论文摘要
西方垂直和朝南的最佳倾斜双面农场的双面增益已经良好。一个人想知道，通过跟踪太阳是否可以进一步改善双面增益（和相关的LCOE）。跟踪双面PV具有提高温度灵敏度，增强的弥漫性和反照率光收集，扁平能量输出，减少污垢等的优势。单种族跟踪已经提供了许多这些优势，因此双面跟踪的相对优点并不明显。在本文中，我们使用详细的照明和依赖温度的双面太阳能农场模型来表明，与赤道附近的固定倾斜双歧杆菌PV相比，双面跟踪PV可提供高达45％的能量增益，而在追踪单元农场的固定倾斜性双面PV和约10％的双面能量增益（约10％）的能量增益。最佳音高进一步改善了跟踪双面种族农场的增益。我们的结果将通过展示全球部署能源收益的全球趋势来扩大对双面技术的范围和理解。
The bifacial gain of East-West vertical and South-facing optimally-tilted bifacial farms are well established. One wonders if bifacial gain (and the associated LCOE) may be further improved by tracking the sun. Tracking bifacial PV has advantages of improved temperature sensitivity, enhanced diffuse and albedo light collection, flattened energy-output, reduced soiling, etc. Monofacial tracking already provides many of these advantages, therefore the relative merits of bifacial tracking are not obvious. In this paper, we use a detailed illumination and temperature-dependent bifacial solar farm model to show that bifacial tracking PV delivers up to 45% energy gain when compared to fixed-tilt bifacial PV near the equator, and ~10% bifacial energy gain over tracking monofacial farm with an albedo of 0.5. An optimum pitch further improves the gain of a tracking bifacial farm. Our results will broaden the scope and understanding of bifacial technology by demonstrating global trends in energy gain for worldwide deployment.
