将光伏（PV）系统改装到船舶上可以帮助减少排放和运营成本。光伏系统效率中最具决定性的方面之一是面板的倾斜角和定向角的组合，因为它将影响面板接收的总太阳辐射。本研究旨在确定这些角度的月度最佳组合。分析时考虑的因素包括航行期间的船舶位置和方向、时间和当地天气状况。以日本境内的6家航运公司为例，采用人工神经网络（ANN）分析方法，根据输入因子计算了太阳能电池板接收的总辐射。通过一年的计算，比较了按最佳角度布置的面板与平面布置的面板的输出。结果表明，对于长航线船舶，较小的倾角或恒定为零的倾角是有利的，而对于短航线船舶，每月调整倾角可以获得更高的太阳能。
Retrofitting photovoltaic (PV) systems to ships can help reduce their emissions and cost of operation. One of the most determining aspects in PV systems efficiency is the combination of the inclination and orientation angles of the panels, because it will affect the global solar radiation received by the panels. This study aims to determine the monthly optimal combination of those angles. The ship location and direction during the cruise, time, and local weather conditions were the factors considered for the analysis. Six shipping lines in the territory of Japan were considered as case studies and Artificial Neural Network (ANN) analyses were employed to calculate the general solar radiation received by the panels based on the input factors. Comparisons between the outputs of the panels arranged to the optimal angles and those at flat position are presented in one-year calculation. The results show that for the long route ships, low or constantly zero inclination angles are favorable, while monthly adjusted angles can draw higher solar energy for short route ships.
