The relevance of the presented development is due to the need to create a device to read and process information from an experimental array of solar panels. The purpose of the array is to obtain reliable data for the verification of models for estimating photovoltaic power potential indicators used in justifying the feasibility of the adoption of solar power plants in the eastern regions of Russia. We present a description of the main and auxiliary equipment of the experimental array. The array’s solar panels are arranged in different ways so as to determine the most efficient tilt angle and justify the need for building a sun-tracking system. The proprietary device based on the Arduino microcontroller was designed to read and write the value of instantaneous power of solar panels. The sensor that will monitor the amperage is ACS712, which is connected to the gap of the power circuit. The study provides a diagram of the current meter and describe its operation. We outline the main stages of subsequent data processing.

Substantiation and verification of the energy and economic calculations for solar power plants require initial data and experimental results. The paper proposes a device developed for monitoring and processing information from the experimental solar panel facility. The facility aims to obtain reliable data for the verification of models designed to assess solar resource indices used to justify the performance of solar power plants in the eastern regions of Russia. The device developed for monitoring the energy characteristics of solar panels has additional capabilities to transmit data to the server. A method proposed to transfer data to a server employs a Bluetooth module and a singleboard computer Raspberry Pi as an intermediate communication center. The results of the preparatory work for monitoring weather conditions and the Peleng SF-06 pyranometer readings, which employs the developed logger and relies on the proposed method of data transfer to the server are described.

Актуальность разработки обусловлена необходимостью создания устройства для сбора и обработки информации с экспериментального стенда солнечных панелей. Назначением стенда является получение достоверных данных для верификации моделей оценки показателей гелиопотенциала, использующихся при обосновании эффективности применения солнечных электростанций на территории восточных регионов России. Дано описание основного и вспомогательного оборудования экспериментального стенда. Солнечные панели стенда разноориентированы для определения наиболее эффективного угля наклона и обоснования необходимости применения следящей за солнцем системы. Для снятия и записи мгновенной мощности солнечных панелей разработано устройство на основе микроконтроллера Arduino. Для мониторинга показаний силы тока используется шунтовый амперметр, подключаемый в разрыв цепи питания. Приведена схема счётчика тока и описана его работа. Приведены первичные результаты собранных данных. Намечены основные этапы дальнейшей обработки данных.
