The role of outdoor testing and robotic cleaning to reduce LCoE image

In response to the global rise of utility-scale photovoltaic (PV) deployment in arid regions, QEERI at Hamad Bin Khalifa University is advancing solutions to counter environmental limitations, particularly dust accumulation, which severely hampers PV efficiency and longevity.

Why Dust Management Matters PV systems in deserts face performance issues due to dust and sand accumulation, leading to reduced light transmission and potential damage from abrasive particles. Traditional cleaning methods are labor-intensive, costly, and unsustainable. This necessitates innovative, automated solutions tailored to harsh climates.

Automated Cleaning & Predictive Maintenance Robotic cleaning systems offer a sustainable alternative, combining automation, AI, and smart sensors to clean efficiently with minimal human intervention. These systems:

  • Boost energy yield by up to 15% through better light absorption.
  • Reduce hotspots and component degradation.
  • Withstand harsh environmental conditions, ensuring system reliability.

Predictive maintenance using sensor data and AI further enhances operations by determining optimal cleaning intervals based on dust deposition, environmental monitoring, and performance metrics.

Technology-Driven Monitoring and Innovation QEERI’s integrated approach includes:

  • Sensor networks capturing real-time performance and environmental data.
  • Weather models and machine learning forecasting optimal cleaning times.
  • Satellite-based remote sensing to prioritize cleaning efforts across sites.

Future Directions in PV Plant Optimization QEERI’s R&D also explores synergies with IoT, blockchain, and edge computing to enable intelligent energy ecosystems. Innovations may include self-learning cleaning algorithms and solar-powered robotic systems for resource-efficient operation.

QEERI’s Holistic Impact Through extensive R&D, deployment of robust robotic cleaning technologies, and collaborative initiatives, QEERI supports the long-term sustainability of solar PV in desert conditions. Their work fosters capacity building, informs best practices, and strengthens resilience in the global renewable energy landscape.
