Integrated Solar LED Road Lighting Systems for Municipal Roads, Highways, Rural Roads and Infrastructure Projects

LIKELITE provides solar roadway lighting solutions for Projects where grid access, energy consumption, installation conditions and long-term operating costs need to be considered together.

The solution combines LED Solar Roadway Lights, Mono-Si solar panels, lithium battery storage, remote control and intelligent lighting control with professional lighting design and engineering services. LIKELITE supports project requirements from onsite measurement and lighting calculations through system configuration and project implementation.

Solar Roadway Lighting Solution Scope

A solar roadway lighting system is more than a solar panel combined with an LED lamp. The complete system needs to coordinate lighting output, solar generation, battery capacity, charging conditions, operating hours and control strategy.

LIKELITE's solar roadway lighting solution can include:

• LED Solar Roadway Lights

• Mono-Si solar panels

• Battery energy storage

• Remote control

• Microwave motion sensing

• Light control

• Timer control

• Dimming

• Lighting and circuitry design

• Onsite metering

• DIALux Evo layout

• LitePro DLX layout

• AutoCAD layout

• AGi32 layout

• Project engineering support

The final configuration is determined according to the road environment, required lighting level, solar resource, operating schedule and project requirements.

Solar LED Roadway Lighting System Configuration

A representative LIKELITE configuration used for European solar roadway applications includes a 130W LED Solar Roadway Light with integrated solar power and intelligent control functions.

Reference configuration:

This configuration can be adapted according to the actual road geometry, solar conditions, lighting requirements and project operating schedule.

Solar Panel and Energy Generation

Solar generation is a core part of an off-grid roadway lighting system.

The reference configuration uses a:

36V / 130W Mono-Si Solar Panel

Mono-Si technology provides the photovoltaic generation component required to recharge the battery during daylight hours.

Solar system sizing should not be based on panel wattage alone. Engineering evaluation should consider:

• Local solar irradiation

• Seasonal variation

• Geographic location

• Panel orientation

• Panel inclination

• Shading

• Battery capacity

• Required operating hours

• Weather conditions

• Lighting output

• Control strategy

• Required autonomy

For international roadway Projects, the solar generation and battery-storage configuration should therefore be verified against the actual project location.

Battery Energy Storage

The reference system uses:

25.6V / 90Ah Battery

Battery storage provides the energy reserve required for nighttime roadway lighting.

The final battery capacity should be coordinated with:

• LED power

• Daily operating hours

• Dimming schedule

• Motion-sensor operation

• Local solar conditions

• Charging time

• Required backup capacity

• Seasonal operating conditions

The purpose of system design is to maintain the required lighting operation while balancing solar generation, storage capacity and energy consumption.

Intelligent Solar Road Lighting Control

LIKELITE solar roadway lighting solutions can combine several control methods.

Microwave Motion Sensor

Motion sensing can adjust lighting operation according to detected road activity, subject to the configured control logic.

Light Control

Light-control functionality can automatically coordinate the lighting system with ambient light conditions.

Timer Control

Timer control allows operating schedules to be programmed according to project requirements.

Remote Control

Remote control provides an additional method for managing or adjusting the lighting system according to the installed control architecture.

Dimming

The reference configuration supports dimming, allowing lighting output to be adjusted according to the required operating mode.

These functions can be configured individually or as an integrated control strategy.

Solar Road Lighting Energy Management

The main engineering objective of a solar roadway lighting system is to coordinate:

Solar Generation → Battery Storage → LED Lighting → Intelligent Control

During daylight hours, the solar panel generates electrical energy and charges the battery.

During nighttime operation, stored energy powers the LED roadway lighting system.

The control system can then manage lighting output according to the programmed operating strategy.

This approach can reduce dependence on grid electricity and provide a practical option for roads where grid connection is difficult, expensive or unavailable.

Roadway Lighting Design

Solar roadway lighting still requires professional roadway lighting design.

LIKELITE provides lighting design services including:

• Lighting and circuitry design

• Onsite metering

• DIALux Evo layout

• LitePro DLX layout

• AutoCAD layout

• AGi32 layout

Lighting design can evaluate:

• Pole spacing

• Mounting height

• Road width

• Luminaire position

• Beam distribution

• Lighting coverage

• Roadway geometry

• Lighting uniformity

• Solar-panel positioning

Final lighting performance should be verified through project-specific calculations rather than relying only on the nominal luminaire specifications.

Beam Distribution

The reference LED Solar Roadway Light configuration includes:

75° / 140° Cut Out

Beam selection should be coordinated with the actual road geometry and installation arrangement.

Factors affecting the final optical configuration include:

• Road width

• Pole spacing

• Mounting height

• Pole setback

• Road classification

• Required lighting distribution

• Luminaire orientation

For municipal and infrastructure Projects, the final beam configuration should be confirmed through the lighting design.

Outdoor Protection and Environmental Conditions

The reference solar roadway lighting configuration uses:

IP66 protection

and an operating temperature range of:

-25°C to 65°C

The lamp body uses aluminum alloy construction with a glass shade.

These characteristics provide a configuration for outdoor roadway applications exposed to changing weather and environmental conditions.

For each project, the actual installation environment should be reviewed before final equipment selection.

Energy-Saving Design

Solar roadway lighting can reduce grid electricity consumption because the lighting system is powered by solar energy rather than relying entirely on conventional grid power.

Intelligent controls can further manage energy consumption by adjusting operating schedules and lighting output.

Potential energy-management functions include:

• Scheduled operation

• Ambient-light control

• Motion-based operation

• Dimming

• Reduced-output operation during low-traffic periods

• Remote control

Energy performance depends on the complete system configuration and actual operating conditions.

European Project Configuration Reference

The provided system configuration is suitable as a reference for European solar roadway lighting applications.

A representative project specification includes:

• Project Application: Solar Roadway Lighting

The reference configuration includes:

• CE

• DoC

• RoHS

• UN38.3

• MSDS

• ErP

Battery-related documentation is particularly important for international transportation and project procurement.
