If you’re surveying, installing, executing maintenance or checking performance of solar panels or a photovoltaic system, the Fluke IRR1-SOL Irradiance Meter gives you the 4 critical measurements needed all in one easy-to-use tool.
• Solar Irradiation Measurements: Make instantaneous measurements to determine the watt per square meter solar irradiation, required by IEC 62446-1 standard.
• Temperature Measurement: Measure temperature by either placing the meter directly on the panel or by connecting the external probe.
• Cardinal Direction and Tilt Verification: Find cardinal direction with the compass, and verify inclination of a roof or panel with the tilt function.
• Determining the Expected Solar Production: To find the expected production at a site, determine your solar resource while taling shading into account. The solar source is measured in peak sun hours: the number of hours per day with 1,000 watts generated per square meter of solar array. Factors such as location, time of day, season, and weather conditions all influence peak sun hours.
Use the Fluke IRR1-SOL to determine the actial solar irradiance (Watts/m2) and shading at the site to develop a baseline. Once your system is installed, ensure it operates as designed by measuring its electrical charateristics and the actual power output of the array.
• Understanding Photovoltaic Array Performance: The performance of a photovoltaic array is based on its current-voltage (IV) curve. Use the IRR1-SOL to obtain the amount of solar irradiance necessary to calculate the IV curve of the power output.
• Ensuring Correct Irradiance Energy: Even when installed correctly, a photovoltaic system may not produce the expected electrical output. In order to generate the expected output, the system needs to receive the correct amount of irradiance energy to generate the DC voltage that is fed into the inverter.
