The school solar street light project is an environmentally friendly and energy-saving lighting solution, which is particularly suitable for the campus environment. The following are the detailed planning and implementation points of the project:

1. Project background and goals

Background: Respond to the green campus initiative, reduce carbon emissions, and reduce electricity bills.

Goal: Provide stable lighting for campus roads, squares, parking lots and other areas to improve nighttime safety.

2. System composition

Solar panels: Convert light energy into electrical energy. It is recommended to choose monocrystalline silicon (high efficiency and long life).

Batery: Stores electrical energy and can last for 3-5 days on rainy days (such as gel batteries or lithium batteries).

ED street lights: Energy-saving and efficient, color temperature recommended 4000K-5000K (warm white or natural white).

Controller: Intelligently adjust charging and discharging, with overcharge/overdischarge protection.

Light pole: Height 4-6 meters (depending on the width of the road), made of hot-dip galvanized steel.

3. Design points

Lighting requirements: adjust the brightness according to the regional function, such as 15-20 lux on the main road and 5-10 lux on the trail.

Installation spacing: 20-30 meters/lamp on the main road and 30-40 meters/lamp on the auxiliary road.

Wind-resistant design: the lamp poles must meet the local maximum wind force requirements (such as resistance to level 12 wind).

4. Advantage analysis

Zero electricity cost: completely dependent on solar energy, no grid dependence.

Low maintenance: The system life is about 8-10 years, and only regular cleaning of the solar panels is required.

Safety: No high-voltage lines to avoid the risk of electric shock.

5. Implementation steps

Survey: Measure the sunlight conditions and shadow shielding in the installation area.

Selection: Match components according to power requirements (such as 50W LED with 150W solar panel + 100Ah battery).

Construction: foundation pouring (concrete grade C25), wiring (waterproof junction box), and debugging.

Acceptance: continuous rain and cloudy test, brightness test.

6. Budget reference

The cost of a single set is about ￥2000-4000 (including installation), depending on the configuration.

Compared with traditional street lights, the investment can be recovered through electricity bill savings in 3-5 years.

7. Precautions

Avoid trees or buildings blocking the panels.

Low-temperature resistant batteries should be selected in northern regions (such as lithium batteries that still work at -20℃).

A human body sensing module can be installed to automatically turn on the lights when people come.

8. Extended functions

Smart monitoring: integrated WiFi module, remote control of brightness/switch.

Promotional screen: electronic screen installed on the lamp pole to display campus information.

Through reasonable design, solar street lights can become a landmark facility for sustainable development on campus, while cultivating students' environmental awareness. It is recommended to give priority to pilot projects around dormitory areas and libraries, and then gradually promote them to the whole school.
