586 TRANSFO Solar Street Lights for a Road Project in Bangladesh

For this large-scale road lighting project in Bangladesh, Inbrit supplied 586 sets of TRANSFO split solar street lights.

Each system was configured with a 200W four-module LED luminaire, 360W solar panel, 25.6V 100Ah battery and 7.15-meter light pole.

The completed installation demonstrates how a split solar street lighting system can be configured for large roadway projects that require independent solar power, high-output LED lighting and scalable installation.

Project Configuration

200W TRANSFO Split Solar Street Light

The project uses Inbrit’s TRANSFO split solar street light, configured with a four-module 200W LED luminaire.

The TRANSFO series uses a split-system design in which the solar panel, energy-storage system and LED luminaire can be configured according to individual project requirements. Inbrit’s current TRANSFO product range supports rated powers up to 200W and recommended installation heights from 6 to 15 meters.

Solar Power Configuration for the Bangladesh Project

Each lighting system uses a 360W solar panel together with a 25.6V 100Ah battery.

For a solar roadway project, the solar panel, battery, controller and luminaire should be treated as one complete energy system rather than selected independently.

The system configuration needs to consider factors such as:

• Local solar conditions

• Required lighting hours

• LED power

• Battery capacity

• Road layout

• Pole height and spacing

This project configuration was selected for the actual requirements of the Bangladesh installation.

7.15m Pole Height for Road Lighting

The lights are installed on 7.15-meter poles, positioning the 200W LED luminaires above the roadway for broad illumination.

Light Pole height is an important part of roadway lighting design because it affects beam spread, fixture spacing and light distribution.

For other road projects, Inbrit recommends evaluating pole height together with road width, spacing and optical distribution rather than selecting wattage alone. Inbrit’s roadway solution guidance similarly identifies road width, pole height, spacing and optical distribution as key selection factors.

Installation and On-Site Assembly

The project photos document both the installation process and the completed system.

During installation, the solar panels, LED luminaires and mounting structures are assembled and secured before the poles are erected.

For a project involving 586 lighting points, consistent installation and system checking are particularly important because the same configuration needs to be reproduced across many locations.

Inbrit also applies solar street light quality control procedures to evaluate key components and system performance before project delivery.

Night-Time Road Lighting Effect

The completed project photos show the TRANSFO solar street lights operating along the roadway at night.

Multiple lighting points are arranged along both sides of the elevated road, creating continuous illumination across the project area.

The actual images provide useful project proof of the installed configuration and allow customers to see the final lighting result rather than relying only on product specifications.

Solar Street Light Technology Behind the System

A complete split solar street lighting system depends on the coordination of the solar panel, battery, controller and LED luminaire.

For buyers evaluating large road projects, understanding the relationship between these components is important when determining daily operating time, charging performance and lighting strategy.

Why Split Solar Street Lights for Large Road Projects?

Split solar street lights are particularly suitable for projects where the solar panel and battery system need to be configured independently according to local project conditions.

For large roadway installations, this provides flexibility in:

• LED power selection

• Solar panel sizing

• Battery capacity

• Pole height

• Panel orientation

• Operating schedules

The TRANSFO range itself supports flexible power and component customization for different road applications.
