Description
Technical Field
The invention relates to a high-efficiency solar panel rotation control method, and belongs to the technical field of solar power generation.
Background
Solar energy is a new clean energy source, mainly a solar panel, and in order to make full use of the solar energy, it is very important to select the best azimuth angle and inclination angle of the solar panel matrix.
The azimuth angle of the solar cell panel square matrix is an included angle between a vertical plane of the square matrix and a positive south direction (an east deviation is set as a negative angle, and a west deviation is set as a positive angle). In general, when the square matrix faces south (i.e., the included angle between the vertical plane of the square matrix and the south is 0 °), the solar power generation amount is the largest. When the temperature deviates 30 degrees from the true south (northern hemisphere), the power generation amount of the square matrix is reduced by about 10-15%; at 60 ° off the true south (northern hemisphere), the power generation of the square matrix will be reduced by about 20% to 30%. The solar cell panel matrix is installed by considering the whole week and slightly adjusting, and specific problems are specifically analyzed. It is desirable to avoid the shadowing of solar shadows like houses, trees, etc. The following formula may be referenced: the azimuth angle is (peak time of load in one day (24 hours) — 12) × 15+ (longitude-116).
The inclination angle is the angle between the plane of the solar cell array and the horizontal ground, and the angle is the optimal inclination angle when the power generation amount of the array is the maximum in one year. While the optimum bank angle is related to the local geographical latitude, if the local latitude is higher, the corresponding bank angle is also large. The problem of the inclination angle of the accumulated snow falling is also considered, and the solar energy matrix energy is maximized. The azimuth angle and the inclination angle of a certain solar cell panel matrix are designed in detail, and the azimuth angle and the inclination angle are comprehensively and further considered in combination with the actual situation.
In the prior art, a solar cell panel matrix is usually fixed on a mounting seat, and although the maximum power generation amount at a fixed angle can be obtained by setting an optimal inclination angle, no good control method is provided.
