Development of an irradiance rorecast functional tool for simulation of energy from bifacial photovoltaic panels (DiffuseBPV)

过去十年，光伏(PV)电池板的成本大幅下降，目前仅占整个系统成本的40%左右；未来光伏电池板成本的降低可能不会那么显著，对总系统成本的影响很小。然而，提高面板能量收集效率的技术引起了人们的浓厚兴趣，因为它们降低了系统所有组件的每安装瓦数成本。双面面板就提供了这种可能性--他们能够从面板的正面和背面吸收光线。量化背面获取的光在很大程度上取决于全天条件和系统部署环境：非常有限的案例研究显示了能量产量的增加，但这些研究并没有在受控条件下完成，也没有在长期部署过程中进行整合，因此只能提供定性指导。Celestica是一家顶级的太阳能制造商 面板，并希望在其产品供应中增加双面面板。渥太华大学的SUNLAB太阳能研究小组将开发一种模拟和设计工具，该工具可以在一系列客户部署条件下准确预测这项新技术对能源产量的提升，这将显著增加Celestica在全球的销售机会。

The cost of photovoltaic (PV) panels has decreased substantially over the past decade, such that they now constitute only about 40% of the entire system cost; future panel cost reductions are likely to be less significant and will only have a small effect on the total system cost. However, technologies which increase panel energy harvesting efficiency are of strong interest as they decrease the cost of all components of the system on a per installed watt basis. Bifacial panels offer just this possibility - they are able to absorb light from both the front side and back side of the panel. Quantifying the light harvested by the backside is very dependent on whole-sky conditions and the system deployment environment: a very limited number of case studies have shown the increase in energy yield, but these have not been done under controlled conditions or integrated over long term deployment, and thus offer only qualitative guidance. Celestica is a top tier manufacture of solar panels, and desires to add bifacial panels to its product offering. The University of Ottawa's SUNLAB Solar Research Group will develop a simulation and design tool which can accurately predict the energy yield enhancements with this new technology over a range of customer deployment conditions will significantly enhance Celestica worldwide sales opportunities.
