NOTE:
Both panels will generally soil at the same rate. The soiling ratio is most important the day
after the reference panel is cleaned.
If zero stable data points are recorded during the previous day, the SLI will show NAN. If the
minimum number of stable data are recorded, the soiling loss indexes will update at midnight.
