Solar Street Light Systems for EPC, Municipal & Public Lighting Projects
Choose All-in-One, All-in-Two or Split architecture around your road layout, installation conditions and maintenance plan. Working hours, dimming, local solar conditions and the required autonomy then guide the PV and battery configuration.
Start with your project conditions
Share the country and city, road width, pole height and spacing, lighting schedule, and backup target. Add your BOQ or drawing link if available. Unknown inputs can be marked “To be confirmed.”
Choose Your Solar System Architecture
The architecture describes how the luminaire, PV panel and battery are arranged. It does not, by itself, determine the lighting output or backup performance.
All-in-One
An integrated assembly combines the luminaire, PV panel and battery. It reduces separate component mounting, while panel orientation and service access depend on the selected design. Check the available solar exposure, mounting arrangement and maintenance method before choosing the model.
All-in-Two
A separate PV panel works with a luminaire assembly that incorporates the battery in the selected configuration. The panel can be positioned separately from the light head, subject to the mounting design. Review the panel bracket, cable route and access to the battery and luminaire during maintenance.
Split
The luminaire, PV panel and battery are arranged as separate components. This provides more placement options but requires coordinated mounting, wiring, battery protection and service access. Confirm the pole, battery location, cable protection and installation responsibilities for the site.
Solar Energy & Autonomy Design Logic
Energy design follows project conditions. A wattage label or a stated number of backup days is not enough to define a reliable solar lighting configuration.

Define the lighting duty
Start with the road geometry and required lighting performance. Establish the nightly operating hours and dimming schedule so the energy demand reflects how the lights will actually operate.
Review the solar resource
Use the project location, seasonal solar conditions and potential shading to assess the charging opportunity. PV sizing and orientation must be reviewed together with the mounting space and site conditions.
Match usable battery energy to the backup target
The autonomy requirement must be considered alongside the lighting schedule, dimming profile, battery operating limits and local conditions. A backup-days claim needs defined operating assumptions; it is not a universal guarantee across climates or configurations.
Coordinate the controller and environment
Review charging and dimming control, battery protection, temperature exposure and the installation arrangement as a system. Confirm the selected components and operating settings before treating a configuration as ready for procurement.
The review should produce a project-specific configuration and a clear list of assumptions to confirm. No single PV-and-battery combination is suitable for every solar street lighting project.
AIO vs AIT vs Split: Procurement Comparison
Compare the installation and service implications first. Confirm model-level performance and documents against the final configuration.

Project Inputs & Risk Review
Send what you know now. Missing dimensions or operating assumptions can be identified during the review; you do not need a finished design to start the conversation.
Country, city and site conditions
Seasonal solar resource, shading and temperature can change the energy review.
Road width, pole height and spacing
These affect the lighting layout and photometric review; wattage alone does not establish coverage.
Working hours and dimming schedule
An undefined operating schedule can lead to an unsuitable energy configuration.
Autonomy or rainy-day target
The backup requirement needs a defined lighting schedule and operating assumptions.
Pole, mounting and installation conditions
Check brackets, cable routing, access, security and responsibilities before choosing an architecture.
BOQ, drawings and required documents
These align the offered configuration with procurement and tender requirements.
If a required form field is not yet known, enter “To be confirmed” and describe the available information in the notes. Share a BOQ or drawing link where available.
Engineering & Tender Documents
Request the documents needed for your selection or tender review. Availability and scope depend on the confirmed model, configuration and project stage.
IES / LDT
Request photometric files matched to the selected luminaire and optical configuration. A generic file should not be treated as valid for every model.
DIALux / Relux
Share the road layout, mounting height, spacing and lighting criteria for a project-specific simulation review.
Datasheets & Drawings
Request configuration-matched datasheets and relevant mounting, wiring or installation drawings. Foundation references and test reports are reviewed where applicable.
BOQ / Tender Review
Share the BOQ and specification to align the component schedule, document list and items requiring clarification.
Document previews only. Project files are provided through request and review against the confirmed configuration.

Solar Street Light Selection FAQ
No. All-in-One, All-in-Two and Split describe component arrangements. The suitable output and energy configuration must be confirmed for the selected model, road layout, operating schedule and local solar conditions. Do not assume that one architecture automatically provides higher power or longer backup.
No. Review road width, pole height, spacing, required lighting performance and the nightly schedule first. Then assess the architecture, PV and battery configuration, installation conditions and maintenance access.
Compare solar exposure, panel orientation, component placement, cable routing and service access. All-in-One provides an integrated arrangement; All-in-Two separates the PV panel; Split requires coordination of separate components. Confirm the details against the selected model and site.
Share the country and city, road width, pole height and spacing, working hours, dimming and backup target. Include a BOQ or drawing link if available. If an input is unknown, mark it “To be confirmed” and send the information you already have.
Yes. Request the relevant files or review scope against the selected model and project stage. Photometric files, simulations and drawings must correspond to the configuration under review; one generic document is not evidence for every system.
The lighting duty, working hours, dimming profile, local solar resource, seasonal conditions and backup target all matter. Controller settings, battery operating limits and temperature also need review. A backup-days statement is meaningful only with its operating assumptions.
Share the BOQ, drawings and specification for review. The configuration, component schedule and document list can then be checked for alignment, with any missing inputs or exceptions identified before procurement.
