Abstract
This project is to design and development of low-cost irradiation sensor. Calibration protocols, aligned with standards traceable to national or international benchmarks, ensure precise irradiance measurement. Laboratory experiments and field tests evaluate the efficacy of the solar cell irradiance sensor, comparing its performance against traditional pyranometer sensors across diverse environmental conditions. Traditional pyranometer sensors are expensive and prone to issues (signal degradation and calibration drift). Integration with modern digital monitoring systems is complex and requires significant investment. There is a need for a cost effective, accurate, and easy-to-integrate solar irradiance sensor for various applications, including renewable energy and environmental monitoring. By supporting sustainable development initiatives and enhancing the accuracy of solar radiation measurement, this project plays a crucial role in addressing environmental challenges and fostering informed decision making in fields such as meteorology, renewable energy, agriculture and environmental research of aging pyranometer sensors to developing a solar cell irradiance sensor using a mini solar cell. Initially, diagnostic assessments and restoration techniques, including testing, recalibration, and component replacement, were explored to combat issues like signal degradation and calibration drift in pyranometers. However, due to the unresponsiveness of the aged pyranometer sensor, the project pivoted to creating a cost-effective and accurate irradiance sensor with a solar cell. The percentage error of the solar cell irradiance sensor is lower than 10 % which makes it pretty accurate compared to the commercial irradiance meter.
