2025 solar street lamp project implementation plan
1. Solar street lamp project objectives and scope
Solar street lamp core objectives
Improve the quality of lighting in public areas at night, ensure traffic safety and the convenience of residents' lives, reduce traditional energy dependence, and promote green and low-carbon development.
Achieve energy conservation and emission reduction : reduce carbon emissions through solar power supply, reduce electricity costs and maintenance costs (expected maintenance costs will be reduced by more than 40%).
Coverage
Key implementation areas: rural main roads, public squares, parks and old urban roads .
Expansion scenario: areas requiring improved night lighting such as industrial parks and surrounding schools .
2. Solar street lamp technical parameters and equipment selection
Street lamp specifications
The solar street lamp with pole height 6.5 meters and 40W LED light source is selected to meet the needs of rural and urban roads .
Equipped with polycrystalline silicon solar panel (conversion efficiency ≥18%), lithium battery energy storage system (battery life ≥3 rainy days).
Intelligent function extension
Support light control + time control dual mode , automatically adjust the lighting time according to the ambient brightness .
Old street lamp transformation plan: retain the original light pole, install split solar modules (including panels, energy storage modules), reduce the transformation cost.
3. Solar street lamp implementation steps and division of labor
The preliminary preparation
Site investigation : Determine the location layout of street lights, avoid trees and ensure uniform illumination (25-30 meters spacing is recommended).
Personnel training : Organize the construction team to learn installation norms and safe operations (including aerial work, electrical wiring, etc.).
Construction process
Foundation construction : anchor bolts are embedded and concrete foundation is poured (depth ≥ 1.2m).
Module installation : The solar panel should be tilted to the south (the Angle should be adjusted according to the latitude), and the height and inclination of the luminaire should meet the road lighting standards.
System debugging : test charge and discharge performance and lighting brightness, optimize controller parameters.
Acceptance and handover
Site acceptance shall be carried out jointly with designer, supervisor and beneficiary village representative to check quantity, illumination and installation process .
Sign 5-year warranty agreement and specify maintenance responsibilities (such as battery replacement, panel cleaning, etc.) .
4. Solar street lamp answers to frequently asked questions
Insufficient battery life on rainy days : Configure redundant battery capacity and add energy storage module .
Equipment failure : establish a 24-hour response mechanism, relying on local service providers quick maintenance.
5. Solar street lamp sustainable operation and maintenance
Regular inspection (once every quarter) to clean solar panel dust and detect the aging condition of the circuit .
Continuously optimize the lighting scheme through villagers' satisfaction survey (target ≥90%).
Implementation cycle : Start in March 2025 and complete before the end of November 2025 (refer to Daye City project node) .
Expected benefits : Improving night travel conditions for 100,000 + residents and reducing carbon emissions by about 500 tons per year .
