Solar Street Lights
.
Demand for electrical energy is increasing day by day and the
generation of the same is not increasing proportionately. The
gap between demand and generation is increasing as the sources
of fossil fuels are drying up fast. The atmospheric pollution is
getting worse due to the fumes produced by the use of
hydrocarbon-based fossil fuels.
We have taken the initiative to promote Solar Energy systems and
designed below mentioned Solar systems to meet the end user
requirements.
Solar Lanterns (3 models), Solar Home Systems (5 models), Solar
Street Lighting systems (2 models), Solar Water Heater Systems,
Solar Power Packs, Solar Refrigerators, Solar Air Dryers and
many more.
Scope of Supply:
Solar module 1 no. of 12V / 74W or 2 nos. of 37Wp.
Sealed Maintenance free or Low maintenance Lead Acid battery 12V
/ 75AH: 1 no.
Luminary with 11WCFL and automatic dusk to dawn operation: 1 no.
Interconnecting Cables: 1 set.
Pole, Battery box, Module mounting structure and accessories: 1
set.
Principle of Operation:
Solar modules consist of Solar cells connected in between for
the desired parameters. Solar cells generate electricity when
direct sunlight fall on it and is multiplied based on the number
of cells used. The generated electricity is used to charge the
Battery through a Charge Controller. Thus the generated energy
is stored in a Battery. The lighting load is connected to the
battery through CCU incorporated in the Luminary itself. The
lights will be switched ON automatically as soon as the Sun sets
and switches OFF when Sun rises in other words the Light will
operate from Dusk to Dawn automatically.
The Charge Controller (CCU) is the heart of the system, which
controls the charging, discharging of the battery, Solar module
and the light. CCU will increase the Battery life by not
allowing the battery to deep discharge and overcharge. During
deep discharge conditions the CCU will disconnect the light and
a red LED glows on the Luminary indicating that the Battery is
low and needs charging. The green LED on the Luminary indicates
that the Battery is resuming charge. During overcharge
conditions the CCU will disconnect the Solar module and prevents
overcharging of the Battery.
All the Solar Street Lighting systems are designed for three
days of autonomy i.e. if there is no Sun available or direct
Sunlight is not available, the light can still be used for a
maximum of three days without any interruption.
Location of Street Light System:
The Solar streetlight should be located in a shadow free area or
place where direct sunlight is available throughout the day.
DO's of Solar Street Light System:
1. Make sure that the Direct sunlight is falling on the Solar
module
2. Make sure that the Solar module surface is clean. Use water
for cleaning the surface.
3. Make sure that the fuse is replaced with correct rating.
DONT'S of Solar Street Light System:
1. Do not pour acid, detergent etc to clean the solar module
surface.
2. Do not cover the solar module with protective grills etc, as
this will reduce the light falling on the solar module.
3. Do not try to service / repair the Luminary. Call the service
personnel.
4. Never short the battery either directly or indirectly.
5. Direct sunlight on the battery should be avoided.
