Wholesale Factory 30L Cleaning Drone with Autonomous Route Planning for Large - Area Solar Panels, Roofs

We've put each unit through a pretty rigorous test cycle before it leaves—flight stability, spray presure, and autonomous route accuracy are all checked against the batch specs, and you'll get a COA with every drone that lists the actual measured values for your model.

The 30L tank variant, for instance, hits 3000psi on the hose version, but we also verify the 7.4L/min flow rate across both tank models (usually within ±3% of spec), and the 14s 28000mAh battery is load-tested to ensure it holds the 10-minute working time under full spray load.

Certifications are CE, RoHS, FCC, and ISO 9001—we've had those in place for years, so compliance isn't something you'll need to chase down. If you want an independent retest, our company can arrange that through a third-party lab (usually 2-4 weeks lead time), and we'll cover teh cost if something's off.

Most buyers go with the 30L hose model for large solar arrays because the continuous water feed saves downtime, but the 16L hose is lighter at 20kg and easier to handle on smaller roofs. One thing we don't test is performence with chemicla additives—that's on you to validate for your specific cleaning solution.

We have a 3-year warranty on the carbon fiber frame, 1 year on main parts like motors and pumps, and 3 months on wear items like nozzles and hoses—basically, the structure is built to last, but the high-wear bits need periodic replacement.
