Аннотация. Введение. Высокая эффективность фотоэлектрических панелей и стремительное снижение цен на аккумуляторы способствуют увеличению доли солнечной энергии в общем производстве электроэнергии.
Методы и материалы. Производство электроэнергии с помощью фотоэлектрических модулей и её накопление являются эффективным решением для обеспечения бесперебойного электроснабжения. Однако системы накопления требуют дополнительных затрат, что усложняет определение общих оптимальных расходов. В данной статье с помощью традиционных методов расчёта проанализированы различия в нормированной стоимости электроэнергии (LCOE), произведённой фотоэлектрическими системами с аккумуляторами и без них.
Результаты. Установлена экономическая взаимосвязь между стоимостью электроэнергии, производимой фотоэлектрическими модулями, и тарифами на передачу энергии по сетям.
Выводы. В климатических условиях Узбекистана целесообразно внедрение маломощных, локализованных солнечных электростанций, обеспечивающих надёжное энергоснабжение без потерь при передаче. Такие станции окупаются в два раза быстрее по сравнению с аккумуляторными солнечными электростанциями.
Abstract. Introduction. The high efficiency of photovoltaic panels and the rapid decrease in battery prices are contributing to the growing share of solar energy in overall electricity production.
Methods and Materials. Generating electricity using photovoltaic modules and storing it is an effective approach to ensure an uninterrupted power supply. However, storage systems require additional costs, complicating the determination of total optimal expenses. This paper analyzes the differences in the levelized cost of electricity (LCOE) generated by photovoltaic systems with and without batteries, using conventional calculation methods.
Results. An economic correlation was identified between the cost of electricity generated by photovoltaic modules and the tariffs for its transmission through power grids.
Conclusion. In Uzbekistan’s climatic conditions, it is advisable to implement small-scale, localized solar power plants that ensure reliable electricity delivery without transmission losses. These plants pay for themselves twice as fast compared to battery-based solar power systems.
