Solar energy is an inexhaustible, clean, pollution-free, and renewable green and environmentally friendly energy source. Utilizing solar power generation has unparalleled advantages over conventional energy sources such as cleanliness, high safety, relative universality and adequacy of energy, long lifespan, and maintenance free. Photovoltaic energy is considered the most important new energy source in the 21st century. Solar street lights do not require cable laying, AC power supply, and do not incur electricity bills; Adopting DC power supply and control; It has the advantages of good stability, long service life, high luminous efficiency, easy installation and maintenance, high safety performance, energy conservation and environmental protection, and economic practicality. It can be widely used in urban main and secondary roads, residential areas, factories, tourist attractions, parking lots, and other places. Product component light pole structure.
Explanation of the working principle of solar street lights: During the day, under the control of an intelligent controller, solar street lights are illuminated by sunlight, absorbed by solar panels, and converted into electrical energy. During the day, solar cell components charge the battery pack, and at night, the battery pack provides power to the LED light source, achieving lighting functions. The DC controller can ensure that the battery pack is not damaged due to overcharging or discharging, and has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection
The solar street light system can ensure normal operation in cloudy and rainy weather for more than 15 days! Its system consists of LED light sources (including drivers), solar panels, batteries (including battery insulation boxes), solar street light controllers, street light poles (including foundations), and auxiliary materials and wires.
Solar cell modules generally use monocrystalline silicon or polycrystalline silicon solar cell modules; LED lamp holders generally use high-power LED light sources; The controller is generally placed inside the lamp pole and has functions such as light control, time control, overcharging and discharging protection, and reverse connection protection. More advanced controllers have functions such as adjusting the lighting time throughout the year, half power function, and intelligent charging and discharging function; Batteries are generally placed underground or equipped with specialized battery insulation boxes, which can be valve regulated lead-acid batteries, colloidal batteries, iron aluminum batteries, or lithium batteries. The solar lighting fixtures are fully automatic and do not require trenching and wiring, but the lamp poles need to be installed on embedded parts (concrete bases)
LED light source
1. High luminous efficiency, low power consumption, long service life, and low working temperature.
2. Strong safety and reliability.
3. Fast reaction speed, small unit volume, green and environmentally friendly.
At the same brightness, the power consumption is one tenth of that of incandescent lamps and one-third of that of fluorescent lamps, but the lifespan is 50 times that of incandescent lamps and 20 times that of fluorescent lamps. It is the fourth generation lighting product after incandescent lamps, fluorescent lamps, and gas discharge lamps.
The emergence of a single high-power ultra bright LED makes it possible for the LED application field to cross into the high-efficiency lighting source market, and will be one of the greatest inventions of humanity after Edison's invention of incandescent lamps. [3]
Battery module bracket
1) Inclination design
In order to receive as much solar radiation as possible within a year, we need to choose an optimal tilt angle for the solar cell module.
The discussion on the optimal inclination angle of solar cell modules is determined according to different regions when used in different regions.
2) Wind resistant design
In solar street lighting systems, a structural issue that requires great attention is wind resistance design. The wind resistance design is mainly divided into two parts: one is the wind resistance design of the battery module bracket, and the other is the wind resistance design of the lamp pole. Let's analyze the above two parts separately.
Wind resistance design of solar cell module bracket
According to the technical parameter data of the battery module manufacturer, the upwind pressure that the solar cell module can withstand is 2700Pa. If the wind resistance coefficient is selected as 27m/s (equivalent to a Category 10 typhoon), according to non viscous fluid mechanics, the wind pressure borne by the battery module is only 365Pa. So, the component itself can fully withstand a wind speed of 27m/s without damage. So, the key consideration in the design is the connection between the battery module bracket and the lamp pole.
In the design of this street light system, the connection between the battery module bracket and the lamp pole is fixed and connected using a bolt pole.
controller
The main function of the solar charging and discharging controller is to protect the battery. The basic functions must include overcharge protection, over discharge protection, light control, time control, anti reverse connection, charging trickle protection, undervoltage protection, waterproof protection, etc. [1]
1) Device selection
In terms of device selection, there are currently both single-chip microcontrollers and comparators. There are many solutions, each with its own characteristics and advantages. Corresponding solutions should be selected based on the needs and characteristics of the customer group, and will not be detailed here.
2) Surface treatment
This series of products adopts new electrostatic coating technology, mainly FP professional building material coatings, which can meet customers' requirements for consistent surface color and environmental coordination. At the same time, the products have high self-cleaning performance, strong corrosion resistance, aging resistance, and are suitable for any climate environment. The processing technology is designed to be coated on the basis of hot dip galvanizing, greatly improving the product performance and meeting the strictest requirements of AAMA2605.2005. Other indicators have met or exceeded the relevant requirements of GB.
3) Charging Trickle Protection
When charging the battery with Yijia solar panel, if the battery continues to charge at high voltage after reaching its peak voltage, it may cause water loss or loss of control of the battery; If the battery cannot saturate when charging is stopped. This controller immediately reduces voltage by 1V after charging to the peak voltage, and then enters a trickle charging state, ensuring that the battery can be stable in a full state while avoiding water loss or loss of control. Similar to cycling charging the battery, it not only efficiently protects the battery, but also increases the charging frequency and service life of the battery.
1. Easy installation: When installing solar street lights, there is no need to install complex circuits, just make a cement base and a battery pit, and fix them with galvanized bolts. There is no need to consume a large amount of manpower, material resources, or financial resources, and the installation is simple. There is no need for stringing or "digging through the ground" construction, and there is no concern about power outages and power restrictions..
