. The control system allows for reliable,
automated operation of the PV plant and serves as the interface for both
operation and maintenance – both locally and via remote access.
