Solar irradiance is a core environmental parameter that determines the power generation efficiency of photovoltaic modules. Accurately measuring total radiation, scattered radiation, and effective irradiance of module planes is crucial for site selection evaluation, system design, power generation prediction, efficiency analysis, and fault diagnosis of photovoltaic power plants. Traditional irradiation measurement equipment has a large volume, complex installation, and high cost, making it difficult to meet the needs of on-site mobile detection and multi-point flexible deployment. Jiangsu Jingwei Technology Co., Ltd. has launched the JW-F04 portable irradiance meter with its profound accumulation of optical sensing and precision measurement technology. With the advantages of high precision, portability, and intelligence, it provides an efficient and reliable domestic solution for photovoltaic system light energy measurement.
