Application of solar radiation in various fields

Energy field

Solar power station related

Evaluating the potential of solar energy resources helps determine whether a region is suitable for building a solar power station and the approximate power generation capacity after the power station is built. For example, in some desert areas with sufficient sunlight, solar power stations are developed and built in large quantities after the evaluation of solar radiation.

Optimize the layout of photovoltaic power stations, and reasonably arrange the position and orientation of photovoltaic panels according to the distribution law of solar radiation to improve power generation efficiency. For example, in the northern hemisphere, photovoltaic panels usually face due south to receive more solar radiation.

Carry out power forecasting, through monitoring and analysis of solar radiation, predict the power generation of solar power stations at different times, which is convenient for grid dispatching and other work. This is because changes in solar radiation intensity will directly affect the power generation of photovoltaic power stations.

Meteorological research field

Meteorological forecasting

Monitoring the intensity of solar radiation. Solar radiation is the energy source of the atmospheric system. Its intensity changes will affect meteorological elements such as atmospheric temperature and humidity, thereby providing important basic data for meteorological forecasting. For example, when predicting temperature changes, the intensity of solar radiation is an important reference factor.

Studying climate models, the long-term trend of solar radiation has a profound impact on the climate. Through the study of solar radiation, we can better build and improve climate models to predict future climate change trends.

Construction field

Evaluation of building material performance

Test the weather resistance of materials. Ultraviolet rays and other components in solar radiation will have aging effects on building materials. Through testing with equipment such as solar radiation detectors, we can evaluate the impact of long-term solar radiation on material performance, so as to select more suitable building materials. For example, some paints used outdoors need to undergo solar radiation-related tests to ensure their service life.

Sunlight analysis in building planning. When designing buildings and planning cities, it is necessary to consider the sunlight conditions of buildings to meet the lighting needs of residents and avoid shading problems. This involves the analysis of factors such as the angle and duration of solar radiation. For example, when determining the distance between residential buildings, it is necessary to calculate based on the local solar radiation conditions to ensure the lighting rights of the residents on the ground floor.

Agricultural field

Crop planting related

Choose the best planting location for special crops. Some crops have special requirements for sunshine. Understanding the sunshine in a specific geographical location helps to choose the best planting location for special crops that require special microclimate conditions to achieve optimal growth. For example, some sun-loving flowers need to be planted in places with sufficient sunshine.

Affects the growth and development of plants, the yield and geographical distribution, because the spectral composition, illuminance and illumination time of solar radiation will affect the use of solar energy by plants, thereby affecting the growth of plants. For example, in areas with sufficient sunlight, some fruits may be sweeter and have higher yields.

Atmospheric environment monitoring field

Assessment of atmospheric transparency and pollutant impact

Assist in evaluating the scattering and absorption effects of atmospheric pollutants on solar radiation. Pollutants in the atmosphere will change the transmission process of solar radiation in the atmosphere. By monitoring the changes in solar radiation, the concentration and distribution of atmospheric pollutants can be understood. For example, in haze weather, the intensity of solar radiation will be significantly weakened.

Monitor atmospheric transparency. Changes in the intensity of solar radiation can reflect the transparency of the atmosphere, which is of great significance for understanding the physical state of the atmosphere and environmental quality.

The working principle of carbon dioxide detector

图片
The working principle of carbon dioxide detector The working principle of the CO2 detector is mainly based on the infrared light source absorption principle. The following is the detailed working mechanism: Infrared absorption principle: Carbon dioxide detectors detect carbon dioxide gas in the environment through the absorption properties of infrared light sources. Specifically, carbon dioxide molecules have absorption properties for infrared light of specific wavelengths, especially infrared light with a wavelength of approximately 4.26 microns (4260 nanometre ). Measuring chamber and light source: The gas to be measured is introduced into a measuring chamber with an infrared light source mounted at one end of the chamber and a filter and detector at the other end. The filter allows infrared light of a specific wavelength to pass through, while the detector measures the luminous flux through the chamber. Detector Measurement: The amount of light flux received by the detector depends...

  The Importance of Weather Forecasting Weather forecasting has an extremely important impact on our daily lives, economic activities and social security. The following are some of the main aspects: 1. Prevention of natural disasters Weather forecasts can predict possible weather disasters in advance, such as heavy rain, typhoons, snowstorms, etc., so as to take appropriate precautions to reduce the loss of life and property.   2. Planning life and production activities People can understand the future weather changes through the forecast, reasonable planning of travel, tourism, outdoor activities, etc., to improve the convenience and safety of life. For agricultural production, weather forecasts can provide farmers with references for agricultural activities such as sowing, fertile  application, irrigation, etc., so as to improve the efficiency of agricultural production and yield.   3. Emergency response When emergencies occur, such as epidemics, earthquakes, etc.,...
