The angle of the solar cell for solar power system
|If there are no conditions for computer optimization of the tilt angle, the tilt angle of the solar cell can be roughly determined according to the local latitude:
When the latitude is 0 ~25 degrees, the inclination angle is equal to the latitude.
When the latitude is 26 ~40 degrees, the inclination angle is equal to the latitude plus 5 ~10 degrees.
When the latitude is 41 ~55 degrees, the inclination angle is equal to the latitude plus 10 ~15 degrees.
When the latitude is above 55 degrees, the inclination angle is equal to the latitude plus 15 ~20 degrees.
But different types of solar photovoltaic power system, the optimal tilt angle is different. Such as light controlled solar street lighting system and other seasonal power supply photovoltaic power generation system. The working time of such load varies with season, and its characteristics depend on natural light to determine the working time of load. In winter, the sunshine time is short, the energy of solar radiation is small, and the working time of the load at night is long, and the power consumption is great. Therefore, when designing the system, we should take care of the winter and determine the tilt angle of the maximum power output in winter, and the inclination angle should be larger than the local latitude angle.
This can also be applied to solar aviation obstruction lights.
