All-in-Two Solar Street Light
All-in-Two Solar Street Lights for Roads & Public Areas
An All-in-Two solar street light uses a separate PV panel and a coordinated luminaire arrangement. Review panel direction and tilt independently from the light head, while keeping a more coordinated installation than a full split system. Confirm road geometry, energy requirements, mounting, wiring and maintenance access before selecting a configuration.

How All-in-Two Architecture Works
Separate PV placement creates useful flexibility. The panel, luminaire, wiring and maintenance plan still need to be reviewed as one system.
Coordinated AIT Body
- Separate PV panel and coordinated luminaire; often described as semi-integrated.
- Confirm battery/controller arrangement for the selected configuration.
- External appearance alone does not establish internal components or service method.
PV Direction & Tilt
- Review solar resource, road direction and shading together.
- Check available bracket adjustment against the site.
- Panel position must suit the mounting conditions.
Wiring & Installation Access
- Coordinate cable routes, connector protection and pole interfaces.
- Drawings must identify secure mounting and protected connections without obstructing service access.
- AIT needs more PV-mounting coordination than AIO; Split introduces greater component separation.
Service & Maintenance
- Confirm battery-pack arrangement and replacement access for the selected configuration.
- Check replacement-part compatibility and safe cable disconnection.
- Structure images show mounting and connections, not a verified battery-removal procedure.
PV and connection arrangement
Review the PV position, cable route and protected connections as one installation arrangement.
Separate PV mounting arrangement
Check panel clearance, bracket adjustment and pole interfaces against the site mounting conditions.

AIT Selection Paths
Choose the review path that matches your project and procurement requirements.
01
Standard All-in-Two
For municipal and EPC road-lighting projects that need separate PV orientation and a coordinated luminaire, mounting and wiring arrangement. Start with road geometry, operating hours, solar conditions and the maintenance plan.
02
Government / Tender All-in-Two
For consultant, EPC and municipal tender workflows that require project configuration review and model-matched engineering files. Share the BOQ, lighting criteria and drawings to coordinate IES, DIALux and technical submittal requirements.
The exact model, component configuration and document set are confirmed during project review.
Choose the Right Architecture
All-in-One
Choose when the integrated assembly and compact installation fit the site’s solar exposure, mounting and maintenance requirements. Review All-in-One Solar Street Lights.
All-in-Two
Choose when separate PV direction and tilt are useful while retaining a coordinated, relatively compact luminaire arrangement.
Split
Review when panel or battery position, cable routing or maintenance requires greater component separation. Review Split Solar Street Lights.
Engineering & Tender Support
The document set depends on the confirmed model, optics, component configuration and project stage. Project-specific files remain available through request and engineering review.
IES / LDT
Request photometry matched to the confirmed model, optic and component configuration. The file identifies the distribution used for layout calculations; a generic family file cannot establish the performance of every luminaire. Confirm the proposed optic before the consultant completes the lighting review.
DIALux / Relux
Review the road geometry, lighting target and selected photometry together. Supply road width, mounting height, pole arrangement and spacing, together with the applicable illuminance, luminance or uniformity criteria. The simulation inputs should reflect the proposed layout and the model-matched optical file.
Datasheets / Drawings / Wiring
Confirm the model, mounting interface and system architecture before preparing the applicable files. Coordinate luminaire and PV bracket dimensions, cable routes, connector protection and service access. The final technical submittal should use consistent configuration references across the datasheet, assembly drawing and wiring information.
BOQ / Tender Review
Coordinate product scope, quantities, technical requirements and the document schedule. Identify the required luminaire, solar components, poles, arms and installation interfaces, together with the consultant’s submission requirements. Record unresolved assumptions before treating a preliminary selection as an approved project BOM.
Available certificates and test reports must be checked against the relevant holder, standard, validity and confirmed model or component scope. Submit the project requirements for a model-matched document review.
Start with Engineering Support when the required file set is not yet clear. Project-specific engineering files are supplied through request and review, with the release scope matched to the procurement stage.

Luminaire aging checks
Aging and operating checks form part of the agreed quality workflow. Inspection scope follows the confirmed order.
Photometric & electrical testing
Review the applicable photometric and electrical evidence against the selected luminaire, optic and configuration.
Configuration, Quality & Delivery

All-in-Two Project Questions
Practical questions to resolve before model selection, tender review or production.
What is the difference between All-in-Two and All-in-One?
All-in-Two uses a separated PV panel so its direction and tilt can be reviewed independently from the light head. It is not simply a higher-power AIO. Confirm the selected component arrangement, mounting, wiring and service access.
When should All-in-Two be selected instead of Split?
Review AIT when separate PV orientation is useful and the coordinated luminaire arrangement suits the site. Review Split when separate battery placement or greater component-location flexibility is needed, allowing for additional wiring and installation coordination.
Why does PV direction and tilt matter?
Solar exposure varies with location, season, road direction and shading. The panel position and available adjustment must be checked against the bracket, pole and local mounting conditions.
What project information is needed before configuration?
Send the country and city, road width, pole height and spacing, nightly hours, dimming profile, autonomy target, quantity and required documents. Add site or pole drawings and photographs where available.
How are autonomy and energy requirements reviewed?
Autonomy depends on local solar resource, the operating profile, usable battery energy and system losses. Review the PV panel, battery and controller together against defined low-solar operating assumptions.
What wiring and mounting details must EPC teams confirm?
Confirm the pole interface, luminaire and PV mounting points, cable route, connector protection and maintenance access. Final wiring and installation documents must match the selected configuration.
Can Sunlurio provide IES/LDT, DIALux, drawings and BOQ support?
Yes. The applicable files are reviewed against the confirmed model, optic, component configuration and project stage. Submit the road geometry, BOQ or tender requirements to identify the required document set.
How is the final configuration confirmed before production?
Confirm the model and component configuration, lighting and energy assumptions, mounting and wiring arrangement, document list and agreed inspection scope. Packing, shipment preparation and written commercial terms should be reviewed before release.
