SOLAR STREET LIGHT TECHNICAL SPECIFICATION
1. GENERAL SOLAR STREET LIGHT DESIGN REQUIREMENT
GENERAL
The solar street light scope of supply shall consist of the design, production of
materials, manufacturing, drawings and data, assembly, painting, testing, inspection and all
all in accordance with applicable codes and standards and any additional requirements of this
specification,the Solar street light operates from Dusk to Dawn i.e., the lamp automatically
switches ON after the sunset and switches OFF after sunrise.
The solar street lighting systembasically
consists of:
a) Solar photovoltaic Module
b) Luminaire/LED sreet light
c) Low maintenance battery
d) Pole and solar panel bracket
e) Battery box
f) Interconnecting cables
The solar photovoltaic module is fixed firmly
on top of the pole with suitable tilt and
inclination so as to receive maximum sunlight
throughout the day. The solar photovoltaic module thus produces suitable voltage and current,
which is used to charge the battery inside the battery box. This energy stored in the battery
is used to light up the LED which is housed inside the luminaire during night time.
Energy efficient LED street lamps of at suitable watts with 25 Lux requirements, an inverter
and charge controller card, which is used to convert the stored DC energy in the battery to
suitable AC voltage to ignite the LED. A reflector is provided in the LED street light to
increase and spread the light uniformly.
The charge controller protects the battery from over charge and deep discharge.
The Solar photovoltaic module, led street lamp and the battery box are fixed on to the Pole
and are interconnected through the cables. The solar street light operates in the stand alone
mode.
The solar battery is housed inside a battery box, which is underground or fixed on to the
pole at a suitable height from the ground for easy maintenance and replacement. The battery
provided shall be low maintenance tubular lead acid type. This requires minimal maintenance
and has a long life with regular use. Periodical maintenance of the battery includes topping
up distilled water once in 2-3 months and applying petroleum jelly to the terminals to
prevent corrosion.
