Рефлекторное освещение ФЭС на затененных фасадах зданий

Настоящее исследование предлагает метод использования зеркальных отражателей для компенсации потерь мощности в строительно-интегрированных фотоэлектрических системах (BIPV), вызванных затенением от соседних зданий. Экспериментальные и смоделированные данные выявили практически линейную зависимость между площадью затенения и снижением эффективности ФЭП: при затенении 25% поверхности модуля наблюдается свыше 20% потери производительности. Оптимальное соотношение площади зеркал к площади фотоэлектрических панелей (20-30%) обеспечивает увеличение суточной освещенности фасадов. Тогда как нижние этажи (1-6) подвержены значительным сезонным потерям, системы выше восьмого этажа остаются незатронутыми затенением. Результаты работы предлагают эффективную стратегию для минимизации влияния затенения BIPV в условиях высокой градостроительной плотности и высоких широт.
