Bottom-row string shading
Grass growing beneath tables shades lower solar cells, subtracting valuable generation every afternoon throughout the summer.
Specialist Service · Min 1,000 m² · From €1,500
Solar farm vegetation control with a low-profile robot that navigates under tables
Tall vegetation beneath module racks causes bottom-cell shading, reduces summer generation yield, and poses a major fire risk when dry. We clear it with a 51 cm radio-controlled machine that works beneath structures without manual crews or chemical herbicides.

Solar Farm Vegetation Management
The impact of uncontrolled vegetation on a solar farm
Heightened wildfire hazard
Dried summer grass lies directly adjacent to string cabling, combiner boxes, and trackers. A localized hotspot or electrical fault can ignite it in seconds.
Hazardous manual crews
Backpack brushcutters propel high-velocity gravel against module backsheets and glass, while workers strain in hazardous ergonomic conditions under racks.
The core challenge isn't simply cutting grass. It's clearing under solar tables without placing human crews in danger.

Technical & Regulatory Compliance
51 cm table clearance, summer fire prevention, and zero herbicides
Solar vegetation management is an essential asset protection, risk management, and environmental compliance operation.
Table clearance: why 51 cm is the industry standard
On single-axis trackers and fixed racks, lower table edge height changes constantly with tracking angles and topography. With an ultra-low 51 cm profile, our machine glides safely beneath modules with zero risk of collision with modules, cable trays, or grounding clamps.
- Unobstructed clearance under 100% of standard solar tables
- Total protection for string cabling and lower junction hardware
- Operator controls the unit safely from the perimeter aisle
Summer wildfire prevention: zero fuel load
During hot dry summer months, wild brush turns into high-speed tinder. Bordering combiner boxes, trackers, and inverters, any thermal anomaly or electric arc can spark a catastrophic fire.
- Full compliance with Wildfire Self-Protection Regulations
- Essential prerequisite for valid plant insurance coverage
- Perimeter firebreak swaths along security fencing
100% mechanical & ecological: zero herbicides
Chemical herbicides such as glyphosate are strictly banned or heavily penalized by Environmental Impact Statements (EIS) and watershed authorities. Our mulching cut is 100% mechanical with zero chemical runoff.
- ISO 14001 Environmental Certification audited by OCA Global
- Zero groundwater contamination or plastic conduit degradation
- Fine organic mulch blanket prevents soil erosion

Method Comparison
Robot, manual crew, herbicide, or grazing: how each impacts your plant
| Criteria | Remote-Controlled Robot | Manual Crew | Chemical Herbicide | Sheep Grazing |
|---|---|---|---|---|
| Clears under tables | Yes: 51 cm profile | Worker crawling under structure | Sprayed under tables | Only if clearance permits |
| Module damage risk | Zero: crew and cutting heads outside rows | High: flying stones hit glass & backsheet | Zero mechanical impact | Scratches on cabling & frames |
| Personnel safety risk | Operator stationed in wide aisle | Crews crouching with blades under steel | Chemical handling risk | Low |
| Chemical runoff | None | None | Yes (groundwater penalty) | None |
| Operational logs | GPS zone and hour log | Handwritten sheet | Application log | None |
| Seasonal availability | Guaranteed scheduled dates | Subject to seasonal labor shortage | Restricted by weather & laws | Subject to livestock availability |
While grazing and herbicides exist in some regions, Clean Sunny strictly utilizes mechanical robotic clearing.

Frequently Asked Questions
Questions regarding solar farm vegetation control
What is the minimum plant size for vegetation clearing?
We work on commercial and utility-scale installations starting from 1,000 m², with a minimum mobilization service fee of €1,500. We do not service residential gardens.
Can the machine damage string cabling under tables?
No. The machine has an ultra-low 51 cm profile and the cutting deck is fully enclosed. The operator maintains line-of-sight from the perimeter aisle, preventing contact with hanging cables or combiner boxes.
Does robotic clearing throw stones against solar panels?
No. Unlike manual nylon brushcutters that spin at high RPM and launch loose stones at solar glass, our mulching blades chop downward into the turf, safely pulverizing vegetation into a fine mulch without stone projection.
Do you use chemical herbicides?
Never. Clean Sunny is certified under ISO 14001. We exclusively utilize 100% mechanical clearing to protect soils, comply with Environmental Impact Statements, and preserve plant warranties.
How many times per year should a solar farm be mowed?
We recommend two annual interventions: once in spring right before grasses reach module heights, and once in early summer to eliminate the wildfire fuel load before dry weather peaks.
