About Megger Irradiance Meters
Megger Irradiance Metres, particularly the PVM210, model, are compact, handheld instruments for measuring solar irradiance (solar power density). These accurate and reliable metres are used throughout the lifecycle of PV systems, from initial site surveys to ongoing maintenance. They provide essential data to optimise energy capture and ensure the efficient performance of solar installations.
What Do They Measure?
Megger Irradiance Metres primarily measure solar irradiance (Watts per square metre - W/m2), which is crucial for assessing the performance and efficiency of solar panels. They may also measure:
- Temperature (°C or °F): Ambient and PV module surface temperature, is crucial for understanding PV performance, which is affected by heat.
- Orientation & Tilt Angle: To help optimise panel positioning for maximum sunlight capture.
Applications
Megger Irradiance Metres are essential for:
- Solar Site Assessment: Evaluating solar resource potential at proposed installation sites and conducting shading analyses to optimise system design.
- PV System Installation & Commissioning: Fine-tuning panel orientation and tilt during installation and verifying system performance during commissioning.
- Performance Monitoring & Maintenance: Regularly checking system performance, troubleshooting underperformance, assessing soiling losses, and calculating performance ratios to ensure long-term efficiency.
