Solar Lighting Projects/France Tarn-et-Garonne Solar Roadway Lighting Upgrade

500-Set Solar Roadway Lighting Project for an Off-Grid Road Application

Project Location: Tarn-et-Garonne, France
Project Type: Solar Roadway Lighting Upgrade
Product: LED Solar Roadway Lights
Quantity: 500 sets
Rated Power: 130W
Certification: CE / UN38.3
Warranty: 3 years
Energy-Saving Improvement: 25%

LIKELITE supplied a solar roadway lighting system for a road lighting upgrade project in Tarn-et-Garonne, France, where independent solar power was required for roadway illumination.

The project involved the deployment of 500 sets of 130W LED Solar Roadway Lights, combining photovoltaic power generation, battery storage and intelligent lighting control into an independent roadway lighting system.

The project demonstrates LIKELITE's capability in supplying solar roadway lighting equipment for European infrastructure applications where lighting performance, system reliability, energy management and simplified power infrastructure are important project requirements.

Project Requirements

The project required a roadway lighting system capable of operating independently from conventional grid power.

The main project requirements included:

• Solar-powered roadway lighting

• 500 lighting units

• 130W LED roadway lighting

• Outdoor environmental protection

• Independent energy storage

• Intelligent lighting control

• Dimming capability

• Remote control capability

• European market certification requirements

• Long-term outdoor operation

• Reduced energy consumption

The system therefore had to be evaluated as a complete solar lighting installation rather than as a standalone LED luminaire.

Project Scope

LIKELITE's project scope covered the lighting equipment and related engineering support required for system configuration.

Lighting Equipment

Product: LED Solar Roadway Lights
Power: 130W
Quantity: 500 sets
LED Efficiency: 120 lm/W
LED Source: CREE SMD2835
IP Rating: IP66
Solar Cell: Mono-Si
Solar Panel: 36V / 130W
Battery: 25.6V / 90Ah

Lighting Distribution

The reference luminaire uses a 75° × 140° roadway distribution, designed to provide directional light coverage across the road surface rather than relying on a symmetrical floodlight distribution.

This configuration is intended to support roadway lighting applications where pole position, road width and mounting geometry must be considered during lighting design.

Intelligent Control System

The project incorporated multiple lighting control functions:

Microwave Motion Sensor + Light Control + Timer Control

The control architecture allows the operating strategy to be adjusted according to project requirements.

A typical control sequence can include:

Scheduled operation → Dimming → Motion detection → Increased output → Reduced output after activity

This approach reduces unnecessary full-power operation and helps manage battery energy during the night.

Remote control and dimming functions are also supported according to the project configuration.

Solar Power and Battery System

The roadway lighting system operates using solar energy rather than direct grid electricity.

Solar Generation

Solar Panel: 36V / 130W
Solar Cell: Mono-Si

The photovoltaic panel generates electrical energy during daylight hours.

Energy Storage

Battery: 25.6V / 90Ah

The battery stores generated energy for night-time lighting operation.

The final solar and battery configuration should always be evaluated against local solar radiation, required operating hours, installation conditions and required reserve capacity.

For this reason, solar lighting Projects should not be configured from lamp wattage alone.

Engineering Design Support

Before production and project deployment, LIKELITE can support the lighting design process with engineering layouts and simulation.

Available design support includes:

• On-site metering

• Lighting and circuitry design

• DIALux Evo layout

• LitePro DLX layout

• AutoCAD layout

• AGi32 layout

The purpose of the lighting design is to establish the relationship between:

Road geometry → pole position → mounting height → luminaire distribution → lighting coverage → system configuration

This engineering process helps reduce the risk of selecting a solar roadway light without considering the actual installation environment.

Project Technical Configuration

*Charging time is dependent on solar radiation and operating conditions.

Project Execution

01 — Site and Application Assessment

Road conditions and installation requirements were considered before final system configuration.

The key engineering factors include road geometry, pole spacing, mounting conditions, operating schedule and expected lighting demand.

02 — Lighting Design

LIKELITE's engineering support can be used to establish the required luminaire distribution and road lighting layout.

DIALux Evo and other engineering software can be used where project-specific simulation is required.

03 — Solar System Configuration

The solar panel and battery configuration were matched with the 130W roadway lighting system and intended operating conditions.

04 — Intelligent Control Configuration

Microwave sensing, light control and timer control were integrated into the lighting control strategy.

05 — Production and Quality Control

The configured LED solar roadway lights were manufactured according to the confirmed project specification.

06 — Project Delivery

The 500-set system was prepared for deployment as a complete solar roadway lighting application.

Project Performance

The project achieved an estimated 25% improvement in energy-saving performance compared with the previous lighting configuration.

The energy-saving result is associated with the combined effect of:

• High-efficiency LED lighting

• Solar power generation

• Battery energy storage

• Intelligent control

• Motion sensing

• Timer control

• Dimming strategy

This is an important distinction in evaluating solar roadway lighting Projects.

The energy-saving performance should be assessed at the system level, rather than based only on LED wattage.

Why This Project Matters

The Tarn-et-Garonne project provides a practical reference for European solar roadway lighting applications.

It demonstrates that LIKELITE can support Projects requiring:

500-set project supply + solar power + battery storage + roadway optics + intelligent controls + engineering lighting design + European certification support

The project is particularly relevant to:

• Municipal infrastructure contractors

• EPC contractors

• Road engineering companies

• Solar lighting distributors

• Lighting importers

• Infrastructure procurement companies

• European lighting brands

• Off-grid infrastructure developers

Project Lessons for Future Solar Roadway Projects

The project confirms several practical considerations for solar roadway lighting procurement.

Solar Lighting Is a System

Selecting a 130W lamp alone does not determine whether a solar roadway project will perform correctly.

The LED load, solar panel, battery, control system and operating schedule must be considered together.

Roadway Optics Matter

Roadway lighting requires controlled distribution.

The 75° × 140° distribution used in the reference configuration is intended for roadway applications and should be evaluated through project-specific lighting calculations.

Intelligent Control Affects Energy Consumption

Motion sensing, timer control and dimming can reduce unnecessary full-power operation.

Local Conditions Affect Solar Configuration

Solar radiation, temperature, operating hours and battery reserve requirements vary by location.

Therefore, the final configuration should be based on project-specific engineering data.
