A solar street light charges its lithium battery by day and powers the LED luminaire from dusk to dawn.

How solar street lighting works

A solar street light is a self-contained power system on a pole. It generates, stores and uses its own energy every 24 hours, independent of the grid — which is why it keeps working through load shedding and where no grid supply exists.

1
Daytime
Solar panel charges the battery
Sunlight on the panel produces DC power. The charge controller regulates it and charges the lithium battery while the light stays off.
2
Dusk
Automatic switch-on
When panel voltage falls at sunset, the controller detects darkness and switches the LED light on — no grid connection or timer wiring needed.
3
Night
Battery powers the LED
The battery supplies the LED through the night. Programmed dimming — or motion-based brightness where specified — reduces energy use during low-traffic hours.
4
Dawn
Switch-off and recharge
At sunrise the controller turns the light off and the charging cycle begins again. Battery reserve is sized to carry the light through cloudy days.

The complete solar street lighting system

Reliability depends on how the parts work together. AmpereX can supply the complete system or the specific components a project needs, with panel, battery, controller and luminaire matched to each other.

Solar panels

Photovoltaic modules convert daylight into DC electricity. Panel wattage and tilt are chosen from the site's solar conditions and the daily energy the light needs, with margin for dust, heat and shorter winter days.

Solar-powered LED street lights

LED luminaires deliver the required illumination at low wattage. LED power, optics and mounting height are matched to the road width, pole spacing and the lighting level the site requires.

Lithium & LiFePO4 batteries

The battery stores daytime solar energy for night operation. AmpereX specifies lithium chemistry, and LiFePO4 where appropriate, for its cycle life, stable voltage and suitability for daily charge–discharge.

Battery enclosures

Pole-mounted, integrated or ground-level enclosures protect the battery from rain, dust, direct sun and tampering. Enclosure design considers ventilation and heat, which strongly affect battery life in Pakistan's summers.

Solar charge controllers

The controller manages charging from the panel, protects the battery from overcharge and deep discharge, and switches the light on at dusk and off at dawn. Dimming schedules can be programmed to extend autonomy.

Wiring & protection

Correctly rated cabling, fusing, connectors and surge protection keep the system safe and reliable, and make fault-finding straightforward during maintenance.

Mounting systems

Panel brackets and luminaire arms are selected for the pole diameter, panel size and local wind loading, keeping the panel at the correct angle and orientation.

Street-light poles & installation

Where new poles are required, pole height, foundation and spacing are planned together with the lighting layout. Installation covers foundations, erection, mounting, wiring and commissioning.

Lithium battery storage for solar street lights

The battery determines whether a solar street light still works after several years and through a run of cloudy days. As a lithium battery engineering company, AmpereX selects the chemistry, capacity and protection for each project, and integrates the battery with the solar panel and charge controller.

Why lithium for street lighting

A street light cycles its battery every night. Lithium chemistry — and LiFePO4 in particular — is well suited to this daily charge–discharge pattern, with a longer cycle life and more usable capacity than lead-acid.

Heat and placement

High summer temperatures shorten the life of any battery. Enclosure location, shading and ventilation are part of the design, not an afterthought.

Battery management

Lithium packs are paired with protection — through an integrated BMS and a compatible charge controller — against overcharge, over-discharge, over-current and short circuit.

Matched to the controller

Charging voltages and cut-off points are configured for the chosen chemistry, so the controller and battery work as one system rather than as separate parts.

Existing-pole conversion or new-pole installation

Solar street lighting can be added to infrastructure that already exists or built from the ground up. The choice is made per site after assessing the poles, layout and lighting requirement.

Integration with existing poles

Suitable where existing poles are structurally sound, correctly spaced and have space for a panel and battery enclosure
Removes dependence on grid supply and underground street-lighting cabling
Useful for societies and streets where grid-fed lights fail during load shedding
Each pole is assessed for height, condition, load capacity and panel orientation before conversion

New street-light pole installations

Best for new roads, developing phases, parks and sites with no existing lighting infrastructure
Pole height, spacing and luminaire layout are designed together from the start
No trenching for power cables between poles
Foundations and mounting are specified for the panel size and local wind conditions

How a solar street light system is sized

There is no single correct solar street light specification. Each system is engineered from the factors below. The basic chain is: LED power × lighting hours gives nightly energy use; backup days and depth-of-discharge set battery capacity; and local sun hours set the panel wattage needed to recharge it.

