Solar Street Light Retrofit
Upgrade existing street lighting to solar while retaining existing poles wherever technically suitable. Reduce trenching, cabling and civil work with a project-specific retrofit solution designed around your existing infrastructure.

Project-Specific
Upgrade the lighting. Keep the infrastructure.
Replacing an existing street-lighting network does not always mean replacing everything. Where existing poles and foundations remain suitable, DEL can engineer a solar retrofit around the infrastructure already in place — reducing unnecessary demolition, trenching, cabling and civil work.
We review the existing poles, road geometry, lighting requirements and local solar conditions before selecting the appropriate luminaire, solar module, battery and mounting configuration. The result is a project-specific upgrade designed to move existing street lighting to solar with less disruption and lower infrastructure cost.
Municipalities upgrading existing street-lighting networks to solar.
EPC contractors working on road rehabilitation and lighting retrofit projects.
Projects where existing poles and foundations are still suitable for reuse.
Sites where trenching, cabling or grid extension would add significant cost and disruption.
From existing infrastructure to a solar retrofit.
Review existing pole dimensions, road geometry and site information provided by your project team.
Define target lighting levels, operating hours and local solar conditions for the retrofit design.
Configure the luminaire, solar module, battery, optics and mounting components for the existing poles.
Verify illumination, uniformity and pole spacing through project-specific photometric calculations before finalizing the design.
Prepare the retrofit systems, mounting components, drawings and technical documents for local installation.
Everything needed for a project-ready retrofit.
A complete retrofit package engineered around your existing poles, road conditions and lighting requirements — ready for your local team to install.
Solar lighting equipment configured around your existing poles and road requirements.
Adapted brackets and mounting components for the existing pole structure.
Photometric calculations verifying illumination, uniformity and pole spacing.
Installation drawings and mounting details prepared for the retrofit configuration.
Datasheets, IES files and technical documents for project review and approval.
Remote guidance for your local team during installation and commissioning.
Before you ask
Still unsure? Send your project details and an engineer will answer directly — usually the same working day.
In many projects, yes. We review the pole height, diameter, top or arm structure and mounting interface to determine the appropriate retrofit configuration. Final suitability remains subject to the existing pole condition and structural requirements.
Typically, we need pole dimensions, pole spacing, road width, existing luminaire details, site photos, required lighting levels and the project location for solar-resource assessment.
Yes. For qualified projects, DIALux calculations can be used to verify illumination, uniformity, pole spacing and the proposed optical configuration before the final system is confirmed.
No. DEL provides the retrofit system, mounting solution, drawings, technical documentation and remote technical support. Physical installation is carried out by your local contractor or project team.
