|---|---|---|
| Energy Bills | $50–$200/year | $0 |
| Trenching & Wiring | $1,000+ per 100m | $0 |
| Maintenance (5 years) | Moderate–High | Low |
| Replacement Battery | N/A | $30–$70 |
2. Environmental and Social Benefits
- Zero emissions: Reduces carbon footprint
- Off-grid use: Ideal for remote or rural areas
- Low light pollution: Directed LED lighting
- Improved safety: Crime and accident reduction
3. Maintenance and Reliability
Modern solar lights are built to last:
- Battery life: 3–8 years
- LED lifespan: 50,000+ hours
- Panel lifespan: 20–25 years
4. ROI in Public and Commercial Projects
Most projects see a payback within 2–4 years.
Examples:
- Municipalities: Save over $100,000/year by switching 500 lights
- Developers: Avoid wiring/infrastructure costs
- Tourism zones: Energy independence with green branding
5. Solar vs. Traditional Street Lights
| Feature | Solar Lights | Traditional Lights |
|---|---|---|
| Energy Source | Sunlight | Grid electricity |
| Operating Cost | Low to none | Ongoing bills |
| Installation | Simple, wireless | Wiring + trenching |
| Maintenance | Low | Moderate |
| Eco Impact | Positive | Carbon emissions |
| Lifespan | 10–25 years | 5–10 years |
