What environments are solar street lights suitable for?
Nowadays, solar photovoltaic has a wide range of applications, and various solar products are emerging one after another. Among them, solar street lights are a relatively common facility that has entered our sight, and traditional street lights are slowly disappearing from our sight. So, what environments are solar street lights suitable for? Ming Feng lighting Co., LTD solar street lamp manufacturer will tell you about it.
1. Solar street lights are suitable for areas with a wide altitude range. Solar street lights have certain requirements for installation altitude, but with technological improvements, the range of altitude requirements is wider, as long as the altitude is below 5000 meters, they can be installed and used. It is generally not recommended to use solar street lights in areas above 5000 meters above sea level, but there is basically no requirement for elevations below 5000 meters, which can be applied to users in ordinary areas.
2. Solar street lamps are suitable for areas with a wide range of air temperature differences. Secondly, solar streetlights also have certain requirements for air temperature, but with technological improvements, solar streetlights can withstand a larger temperature range, usually used below 70 degrees Celsius and above -50 degrees Celsius. Users can use it with confidence in general living environments.
3. Solar street lamps are suitable for areas with a wide humidity range. Solar street lamps also have certain requirements for humidity. With the advancement of technology, solar street lamps have lower requirements for humidity environments and stronger load-bearing capacity. Generally, as long as the humidity is below 80%, it can be installed and used.
The above is the applicable environment for solar street lights. If you want to learn more, please feel free to contact us directly.
The following is the basic knowledge about solar street lights, to share with everyone.
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). [2]
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.
Wind resistance design of street lamp poles
The parameters of street lights are as follows:
Battery panel inclination angle A=16o, lamp pole height=5m
Design and select the width of the weld seam at the bottom of the lamp pole δ = 4mm light pole bottom outer diameter=168mm
The surface where the weld seam is located is the damaged surface of the lamp 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. [4]
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
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 [1].
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 [3].
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 formulas and active material ratios makes the battery more suitable for the use characteristics of cyclic charging and discharging of energy storage batteries.
The design of colloidal electrolyte effectively suppresses the rust removal of active substances and the sulfation phenomenon of the electrode plate, thereby delaying the performance degradation of the battery during use. Greatly improves the deep charge discharge cycle life of the battery. Select the fourth generation lighting product LED light source
