Street Light

Street Light

Solar streetlights are community lighting units that convert sunlight into electricity during the day and automatically illuminate public areas at night. By integrating solar panels, batteries, lamps and controllers into a single system, these systems require no external wiring and can operate off‑grid. SELCO’s designs use high‑efficiency LEDs for bright light with low energy use, and sensors to switch on at dusk and off at dawn.

Major Components

Solar Panels

Converts sunlight into DC electricity. Common types are monocrystalline and polycrystalline panels, chosen for their conversion efficiency and durability.

Rechargeable Battery

Stores generated energy for nighttime use. Lithium‑ion are typically used by SELCO, offering multi‑year lifespans and deep‑cycle capacity.

LED Light Fixture

Provides bright, efficient illumination. LEDs consume up to 50% less energy than traditional lamps and switch on instantly without warm‑up.

Twilight Sensor

Detects ambient light levels and triggers automatic on/off switching at dusk and dawn.

Pole & Mounting Hardware

Supports the panel and fixture, designed for wind resistance and easy installation. Brackets and stainless‑steel hardware ensure long‑term stability.

Charge Controller

Manages charging/discharging to protect the battery from overcharge or deep discharge.

Ideal For

Rural Roads & Villages: Where grid power is unavailable or unreliable.

Urban Pathways & Parks: Enhances safety in pedestrian areas without trenching for cables.

Community Centers & Schools: Provides dependable lighting for evening activities.

Commercial Complexes: Reduces electricity bills and carbon footprint.

Emergency & Temporary Sites: Rapid deployment for construction zones or events.

Benefits

Energy Independence

Energy Independence: Runs completely off solar power—no grid connection needed.

Lower Operating Costs

Eliminates monthly electricity bills and reduces maintenance expenses.

Environmental Impact

Zero direct carbon emissions, supports clean‑energy goals.

Automatic Operation

Automatic Operation: Dusk‑to‑dawn sensors and controllers enable hands‑free functionality.

High Reliability

Battery backup and intelligent controls maintain illumination through power outages and low‑sunlight days.

Enhanced Safety & Security

Consistent, high‑quality lighting improves visibility, reducing accidents and deterring crime.

FAQs
How much sunlight is required for the streetlight to be charged?

The streetlight can run for 12 hours even with 2.5-3 hours of sunlight to charge the batteries.

Can these lights be dimmed or scheduled?

Yes—advanced controllers can implement dimming schedules or motion‑activated boosts for extra savings.

What lifespan can I expect?

High‑quality LEDs and lithium batteries typically last 5–7 years, with panels rated for 20+ years.

What are the warranty terms?

The Systems are warranted for 1 year. Solar Panels are warranted for 5 years. Charge Controllers, Electronics part of Luminaries are warranted for 3 years. LiFEPO4 battery is warranted for 3 years. Pole and LED is warranted for 1 year.

High Mast Lights

High Mast Lights

Solar high mast lights are tall‑pole lighting systems powered entirely by solar energy, designed to illuminate large outdoor areas such as city-centers, stadiums, highways, ports, and industrial yards without relying on the electrical grid. With automatic dusk‑to‑dawn sensors and smart controllers, they deliver hands‑free operation and resilience during outages or in remote locations

Solarising Water Purification Unit

Solarising Water Purification Unit

Solarising water purification units entails the use of photovoltaic power to drive water treatment processes, producing clean drinking water from sources like rivers, wells, or groundwater.

Major Components

Solar Panels

Provide electrical power for pumps and electronics.

Solar Pumps

For pumping water to the treatment processes and giving water through output pipes.

Battery

Stores generated energy for nighttime use.

Ideal For

Rural & Off‑Grid Communities lacking reliable electricity and safe water supplies.

Disaster Relief & Humanitarian Aid where rapid deployment of clean water solutions is critical.

Agricultural & Livestock Operations needing clean water for irrigation or animal use.

Coastal & Island Settings requiring desalination of seawater for drinking and irrigation.

Benefits

Zero Fuel & Low OpEx

Eliminates diesel generators and grid dependence, reducing operating costs.

High Water Quality

Multi‑barrier treatment ensures removal of harmful of pathogens, chemicals, and salts.

Sustainable & Green

Zero direct CO₂ emissions and minimal carbon footprint support climate goals.

FAQs
Will the existing treatment process or equipment need to be replaced?

No. The solar system is designed to complement the current setup. Only electrical components—like pumps or control panels—may be upgraded if required for energy efficiency or compatibility.

Can the plant operate during non-sunny hours?

Yes. The system includes battery backup or hybrid options to ensure uninterrupted operation during cloudy days or at night, depending on the design.

Is the plant completely independent of the grid after solarisation?

Not necessarily. It can be designed as Off-grid (fully independent), Hybrid, or Grid-tied.
