SOLAR ENERGY

Solar energy is the ultimate source of energy from millions of
years and it is a renewable energy.
This energy consists of radiant light and heat energy from the sun.
Out of all energy emitted by sun only a small fraction of energy is
absorbed by the earth.
Just this tiny fraction of the sun’s energy that hits the earth is
enough to meet all our power needs.
Using present solar techniques some of the solar energy reaching
the earth is utilized for generating electricity etc….
Even then the energy demand met by using solar energy is very
less.
How solar energy is used
•
We can use solar energy by converting it to electrical energy . So we must use a
device called solar panels which can convert the light energy into electrical energy.
Solar panel is a group of solar cells.
Solar cells works on the principle of photoelectric effect.

PHOTOELECTRIC EFFECT
•
•
•
When a light of certain frequency falls on the surface of a metal , electrons will
absorb the energy . If incident light energy is
greater than the work
function(minimum energy required to remove the loosely bound valence
electrons)of the metal ,then the photo electrons will be emitted and the excess
energy is converted to the kinetic energy of electron.

SOLAR HOME LIGHT SYSTEM
Home lighting solar system are the
fixed installation design for domestic
application. The components of solar
lighting system include solar pv
module, charge controller, solar
battery and lighting system.
ERA Renewable Energy
SOLAR STREET LIGHT
Solar street light is an 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 provided with battery storage
backup sufficient to operate the light
for 9-10 hours. The system is
provided with automatic on/off time
switch for dusk to dawn operation.

SOLAR WATER PUMP
A solar water pump system is
essentially an electrical pump system
in which the electricity is provided by
one or several Photo-Voltaic (PV)
panels. A typical solar powered
pumping system consists of a solar
panel array that powers an electric
motor, which in turn powers a bore or
surface pump. The water is often
pumped from the ground or stream
into a storage tank that provides a
gravity feed, so energy storage is not
needed for these systems.

SOLAR WATER HEATER
Solar Water Heater is a device that
helps in heating water by using the
energy from the SUN. Solar energy (sun
rays) is used for heating water. Water is
easily heated to a temperature of 6080o C. It consist of Solar Collector( to
collect solar energy), Insulated Tank (to
store hot water), Supporting Stand,
Connecting Pipes and Instrumentation
etc.

SOLAR LANTERN
A LANTERN is a lighting system
consisting of lamp, battery and
electronics all placed in a suitable
housing. The battery is charged by
solar photovoltaic modules, which in
turn can be used for lighting at night. It
has also mobile charging facility & AC
Facility.

SOLAR BATTERY
our batteries are approved by MNRE.
Our batteries are designed to give long
life in cyclic operations and extremely
long intervals in topping up and even
total freedom from maintenance.
Similar to the tubular battery offerings,
only difference being their capacity to
withstand partial state of discharge
(PSOC) operation
ERA Renewable Energy
CHARGE CONTROLLER
The charge controller is used to
regulate the current flowing from the
solar panels to the batteries. These
solar controllers prevent the battery
from the damages caused by
overcharged and disconnect the
battery in case of severe discharge by
shutting of loads.
ERA Renewable Energy
SOLAR PANELS
A solar panel is a set of solar photovoltaic
modules electrically connected and
mounted on a supporting structure. A
photovoltaic module is a packaged,
connected assembly of solar cells. The solar
module can be used as a component of a
larger photovoltaic system to generate and
supply electricity in commercial and
residential applications. Each module is
rated by its DC output power under
standard test conditions (STC), and typically
ranges from 100 to 320 watts.

LED BULB & DOWN LIGHT
A light-emitting diode (LED) is a semiconductor light source. LEDs are used
as indicator lamps in many devices and are increasingly used for general
lighting.
