Sahaj Solar Pvt Ltd

Solar Streets

Sahaj Solar street lights are well-designed to illuminate large areas with the highest intensity of light. Sahaj Solar offers a wide variety of configurations and styles to meet your specific needs. The fully integrated system combines the latest and most innovative technologies available.

Solar Street Light System

Solar Street Light System is designed for outdoor application. Which is ideal lighting system for the illumination of streets, squares and cross roads located in areas that are not connected to the power grid, the system is provided with battery storage backup sufficient to operate the light for 10-11 hours daily. The system is controlled by a controller with automatic ON/OFF time switch, which control the light from dusk till morning or other setting time. An overcharge / deep discharge function can keep the battery on working a long time. Our solar street lighting system is a live paradigm of quality and innovative technology, available on very affordable rates.

LED Based Solar Street Light

LED Based - An LED Light which has LED light bulb is a solid-state lamp that uses light-emitting diodes (LEDs) as the source of light. LED lamps offer long service life and high energy efficiency. Chemical decomposition of LED chips reduces luminous flux over life cycle as with conventional lamps.

Features of LED LIGHT

Maintenance-Free
Dusk to Dawn, Automatic ON/OFF.
A complete shock proof system.
Low Battery & Battery Charging Indication.
Low Battery, Over Charging.
Reverse / Short / Open Circuit & No Load Protections.
Fast and simple installation.
Location flexible.
Maintenance-free & Automatic operation.
High reliability & Long lifetime.

Benefits of an LED street Light

Long life; an estimated 50,000+ hour's operation.
Reduced maintenance cost due to long life.
Good efficiency; comparable with a fluorescent lamp.
Small compared with other lamps of same output.
Instant start (no warming up period), Immune to power outages.

LED street Light Most Beneficial for:

Outdoor Area lighting
Campus Lighting
Garden Lighting
Parking lot lighting
Parkway lighting
Walkway lighting
Security Lighting

CFL Based Solar Street Light

It compromises of one Solar Streetlight Luminary (SSL) using Compact Fluorescent Lamp (CFL) Rechargeable Lead Acid battery for storage, PV modules for charging the battery, suitable electronics for the operation of the lamp and safe charging and discharging of the battery and mechanical hardware for fixing these sub systems.

Features of CFL Light

Stand alone system
Dusk to Dawn, Automatic ON/OFF.
2 to 3 day's autonomy
Indications: Low Battery & Battery Charging
Two step charging algorithm.
Temperature compensated battery set points.
Weather proof luminaries

Benefits of Solar CFL

No Strains & Pains of Manual Operation
Very little maintenance is required
Up to four times more efficient
Highly efficient charge controller and Invert.
Required area(small)

Solar CFL Most Beneficial for:

All type of Institution
Hotel
Hospital
Industry
Interior area
Hills area
Home street
