Application of plane mirror reflection in photovoltaic systems
https://doi.org/10.15518/isjaee.2025.02.027-037
Abstract
This study proposes a planar mirror-based method to enhance irradiance on photovoltaic (PV) modules, aiming to improve energy output efficiency through geometric-optical optimization. The dynamic effects of critical parameters – including mirror rotation angle (θ = 15°-85°), mirror-to-PV distance (r = 1-10 m), and reflective area (A = 1-5 m²) – on the spatial distribution of effective irradiance were systematically investigated. Experimental results demonstrate that under optimal configurations (θ = 75° ± 5°, r =3,2-4,1 m), an irradiance gain of approximately 12,7% is achievable. This work provides a reference framework for designing low-complexity reflective enhancement systems tailored to PV applications.
