In today’s rapid development of science and technology, all kinds of sensors are like “behind-the-scenes heroes”, silently providing key data support for the operation of many fields. Among them, solar radiation sensors play an indispensable role in many industries with their accurate measurement capabilities of solar radiation.
Solar radiation sensors, in essence, are precision instruments used to measure solar radiation and solar energy. Its core mission is to convert the received solar radiation into other easily measured forms of energy, such as heat and electricity, with as little loss as possible. This transformation process, like a subtle energy “magic”, allows us to peer into the mysteries of solar radiation.
From the point of view of technical indicators, the solar radiation sensor shows excellent performance. The common sensor size is generally 100mm in diameter and 100mm in total height. Its test range is quite wide, can reach 0~2500W/m². In terms of sensitivity, it can reach 7~14μV/ (W · m⁻²) and the internal resistance is about 350Ω. In terms of response time, it is even faster, ≤30 seconds (99%) can complete the capture of solar radiation changes. The stability and nonlinear error are controlled at ±2%, the accuracy level reaches 2%, the cosine response is ≤±7% when the sun altitude Angle is 10°, the operating temperature characteristic range is -20 ° C ~+70 ° C, the signal output can achieve 0~25mV (if equipped with dl-2 current transmitter, Can also output 4~20mA standard signal). Such excellent performance parameters enable the solar radiation sensor to complete the measurement task stably and accurately in the complex and changeable environment.
The main driving force behind atmospheric circulation, a vital natural phenomenon on Earth, is solar radiation. Solar radiation reaches the Earth’s surface in two ways: one is direct solar radiation, which passes directly through the atmosphere; The other is scattered solar radiation, which means that incoming solar radiation is scattered or reflected by the surface. According to research, about 50% of short-wave solar radiation is absorbed by the surface and converted into thermal infrared radiation. The measurement of direct solar radiation is one of the important “responsibilities” of solar radiation sensors. By accurately measuring solar radiation, we can gain insight into the source and distribution of Earth’s energy, providing a solid data foundation for research and applications in many fields.
In practical applications, solar radiation sensors are widely used in many fields. In the field of solar energy utilization, it is a key tool for evaluating the potential of solar energy resources and optimizing the design and operation of solar power generation systems. With the data provided by solar radiation sensors, engineers can accurately judge the solar radiation intensity in different regions and different times, so as to rationally plan the location and layout of solar power plants, and improve the efficiency and stability of solar power generation. For example, in some large photovoltaic power stations, high-precision solar radiation sensors are installed, which can monitor changes in solar radiation in real time and adjust the Angle and working status of photovoltaic panels in time to maximize the capture of solar energy and improve power generation efficiency.
The meteorological field is also inseparable from solar radiation sensors. By analyzing solar radiation data, meteorologists can more accurately predict weather changes and study climate trends. As an important energy source of the Earth’s climate system, solar radiation has a profound influence on atmospheric temperature, humidity, pressure and other meteorological elements. The continuous and accurate data provided by solar radiation sensors helps scientists to deeply understand meteorological processes and improve the accuracy and reliability of weather forecasts. For example, in numerical weather forecasting models, solar radiation data is one of the important input parameters, and its accuracy is directly related to the accuracy of the model’s simulation of weather system evolution.
In the agricultural field, solar radiation sensors also play a unique role. The growth and development of crops are closely related to solar radiation, and appropriate light intensity and duration are the key conditions for photosynthesis and nutrient accumulation of crops. Agricultural researchers and farmers can use solar radiation sensors to monitor the light in the field, according to the needs of light in different growth stages of crops, take corresponding cultivation and management measures, such as reasonable dense planting, adjusting sunshade nets, etc., in order to promote the healthy growth of crops, improve the yield and quality of agricultural products.
In the aging of building materials and air pollution research, solar radiation sensors are also indispensable. Components such as ultraviolet rays in solar radiation can accelerate the aging process of building materials. By measuring the intensity and spectral distribution of solar radiation, researchers can evaluate the durability of different building materials under the action of solar radiation, and provide a scientific basis for the selection and protection of building materials. In addition, solar radiation interacts with pollutants in the atmosphere, affecting atmospheric chemical processes and air quality. Data from solar radiation sensors can help scientists study the formation mechanism and diffusion law of air pollution, and provide support for the development of effective pollution prevention and control measures.
Taking the recent industry dynamics as an example, in the 20th China (Jinan) International Solar Energy Utilization Conference and the fourth China (Shandong) New Energy and energy Storage Application Expo held from March 5 to 7, Qiyun Zhongtian Company brought self-developed photovoltaic environment high-precision monitoring equipment and full-scene intelligent solutions. Among them, the total direct dispersion integrated solar radiation monitoring system launched by the company can realize the integrated monitoring of total radiation, direct radiation and scattered radiation with a single device, and the measurement accuracy has reached the ClassA level standard, attracting the attention of many representatives of energy companies, and a number of companies have reached a cooperation intention. This case fully demonstrates the innovative application and market potential of solar radiation sensor technology in the industry.
Look at the automatic solar spectral radiation monitoring system, this intelligent solar spectral irradiator in the use of solar energy, atmospheric science research, agriculture and environmental monitoring and other fields. It uses the combination of multi-spectral filter and thermopile, which can not only accurately measure the radiation energy in different spectral intervals of the sun, but also measure the total radiation, scattered radiation and other data at the same time. The system has a number of advanced functions such as radiation data monitoring, scientific and technological acquisition instrument, wireless data storage, intelligent data operation and maintenance, self-calibration sensitivity and global tracker, providing an ideal solution for long-term solar spectral energy, solar energy resources and meteorological assessment in the field.
As a key measuring instrument, solar radiation sensor is providing strong support for human understanding of the sun, using solar energy and studying the earth environment change with its accurate measuring ability and wide application fields. With the continuous progress of science and technology, it is believed that solar radiation sensors will play a greater role in more fields and contribute to promoting the sustainable development of society. Let’s look forward to solar radiation sensors blooming more dazzling scientific and technological light in the future, helping mankind to explore more unknown areas and create a better life.
