MW/day is a productivity shorthand: the amount of installed PV capacity the vendor says can be cleaned in a day. It is not a physical cleaning-rate unit unless you also know panel density, row layout, workday length and assumptions behind the claim.
One megawatt of high-efficiency modules may occupy less area than older lower-power modules. A machine can clean the same square meters per hour but appear to cover more MW/day on a denser modern array.
When comparing systems, convert claims to square meters/hour if possible and then add row-transition and setup time. For manual tools, track square meters or panels per labor hour.
For “What Does MW per Day Mean for a Solar Cleaning Robot?,” these three models give you concrete products to compare against the requirements above, instead of leaving the answer at theory.
Our strongest starting point because 5–24 ft telescopic and Universal-style extension pole make it a practical reference point for tank size, process intensity and batch workflow.
A useful second comparison because Up to 89 in. reach and 2-in-1 cleaning head make it a practical reference point for tank size, process intensity and batch workflow.
A contrasting third option because 50 in. handle and Hose attachment make it a practical reference point for tank size, process intensity and batch workflow.
