Open data companion to the Solar Panel Cleaning Yield Recovery working paper and reference calculator. Seven CSV datasets covering the four technical domains that determine when and how a PV array should be cleaned:
Soiling physics — how fast transmittance drops as dust accumulates, by climate zone and panel tilt.
Water-fed pole (WFP) engineering — deionized-water resin capacity as a function of inlet TDS, and PV geometry → pole length… See the full description on the dataset page:
