Bird Control Australia’s Motion Activated Sprinkler keeps birds off solar panels
A proven, humane solution to prevent fouling and protect solar performance
The Challenge
Persistent gull activity was causing significant fouling on solar panels, even shortly after cleaning.
This led to reduced solar efficiency, increased maintenance, and the risk of long-term performance loss.
The Solution
A solar-powered motion-activated sprinkler was installed as a first-line deterrent. The system detects movement and emits a short burst of water, preventing birds from landing. Sensitivity was adjusted to reduce false triggers and minimise unnecessary water use.
Performance Considerations
Performance Considerations
- Bird fouling can reduce solar output by approximately 7.4%
- Dust can reduce performance by around 8–12%
- Water exposure can improve output by approximately 5–6% due to cooling effects
In this installation, water application is brief and panels are angled, allowing natural runoff. This means any temporary optical impact is minimal, while cooling and cleaning benefits remain.
Data Monitoring
Performance is being tracked using system data to compare:
- Fouled panels (pre-installation)
- Deterrent active with dirty panels
- Clean panels with ongoing protection
Early Results
Within the first 48 hours, bird activity reduced dramatically. By Day 3, there were almost no activations, indicating that birds were avoiding the area entirely rather than triggering the system repeatedly.
Outcome
The motion-activated sprinkler provides a proactive, humane, and low-maintenance solution that prevents bird fouling before it occurs—protecting solar performance and reducing cleaning requirements.