Factors used to size a solar street lighting system
Factor	What is assessed	Effect on the design
LED power	Wattage of the luminaire, set by road width, mounting height and required light level	Directly sets nightly energy use
Lighting hours	Dusk-to-dawn, fixed hours, or a dimming profile through the night	Multiplies LED power into daily Wh
Solar conditions	Sun hours by city and season, shading from trees or buildings, dust exposure	Sets panel wattage needed to recharge daily
Battery capacity	Usable Wh after depth-of-discharge and temperature allowances	Carries the light through the night
Backup requirement	Number of low-sun or cloudy days the system must operate through	Adds reserve capacity beyond one night
Pole configuration	Pole height, arm length, single or double luminaire, panel mounting space	Constrains panel size and light distribution
Site conditions	Wind exposure, heat, flooding risk, security and access for maintenance	Drives enclosure, mounting and battery placement
Project requirements	Number of points, layout, phasing, aesthetics and maintenance planning	Shapes the overall system design and rollout

Where solar street lights are used

Solar street lighting suits public and private infrastructure, and is especially useful where grid-fed lighting is interrupted by load shedding or where running cables between poles is costly.

Housing societies

Main boulevards, internal streets, gates and green belts in developments such as DHA, Lake City, Bahria Town and other residential societies.

Roads & streets

Access roads, link roads and internal streets where grid-fed lighting is unreliable or cabling is costly.

Parks & public spaces

Parks, walking tracks, playgrounds and community spaces that need safe night-time lighting.

Commercial areas

Markets, commercial blocks and plazas, with lighting that continues through grid outages.

Industrial areas

Factory perimeters, estate roads, yards and boundary walls for security lighting.

Parking areas

Open parking lots for societies, hospitals, schools and commercial buildings.

Rural communities

Villages and rural roads where the grid is absent, unreliable or far away.

Remote locations

Off-grid sites, farms, highway points and facilities where cabling is impractical.

Solar street lights: frequently asked questions

What does a complete solar street lighting system include?

A complete system includes the solar panel, LED street light, lithium or LiFePO4 battery, battery enclosure, solar charge controller, wiring and protection, mounting hardware and, where needed, the street-light pole and installation. AmpereX can supply the full system or the specific parts a project requires.

How do solar street lights work at night?

During the day the solar panel charges the battery through a charge controller. At dusk the controller detects falling panel voltage and switches the LED on; the battery powers it through the night, often with a dimming schedule, and the light switches off at dawn when charging resumes.

Can solar street lights be installed on existing poles?

Yes, where technically suitable. Existing poles are assessed for structural condition, height, spacing and space to mount the panel and battery enclosure. Where poles are unsuitable, or none exist, new poles are designed and installed as part of the project.

Why use lithium or LiFePO4 batteries in solar street lights?

Street-light batteries are cycled every night. Lithium, and LiFePO4 where appropriate, offers long cycle life, stable voltage and more usable capacity than lead-acid, which suits daily solar charging and discharging.

How is a solar street light sized?

Sizing starts from LED power and lighting hours to find nightly energy use, then accounts for local solar conditions, battery depth-of-discharge, temperature, the number of backup days required, pole configuration and site conditions. Each project is engineered individually rather than using one fixed specification.

Are solar street lights suitable for housing societies?

Yes. Housing societies such as DHA, Lake City, Bahria Town and other residential developments use solar street lighting for boulevards, internal streets, parks and gates, keeping lights on during grid outages without underground cabling between poles.

Which cities does AmpereX cover for solar street lighting projects?

AmpereX provides solar street lighting projects throughout Pakistan, including Lahore, Islamabad, Rawalpindi, Karachi, Multan, Faisalabad, Sialkot, Gujranwala, Peshawar, Quetta, Hyderabad, Bahawalpur, Sargodha, and other cities and rural areas.

Do solar street lights work during load shedding?

Yes. Solar street lights run independently of the grid from their own battery, so load shedding and grid faults do not switch them off.
