The R photovoltaic solar radiation observation station is mainly used to monitor solar radiation energy data and add solar radiation measurement to the base surface of the R-type photovoltaic environmental monitor. For example: the system combination of total solar radiation, direct radiation, scattered radiation and reflected radiation. It is used by various meteorological departments to monitor local solar resources, provide first-hand information for research on solar meteorology, agriculture, ecological environment, and oceans, and provide first-hand information for station construction in the power industry, solar power station site selection, agricultural meteorology, plant physiology research, oceanographic investigation, aging of building materials, and air pollution, etc. Research. Main test indicators:
Total radiation:
The total irradiance (/) of direct sunlight and sky scattering with a wavelength of ~ received within a solid angle on a horizontal surface. The pyranometer is composed of sensing parts and glass cover accessories. Its working principle is based on the thermoelectric effect, and the sensing element consists of a sensing surface and a thermopile. The thermopile is a fast-response wire-wound electroplated thermopile, and the sensing surface is coated with matte black paint. When the black-coated sensing surface receives radiation and heats up, the thermopile with the thermal contact close to the lower part generates a temperature difference electromotive force output signal that is proportional to the received irradiance.
The glass cover is hemispherical double-layer quartz glass, which prevents wind and transmits short-wave radiation in a range of wavelengths. The transmittance is constant and close to the same. The double-layer cover is used to prevent the influence of infrared radiation from the outer cover and reduce measurement errors.
Accessories include: body dryer white baffle base level and terminal posts, etc. There is also a metal cover (also called a hood or protective cover) that protects the glass cover.
Direct radiation:
Measurement of radiation perpendicular to the solar surface (viewing angle approx.) and scattered radiation in a very narrow ring of sky around the sun is called direct solar radiation. Direct solar radiation is measured with a pyrheliometer (referred to as a pyrheliometer or pyrheliometer). (Sunshine hours: the sum of the time periods when direct solar radiation reaches or exceeds one square meter, in hours, with one decimal place taken)

Reflected radiation,
The total solar radiation sensor is equipped with a special connecting rod, so that the sensing surface is downward, used to measure the wavelength of ~ short-wave reflected radiation from the ground
