Soiled panels are silent revenue leaks.
Arizona dust steals 5–25% of your generation between rains. We restore it from the air, without crews on the array and without trucking in water.
The Problem
Manual washing is slow, water-heavy, and risky on hot panels.
Ground crews need water trucks, scaffolding, and shutdown coordination. They walk between rows in 110° heat, scratch coatings, void warranties on tracker hardware, and work too slowly to keep pace with monsoon dust. Meanwhile your O&M team is watching production curves drift down and the asset manager is asking why.
Our Process
A clear path to a treated site
Soiling Assessment
We fly a thermal and visual scan to quantify soiling loss and prioritize the strings worth cleaning first.
Targeted Aerial Wash
DJI Agras T100 with low-pressure nozzles applies a deionized rinse — no abrasion, no walking on panels, no shutdowns required for most arrays.
Production Verification
Post-clean thermal pass and 7-day production delta so you can prove ROI to ownership.
What You Get
Less risk. Better coverage. Real ROI.
Every job ends with documentation you can hand straight to your auditor or asset manager.
- Recover 5–25% of lost generation within days of cleaning
- Use up to 80% less water than truck-and-hose crews
- Zero foot traffic on modules — protects coatings and warranties
- Clean 5–10 MW per day per drone, scalable with crews
- Documented thermal + production data for your asset manager
Why Precision Spray Co
Built for owners and operators
Built for AZ Desert Sites
We know monsoon dust, alkali soils, and the specific soiling profiles of Maricopa, Yuma, and the I-10 corridor.
No Shutdown Required
For most fixed-tilt and tracker arrays, we clean live — no lost generation during the wash.
Compatible With Tier-1 OEMs
Our methods preserve module warranties from the major Tier-1 manufacturers.
Insured for Utility Sites
$2M aviation liability and we carry the certs your safety team will ask for.
FAQ
Common questions
Will drone washing void my module warranty?+
Our process uses low-pressure deionized water and approved surfactants compatible with major Tier-1 OEM warranty terms. We provide method statements your warranty team can review.
How much water do you bring per MW?+
Roughly 1/5 the volume of truck-and-hose crews. We can stage from a single bulk tank for entire site campaigns.
Can you fly over energized arrays?+
Yes. Our pilots are trained for energized site protocols and we coordinate with your O&M for any required hold-points.
