Yes, if the tilt angle of your module array is fixed, the average optimal tilt angle from January to December is usually taken into account. If it is sun tracking or odd-even tracking method, the tilt and elevation of the module array will always maintain the optimal tilt and elevation operating mode from January to December , and the efficiency of electricity generation will be maximized.
What is the best direction for solar panels?
1. Shine the sunlight as vertically as possible onto the energy absorbing plane.
2. The sun is in the sky at 12 o'clock on the summer solstice. At this time, the sun's rays are not vertical to the ground. The further away from the equator, the greater the inclination. corner. The plane absorbing the energy must be perpendicular to the sun's rays (due to the size of solar energy). The formation of an angle d'tilt with the horizontal plane can absorb more solar energy;
3. Geometric principles, generally the normal line of the energy absorbing surface (perpendicular to the energy absorbing surface) is aligned with the sun's rays at noon. They simply coincide with the influence of fog in the morning. , the best time is 1:00 p.m. in the south.
It is preferable that the solar panels face south.
Solar panels should face the sun and get the most sunlight. The azimuth angle of the panels on common solar street lights in life is generally chosen to be in the south direction, which can optimize the power output of solar panels per unit time if the solar street lights are installed in places such as roofs. slopes, mountains and building structures. When considering restrictions on shadows, etc., you need to think carefullyr how to make full use of the existing land and effective area, and try to avoid shadows generated by surrounding buildings, structures or trees.
As long as it is ±20° due south, it will not have a big impact on electricity production. If conditions permit, it should be as far as possible within 20° southwest to allow peaking. of solar energy production will appear around noon, which will make it possible to produce more electricity in winter. When the installation area of solar panels in the south direction is not large enough, the solar panels can also be installed in the east and west directions.
Selection of the tilt angle of the solar panels:
The ideal tilt angle is to make the annual energy production of the solar panels for public lighting as large as possible, so that in winter the difference in production of electricity between summer and summer is as small as possible. Generally, local latitude or local latitude plus a few degrees is used as the tilt angle for local installation of solar cell module. (Generally, the tilt angle is 30 degrees in areas south of the Yangtze River and 45 degrees in areas north of the Yangtze River.)
Of course, if software Computer aided design can be used, the Solar tilt angle optimization calculation can be carried out, it would be better to be able to take both into account, which is particularly important for high latitudes. There is a very large difference in horizontal solar radiation between winter and summer at high latitudes.
If the design is based on horizontal plane radiation parameters, the storage capacity of the battery in winter will be too large, resulting in an increase in ACpacity of battery design and investment. When the optimal tilt angle is selected, the difference between the winter and summer radiation of the solar panel becomes smaller and the battery capacity can also be reduced. A balance is found, which reduces the cost of the entire solar street lighting system. Low, the design is more reasonable.
