Fluke Irradiance Meters

About Fluke Irradiance Meters

Fluke Irradiance Meters, such as the IRR1-SOL and IRR2-BT models, are instruments for accurately measuring solar irradiance and the power of sunlight. These meters measure several key parameters critical to assessing and optimising solar energy systems.

Key Measurements

• Solar Irradiance: The meters measure the power per unit area of solar radiation received, expressed in watts per square meter (W/m²). This measurement is essential for determining the potential energy output of solar panels. For instance, the IRR1-SOL can measure irradiance up to 1400 W/m².
• Temperature: They assess both ambient temperature and the surface temperature of PV modules. Accurate temperature readings are vital since temperature variations can significantly impact solar panel efficiency. Users can utilise either the built-in temperature sensor or an external suction mount temperature probe for these measurements.
• Inclination and Orientation: Equipped with integrated inclination sensors and compasses, these meters measure the tilt and orientation of solar panels. Proper alignment ensures that panels receive maximum sunlight exposure, thereby optimising energy production.

Applications

• Installation and Commissioning: During the setup of solar panels, these meters help determine the optimal placement and alignment by providing real-time data on irradiance, temperature, and panel orientation. This ensures that the system is configured for maximum efficiency.
• Performance Monitoring: Regular measurements allow for the assessment of system performance. By comparing current data to expected values, technicians can identify underperforming panels or sections within an array.
• Maintenance and Troubleshooting: In cases where the system isn't performing as expected, these meters assist in diagnosing issues by providing comprehensive data on environmental conditions and system parameters. This facilitates targeted maintenance and swift resolution of problems.
