Project
Solar LED Streetlight Retrofit in Punjab, Pakistan
Project Background / Purpose
With the increasing demand for energy-saving and clean energy, solar LED street light retrofitting has become a mainstream solution for municipal and enterprise road lighting.
This article takes the project in Pakistan as an example to introduce how to retrofit an 8.5-meter lamp post with solar-powered LED lighting, ensuring long-lasting and high-brightness performance for nighttime road illumination.
- Location: Punjab Province
- Application: Road / Street lighting, for nighttime road safety lighting
1. Project Site
Latitude: 70.02997, Longitude: 28.26150
Longitude: 70.02997, Latitude: 28.26150
Address: Punjab Province
2. Client’s Requirement
- Install the solar street light on 8.5meters lamp post
- Lighting effect: 15-20lux
- Lighting Hours: 8-10hrs, still light on in 12hrs
3. Proposed Solution
1)Product Solution
① Light head with built-in Lithium battery/Smart controller
（The lightweight body has a big battery box, so it is easy for your replacement）
② Monocrystalline high-efficiency solar panel
2)Actual product testing
① Light head with built-in Lithium battery/Smart controller
② Mono crystalline high efficiency solar panel
4. How to replace?
1)For reference
① Method 1: Use one adaptor and solar support bracket
② Method 2: Use one connector and solar support bracket
2) Details for Method 1
Our Proposal:
We will send the solar light set with the method 1 adaptor and solar support bracket.
In the meantime, I will provide you with the Method 2 connector for your reference.
Project Details
| Item | Details |
|---|---|
| Existing System | Existing 8.5‑meter lamp posts, using traditional light sources — high energy consumption, insufficient illumination |
| Upgrade Goals | Increase nighttime illumination to 15‑20 Lux, operation for 8‑10 hours, visible light for up to 12 hours; reduce energy consumption and maintenance cost |
| Product Model / Configuration | Solar LED light head with built‑in lithium battery + smart controller; mono‑crystalline high‑efficiency solar panels; large battery compartment for easy maintenance |
| Installation Scheme | Method 1: Adaptor + adjustable solar panel bracket mounted at the end of the arm; Method 2: Connector + bracket mounted middle of arm; Recommendation: Method 1 as main solution, Method 2 as alternative |
| Monitoring / Control Method | Photocell for automatic on/off; motion sensing control if needed |
| Energy Efficiency & Savings Rate | In tests at ~8m height illumination reached 19‑20 Lux; energy consumption reduced by about 50‑70% vs original system |
| Customer Feedback | Significant improvement in lighting quality; improved nighttime safety; easy maintenance |
