Project Background

This reference deployment in Sri Lanka uses 532 sets of 80W all-in-one solar street lights on 7m poles for road and public-area sections. The EPC workflow prioritised documented layout assumptions (pole height, spacing intent, optics), clear deliverables (IES/LDT on request, BOQ mapping notes), and practical acceptance checks to reduce installation risk and rework.
Technical Configuration (Typical Range)
✓
Roadway optics with IES photometric files available for layout verification (on request)
✓
Typical mounting: 7 m poles with 80 W luminaires, spacing set by road width and maintained lux targets
✓
All-in-one architecture: integrated PV + LiFePO4 sized by autonomy and local conditions (scope-based)
✓
Dusk-to-dawn operation with programmable dimming profiles (motion optional)
✓
Surge protection and IP rating aligned to tender or EPC requirements (scope-based)
✓
Installation and acceptance notes provided for mounting interface, wiring, and traceability checks (on request)

Scope & Assumptions

A concise summary of what this reference covers and the verification inputs behind it.
Scope (Reference Deployment)
  • Coverage: all-in-one solar street lighting reference deployment in Sri Lanka, 532 sets (scope-based sections)
  • Use case: EPC / tender workflows requiring verifiable assumptions and auditable notes
  • Deliverables referenced: IES photometry + BOQ notes (on request)
  • Configuration approach: 7m mounting with 80W baseline, layout tuned to road width and targets
Verification Inputs (Assumptions Documented)
  • Pole height: 7 m (reference)
  • Spacing: layout-dependent, documented per section
  • Optics: roadway distribution verified using IES files (on request)
  • Targets: maintained lux & uniformity per project brief (scope-based)
  • Controls: dusk-to-dawn with programmable dimming (motion optional)
Detailed verification inputs can be shared in a redacted pack or under NDA for tender review.

Photos & Acceptance Notes

Field photos confirm the deployment is real. The notes below summarize typical site acceptance checks used by EPC teams to reduce rework and sign-off risk.
Acceptance Notes (Typical)
✓ Bracket / Arm Interface
Verified against drawings (spigot size, orientation, fasteners).
✓ Wiring & Polarity
Checked before commissioning; glands sealed and connectors secured.
✓ Controller Label / ID
Recorded for traceability (batch/serial, configuration version).
✓ Pole Verticality & Base
Checked after installation (verticality, base fastening).
✓ PV Orientation (All-in-One)
Panel direction and shading risks checked before final tightening.
✓ Lux Spot-Check (Optional)
Performed on a representative section for visibility and uniformity.
Tip: Full checklist and traceability tables can be shared in a redacted pack (NDA available).

FAQ (Tender & Verification)

Quick answers to common EPC / tender questions for this reference.
What documents can be shared for tender submission?
Typical items include datasheets and drawings, BOQ mapping notes, and (when required) IES/LDT photometric files and layout outputs. The pack can be aligned to the reviewer checklist and declared assumptions.
Do you provide IES files and layout assumptions for verification?
Yes. Model-matched IES/LDT files can be provided on request for optics verification. Layout assumptions (pole height, spacing intent, road width, targets) can be documented for EPC review.
How is the 7m / 80W all-in-one configuration applied across road segments?
This reference uses 7 m poles with 80 W luminaires as a baseline. Final spacing and optics are selected by road width and maintained lux targets. All-in-one sizing is scope-based and aligned to autonomy and local conditions when confirmed.
Can you share photos and acceptance records under NDA?
Yes. Field photos and typical acceptance notes can be shared in a redacted pack. NDA can be used for traceability items (labels/IDs, configuration records, checklists) when requested by the client.
What inputs do you need to propose a similar 532-set deployment?
Country/city, road type and width, pole height preference, quantity, operating hours and dimming intent, and any targets (lux/uniformity) if specified. If available, share the BOQ/spec so deliverables can be matched to the reviewer scope.
