Increasing
human activity has a significant impact on energy. Most of the use
of energy by human
activities such as energy resources are non-renewable.
These problems can cause problems, especially electrical energy crisis. Electrical energy is the energy that
is necessary for humans. Can not imagine what would happen if electricity
production is not proportional to the demand. Power outages and all activity
came to a standstill, including economic activity. In order to meet increasing
electricity and fuel saving measures petroleum, efforts need to be done to look
for potential sources of renewable energy in all parts of Indonesia such as water
potential, wind, geothermal or sunlight.
The geographical condition of Indonesia, which consists of
small islands and remote causes many difficult to reach by the power grid are
centralized. To meet energy needs in these areas, one type of energy is
potential to develop solar energy. Due to the location of Indonesia located on
the equator, Indonesia has a solar radiation levels are extremely high.
According to the measurement from the center of Meteorology and Geophysics
Agency estimated the radiation falling on the surface of the Earth Indonesia (particularly
Eastern Indonesia) on average approximately 5.1 kWh / m2 day. Thus, solar
energy can be utilized for electricity providers in order to speed up rural
electrification ratio.
In
the utilization of solar energy that can be used
solar panels convert
solar energy directly
into electrical energy. The use of
solar panels as a
source of energy engineering
in electrical energy generation can be said to not produce
pollution, both air
pollution and pollution of the surrounding environment. The advantage of the
economic utilization of the solar cell is
1.
Save,
because it does not require fuel
2.
Can
be installed anywhere and can be moved as required
3.
Characteristically
modular. The capacity of the electricity produced can be adjusted by means of
assembling the modules in series and parallel
4.
Can
be operated automatically or using the operating
5.
Without
sound and do not cause pollution
Based on these considerations, photovoltaic conversion of
sunlight into electrical energy will be the main energy source of the future,
especially when conventional energy sources (coal, petroleum and natural gas)
is up. In addition, the price of conventional energy sources will continue to
be higher and supply is also very limited, while the photovoltaic prices will
gradually fall due to abundant raw material on earth.
Furthermore, the electrical energy generated from the solar
panels, can be used for a variety of uses, for example in the field of marine.
Utilization of solar cells as power supply lighting equipment to move the ship
or boat with the help of electric motors. With the requirement for electricity
to drive the growth of economic activity, improving intelligence where children
can learn and encourage the growth of settlements and welfare of the local
community, so as to support the creation of a prosperous society and in the
region to support regional development.
