Answers before you shortlist a system
Have a question specific to your array? Send the layout and operating conditions to our technical team
Which cleaning machine is suitable for my project?
The correct model depends on plant size, array layout, panel tilt, module gaps, soiling type, water availability and the daily cleaning target. Share those parameters for a project-specific recommendation.
Can your equipment clean PV modules without water?
Yes. R1, R2 and G4 support dry-cleaning configurations. Suitability depends on dust characteristics and module condition.
What tilt and module gaps can the robots handle?
R1 and R2 are specified for working angles up to 20°. Maximum-span guidance is 20 cm for R1 and 25 cm for R2. Final compatibility requires layout confirmation.
Will the brushes scratch solar module glass?
PV-specific PBT and nylon brush options are available. Brush selection, cleanliness, operating pressure and the presence of abrasive particles all matter, so the operating procedure must match site conditions.
Do you support distributor and OEM cooperation?
Yes. WaterSprayElephant works with regional partners on product configuration, voltage and plug options, sales materials, technical training and spare-parts planning.
What information is needed for a quotation?
Please provide project country, plant capacity or area, module layout, tilt, row dimensions, horizontal and vertical gaps, soiling conditions, water and power availability, plus the desired cleaning frequency.
