The use of solar street lights as an Eco-friendly and economical lighting option for public spaces has increased. These lights are not only economical and safe, but also Eco-friendly. Thus, in an effort to save running costs and enhance night-time traffic safety, an increasing number of governments have chosen to install solar streetlights on public roads and in outdoor parking lots adjacent to government buildings.
Steps to Finish Government Solar Street Light Project
Step 1: Solar Street Light Project Background Research
Describe the general conditions of the project region, taking into account its location, climate, and other factors. Identify the potential issues with the current street lighting systems, such as energy usage, upkeep costs, etc.
Step 2: Solar Street Light Requirements Analysis
Enumerate the project’s primary needs, such as supplying sufficient lighting, conserving energy, protecting the environment, cutting maintenance expenses, etc.
Step 3: Solar Street Light Design Plan
The use of solar street lighting is suggested as a solution based on variables like temperature, sunlight coefficient, road width, duration of rainy season, etc. Introducing the basic idea behind how solar street lights operate: light is captured by solar panels and stored in batteries to provide night-time illumination. An assessment of the installation environment
the primary source of energy for photovoltaic street lights is sunshine, hence an environmental study must be done prior to installation and design.
1. Sunshine time: greater than 2000H
2. Ambient temperature: minus 20℃–65℃
3. Surrounding environment:
a. Verify whether any structures, trees, etc. are obstructing the road in the installation area on both sides, primarily the east and west or south sides. Measure the height and distance of any trees or structures that are obstructing the illumination from the installation location, and compute Ascertain if it has an impact on the solar cell module’s lighting. Generally speaking, solar lighting must be able to guarantee that there are no obstructions that might affect the lighting between the hours of 9:00 am and 3:00 pm.
b. Examine the area above the solar light installation position for any cables, wires, or other structures that can interfere with the installation of the lamps (Note: Installing solar lamps beneath high-voltage lines is absolutely forbidden);
c. Recognize the presence of any pipes, cables, optical cables, or other facilities that could have an impact on the subterranean construction of the solar street light foundation and battery compartment, as well as any construction-prohibition signage. Steer clear of the facilities listed above when installing. If avoiding them is not feasible, kindly get in touch with the appropriate departments, negotiate, and come to an agreement before starting construction.
d. Avoid installation in low-lying, soft soil or areas prone to water accumulation;
e. Take on-site photos of the installation area;
f. Measure the road section’s width, length, height, and other features. Also, note the direction of the road and give the plan designer any relevant images or data.
Step 4: Solar Street light Technical parameters
List the key technical parameters of the selected solar street lights, including solar panel efficiency, battery capacity, LED lighting effect, etc.
1. Light pole: 6000mm customized tapered street light pole; dimensions for look, color, and size are shown in the design. Both the interior and outside are sprayed with plastic and hot-dip galvanized. The surface has been coated to prevent corrosion and rust. It resists wind, is flat and smooth, and won’t peel for ten years. Strength: 100 miles per hour.
2. Working hours: twelve hours a night, seven days a week with rain.
3. The body of the street lamp is 545 mm long. Kindly consult the image for the style of the light head.
4. The solar panel is positioned on the solar bracket, the battery module is positioned on the solar bracket and beneath the solar panel, and the controller is inserted within the battery module. It is simple to install and portable.
5. Using expansion screws, the solar bracket is secured to the street light pole.
6. The polycrystalline silicon solar panels have a 200W total rated output power, a ≥15-year service life, and a 5-year warranty. They also have a ≥18.5% conversion efficiency and a ≤3% power deviation rate. Additionally, they can withstand 2200Pa of snow pressure and 3200Pa of wind pressure.
7. Use a lithium iron phosphate battery, which has a ≥5-year service life, a 5-year guarantee, a capacity variation rate of ≤5%, and a temperature range of -20°C to 65°C.
8. LED light source specifications: 36W rated power, ≥135lm/w lamp efficiency, 50000h service life, ≤3% average yearly attenuation rate, and 5 years guarantee. Using imported high-power LED integrated chips.
9. Controller: (1) Lifespan ≥5 years, free guarantee for 1 year; (2) Specifications: 24V, 10A, integrated light control and time control; The product includes the following features: low voltage energy saving protection, charging voltage protection, instantaneous high current protection during load startup, safety lightning protection, load short circuit protection, reverse polarity protection, load overcurrent protection, and reverse discharge protection. (4) Static average power consumption ≥0.05W; (5) Laboratory performance test for high and low temperature resistance, -25℃～70℃, which can ensure normal long-term operation at at least -10℃⌞60℃.
10. LED solar lights Wind resistance: more than 100 km/h; IP65 protection level.
Step 5: Solar street light government project Design details
A detailed description of the components and installation methods of solar street lights, including the layout of solar panels, the installation height of lamps, etc.
1. According to the width of the road and lighting requirements, choose the lighting installation method:
a. One-sided arrangement
b. Bilateral staggered arrangement
c. Bilateral symmetrical arrangement;
Height of the solar street light pole
The LED bulbs’ illuminating range is directly impacted by the height of the solar-powered street light. The Pythagorean Theorem states that the illumination range increases with light pole height.
For our palm tree foldable all-in-one solar street light as an example:
22 meters between poles, a 6 meter pole, and a 60 watt solar street light
8–10 m poles, 30 m between poles, and 100 w solar street light; 9–12 m poles, 35 m between poles, and 120 w solar street light.
Parks and scenic areas are typically good places to put solar-powered street lights that are around 7 meters in length. Since there is little foot and vehicle traffic on rural roads at night, interactive lighting is often deployed one way, with a 20–25 meter installation distance. A portion of the lights will be impacted if it is less than 20 meters. To prevent lighting blind spots, an additional street light ought to be erected at the corner.
Step 6: Economic Analysis
Examine the financial advantages of employing solar-powered street lighting options, such as reduced energy use, lower consumption, lower maintenance costs, etc. Examine the total cost and yield of solar street lighting vs conventional electric street lights.
Step 7: Sustainability and environmental protection
Reduce carbon emissions, lessen reliance on energy sources, and highlight the benefits of solar street light systems for sustainability and environmental protection.
Step 8: Risks and Challenges
Enumerate potential dangers and difficulties, including the effect of erratic weather on energy harvesting, equipment upkeep, and other problems.
Step 9: Future Outlook
Anticipating the potential for solar street light growth in the future, along with the potential advancements and modifications that come with technical advancements.
