SOLAR PRESENTATION - BASICS

SOLAR ENERGY

RENEWABLE

SOLAR ENERGY

ENERGY FROM THE SUN
❑THERMAL/HEAT ENERGY
❑ELECTRICAL ENERGY

WHY SOLAR ENERGY ?

▪ World Energy Conservation predicted :
Coal deposits will deplete within the next 200 to 300 years
Petroleum deposits will deplete in next few decades

▪ The most advantage using Solar Energy is that this is
distributed over a wide geographical area.

POLLUTION EFFECT..

The huge consumption of fossil fuels has caused visible
damage to the environment in various forms

The amount of
Carbon & Sulphur
deposited in the atmosphere

Transportation 8 billion tons
Fossil Fuel 6.5 million tons

Deforestation and forest firing 1.5 million tons

SAVING OF WATER

.

RENEWABLE ENERGY
CONSUMPTION

SOLAR PANEL
WORKING

❑ Sunlight hit the solar panel
(photovoltaic/ PV) and absorbed by
semi-conducting materials silicone (Si).

❑ Electrons are knocked loose from their
atoms, which allow them to flow
through the material to produce
electricity. This process is called the
photovoltaic (PV) effect.

❑ An array of solar panels converts solar
energy into DC (direct current)
electricity.

❑ The DC electricity enters an inverter.
❑ The inverter turns DC electricity into

220-volt AC (alternating current)

SOLAR PLANT WORKING-
NET METERING

❑ When solar energy is generated it is supplied to
the utility grid .

❑ The flow of electricity in and out of the utility grid
is measured by a UTILITY METER [TWO WAY
METER]

❑ The two are offset ensuring that you only pay for
the additional energy you use from the Electricity
Dept./Power Supply Company.

SOLAR PLANT WORKING

FINANCIAL ADVANTAGES...

Saves your money

❑ After the initial investment has been recovered, the energy from the
Sun is practically FREE.

❑ Solar Energy does not contribute to the cost and problems of the
recovery and transportation of fuel or the storage of radioactive waste.

❑ Subsidies are available form the government that reduces cost.

ENVIRONMENTAL ADVANTAGES…

Environment friendly

❑ Solar Energy is clean, renewable (unlike gas, oil and coal),
Sustainable and helping to protect our environment.

❑ Solar Energy does no pollute air.
❑ Solar Energy does not contribute to Global warming, Acid rain

or Smog.
❑ Solar Energy actively contributes to the decrease of harmful

Green House Gas Emissions.

OPERATIONAL ADVANTAGES …

Low/ No maintenance

❑ Solar Energy systems are virtually maintenance free and will last
for decades.

❑ Solar Energy plant once installed, there are no recurring costs.
They operate silently, have no moving parts, do not release
offensive smells and do not require you to add any fuel.

❑ More solar panels can easily be added in the future when your
family's needs grow subject to space and load sanctioned

DRAWBACKS

❑ The initial cost because of the high cost of the semi-conducting
materials used in building one.
[ LOAN POSSIBLE ]

❑ Solar panels require quite a large area for installation
[ FOR GOOD LEVEL OF EFFICIENCY]

❑ The production of solar energy is influenced by the presence of
Clouds or Pollution in the air.

CONCLUSION !

A 1-kilowatt home solar system will prevent :
❑ Approx. 76 kg of coal from being burned
❑ 135 kg of CO2 from being released into the atmosphere
❑ 398 liters of water from being consumed each month

ALL THE BEST !
