Modelling the Impact of Array Wiring on Electrical Output of Vertical Bifacial Agrivoltaic Installations

We present a model and study investigating the potential power output of vertical bifacial solar panels on New Jersey farms. The simulation calculates instantaneous brightness and shading based on the position of the sun and adjacent rows of panels, and uses that to calculate current and voltage values. We explore different strategies to improve the power output further. Double-high modules, which use two panels stacked together, offer significant gains per acre with only a modest increase of inter-row shading. When bypass diodes and improved inverter wiring are also used, much of the losses due to shading are avoided, and the total power output per acre is nearly doubled. In a double high configuration it is advantageous to have the top and bottom modules on separate inverter strings.

我们提出了一个模型并进行了研究，以调查新泽西农场中垂直双面太阳能电池板的潜在功率输出。该模拟根据太阳的位置以及相邻电池板排计算瞬时亮度和阴影，并利用这些来计算电流和电压值。我们探索了不同的策略以进一步提高功率输出。双高模块（将两块电池板堆叠在一起）在每英亩土地上能显著提高发电量，而行间阴影仅有适度增加。当同时使用旁路二极管和改进的逆变器布线时，大部分因阴影造成的损失得以避免，每英亩的总功率输出几乎翻倍。在双高配置中，将顶部和底部模块连接到不同的逆变器组串是有利的。
