What should be paid attention to when installing led solar street light panels?

>

For led solar lighting.com/street-lighting' target='_blank'>street lights, I believe everyone can see them in daily life. The led solar street light mainly receives light through the battery panel, so as to realize the photoelectric conversion on the back and successfully light the light source. If the panels are not installed correctly, the desired lighting effect may not be achieved.

1. Wire requirements

First of all, LED solar street light manufacturers recommend using insulated copper wire instead of aluminum wire. It is superior to the latter in terms of electrical conductivity and resistance to galvanic corrosion, and it is not as flammable as aluminum wire. It is very efficient to use. and higher safety factor.

Secondly, the polarity of the wiring is different, and the color is different, which is convenient for installation and maintenance; the connection is firm, do not increase the contact resistance, and the wire is as short as possible, which can reduce the internal resistance of the line and ensure its work efficiency.

The insulating winding layer of the joint part should be considered to meet the insulation strength and weather resistance requirements; in addition, according to the ambient temperature during installation, the temperature parameters of the wire should have a certain margin.

2. Find the positive and negative poles

First of all, be sure to figure out the positive and negative poles of the battery board. When making a series electrical connection, the '+' pole plug of the previous element is connected to the '-' pole plug of the next element, and the output circuit must be properly connected to the device.

Don't get the polarity wrong, otherwise the battery board may not be able to charge and the controller indicator light will not light up. In severe cases, the diode will be burned out, which will affect the service life of the battery panel. LED solar street light manufacturers should avoid wearing metal accessories when installing solar panels, and avoid the positive and negative electrodes of the solar panel from contacting metal objects, resulting in short circuit, or even fire or explosion.

3. The orientation of the solar panel

In order to ensure the charging efficiency of the led solar street light, the solar panel must receive sufficient sunlight to achieve a large amount of power generation per unit time, and the orientation is due south, that is, the direction with high solar radiation intensity.

However, due to the limitation of objective conditions such as the surrounding environment or construction, there may be no way to accurately locate this direction. Don't worry, it is generally within the range of ±20°. Due to the south, it will not have a great impact. : 00 to 16:00 to receive sunlight.

If the demand for light cannot be met, it can be compensated by increasing the power of the solar panels.

Fourth, the tilt angle of the solar panel

In addition to the orientation of the LED solar street light panel, the tilt angle is also the key point to pay attention to during installation. This parameter is mainly determined according to the local latitude. Generally speaking, the closer to the north, the larger the angle, and the closer to the south, the smaller the angle.

Generally speaking, when the local latitude is 0°~25°, the elevation angle is the same as the latitude. When the latitude is 26°~40°, add 5°~12° on this basis, and when the latitude is 41°~55°, add 10°~15° to the inclination angle. If the latitude is above 55°, it is more appropriate to add 15°~22°.

5. Install lightning protection device

When installing the battery board, you should also pay attention to the installation of lightning protection devices, which are especially suitable for cities with many thunderstorms. Otherwise, lightning strikes nearby will easily cause overvoltage and overcurrent, and the back of the battery will be damaged by lightning strikes.

Generally, the dedicated photovoltaic power SPD is installed in the DC power distribution cabinet (combiner box), and the battery panel is equipped with equipotential grounding and direct lightning protection.

Whether it's automation or artificial intelligence, the rapid convergence of technology and business often determines led light fixtures’s competitiveness.
