Many PV systems don’t deliver the yield they are capable of. A number of factors can lead to defects that, if not quickly detected and corrected, will impact the yield:
ENVIRONMENTAL FACTOR E.g. soiling by insects and animals, damage due to lightning, hail, storms, snow
TECHNICAL FAULTS E.g. poor cable connections, installation defects, component degradation, inverter outages
SITE CONDITIONS E.g. shade caused by tree growth, new buildings in the neighbor hood, buildup of dust and sand
THE PROBLEM: REDUCED YIELD IN YOUR PHOTOVOLTAIC SYSTEM

PVGuard® SUPERVISION PLATFORM 10 BENEFITS TO KEEP YOUR INVESTMENT INTACT
8 Vendor-independent PV Monitoring
01 | PVGuard® PROVIDES VENDOR-INDEPENDENT MONITORING› Inverters › Energy meters and environment sensors › Combiner boxes
The PVGuard® Supervision Platform supports all standard inverters, energy meters and envi-ronmental sensors. No matter whose equipment you have chosen, the acquisition and long-term storage of data from all monitored components
in your PV system is assured. Your entire plant portfolio can then be viewed through a single, uniform software platform, so increasing the efficiency of your plant supervision.
10 Management of all your power plants, worldwide, in a single platform
02 | PVGuard® MANAGES ALL YOUR POWER PLANTS, WORLDWIDE› In a single platform › With definable areas of responsibility › Using consistent, user-configurable views
The PVGuard® Supervision Platform helps you demarcate areas of responsibility when managing your power plants. You can set login and access permissions across your entire, global portfolio of plants down to a measurement channel level. Additionally, access rights can be assigned across the available views, power plants, alarms, devices and measurement channels. The integrated Fleet Manager allows you to monitor the technical details
of all PV plants, inverters and alarms across your entire fleet in a single view; this can be filtered and sorted as you wish. Whether you display it on large-screen monitors in your control room or on a tablet PC, you get an at-a-glance picture of the crucial information on your plant fleet. A large choice of supported languages facilitates location- independent plant supervision. You can change the language at any time while you work.

14 Visualization of measurement data with a resolution down to a minute
03 | PVGuard® VISUALIZES ALL ACQUIRED DATA ANDSTORES INDIVIDUAL TEMPLATES› In tables and charts according to your need › Optimized operation using color-coded heatmaps › Down to a one-minute resolution
The high resolution and accuracy of the data assists plant owners and operators during fine diagnosis. You can identify and plan any necessary maintenance in advance, thereby maximizing the availability and profitability of your solar plants. You can create your own specialized analyses at will, save them and then later recall them as a template, so that you have quick access to your most important metrics,
and can spot trends. The data from every component and plant can be brought together and evaluated according to your own wishes. Normalized and cumulative metrics are provided, derived from the raw data, and which continuously correct abnor-malities and fill in data gaps automatically. In this way, you are reliably kept aware about your PV system status at all times.

04 | PVGuard® COMPARES YOUR PV PLANT DATA› In consistent views with all relevant parameters › Regardless of location, with time zone correction › Across all components, providing a quick overview
Predefined views show the relevant components and metrics for each plant: blocks, inverters, combiner boxes, the plant control system and sensors. Data such as performance ratio, irradia- tion or the energy yield is displayed clearly and in a uniform way. This allows easy comparison, with irregularities being easy to spot. By using
consoli dated displays including derived parameters you can compare and assess plants at different locations or using different inverter concepts or module technologies. Time-zone adjusted charts assist when comparing day-by-day curves of plant data from around the world.

20 Alarm management with integrated error logging and fault analysis
05 | PVGuard® REPORTS ALARMS › Automatically from all components › With detailed fault descriptions › Clearly displaying alarm processing status
Speed up your response to outages and achieve higher plant availability through continuous monitoring as part of a systematic and efficient operations management (O&M) strategy. Specify which faults are to be monitored, their criteria and limits, taking into account the plant topology and
site-specific factors such as string layouts, shading or inverter mode. The alarm status can be called up from different plant views. Alarm management provides you with the relevant information and can record the processing of alarms.

Flexible PV systems are a prerequisite for integration into grid networks and markets. With skycontrol your PV power plants are prepared for the challenges of the future; the PVGuard® Supervision Platform lets you visualize their integration into the energy management systems. In this way you can ensure a solid connection with the network management system and obtain a visual display and documenta-tion of the curtailment.
Through its integrated control function RtSO (Real-time SCADA Operations), you can connect directly to your power plant via a customized dashboard and operate breakers. In this way, you can switch individual inverters, blocks or even the entire power station on and off. All operations are logged for later evaluation. Integrated authentication and encryption ensure a high level of security.

09 | PVGuard® PRODUCES PRODUCTION FORECASTS› For today, tomorrow or a few days ahead › At an hourly resolution for up to 7 days in advance › Updated several times a day
PVGuard® uses a self-adaptive algorithm to predict the plant output, based on high-quality, current weather data, the plant’s characteristics and its output over recent weeks. Updated several times a day, projections are available worldwide at hourly intervals and for a period of up to seven days in advance. This allows you to maximize
revenues for your photovoltaic systems in direct marketing situations or, where necessary – such as in California, Puerto Rico, South Africa and Romania – to meet the grid network requirements. The forecast data may be integrated seamlessly into your own views, analyses or reports, allowing you to visualize and evaluate it as you wish.
