1. What is a solar street light working principle?

The working principle of solar streetlights is: that under the control of the intelligent controller, the solar panel absorbs solar light during the day and converts it into electrical energy to charge the battery pack. At night, the battery pack provides power to the LED light source to realize the lighting function. The excess electricity can be stored to ensure normal operation in rainy weather.

3. 6 Factors affecting the price of solar street lights:

a. Lamp pole shape. For example, municipal street lights have some shapes and require longer working time. Therefore, the shape of the lamp pole will affect the price. Especially for some government projects, the price difference will be greater;

b. Full power working time. Normal solar streetlights will set the energy-saving mode according to the traffic flow curve, which can save power consumption and reduce the configuration of the solar system. However, if the full power working time is required to be high, such as 6 hours of 100% brightness and 6 hours of 50% brightness, the price will increase a lot.

c. Number of lamp heads. If it is made into double lamp heads, triple lamp heads, etc., the solar panels and lithium batteries will increase exponentially, and the diameter and wall thickness of the lamp pole will also be larger to meet the wind resistance requirements. Calculated in that way, the price is completely different.

d. Average illumination, uniformity, and luminous flux maintenance number. The international urban road lighting standards have clear numerical requirements for average illumination, uniformity, and luminous flux maintenance numbers for roads and intersections of different levels. For example, the average illumination of a first-class road should reach 30-30LUX, with a uniformity of 0.4; the second-class road should reach 15-20LUX, with a uniformity of 0.4.

To achieve this requirement, the light efficiency, power, and light distribution of the lamps must be taken into consideration. The actual driving power of the lamp is large, and the solar panels and lithium batteries are configured larger. The unit price is naturally higher.

e. Wind resistance level requirements. Normal municipal engineering requires a wind resistance level of 12 or above. The requirements in various places are slightly different. In addition, the large area of ​​solar panels and the weight of large lithium batteries require the caliber, wall thickness, and flange size of the lamp pole to be larger. Naturally, the price will be higher.

f. Warranty period requirements. Municipal engineering must have a certain proportion of the final payment to be accepted and paid off. In addition, a certain proportion of the warranty deposit must be reserved, and this warranty deposit can generally be collected after the warranty period expires. The requirements for municipal engineering are relatively high, and the warranty period is also relatively long. Therefore, to reduce after-sales costs, manufacturers often add after-sales costs to the quotation in advance. This directly raises the price of solar streetlights.

4. How to choose a cost-effective solar street light

1. Detailed configuration

The cost-effective solar street light must have a reasonable configuration. The basic configuration of the solar street light mainly depends on the power of the lamp, the capacity of the battery, the size of the solar panel, the material of the lamp pole, etc. These parameters should be paid attention to, and avoid buying products with false capacity.

2. Road requirements

The height and spacing of solar streetlights need to be determined according to road requirements. First, you need to know the width of the road used by the solar street light, to choose to use a single-arm or double-arm solar street light; secondly, look at the interval between the solar street lights, and choose the brightness of the lamp power; finally, the height of the solar street light pole should be considered to determine the size of the lamp power and brightness.

3. Warranty time

Generally, the warranty period for solar streetlights is 1-5 years. The longer the warranty period, the more guaranteed the quality of the street light, but the price will also be relatively higher.

4. Brand

When purchasing solar streetlights, you should pay attention to the strength and reputation of the brand manufacturer. This can be learned through online inquiries. You can consult various brands to understand the specific strength of the manufacturer and compare prices to choose products with good quality and high-cost performance.

5. Advantages and Disadvantages of Solar Street Lights

Advantages:

1. Easy installation: When installing solar streetlights, there is no need to set up complex auxiliary lines. Just make a cement base, make a battery pit, and fix it with galvanized bolts. It does not require a lot of manpower, material resources, and financial resources. The installation is simple, and there is no need to string wires or “open the belly” to dig the ground for construction, and there is no worry about power outages.

2. Low investment: Solar street lights are a one-time investment and have long-term benefits. Due to the simple lines, there is no maintenance cost and no expensive electricity bills. The cost is recovered in 6-7 years, and more than 100,000-200,000 US dollars in electricity and maintenance costs are saved in 3-4 years. It can save the high electricity bills of city circuit lights, complex lines, and long-term uninterrupted line maintenance. Especially in the case of unstable voltage, it is inevitable that sodium lamps are easy to break, and as the years go by, the line ages, and the maintenance costs increase year by year.

3. Good safety performance: Solar street lights use 12-24V low voltage, stable voltage, reliable operation, and no safety hazards. They are ideal products for ecological communities and road administration departments. There are no accidents such as electric shock and fire. The safety hazards of municipal street lights are great. People’s living environment is constantly changing. Road reconstruction, landscape construction, abnormal power supply, cross-construction of water and gas pipelines, etc. bring many hidden dangers.

4. Energy saving and environmental protection: Solar photovoltaic conversion provides electricity, which is inexhaustible. No pollution, no noise, no radiation. Solar streetlights can add new selling points to the development and promotion of noble ecological communities; they can sustainably reduce property management costs and reduce the public share of owners. In summary, the inherent characteristics of solar lighting, such as safety, no hidden dangers, energy saving, no consumption, green environmental protection, easy installation, automatic control, and maintenance-free, will directly bring obvious advantages to the sales of real estate and the construction of municipal projects.

5. Long life: The life of solar lamps is much longer than that of ordinary electric lamps. For example, the main component of solar lamps, the solar cell module, has a service life of 25 years; the average life of low-pressure sodium lamps is 18,000 hours; the average life of low-voltage high-efficiency tri-color energy-saving lamps is 6,000 hours; the average life of ultra-bright LEDs is more than 50,000 hours; the life of solar-specific batteries is 2-5 years for batteries below 38AH; 3-7 years for batteries between 38 and 150AH.

The product has high technological content, and the control system and accessories are all international brands, intelligently designed, and reliable in quality. According to the regulations of the local Price Bureau of conventional communities “a one-time fee of 1$/㎡ for community street lamp maintenance is charged based on the pure residential building area”, the initial investment of ordinary lamps is much higher than that of solar lamps. In short, the comprehensive comparison shows that the investment-saving feature of solar lamps is quite obvious.

Disadvantages:

1. High cost, the initial investment of solar street lamps is relatively large, and the total cost of a solar street lamp is 3.4 times that of conventional street lamps with the same power.

2. Low energy conversion efficiency. After the actual installation of solar photovoltaic cells, the conversion efficiency may be about 15%~19% due to the obstruction of surrounding buildings.

3. Affected by climatic conditions. Since it relies on solar energy to provide energy, the local geographical climate and weather conditions directly affect the use of street lights. Long rainy days will affect the lighting, resulting in illumination and brightness failing to meet national standards or even no lighting.

4. Low service life and cost performance of components. The price of batteries and controllers is high, and the batteries are not durable enough and must be replaced regularly. The service life of the controller is generally only about 3 years.

5. Low reliability. Due to the great influence of external factors such as climate, the reliability is reduced.
