Embodiment

[0092] Take n=4, when φ sun =226.156, θ sun =60.51, the installation angles of the four solar radiation measuring instruments are 150°, 0°, 30°, and 60° respectively. The readings of the four solar radiation meters are 614.1W / m 2 、853.9W / m 2 、937.9W / m 2 , 842.8W / m 2 . The light radiation intensity of each part calculated through steps 1-3 is direct radiation DNI=668.6W / m 2 , scattered radiation DHI=272.0W / m 2 , ground reflection GAI=256.2W / m 2 .

[0093] The solar energy conversion component is a solar double-sided module, and the angle with the horizontal is 20 degrees.

[0094] c 1 =0.21; when the scattered radiation DHI is on the front of the solar panel of the solar energy conversion component, When the scattered radiation DHI is on the opposite side of the solar panel of the solar conversion component, When the ground reflects GAI on the front of the solar panel of the solar conversion component, When the ground reflection GAI is on the opposite side of th...
