Solar Street Lights for Roads, Campuses and Societies
Autonomous, all-in-one solar street lights that switch on at dusk and off at dawn — no trenching, no cabling, and no ongoing electricity bill.
Cable-Free Lighting That Pays for Itself Over Time
A solar street light is a self-contained unit — solar panel, battery, LED fixture and controller integrated onto a single pole — that requires no connection to the electricity grid at all. Since there's no cabling or trenching involved, installation is significantly faster and less disruptive than conventional street lighting, making solar lights especially practical for locations where running new electrical infrastructure would be costly or impractical, such as internal society roads, campus pathways, parks, or rural stretches. Once installed, the built-in controller handles dusk-to-dawn operation automatically, with the battery storing daytime solar charge to power the LED fixture through the night.
Who is this solution suitable for?
Key Benefits
No Trenching or Cabling
Each unit is self-contained, dramatically simplifying installation.
Fully Automatic Operation
Dusk-to-dawn switching handled by the built-in controller.
No Ongoing Electricity Bill
Runs entirely on stored solar energy, with zero grid consumption.
Reliable Battery Backup
Continues operating through cloudy days using stored charge.
How the System Works
- 1 The solar panel atop each pole charges an integrated battery through daylight hours.
- 2 A built-in light sensor and controller automatically switch the LED fixture on at dusk.
- 3 The LED runs through the night powered entirely by the battery's stored solar charge.
- 4 At dawn, the controller switches the light off and the charging cycle begins again.

Available System Capacity
Indicative starting points — final sizing depends on your actual consumption and rooftop or land area.
| System Capacity | Typically Suitable For | Approx. Area Required | Indicative Monthly Generation |
|---|---|---|---|
| 12W – 20W LED | Society internal roads, walkways | 3m – 4m pole height | Dusk-to-dawn, 8–10 hrs backup |
| 30W – 40W LED | Standard roads, campus pathways | 5m – 6m pole height | Dusk-to-dawn, 10–12 hrs backup |
| 50W – 80W LED | Main roads, parking areas | 7m – 8m pole height | Dusk-to-dawn, 10–12 hrs backup |
| 100W+ LED | Highways, large open areas | 9m+ pole height | As per lighting design |

What Affects Your Project Cost
- LED wattage and pole height required for adequate lux coverage
- Number of poles needed based on road length and desired spacing
- Battery capacity for the required backup duration (including cloudy days)
- Civil work needed for pole foundations at each location
- Optional features such as motion sensors or dimming schedules
Estimated Savings Potential
Because solar street lights don't draw grid electricity at all, the ongoing cost of outdoor lighting drops to essentially zero after installation, compared to the recurring electricity bill and cabling maintenance cost of conventional street lighting.

Calculate Your SavingsSubsidy Applicability
Solar street lights for private properties (societies, campuses, commercial premises) are generally a direct purchase without a specific subsidy scheme. Municipal or government-led street lighting projects are sometimes funded through dedicated public infrastructure or CSR programmes, which follow separate tendering processes rather than the residential rooftop subsidy scheme.

For larger multi-pole projects (societies, campuses, institutions), finance options may be available depending on project size and the finance partner's policy — discuss bulk project financing with our team.
Explore EMI & FinanceMaintenance Requirements
Solar street lights need occasional panel cleaning (dust reduces charging efficiency) and periodic battery health checks, particularly as batteries approach the later years of their expected lifecycle. Fixtures are designed to be largely maintenance-free otherwise.

Solar Street Light — Frequently Asked Questions
No — each unit is fully self-contained with its own panel and battery, requiring no grid connection or cabling at all.
This depends on battery capacity and LED wattage; most standard units are designed for a full dusk-to-dawn operating cycle, including a few cloudy-day reserve hours.
Battery capacity is typically sized with a reserve for a few consecutive low-sunlight days; extended poor weather beyond this may reduce operating hours until charging recovers.
This depends on road length, desired lux level and pole height — our site survey provides a specific pole-spacing recommendation.
Private property installations are generally a direct purchase without a specific subsidy; municipal projects sometimes access separate public infrastructure funding through tendering processes.
Periodic panel cleaning and occasional battery health checks are typically sufficient; fixtures are otherwise designed to be largely maintenance-free.
Yes, motion-sensor and dimming-schedule options are available as add-on features depending on the fixture model chosen.
This varies by battery chemistry and usage; lithium-based batteries used in most modern solar street lights are designed for several years of reliable service under normal conditions.
In some cases retrofit fixtures can be mounted on existing poles, though a dedicated pole is generally recommended for optimal panel orientation — assessed during site survey.
