The current stage of economic development requires the use of modern service functions, which must provide the necessary technological parameters, reliability and energy efficiency of alternative sources. Operation of photovoltaic systems is subject to the peculiarities of the technological process of solar energy conversion. The purpose of this work is to analyze the capabilities of modern services based on the practical experience of the installers. The study is based on computer simulation, network technologies and features of photovoltaic power plants. The experience of operating solar stations confirms the importance of specialized resources and the feasibility of remote monitoring. This will ensure maximum installation performance. The use of modern service functions greatly simplifies the construction of a photovoltaic station and allows you to perform monitoring using network technologies. Design of a power plant with an installed capacity of 33 kW was carried out. The station operates in parallel with the network. The project was implemented using the ABB Stringsizer tool. The system generates electricity of more than 34000 kWh. This provides a profit of UAH 150000 in green tariff. Reliability indicator is a systematic control of equipment. Leading manufacturers of solar inverters have convenient services. This allows remote monitoring without visiting the facility. The Aurora Vision platform provides continuous analysis of a solar power plant. The platform uses modern means of visualizing system parameters. Aurora Vision is monitored using a wireless connection and a wired LAN connection. A secure portal Plant Management Platform has been created for data storage. To eliminate errors, you need a modern hardware-software complex. It allows you to restore the system. Aurora Manager Lite allows you to read errors and install software on any inverter in-house. Further research is recommended to investigate the features of conventional and microinverter technologies to determine the priority option for roof and ground layout.
