DO YOU REALLY KNOW WHAT YOUR PLANT IS DELIVERING?

4 skytron energy

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

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.

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.

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.

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.
