Математический алгоритм реализован с помощью системы MathCad c выгрузкой и анализом данных в Microsoft Excel. Для достижения цели использовались данные о выработке электроэнергии за месяц и период эксплуатации в течение 2022–2023 гг. солнечными станциями с оптимальным неизменяющимся углом наклона солнечной панели и с системой слежения за Солнцем. Приведенный алгоритм расчета выработанной электроэнергии солнечной станцией, с учетом изменяющейся температуры окружающего воздуха, запыленности и пропускания солнечного света покрытием солнечной фотоэлектрической панели, позволил спрогнозировать выработку электроэнергии со средней абсолютной ошибкой от 0,22 до 9,8. С помощью специализированного программного обеспечения MathCad разработана математическая модель для определения солнечной инсоляции для произвольного дня и географических координат местности, на которой предполагается строительство солнечной электростанции. Приведенные экспериментальные и расчетные исследования для выбранных ясных дней, с учетом погодных условий, показали адекватность рассматриваемого метода и возможность его использования для прогнозирования выработки электроэнергии с различными углами наклона солнечной фотоэлектрической панели. В результате проведенных экспериментальных исследований установлено, что солнечная станция с системой слежения за Солнцем выработала за год на 37% больше электроэнергии, чем станция с неподвижными солнечными панелями. Метод расчета солнечной инсоляции ASHRAE (чистого неба) позволяет оценить объем выработанной электроэнергии для произвольного региона с минимальными входными данными. В дальнейшем будет проведена работа по поиску и совершенствованию методов для прогнозирования выработки электроэнергии солнечной электростанцией в пасмурные дни.</p></abstract><trans-abstract xml:lang="en"><p>The paper evaluates the generation of electrical energy by a solar power plant equipped with a solar tracking system using the ASHRAE clear-sky method for calculating solar insolation. The mathematical algorithm uses the MathCad system with data export and analysis in Microsoft Excel. Collected over a month and the operation period in 2022–2023, data on electricity generation by solar stations characterised by an optimal constant angle of inclination of the solar panel and equipped with a solar tracking system were used. By taking into account the varying ambient temperature, dust content, and solar transmission by the solar panel coating, the given algorithm allowed electricity generation by a solar panel to be forecasted with an average absolute error ranging from 0.22 to 9.8. To determine solar insolation for a specific day and the geographical coordinates of the intended construction site of a solar power plant, a mathematical model was developed using MathCad software. The experimental and computational studies carried out on selected clear days, accounting for varying weather conditions, demonstrated the adequacy of this method and its applicability for forecasting electricity generation with different inclination angles of a solar panel. It was established that a solar power plant with a solar tracking system generated 37% more electricity per year than that with fixed solar panels. The ASHRAE Clear-Sky method for calculating solar insolation allows the amount of electricity generated for a specific region to be estimated with minimal input data. Further research will focus on defining and improving methods for forecasting electricity generation by a solar power plant on overcast days.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>инсоляция</kwd><kwd>солнечная электростанция</kwd><kwd>угол наклона</kwd><kwd>фотоэлектрическая панель</kwd><kwd>система слежения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>insolation</kwd><kwd>solar power plant</kwd><kwd>tilt angle</kwd><kwd>photovoltaic panel</kwd><kwd>tracking system</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Безруких П.П.
