Description

technical field [0001] The invention relates to the field of new energy, in particular to a solar radiation testing method and system thereof. Background technique [0002] With the rapid growth of photovoltaic system installation capacity, the photovoltaic system operation evaluation system has gradually been established, the most important point of which is the photovoltaic system efficiency evaluation. Photovoltaic system efficiency generally refers to the ratio of actual power generation output to the total amount of radiation reaching the surface of the photovoltaic array. Accurate and rapid measurement of radiation is crucial to the evaluation of photovoltaic system efficiency. [0003] Current solar radiation sensors used for efficiency assessment of photovoltaic systems usually consist of a combined thermopile circuit with a black lacquered receiver on the sensor and a hemispherical glass dome on the bottom. This type of total solar radiation sensor can reflect the ...
