Working principle and installation precautions of solar panel street light

Introduction
With the improvement of environmental awareness, solar panel street light are more and more widely used in urban and rural public places. It is a device that uses solar panels to convert solar energy into electricity for street lighting.
Composition and working principle of solar panel street light
The composition and working principle of solar panel street light: solar street lights are mainly composed of solar panel components, smart controllers, battery packs, street lights, light poles and supports. Solar panel street light use solar panels to convert solar radiation into electricity during the day, and then the energy is stored in the battery through an intelligent controller.
When the night comes, the sun light intensity gradually decreases, when the smart controller detects that the illuminance decreases to a certain value, it controls the battery to provide power to the street lamp load, so that the street lamp will automatically light up when it is dark. The controller protects the charging and discharging of the battery, and controls the opening and lighting time of the street lamp.
Installation precautions of solar panel street light
Because solar panel street lights are products that rely on sunlight to work, when installing, we must ensure that its absorption of light energy needs to be as thorough as possible, and when wiring, we need to ensure the smooth flow of the line in the future work, so when we install solar street lights, we should pay specific attention to the following points:
Pay attention to the best inclination angle of the solar panel
The panels of solar street lights have an optimal angle, which is to ensure that the panels can absorb the most sunlight, and this Angle is related to the local alatitude and longitude. When installing solar panel street lights, you first need to confirm this angle.
Pay attention to whether there is a shelter above the solar panel
If there is a shelter above the panel, such as leaves, buildings, etc., resulting in a shadow on the solar panel during the day, because the solar panel is generally multiple pieces in series, if the solar panel a string of cells appear on the shadow, the shadow is relatively deep, serious, this string is equivalent to a break, then the solar panel will not generate electricity.
This will reduce the absorption and utilization of sunlight by the panels, resulting in a decrease in the charging efficiency of the solar panels, which is not conducive to the conversion of light energy to electric energy. As a result, the streetlight led time is very short or can not be lit. In order to avoid the problem that the street light is not bright or the lighting time is short, the installation of solar street lights needs to choose an empty area, and there is no shelter above the panel.
Pay attention to the street light nearby
There are other street lights next to the solar street lamp, and the street light is on next to it, resulting in the solar panel of the solar street lamp detecting the light source mistakenly thinking that it is daytime, and the charging voltage of the solar panel is above the photo-controlled voltage point, and the light cannot be lit.
Pay attention to the wiring sequence of solar panels, controllers, batteries and street lights.
Do not connect the positive and negative terminals incorrectly. The models and specifications of components such as solar panels, batteries, controllers or inverters need to be selected according to the specific installation site and the power of the luminaires. During the installation process, it is necessary to ensure that the connection of each component is correct, and pay attention to protect the surface of the solar panel is clean and not damaged.
The installation height of solar panel street light
The height of the street lamp directly affects the scope and effect of the lighting. If the street lamp is too high, the lighting range is too large, it will cause light pollution and energy waste; If the street lights are too low and the lighting range is too small, it will not be able to meet the needs of road lighting. Therefore, when choosing the height of the street lamp, it is necessary to choose according to the actual situation of the road and the traffic flow.
Battery capacity of solar panel street light
The battery is an important part of the solar street lamp, which is responsible for storing electrical energy and providing electricity when needed. The larger the capacity of the battery, the longer the street lamp can continue to light. However, the capacity of the battery also depends on the electricity that the solar panel can provide, so it is necessary to choose a matching solar panel according to the battery capacity. Currently commonly used batteries are: lead-acid batteries, colloidal batteries, lithium batteries.
Pay attention to the local sunshine time, weather and others
Before installing solar street lights, it is necessary to understand the local sunshine time and weather conditions in order to better choose the configuration and specifications of street lights. At the same time, it is necessary to take into account the local culture and habits, street lighting working hours, in order to better meet the lighting needs.
In short, the installation of a solar street lamp needs to consider many factors. Only with adequate planning and preparation can we ensure that solar street lights can work normally and stably, bringing convenience and environmental protection to people’s lives.
Advantages of solar panel street light
Green environmental protection: Solar street lights use solar energy to generate electricity, without fuel, and do not produce pollutants or greenhouse gas emissions. They are environmentally friendly and help reduce the consumption of limited resources.
Economy and energy saving: The energy source used by solar street lights is solar energy, free and unlimited. They can collect solar energy during the day and use it at night, thus avoiding reliance on traditional power grids. This can save money on electricity bills and reduce the need for conventional electricity.
Highly reliable: solar street lights are usually composed of photovoltaic panels, batteries and LED street lights. Their simple structure, no complex wiring and vulnerable parts, so very reliable. Solar street lights have a long life and low maintenance costs.
Automatic switch: solar street lights are usually equipped with light-controlled switches, which can automatically switch according to the brightness of the light. In the night or cloudy days, the lamp will be automatically lit; The lights turn off automatically during the day or when the light is bright enough. This automatic switching function makes solar street lights very convenient and does not require manual operation.
Increase safety: the brightness of solar street lights can be adjusted according to needs, and usually has a high lighting effect. The use of solar street lights in areas such as roads, sidewalks, parking lots, and public squares can provide good lighting effects and increase the safety of pedestrians and vehicles.
Flexible installation: solar street lights do not need wiring, can be installed independently and move at any time. They are suitable for remote areas, where there is no electricity supply or where wiring is difficult. The installation and maintenance of solar street lights is relatively simple, and can be adjusted according to actual needs.
Summary
In summary, solar street lights have many advantages such as green environmental protection, economic and energy saving, highly reliable, automatic switching, dimming, flexible installation and so on. With the continuous development of solar energy technology, solar street lights are more and more popular and applied by people. Contact us for more information about solar led street lights.
