Solar Arrays · Rooftop & Ground-Mounted

Dirty Panels Are Stolen Revenue.

Every percent of soiling on a solar array is revenue that should be on your P&L and isn't. Most owners are losing 15–25% of annual production and writing it off as 'weather.'

What It Costs to Not Clean.

01 ──
Production losses compound
$8,000–$22,000 / MW / yr
Across a typical commercial array, annual soiling losses run into five figures per megawatt. That money walks out the meter every billing cycle.
02 ──
PPA penalties trigger
Tiered revenue clawback
Underperforming arrays under a PPA can fall below contractual generation thresholds. The cleaning bill is rounding error compared to the penalty.
03 ──
Hot spots damage cells
Cell-level permanent loss
Bird droppings and heavy soiling create localized hot spots that physically degrade cells. The damage doesn't reverse when you finally clean.
04 ──
Manual crews scratch coatings
Voided panel warranties
Pressure washers and abrasive brushes void most panel manufacturer warranties. Drone soft-wash protocols are designed to comply with them.
Why drone cleaning wins here

Built For This Property Type.

→
Production restored, fast
Most arrays see immediate 15–25% generation lift the day after cleaning. The meter tells you it worked.
→
Warranty-safe protocols
De-ionized water, controlled pressure, no abrasives. Compatible with major panel manufacturers' cleaning specifications.
→
No roof penetrations
Rooftop arrays cleaned without crews walking the membrane, dragging hoses across penetrations, or staging on roof curbs.
→
Ground-mount, no trampling
Ground-mount arrays cleaned without trucks in the field, soil compaction, or vegetation damage.
→
Quarterly programs
Dust, pollen, and biofilm cycles are predictable. Quarterly cleaning keeps production at spec without emergency calls.
→
Per-panel documentation
Drone-captured before/after imagery and per-string production data. Hand it directly to your O&M provider or PPA counterparty.
The math

The Production Math Is Brutal.

Example: 1 MW commercial rooftop array in central NC, $0.11/kWh PPA, 20% soiling loss.
Annual production at spec
~1,450 MWh
Lost generation @ 20% soiling
~290 MWh / $31,900
Annual drone cleaning program (quarterly)
$3,800 – $6,500
Net annual recovery
$25,000+
Typical ROI
400–700% in year one

Our promise

The Altitude Spotless Guarantee.

We don't ask you to take our word for it. Three promises, no fine print.
01 ──
Inspect before you pay
Before our crew leaves, we walk every cleaned elevation with you. You see the result up close and approve it — so you never pay for work you haven't inspected.
02 ──
We make it right
Notice a missed area within seven days? We re-treat it at no charge. You don't pay for an elevation until it meets your standard.
03 ──
Zero disruption, guaranteed
No scaffolding, no lift rental, no blocked entrances, no lost parking. Our work won't interrupt access to your building.
