Why solar lights are becoming more and more popular?

The solar street lamp is powered by a crystal silicon solar cell, stored energy by a maintenance-free valve-controlled sealed battery (colloidal battery), ultra-high brightness LED lamp as a light source and controlled by an intelligent charge and discharge controller. It is used to replace traditional public power lighting.No need to lay cables, no AC power supply, and no electricity costs. DC power supply and control. With good stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving, environmental protection, and fiscal and practical advantages. It can be widely used in urban primary and secondary roads, communities, factories, tourist attractions, car parks, and other places. Product lamp pole structure composition: steel lamp pole and bracket. Surface spraying treatment and battery board connection using special anti-theft stainless steel screws.

The solar street light system can guarantee standard operation for more than 15 days in rainy weather! Its system composition is composed of the LED light source, solar panel, battery, solar street light controller, street light pole and auxiliary material wire, and other parts.

Installation comparison.

When installing solar street lights, there is no need to set up complicated wiring. Just make a concrete base, make a battery pit, and then fix it with galvanized bolts.

It does not need to consume power, material, and financial resources.

Cost comparison.

Solar street lights are a one-time investment with long-term benefits because the wiring is simple, there are no maintenance costs, and no expensive electricity is generated.6-7 years to recover the cost, 3-4 years to save more than 1 million electricity and maintenance costs.

It saves the high electricity cost of a street lamp, the tedious line, and the long-term uninterrupted maintenance of the line. Especially in the case of unstable voltage, sodium lamps inevitably fail, and with the extension of life, line aging and maintenance costs increase year by year.

Security comparison.

Solar street lights are ideal for ecological communities and highway departments because they use a low voltage of 12-24V, are stable, operate reliably, and have no safety hazards.

The municipal electric street lamp is a crucial safety hazard. People’s living environment is constantly changing road transformation, landscape engineering construction, abnormal power supply, water supply, gas pipeline cross construction, and many other aspects bring many hidden dangers.

Environmental comparison.

Solar street lamps can add new selling points for the development and promotion of noble ecological communities; They can sustainably reduce property management costs and shorten public sharing costs for owners. To sum up, the inherent characteristics of solar lightings, such as no hidden danger, energy saving, green environmental protection, easy installation, automatic control, and maintenance free, will directly bring visible advantages for property sales and municipal engineering construction. The solar lamps work automatically and do not require trenching and wiring, but the poles need to install on pre-built parts (concrete bases).

LED light source

1. High luminous efficiency, low power consumption, long service life, and low working temperature.

2. High safety and reliability.

3. Fast response time, small unit size, green and environmental protection.

4. Under the same brightness, the power consumption is one-tenth of incandescent lamps, one-third of fluorescent light, but the life is 50 times of incandescent lamps, 20 times of fluorescent lamps. It is the fourth generation of lighting products after incandescent light, fluorescent lamps, and gas discharge.

Battery component holder

1) Tilt angle design

For the solar module to receive as much solar radiation as possible during the year, we have to choose an optimal tilt angle for the solar module. The question is the optimum tilt angle for solar modules is discussed and used in different regions depending on the area.

2) Wind-resistant design

In the solar street light system, a structural issue that requires great attention is the wind resistance design. Wind resistance design is mainly divided into two blocks, one for the wind resistance design of the battery module rest. And the other is for the wind resistance design of the light pole. The following is an analysis of each of these two blocks.

(1) Wind resistance design of solar cell module support

According to the technical data of the module manufacturer and the wind pressure that the solar module can withstand is 2,700 Pa. If the wind resistance factor is selected as 27m/s (equivalent to a typhoon of class 10), according to non-viscous fluid mechanics, the wind pressure that the module can withstand is only 365 Pa. Therefore, the module itself is fully capable of withstanding a wind speed of 27m/s without damage. Therefore, the crucial consideration in the design is the connection between the battery module holder and the light pole.

Controllers

The primary role of the solar charge/discharge controller is to protect the battery. The function must have overcharge protection, over-discharge protection, light control, time control, anti-reverse connection, charge trickle protection, under voltage protection, waterproof protection, etc. The general parameters of the battery protection against overcharge and over-discharge voltage are shown in the table.

1) Device selection

In the selection of devices, there is currently the use of microcontrollers. There is also the use of comparators and more programs, each with its characteristics and advantages. Should be selected according to the needs of the customer group characteristics of the corresponding program. Here is not detailed.

2) Surface treatment

The series of products adopt new technology of electrostatic coating, mainly FP professional building materials coating, which can meet the customer’s requirements for product surface color and environmental harmonization. While the products have high self-cleaning and strong corrosion resistance. And aging resistance and are suitable for any climatic environment. The processing process is designed to be painted based on hot dip zinc, which makes the product performance greatly improve to meet the most stringent requirements, and other indicators have met or exceeded the relevant necessity of GB.

3) Charging trickle protection

When the EJIA solar panel charges the battery after the battery reaches the peak voltage, if it continues to law at a high electric element, it is easy to cause the battery to lose water or lose control; if it stops charging, the battery cannot be saturated again. This controller in charge immediately after the peak voltage will cut one v voltage and then enter a trickle charging status. To ensure the batteries are in a stable state, avoid water loss or out of control, like the battery charging circuit, which not only effectively protects the electric element. But also increased the number of the battery, to prolong the service life.

Installation Comparison

When installing solar street lights, there is no need to set up complicated lines, make a concrete base, make a battery pit, and fix it with galvanized bolts. No need to consume a lot of manpower, material, and financial resources.

Cost Comparison

The solar street light is a one-time investment and a long-term behalf. Because the line is simple, does not produce maintenance costs, and does not produce expensive electricity. 6-7 years to recover the spend, 3-4 years to save more than 1 million electricity and maintenance costs.

It can save the high electricity cost of the primary street light, the complicated lines, and the need for long-term uninterrupted maintenance of the lines. Especially in the case of unstable voltage, the sodium lamp inevitably breaks down, and with the extension of the years, the line aging, maintenance costs are increasing every year.

Safety Comparison

Solar street lights are ideal for ecological communities and highway departments because they use 12-24V low voltage, stable voltage, reliable operation, and no safety hazards.

Municipal electric street lights are a material safety hazard, people’s living environment is constantly changing. And road reformation and construction of landscape projects. The power supply is not regular water and gas pipelines cross construction and many other aspects bring many hidden dangers.

Environmental protection comparison

Solar street lights can add new selling points to the development and promotion of noble ecological communities; they can sustainably reduce property management costs and weaken the owners’ public share of the costs. In summary, the inherent characteristics of solar lighting, such as safety without hidden dangers, energy saving without consumption, green environmental protection, easy installation, automatic control, and maintenance-free, will bring obvious advantages to the sales of properties and the construction of municipal projects directly.

Solar street light working principle description: solar street light in the daytime under the control of an intelligent controller, solar panels after the sun’s irradiation, absorb solar light and converted into electricity, solar cell components to the battery pack charging during the day, the battery pack at night to provide power to the LED light source power supply, to achieve the lighting function.
