A solar street light proposal is not a brochure. It’s a tender-ready engineering document that helps you get approved, install smoothly, and pass acceptance without rework.
If you can’t prove uniformity between poles, rainy-season autonomy, and a clean handover checklist, your project is exposed—no matter how “bright” the demo looks.
Answer these 3 questions in 30 seconds (or risk rejection):
1) Will the road be bright between poles (uniformity)?
2) Will it run through the rainy season (autonomy nights + dimming profile)?
3) Can your EPC team handover smoothly (acceptance checklist + documents)?

What Makes a Proposal “Tender-Ready” (Not Just a Template)
Many suppliers sell “watts.”
In tenders, you’re judged on light on the ground and how safely the project can be accepted.
A tender-ready proposal reduces uncertainty with measurable outcomes:
- Illuminance & uniformity (not “looks bright under the pole”)
- Rainy-season autonomy (not “battery capacity sounds big”)
- Acceptance & handover documents (not “trust us”)
Include this line in your proposal for faster approvals:
“Lighting design deliverables are included: IES files + simulation summary based on road width, pole height, and pole spacing.”

10) Why Contractors Trust Us (We’ve Got Your Back)
Many suppliers sell watts. We sell light on the ground.
We design with IES and simulation first because the expensive part of a project is not the lamp—it’s rework and rejected handover.
If you share your layout and inputs, our team will help you avoid the common failure points:
- dark zones between poles
- wrong optics selection
- undersized battery for rainy season
- mismatched pole foundation details
11) Warranty, Maintenance & Spares Strategy
- System warranty: [__] years
- Battery warranty: [__] years (define conditions)
- Recommended spares: 2–3% critical parts
- Maintenance: quarterly visual checks; annual fastener inspection for dusty/coastal sites
12) Risk & Mitigation (Optional but Strong)
| Risk | Impact | Mitigation |
|---|---|---|
| Prolonged rainy season | Dimming / shorter runtime | Increase autonomy + optimize dimming profile |
| Coastal corrosion | Pole/fastener deterioration | Hot-dip galvanizing + suitable coating |
| Theft/vandalism | Asset loss | Anti-theft screws, elevated battery design |
| Wrong spacing/pole height | Dark zones between poles | Simulation-based layout recommendation |
FAQ (People Also Ask)
How many solar street lights do I need per kilometer?
It depends on pole spacing. Quick reference:
- 25m spacing → about 40 poles/km
- 30m spacing → about 33 poles/km
Final quantity should follow layout and lighting simulation.
How do I size the battery for rainy season?
Battery sizing should follow load (W) × hours/night × autonomy nights, plus system losses and temperature factors. Always define a dimming profile in the proposal instead of listing battery Ah only.
How much does a solar street light cost?
Prices vary based on autonomy requirements (battery size), lighting performance targets (lux/uniformity), pole height, and corrosion environment. A “3-night autonomy” system costs more than a “1-night” system—but it can save you from blackouts and project rejection.
