Clear panels and clean ground. From the air.
Utility & Commercial Solar

Clear panels and clean ground. From the air.

Weeds under the arrays and dust on the panels both cost you generation. We handle both from the air, without crews walking row after row in 110 degrees.

The Problem

Ground crews can't keep up with the desert.

Utility-scale sites in Arizona fight two battles at once. Vegetation creeps up under and around the racks, shading modules and raising fire and compliance risk. Desert dust films the panels and quietly drops your output between rains. The legacy answer is crews on foot in 110 degree heat, water trucks, and slow passes that never quite catch up.

Our Process · 3 Steps

A clear path to a treated site.

  1. 01

    Site Assessment

    We fly the site to map vegetation pressure and panel soiling, then prioritize the areas worth treating first.

  2. 02

    Aerial Application

    The DJI Agras T100 spot-sprays herbicide under and around the arrays and applies a low-pressure rinse to soiled panels. No crews on the array, no trucks down every row, and the same flight plan every pass.

  3. 03

    Verification & Reporting

    You get coverage maps and before/after imagery your O&M team and asset manager can file.

What You Get

Less risk. Better coverage. Real ROI.

Every job ends with documentation you can hand straight to your auditor or asset manager.

  • Knock down weeds and brush under and around utility-scale arrays
  • Clear dust from panels with a low-pressure rinse and no foot traffic on modules
  • Keep crews out of the heat and out from under live racks
  • Use less water than truck-and-hose crews
  • Documented coverage maps and before/after imagery for your asset manager
Why Fieldmark

Built for owners and operators.

Built for AZ Desert Sites

We know monsoon dust, alkali soils, and the vegetation pressure of Maricopa, Yuma, and the I-10 corridor.

No Foot Traffic on Modules

Aerial application means no walking on panels and no scaffolding between rows.

Warranty-Aware Methods

We use low-pressure rinses and approved products, and we'll provide method statements your warranty team can review.

Part 107 + Insured

Our pilots hold their FAA Part 107 and we carry $1M aviation liability. Part 137 and our AZ Dept. of Agriculture license are in progress.

FAQ

Common questions.

Do you spray weeds or wash panels?+

Both. Most sites need vegetation control under the racks and periodic dust removal on the modules. We can do them on the same mobilization.

Will washing void my module warranty?+

We use low-pressure rinses and products compatible with major OEM warranty terms, and we provide method statements your warranty team can review before we fly.

Can you work over energized arrays?+

Yes. Our pilots are trained for energized-site protocols and we coordinate with your O&M for any required hold points.