2. Low investment: Solar street lamps can benefit from a one-time investment and long-term benefits. Due to their simple circuit, they do not incur maintenance costs and expensive electricity bills. 6-7 years to recover costs, 3-4 years to save over 1 million yuan in electricity and maintenance costs. It can save the high electricity cost of city circuit lights, complex wiring, and the need for long-term uninterrupted maintenance of the wiring. In the case of unstable voltage, it is inevitable that sodium lamps are prone to damage, and with the extension of service life, the aging of the circuit and maintenance costs increase year by year.
3. Good safety performance: Due to the use of 12-24V low-voltage, stable voltage, reliable operation, and no safety hazards, solar street lamps are ideal products for ecological communities and road administration departments. There are no accidents such as electric shock or fire. The safety hazards of city circuit lights are significant, and people's living environment is constantly changing. Road renovation, landscape engineering construction, abnormal power supply, and cross construction of water and gas pipelines have brought many hidden dangers .
4. Energy conservation and environmental protection: Provide electricity through solar photovoltaic conversion, which is inexhaustible and inexhaustible. No pollution, no noise, no radiation. Solar street lights can add new selling points for the development and promotion of noble ecological communities; Sustainable reduction of property management costs and reduction of public shared expenses among property owners. In summary, the inherent characteristics of solar lighting, such as safety and no hidden dangers, energy conservation and no consumption, green and environmental protection, easy installation, and automatic control and maintenance free, will directly bring obvious and exploitable advantages to the sales of real estate and the construction of municipal engineering.
5. Long lifespan: The lifespan of solar powered lighting fixtures is much higher than that of ordinary electric lighting fixtures, such as the main component of solar powered lighting fixtures - the solar cell module, which has a lifespan of 25 years; The average lifespan of low-pressure sodium lamps is 18000 hours; The average lifespan of low-voltage and high-efficiency three primary color energy-saving lamps is 6000 hours; The average lifespan of ultra bright LED is more than 50000 hours; The service life of solar dedicated batteries is 2-5 years below 38AH; 3-7 years from 38-150AH. The product has high technological content, and the control system and accessories are all international brands with intelligent design and reliable quality. According to the regulations of the local price bureau, which stipulate that street light maintenance fees of 6 yuan/square meter should be charged at once based on the pure residential building area in conventional residential areas, the initial investment of ordinary lighting fixtures is much higher than that of solar lighting fixtures. In summary, the characteristics of saving investment in solar lighting fixtures are quite obvious from a comprehensive comparison.
In the solar power supply system, the performance of the battery directly affects the comprehensive cost, operation and service life of the system. In this scheme, the latest energy storage gel battery jointly developed by the company and the Institute of Metals, Chinese Academy of Sciences is selected. Compared with ordinary lead-acid batteries, it has the following outstanding features in design and manufacturing process:
The service life is extremely long, with a normal service life of five to ten years.
Adopting suitable positive and negative electrode alloy formula and active material ratio, making the battery more suitable for the use characteristics of cyclic charging and discharging of energy storage batteries
Lamp installation
1. Fix the components of each part: fix the solar panel to the solar panel bracket, fix the lamp head to the cantilever arm, and then fix the bracket and cantilever arm to the main pole, and thread the connecting wire to the control box (battery box).
Before lifting the lamp pole, check whether the fasteners in each part are secure, whether the lamp head is installed correctly, and whether the light source is working properly. Then, check whether the simple debugging system works normally; Release the solar panel connection wire on the controller, and the light source will work.
When lifting the main light pole, pay attention to safety precautions; The screws are absolutely tightened. If there is a deviation in the sunrise angle of the component, it is necessary to adjust its sunrise direction to fully face due south at the upper end.
4. Place the battery into the battery box and connect the connecting wire to the controller according to technical requirements; Connect the battery first, then the load, and then the solar panel; When conducting wiring operations, it is important to ensure that all wiring and the terminals marked on the controller are not connected incorrectly, and that the positive and negative polarities do not collide or be connected in reverse; Otherwise, the controller will be damaged.
5. Whether the debugging system is working properly; Release the solar panel connection wire on the controller, and the light will be on; Connect the solar panel connection wire and turn off the light; At the same time, carefully observe the changes of each indicator light on the controller; Only when everything is normal can the control box be sealed.
In terms of working principle, solar street lights use solar energy as the light source, and during the day, the solar panel will charge the battery. At night, when lighting is needed, the battery will start supplying power to the light source. It does not require the installation of complex and expensive power supply lines in use, making it possible to install it in any environment on any site. Its battery uses natural light and can be recycled without external power supply. The source is green and environmentally friendly. When the sunlight is insufficient to a certain extent, the solar street light can automatically adjust the switch, truly achieving unmanned and all-weather operation.
Compared to traditional high-voltage incandescent street lamps, solar street lamps have significant differences in product characteristics, material structure, and power supply lines. Solar street lights are a type of traffic lighting that our country uses solar energy as a new energy source for external power supply of street lights. In urban life, street lights play a very important role and are the eyes of our travel and nightlife.
In terms of product characteristics, solar street lamps use solar energy as the light source. During the day, it can use solar circuit boards to charge the batteries inside the streetlights. At night, the batteries can supply power to the lights, fully meeting the lighting needs. The solar power source used in solar street lights is green and environmentally friendly, and can be seen everywhere in nature. This saves materials required for laying power lines, saves a lot of manpower and resources, and improves construction efficiency. In addition, solar street lights are environmentally friendly, energy-saving, and have a long service life, stable product structure, and have very good social and economic benefits.
