In order to address the problem of how to simulate the sunlight dynamically and accurately in utilization of the solar energy technology,an all-weather indoor solar simulator was simulated on the basis of orbital parameters.According to the static trajectory data,it simulates the all-weather solar illumination,and checks the degree of approximation of the real-time detection of xenon lamp and of the spectrum of the sun.The experimental results show that in this solar simulator,the wavelength of the source and spectral of xenon lamp spectrum after dealing with the mismatch error can meet the requirements of GBPT12637-90's A level,and the irradiance of the sun simulator is between 0~1 600W/m2,with an average irradiance of 1 000W/m2,the intensity of illumination is between 0~65 000 lux,the effective radiation area is 400cm2,and the dynamic simulation deviation is 4.3%.As a whole,this device basically realizes allweather simulation of the solar illuminance,which has certain reference significance to the development of simulation technique.
