What Is a Solar Street Light?
Roads Are Illuminated by the Sun - Not the State Grid
A solar street light is a self-contained outdoor lighting system in which a solar panel, LED luminaire, charge controller, and rechargeable battery are combined into one unit - or distributed across a split-design pole. The system is charged during the day and is operated throughout the night using stored solar energy, with no connection to the electricity grid required at any stage.
At PSD Energy & Water Pure System, solar street lights have been supplied and installed for residential colonies, industrial campuses, rural roads, government projects, and institutional premises across Karur and Tamil Nadu - with capacities ranging from 12W domestic pathway lights to 200W high-mast highway luminaires.
"A single 40W solar street light that replaces a conventional 40W sodium vapour fitting can eliminate an electricity cost of ₹180–₹220 per month per pole - across a 25-year service life."
Automatic Dusk-to-Dawn Function
An in-built light sensor has been incorporated so that every solar street light is switched on automatically at dusk and switched off at dawn - requiring no manual operation at any point.
PIR Motion Sensor Option
Passive infrared motion sensors are optionally integrated so that lights are operated at 30% brightness during low-traffic periods and brightened to 100% automatically when movement is detected.
Designed for Tamil Nadu Climate
Every system is rated IP65 or above and is engineered to withstand the heat, humidity, rain, and dust conditions specific to Tamil Nadu - with no compromise to performance or lifespan.
System Types
All-in-One or Split Design? The Right Fit for Every Road
Two solar street light configurations are available - selected based on road type, required lighting level, pole height, and budget. A free site assessment is conducted before any system is recommended.

High CapacityHighways & Industrial Campuses
Split Solar Street Light
High Power · Industrial Grade · Flexible
In split-design solar street lights, the solar panel is mounted separately at the top of the pole while the battery box is installed at mid-pole - allowing larger panel and battery capacities to be accommodated for high-wattage applications.
- Higher wattage range - 60W to 200W LED
- Larger battery for extended backup nights
- Suitable for highways and industrial roads
- Panel angle is independently adjustable
- Replaceable battery without pole work

What's Inside Every System
Only Premium-Grade Components Are Used
Every component is selected for performance reliability in Tamil Nadu's climate - where ambient temperatures, monsoon rains, and dust exposure place real demands on outdoor electrical systems throughout their working life.
Monocrystalline Solar Panel
High-efficiency monocrystalline PV panels rated at 17–22% efficiency are used - providing reliable daily charging even during partial shade or slightly overcast mornings in Tamil Nadu.
LED Luminaire (12W–200W)
Branded LED luminaires with luminous efficacy of 130–160 lm/W are specified - delivering maximum brightness at minimal battery draw, with a rated operational life of 50,000 hours.
Lithium Iron Phosphate Battery
LiFePO4 batteries are preferred for their 2000+ cycle life, superior thermal safety, consistent capacity in high-temperature environments, and a service life of 5–7 years.
MPPT Charge Controller
Maximum Power Point Tracking (MPPT) controllers are integrated to extract up to 30% more energy from the solar panel compared to conventional PWM controllers - maximising night hours.
PIR Motion Sensor
Passive infrared sensors are optionally installed so that luminaires are dimmed to 30% brightness during periods of inactivity and brightened automatically when movement is detected.
IP65-Rated Enclosure & Pole
All systems are housed in IP65-certified enclosures and are mounted on hot-dip galvanised steel poles - ensuring corrosion resistance and structural integrity for 20+ years.
