What Is Temperature-Compensated Irradiance?
Role of Temperature Compensation in Accurate Solar Irradiance Measurement
Temperature-compensated irradiance plays a critical role in ensuring the accuracy of solar power plant monitoring. Even when solar irradiance remains constant, energy output from PV modules can vary depending on temperature. This is because not all incoming solar radiation is converted into electricity—some turns into heat, affecting sensor readings. Reference cell–based irradiance sensors detect these variations by simulating the photoelectric effect and adjusting measurements based on the temperature difference between the sensor and its surroundings. Accurate performance evaluations and PR (performance ratio) calculations depend on this compensation. SEVEN’s radiation sensors are calibrated to international standards (IEC-60904 and IEC-61724) and are specifically designed to deliver precise, temperature-corrected irradiance data for reliable system monitoring and performance analysis.
