Applications of the IRR1-SOL
Photovoltaic System Design & Site Surveying
Evaluate solar resources at a site by measuring sun irradiance (W/m²) and identifying shaded areas. This helps calculate expected energy output in terms of peak sun hours—the number of hours per day when solar irradiance averages 1000 W/m². These readings are influenced by geographic location, time of year, weather conditions, and site layout.
System Commissioning & Power Output Validation
Once the PV system is installed, confirm it’s functioning properly by assessing its electrical characteristics and actual power output. Use the IRR1-SOL to measure solar irradiance—an essential input for evaluating the system’s current-voltage (IV) curve and verifying performance against design expectations.
Performance Comparison & Diagnostics
Even well-designed systems can underperform. If a system isn’t producing the expected electricity, the cause may be insufficient irradiance. The IRR1-SOL helps diagnose underperformance by confirming the available irradiance, ensuring that the PV array is receiving adequate energy to generate the required DC voltage for the inverter.
