Autonomous vegetation management for solar farms
Conventional ride-on mowers and brushcutters can't navigate solar arrays without panel-strike risk. The PANDAG G1's GPS-RTK precision, low profile and 38° slope handling make it the right tool for solar farm vegetation control — daily, autonomous, and at scale.
By the numbers
Why this matters for the sector
Panel-strike risk eliminated
The PANDAG G1's low profile and GPS-RTK navigation keep it precisely within mapped row corridors. Unlike ride-on mowers — where a misjudged turn can clip a panel — the autonomous unit physically cannot deviate from its mapped path. The single biggest operational risk in conventional solar farm mowing simply doesn't apply.
Continuous operation, fleet-scalable
Solar farms are large enough that vegetation regrowth becomes a treadmill problem on a fortnightly contractor cycle. Autonomous operation runs continuously — daily, every day of the year — and scales by deploying multiple units across the site. No driver scheduling, no weather-related delays, no contract gaps.
Vegetation height standards stay consistent
Most solar PPAs and O&M contracts specify maximum allowable vegetation height under and between panels. Daily autonomous mowing keeps height at a constant level, eliminating the saw-tooth pattern of contractor-cycle mowing that periodically violates the standard mid-cycle.
Fire risk mitigation through consistent height control
Tall, dry vegetation under panels is a known fire-load risk for Australian solar farms, particularly in summer. Continuous height control via daily autonomous mowing maintains a low, consistent fuel-load profile rather than the saw-tooth profile of contractor mowing.
Slope handling for site terrain
Many Australian solar farms are sited on rolling rural land that exceeds ride-on safe operating slopes. The PANDAG G1's 38° rating covers slopes that would be unsafe to mow with conventional equipment, eliminating the brushcutter-by-hand work that conventional contractors typically charge a premium for.
Operator-free under panels
Removing the operator removes the lone-worker risk, the heat-stress risk in summer, the electrical proximity risk, and the workplace-injury liability associated with conventional under-panel mowing. The unit operates without anyone needing to be in physical proximity to live arrays.
Common questions
Can autonomous mowers actually navigate solar farm rows safely?
Yes — the PANDAG G1 used by AutoAcre uses GPS-RTK navigation accurate to centimetre level, with mapped row corridors that the unit physically cannot deviate from. Panel-strike risk is effectively zero compared to operator-driven ride-on mowing, where the leading cause of damage is misjudged turns near panel edges.
How does autonomous mowing handle solar farm slopes?
The PANDAG G1 is rated to 38 degrees, well above the typical ride-on safe operating limit of 15-20 degrees. Many Australian solar farms are sited on rolling rural land where conventional ride-on mowing requires brushcutter follow-up; the autonomous mower covers those sections directly.
What about fire risk under solar panels?
Tall dry vegetation under arrays is a known Australian solar fire-load risk. Daily autonomous mowing maintains a continuous low height profile rather than the saw-tooth pattern of contractor cycles — keeping fuel load consistently low rather than periodically violating it. AutoAcre's deployment can be configured to enforce a specific maximum height standard.
Can the autonomous mower meet our PPA / O&M vegetation height requirements?
Yes. Most solar PPAs specify a maximum allowable vegetation height (commonly 150-300mm). The PANDAG G1's daily operation cycle keeps height at a constant set-point rather than allowing it to grow up to a fortnightly cut-down. AutoAcre configures the height target during deployment.
How does this compare to fortnightly contractor mowing?
Cost-equivalent or lower over a 12-month period for sites above ~100 acres, given the elimination of operator scheduling, weather delays, panel-strike insurance, and brushcutter follow-up on slopes. The bigger gain is reliability — autonomous operation doesn't have weather windows, sick days, or rebooking gaps.
Does AutoAcre service solar farms outside the Northern Rivers?
AutoAcre's primary service area is Byron Shire and Ballina Shire, but AutoAcre's commercial operations extend to wider Northern NSW for commercial deployments. Solar farm projects are scoped on a per-site basis — contact AutoAcre to discuss your site location and scale.
What about sheep grazing as an alternative — why mowing?
Sheep grazing is a viable solar vegetation strategy at some sites but introduces livestock management overhead, infrastructure (water, fencing, shade), and seasonal performance variability. Autonomous mowing is a simpler operational model with no livestock dependencies and predictable per-hectare cost.
How are autonomous units secured on remote solar sites?
GPS geofencing, PIN-locked operating systems, and remote disable. If a unit is moved off the mapped site without authorisation, it locks itself and AutoAcre is notified. Theft of working autonomous mowers is rare because they are useless without their dock and operating account.
