摘要
Snow and dust soiling losses require different estimating methods. PV simulation programs include placeholders for users to enter monthly soiling loss inputs, but do not provide guidance on determining their values. This paper introduces a new monthly-based dust model and a way to smoothly combine the results from it with a newly-enhanced version of Townsend's 2011 monthly snow loss model to create a year’s worth of monthly soiling inputs in a single tool. The resulting soiling profile can now be calculated using a free web‑based tool, a tool developed specifically to showcase this work. While the principal innovation introduced here is the dust model, the snow model has also now been enhanced to allow users to directly model bifacial systems. Bifacial PV is less prone to snow and dust soiling. It was not a market presence when Townsend’s snow model was introduced. Accounting for the snow‑free and dark back side of bifacial PV required amending the snow model to consider heat gain and electricity production from the back side. To join the sometimes‑overlapping periods with both dust and snow losses, a smoothing equation is presented. Lastly, the web tool is used to illustrate the monthly snow and dust losses for a modeled fixed-tilt bifacial system in Taos, NM, as well as a regional sensitivity study for fixed‑tilt monofacial systems in five other climatically diverse U.S. locations.
