Project Background
This reference deployment in Sri Lanka uses 300 sets of 60W all-in-one solar street lights on 6m 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.

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 6m / 60W all-in-one configuration applied across road segments?
This reference uses 6 m poles with 60 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 300-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.
