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.

This study investigates a mirror-based reflectivity approach to mitigate shadow-induced power loss in building-integrated photovoltaics (BIPV). Experimental and simulation-based analyses reveal a near-linear relationship between shading area and efficiency loss: a 25% shaded area leads to over 20% reduction in PV performance. An optimal mirror-to-PV area ratio (20-30%) enhances daily irradiance by 46,5-161.3%. While BIPV systems on lower floors (1-6) suffer significant energy losses in winter, those above the 8th floor remain unaffected by shading. The findings provide an effective shading compensation strategy for BIPV deployment in high-density, high-latitude urban environments.
