SolarVizor is a technological portal for web-monitoring of solar panels, analyzing the condition and assessing the quality of the main equipment of photovoltaic plants (PV plant) in order to maintain maximum electric power generation. In technical terms, it is the efficient operation and timely maintenance of photovoltaic plants that influence deviations from the planned and estimated investment performance of the project.
We cannot influence the weather conditions, but with the help of the SolarVizor solar plant monitoring software, it is possible to generate maximum energy under the current weather conditions.

The main tasks of SolarVizor are to monitor photovoltaic plants, identify factors that reduce the amount of electrical energy produced and provide information for their elimination.

The most common undesirable phenomena in the operation of photovoltaic plants include dusty solar panels and increased vegetation of the power plant site. Most companies have learned to successfully combat such problems by organizing the maintenance of the solar power plant on a certain schedule.

However, there are a much more significant number of problems that reduce power generation at a solar power plant, invisible to the naked human eye. These are hidden electrical problems and defects:

• increased potential on the surface of the panels;
• group and single cell short circuits;
• diode failure.

In addition, defects in the operation of electrical circuits can lead to the shutdown of entire branches of solar panels or reduce their performance. Such defects are problems in the operation of power electronics, failures in the power take-off panels (overheating, tripping of protections, breakage of lines), etc.
Detecting these problems using conventional methods requires a high degree of automation of the power plant, constant close monitoring of the operating staff and involvement of technologists performing maintenance of photovoltaic plants, search for and analysis of equipment malfunctions.
SolarVizor uses various types of mathematical analysis to detect abnormal behavior of solar panels while monitoring the power they produce. Our system uses state-of-the-art stack technology to collect and process data, transfer it to the cloud for subsequent computation and storage, and can rightfully be called a successful implementation of Industry 4.0 for solar power.
Lean facility management and timely maintenance of an industrial solar power plant can help increase the profitability of a solar power plant, and therefore the rate of return on investment. SolarVizor will help to organize all processes related to operation:

• forecasting of output based on weather conditions and the current state of the station for interaction with the system operator;
• online monitoring of the solar power plant and alerting personnel to the occurrence of undesirable phenomena;
• auditing the solar power plant and identifying defects in the solar panels at an early stage;
• notification of personnel according to configurable event scenarios;
• controlling UAVs and conducting inspection overflights;
• keeping a log of defects and planning to eliminate them;
• creation of reports on the results of the station’s work for the period.

SolarVizor is the first system that is based on the most complete digital twin of a solar plant, taking into account the characteristics of the main and auxiliary equipment, the degradation of the panels depending on the time of operation, the geolocation of each string and other elements of the plant, the weather conditions and the terrain.
With this system, it is much easier to save on the day-to-day tasks of cleaning panels and mowing grass by performing these operations where and when they are actually needed, thanks to controlling the solar plant through remote operation.
SolarVizor is an indispensable assistant in the operation of large photovoltaic plants, helping to recover investments and profits from the power plant in the shortest possible time, avoiding downtime, reduced generation and other technical risks that inevitably arise in the operation of such complex technical facilities.
