Solar Lighting Solutions/Solar LED Roadway Lighting Solutions for Urban and Municipal Roads

LIKELITE provides solar lighting solutions for urban roads, municipal streets, public infrastructure and roadway lighting Projects.

The solution combines LED Solar Roadway Lights, solar panels, batteries, intelligent controls, lighting design and engineering services into a complete solar-powered roadway lighting system.

LIKELITE supports project requirements from onsite metering and lighting design to solar system configuration, lighting simulation and project engineering support.

The objective is to provide a roadway lighting system that can operate independently from conventional grid power where the project conditions are suitable for solar lighting.

Solar Roadway Lighting System

A solar roadway lighting system typically consists of:

• LED Solar Roadway Lights

• Solar Panel

• Solar Battery

• Solar Controller

• Intelligent Lighting Control

• LED Light Source

• Remote Control

• Motion Sensor

• Light Control

• Timer Control

• Lighting Design

• Circuitry Design

• Lighting Simulation

The system converts solar energy into electrical energy during the daytime and stores energy in the battery for nighttime lighting operation.

The final solar configuration should be determined according to local solar conditions, required lighting hours, roadway geometry, load demand and project operating requirements.

Solar Lighting for Urban Roads

LIKELITE Solar Lighting Solutions can be considered for:

• Municipal roads

• Urban streets

• Residential roads

• Secondary roads

• Rural roads

• Public roads

• Parking areas

• Pedestrian routes

• Remote roads

• Infrastructure Projects

• Roadway lighting renovation

• Off-grid lighting projects

Solar roadway lighting can be particularly useful where extending conventional grid infrastructure is difficult, expensive or unsuitable.

Integrated Solar LED Roadway Light

For large-scale roadway projects, the luminaire, solar panel, battery and control system should be considered as one system rather than as independent components.

A reference LIKELITE configuration includes:

The actual configuration should be confirmed against the project load calculation and local solar conditions.

Solar Panel Configuration

The reference system uses a:

36V 130W Mono-Si Solar Panel

Mono-Si solar cells are used to convert solar radiation into electrical energy during daylight hours.

Solar panel selection should consider:

• Local solar radiation

• Panel orientation

• Installation angle

• Seasonal conditions

• Daily energy demand

• Required lighting duration

• Battery capacity

• System losses

Solar panel capacity should not be selected only according to lamp wattage.

The complete daily energy balance should be evaluated.

Solar Battery System

The reference configuration includes:

25.6V 90Ah Battery

Battery capacity directly affects nighttime operating capability.

The battery configuration should be evaluated against:

• LED load

• Required operating hours

• Local solar conditions

• Charging time

• Battery depth of discharge

• Backup requirements

• Seasonal variation

• Expected service conditions

The reference system specifies a charging time of approximately:

5–6 Hours

Actual charging performance depends on solar radiation, panel orientation, weather and system operating conditions.

Intelligent Solar Lighting Control

LIKELITE can integrate multiple control functions into the solar roadway lighting system.

Microwave Motion Sensor

The microwave motion sensor can detect movement and support adaptive lighting operation.

For roads with changing traffic levels, lighting output can be adjusted according to the configured control strategy.

Light Control

Light control enables automatic lighting operation based on ambient light conditions.

This helps prevent unnecessary operation during daylight hours.

Timer Control

Timer control provides scheduled operation according to the project requirements.

Lighting schedules can be configured for different nighttime periods.

Remote Control

Remote control can provide a convenient method for managing or configuring the lighting system according to the selected control architecture.

Solar Lighting with Dimming

The reference system supports dimming.

Dimming can be combined with motion detection and scheduled control to reduce unnecessary lighting output during periods of low road activity.

A typical operating strategy can be:

Evening → Normal Lighting → Low-Traffic Period → Dimming → Motion Detection → Lighting Increase

The exact dimming levels and operating periods should be determined during project design and commissioning.

Solar Lighting Design

Solar roadway lighting design requires both lighting calculations and energy-system calculations.

LIKELITE can evaluate:

Roadway Lighting

• Road width

• Pole height

• Pole spacing

• Luminaire position

• Beam distribution

• Required illumination

• Uniformity

• Mounting angle

Solar System

• Solar panel capacity

• Battery capacity

• Daily energy consumption

• Charging conditions

• Operating hours

• Seasonal solar availability

• Backup requirements

This ensures that the lighting system is designed around the actual project rather than only around the luminaire wattage.

Lighting Simulation

LIKELITE supports professional lighting design and simulation using:

DIALux Evo

For roadway modeling, luminaire positioning and lighting calculations.

LitePro DLX

For luminaire layout and lighting analysis.

AutoCAD

For roadway layouts, pole positions and engineering drawings.

AGI32

For additional roadway lighting calculations and engineering verification.

Lighting simulation allows the proposed solar LED roadway light configuration to be evaluated before installation.

Onsite Metering

Onsite metering can be used to collect actual project information before final system configuration.

Typical information includes:

• Road width

• Pole height

• Pole spacing

• Existing lighting

• Road geometry

• Existing electrical infrastructure

• Installation position

• Environmental conditions

For renovation projects, onsite data can significantly improve the accuracy of the final lighting layout.

Lighting & Circuitry Design

LIKELITE provides lighting and circuitry design support for solar roadway lighting projects.

Engineering considerations include:

• Luminaire layout

• Solar panel configuration

• Battery configuration

• Controller arrangement

• Cable routing

• Electrical protection

• Control architecture

• Installation planning

The design should coordinate the lighting system and solar power system rather than treating them as separate engineering tasks.
