We study the problem of estimating the soiling ratio in photo-voltaic (PV) modules, i. e., the ratio of the real power output to the power output that would be produced if solar panels were clean.

Our third positive result is a probabilistic data structure based on locality-sensitive hashing, which achieves space in $\mathcal{O}(n\log n+nm)$ and query time in $\mathcal{O}(k\log n)$, and which answers queries with an approximation factor in $\mathcal{O}(k)$.
