SOLAR FIRST • GRID BACKUP • NEVER GO DARK
Hybrid Solar Street Light
A hybrid solar street light combines the energy savings of solar power with the reliability of grid backup. Battery power is always prioritized for nighttime lighting, while the system automatically switches to grid power only when the available battery energy becomes insufficient. It is ideal for critical roads and locations with limited daily sunlight where uninterrupted lighting is essential.

Automatically switches to grid power whenever battery energy becomes insufficient, ensuring continuous lighting throughout the entire night.
Battery power is prioritized. Grid power is used only when required, helping reduce electricity consumption while maintaining reliable lighting.
Supports luminaires up to 200W, making it suitable for highways, municipal roads and other high-demand lighting applications.
Source switching is automatic and instantaneous — no flicker, no manual intervention.
Combining solar energy with automatic grid backup delivers dependable illumination during extended cloudy or rainy periods.
Solar energy supplies the light whenever possible, while grid power is used only when battery energy becomes insufficient.
Hybrid technology is available for both All-in-One and All-in-Two solar street lights without changing the operating principle.
Perfect for shaded urban areas, high-rise environments and locations where daily solar charging may be insufficient.

Frequently Ask Questions
What is a hybrid solar street light?
A hybrid solar street light combines solar power and grid power in one system. It prioritizes battery power for lighting and automatically switches to grid power only when the available battery energy becomes insufficient, ensuring continuous nighttime illumination.
How does the hybrid system work?
The system uses solar energy to charge the battery during the day. At night, the light is powered by the battery first. When the available battery energy becomes insufficient, the system automatically switches to grid power, ensuring the light remains on throughout the night.
Does the grid charge the battery?
No. The grid does not charge the battery. Grid power is used only to power the LED light when the available battery energy is no longer sufficient, ensuring uninterrupted lighting.
Will excess solar energy be fed back into the electrical grid?
No. Once the battery is fully charged, the solar charging process automatically stops. The system does not export electricity to the grid. It is designed for battery-first lighting with automatic grid backup, not for grid-tied (on-grid) applications.
Will the light automatically switch to grid power?
Yes. The controller continuously monitors the available battery energy and automatically switches to grid power whenever necessary, keeping the light operating throughout the entire night.
Where are hybrid solar street lights best suited?
Hybrid solar street lights are ideal for main roads, highways, municipal roads, industrial parks and other critical infrastructure projects where uninterrupted lighting is required, even during extended cloudy or rainy periods.
Can hybrid technology be applied to both All-in-One and All-in-Two solar street lights?
Yes. Hybrid solar street lights are ideal for urban areas with limited sunlight due to surrounding buildings, trees or other shading obstacles. They are commonly used not only on critical roads, but also in locations where daily solar charging may be insufficient. The system automatically switches to grid power whenever the available battery energy becomes insufficient, ensuring uninterrupted nighttime lighting.
Can I use a hybrid solar street light in areas with limited sunlight?
Yes. Hybrid solar street lights are ideal for urban areas with limited sunlight due to surrounding buildings, trees or other shading obstacles. They are commonly used not only on critical roads, but also in locations where daily solar charging may be insufficient. The system automatically switches to grid power whenever the available battery energy becomes insufficient, ensuring uninterrupted nighttime lighting.
Can the hybrid system be customized?
Yes. We provide customized hybrid solutions, including lighting programs, solar panel and battery configurations, external manual switch cables, and project-specific designs to meet different application requirements.
What warranty do you provide?
All DEL Hybrid Solar Street Lights come with a standard 5-year warranty. Extended warranty options of up to 10 years are also available for selected projects and customized configurations.
