N is a radical of₀79.6764+0.422 (year-1985) -INT [ (year-1985)/4 ×]I.e. the angle of day theta is related to the year and date.

The solar declination angle δ can be expressed by the following formula:

δ＝0.3732+23.2567sinθ+0.1149sin2θ-0.1712sin3θ-0.758cosθ+0.3656cos2θ+0.0201cos3θ；

the running speed of the sun on the ecliptic is not constant all the time, the length of the real sun is different, the hypothetical sun runs at a constant speed, the time of the hypothetical sun for two consecutive middle days is called as an average sun day, and 1/24 of the average sun day is the average sun time; the day of the true sun is different from the day of the ordinary sun, and 1/24 of the true sun is true sunTime difference between true and flat times E_tRepresents:

S₀＝S+E_t；S₀true sun, S is flat sun. Time difference E_tCan be expressed by the following formula:

E_t＝0.0028-1.9857sinθ+9.9059sin2θ-7.0924cosθ-0.6882cos2θ；

height of the sun h₀Can be calculated by the following formula:

wherein delta is the declination angle of the sun,

the geographic latitude provided for the positioning system module 8; tau is the local solar hour angle;

τ＝(S₀+F₀60-12). times.15 °; wherein S is₀When it is true sun, F₀True sun score, 1/60 when true sun.

Calculating true solar time S₀Converting Beijing time expressed by the flat solar time S into local time S_d：

S_d＝S+{F-[120°-(JD+JF/60)]×4}/60；

Wherein S is the current hour of the Beijing time expressed by the Pingtang time, and F is the current minute of the Beijing time; JD is the local longitude, JF is the local longitude score; 120 degrees is the standard precision of Beijing time, and multiplying by 4 is to convert the angle into time, namely each degree is equivalent to 4 minutes; divide by 60 is to change minutes to hours;

then for local time S_dMaking time difference correction, S₀＝S_d+E_tA/60; when real sun is corrected in real time, the difference S is used₀Calculating local solar time angle tau and solar height h₀。

The local solar altitude h is obtained₀Afterwards, the solar azimuth angle a is calculated:

the solar azimuth angle A has two values, when cosA is less than or equal to 0, A is more than or equal to 90 degrees and less than or equal to 180 degrees; when cosA is more than or equal to 0, A is more than or equal to 0 and less than or equal to 90 degrees, and the latter A value is 360-A. The corresponding position of the first photovoltaic panel 25 can be adjusted by the solar azimuth angle and the solar height, so that the first photovoltaic panel is just opposite to the irradiation direction of the sun. The present invention uses the solar track based on time and latitude and longitude to achieve the tracking function of the first photovoltaic panel 25. At night, such as midnight zero, the following unit 6 drives the first photovoltaic panel 25 to return to the initial position, such as the horizontal position, and after waiting for the sun to rise next day, tracking power generation is performed again.
