Solar Street Lights Government Project Proposal

Solar Street Lights Government Project Proposal

Solar streetlights have grown in popularity as a sustainable and energy-efficient lighting solution for public areas. Along with being environmentally friendly, these lights are safe and cost-effective. So more and more governments decided to adopt solar streetlights on government roads and outdoor car parks of government buildings to improve the safety of the traveling environment at night and reduce operating costs.

Steps to Finish Government Solar Street Light Project

Step 1: Solar Street Light Project Background Research

Introduce the basic situation of the project area, including geographical location, climate characteristics, etc.

Point out the problems that existing street lighting systems may face, such as energy consumption, maintenance costs, etc.

Step 2: Solar Street Light Requirements Analysis

List the main requirements of the project, including providing adequate lighting, energy conservation, and environmental protection, reducing maintenance costs, etc.

Step 3: Solar Street Light Design Plan

Based on factors such as sunshine coefficient, temperature, road width, length of rainy season, etc., the solution of using solar street lights is proposed.

Introducing the working principle of solar street lights: energy is collected through solar panels and stored in batteries for night lighting.

Evaluation of the installation situation

Photovoltaic street lights mainly rely on sunlight to provide working energy and environmental assessment must be carried out before installation and design.

1. Sunshine time: greater than 2000H

2. Ambient temperature: minus 20℃–65℃

3. Surrounding environment:

a. Check whether there are trees, buildings, etc. blocking both sides of the road in the installation section (mainly the south side or the east and west sides). If trees or buildings are blocking the lighting, measure its height and distance from the installation site, and calculate Determine whether it affects the lighting of the solar cell module; the general requirement for solar lighting is that the solar lighting can at least ensure that no obstruction affects the lighting between 9:00 am and 3:00 pm.

b. Observe whether there are cables, wires, or other facilities above the installation location of the solar lamps that may affect the installation of the lamps (Note: It is strictly prohibited to install solar lamps under high-voltage lines);

c. Understand whether there are cables, optical cables, pipelines, or other facilities that may affect the construction of the solar street light foundation and battery compartment underground and whether there are any signs prohibiting construction, etc. When installing, try to avoid the above facilities. If it is impossible to avoid them, please contact the relevant departments and negotiate and agree before proceeding with 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 width, length, height, and distance of obstructions and other parameters of the road section, record the road direction, and provide photos and other data to the scheme designer for reference.

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 special tapered street light pole; please see the drawing for appearance size and color requirements. It is made of hot-dip galvanizing/plastic spraying inside and outside.

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 height of the solar power street light directly affects the illumination range of the LED lamps. The higher the light pole, the wider the illumination range according to the Pythagorean theorem.

For our palm tree foldable all-in-one solar street light as an example:

6m pole, pole to pole distance is 22m, with 60W  solar street light
8-10m pole, pole to pole distance is 30m, with 100W solar street light
9m-12m pole, pole to pole distance 35m, with 120W solar street light

Scenic spots and parks are generally suitable for installing solar power street lights of about 7 meters, At night, the traffic of pedestrians and vehicles on rural roads is not large, so it is generally installed by one-sided interactive lighting, and the installation distance is about 20-25 meters. If it is less than 20 meters, part of the lighting will be affected. In addition, one more street light should be installed at the corner to avoid lighting blind spots.

Step 6: Economic Analysis

Analyze the economic benefits of using solar street light solutions, including energy saving, consumption reduction, maintenance cost savings, etc.

Compare the overall investment and return of traditional electric street lights and solar street lights.

Step 7: Sustainability and environmental protection

Emphasize the sustainability and environmental protection advantages of solar street light solutions, reduce carbon emissions, and reduce energy dependence.

Step 8: Risks and Challenges

List possible risks and challenges, such as the impact of unstable weather conditions on energy collection, equipment maintenance, and other issues.

Step 9: Future Outlook

Looking forward to the future development prospects of solar street lights, combined with the improvements and innovations that may be brought about by technological progress.
