VEGETATION MANAGEMENT
Keeping PV parks efficient, safe and sustainable
Vegetation management in photovoltaic (PV) parks is a crucial aspect of operations and maintenance, because it directly affects both the performance of the solar panels and the safety of the site.
PURPOSE OF VEGETATION MANAGEMENT
Energy Efficiency: Overgrown grass, weeds, or shrubs can cast shadows on panels, reducing energy yield. Even partial shading can disproportionately lower output.
Fire Safety: Dry or unmanaged vegetation increases fire risks, especially in hot, dry climates.
Access & Maintenance: Keeping pathways and panel rows clear ensures technicians can safely inspect, repair, and clean equipment.
Biodiversity & Sustainability: Properly managed vegetation can support local ecosystems, reduce erosion, and even contribute to carbon sequestration.

OUR COMMON PRACTICES
Mechanical Control: Regular mowing, brush cutting, or string trimming to keep plants at a safe height.
Grazing: Using sheep or goats to naturally control grass and weeds. This is cost-effective and environmentally friendly, though requires careful planning to avoid damage to wiring or structures. Balancing cost with ecological benefits.
Ground Cover Planting: Establishing low-growing, slow-growing vegetation (e.g., clover, native grasses, wildflowers) to outcompete weeds and stabilize soil.
Gravel or Mulch: Sometimes used in high-risk areas (e.g., around inverters, transformers, access roads) to suppress growth.
OUR CHALLENGES
Balancing cost with ecological benefits.
Avoiding soil erosion from over-clearing.
Preventing damage to panel supports, cabling, or fencing during mowing or trimming.
Adapting strategies to local climate and soil conditions.
BEST PRACTICES & TRENDS WE OFFER TO OUR CLIENTS
Integrated Vegetation Management (IVM): Combining mechanical, biological (grazing, insects), and selective chemical methods for long-term sustainable control.
Pollinator-Friendly PV Parks: Planting wildflower meadows under and between panels to attract bees and butterflies, supporting biodiversity while keeping growth manageable.
Agrovoltaics: Dual use of PV parks for solar energy and low-impact agriculture (e.g., grazing, crops compatible with shading).
