How to Improve the Illumination Effect When Installing Solar Street Light?

With the continuous development of solar power generation technology, solar street lights have become a new favourite in the city's road lighting industry due to their environmental protection and energy-saving advantages, with huge market potential. In terms of energy saving, solar street light does not consume conventional electricity. The power consumption of conventional street lights accounts for 30% of the total lighting power consumption in the country. So how can we achieve better lighting effects when installing solar street lights? Let's take a look at this issue below.

Selection of inclination angle of a solar panel for solar street light

The ideal inclination angle is to maximize the power generation of the solar panel for solar street lights and minimize the difference in power generation between winter and summer.

In general, when local size or latitude is added a few degrees as the inclination angle of the local solar street light solar cell module installation, there is a significant difference in horizontal solar radiation between high latitude winter and summer.

If the cell is designed according to the horizontal radiation parameter, the storage capacity of the cell will be too large in winter, leading to an increase in the design capacity and investment of the cell.

When a better inclination angle is selected, the radiation on the solar cell panel in winter and summer will differ less, and the cell capacity can also be reduced, thereby reducing the cost of the entire solar street light lighting system and making the design more reasonable.

Selection of azimuth angle of solar cells for solar street light

The azimuth angle of the commonly used solar street light is generally facing south so that the solar cell panel can generate a large amount of power in unit time. If the solar street light is installed on a roof, a slope, in a mountainous area, a building structure, or restricted by shadows, we need to consider fully utilizing the existing terrain and effective area to avoid shadows caused by surrounding buildings and trees, so that the efficiency of light conversion is relatively low.

Selection of angle and area of solar cell for solar street light

In the northern hemisphere summer, as long as it is within ±20° to the south, if conditions permit, in the case of southwest 20°, it will not have a great impact on power generation, making the peak of solar power generation appear after noon. There are more optional angles in winter. If the south side solar cell area is not large enough, consider laying solar cell panels in the east-west direction.
