Sunlight shadow simulation device of solar array

Abstract

The invention relates to a sunlight shadow simulation device of a solar array, comprising an equator fixing plate, an hour angle turntable model plate, a solar array model plate, a geographical coordinate plane model plate and a parallel light source. The hour angle turntable model plate is arranged on the equator fixing plate and rotates around a rotating shaft perpendicular to the equator fixing plate, the solar array model plate is arranged on the geographical coordinate plane model plate which is arranged on the hour angle turntable model plate, the solar array model plate and the hour angle turntable model plate can singly rotate, the rotating shafts of the solar array model plate and the hour angle turntable model plate are mutually parallel, the geographical coordinate plane model plate and the array model plate rotate together along the hour angle turntable model plate, an included angle between the geographical coordinate plane model plate and the equator fixing plate is the complementary angle of the latitude of a simulation site, an included angle between the solar array model plate and the geographical coordinate plane model plate is equivalent to an included angle between the solar panel on a simulation site and the ground, and an included angle between parallel light emitted by the parallel light source and the equator fixing plate is preset according to experimental requirements.

Description

technical field [0001] The invention relates to a solar battery array sunlight projection simulation device. Background technique [0002] For existing sand table model devices, all are fixed models under a certain light environment. As for the active sand table model projection, it is limited to the form of software simulation, and it is set up for the demonstration of architectural functions. There is no precise scale, and it cannot be measured. Obviously, the factors considered by the two are different. The similar ones are only models, and the light environment is different, and the purpose is also different. One is presentation and the other is measurement. Contents of the invention [0003] This application provides a novel device for simulating the projection of sunlight on a solar cell array. [0004] The design principle of this device: the tangent plane coordinates of a point on the earth are defined as the geographic coordinate plane. According to the releva...
