ABSTRACT
INTRODUCTION
The spectrum of solar energy is
quite wide and its intensity varies
according to the timing of the day
and geographic location.
Solar energy is energy provided by the sun in
the form of solar radiation and it is the world’s
most abundant permanent source of energy.
The amount of solar energy intercepted by the
planet Earth is a tiny fraction of the solar
radiation emitted by the sun. However, even
that tiny amount is 5000 times greater than the
sum of all other inputs (nuclear, geothermal,
and gravitational energies and lunar
gravitational energy).
We review solar energy
conversion into electricity with
particular emphasis on
photovoltaic systems, solar cells
and how to store electricity.
And we will talk about what is the
solar panel (photovoltaic), what is
the composition of the PV, How
the solar panels (PV) work, The
world power generation,
Employment by technology,
Egypt production of solar energy
and the future of Egypt after
building Benban solar bark the
largest station in the world which
will provide more than 10,000 job
opportunities over four years and
the total production capacity of
the project might reach 2,000
megawatts.
Solar energy is a renewable resource and it is
becoming increasingly common that this
energy is converted and used as an alternative
to fossil fuels.
HOW DOES PV WORK
• The sun's light is absorbed by the solar panels.
• The silicon and conductors in the panel convert
the light into Direct Current (DC) electricity,
which then flows into the inverter.
Solar is represent a low percentage of the
production of Renewable energy in Egypt.
It is expected that by 2022 solar energy will
represent 2% of renewable energy in Egypt
• The inverter converts the DC into Alternate
Current (AC) electricity, which is used in your
home.
• Any additional electricity that's not used by your
home goes via your home's meter into the mains
power grid for others to use.
• Electricity is drawn from the grid when you need
more power than your solar energy system
produces. As in figure 3.
Solar panel electricity systems, known as
photovoltaics (PV), capture the sun's energy
using photovoltaic cells.
These cells don't need direct sunlight to work
they can still generate some electricity on a
cloudy day.
The cells convert the sunlight into electricity,
which can be used to run household
appliances and lighting.

Egypt's production
in solar energy

WORLED POWER GENERATION
Egypt building a solar power station in
Aswan (Benban solar park), which is the
largest station in the world, where will
generate the equivalent of 90% of the
energy produced from the dam. And the
total production capacity of the project
might reach 2,000 M/watts. And the project
would provide more than 10,000 job
opportunities over four years, with priority
to city’s inhabitants.

The top layer is usually glass with improved
characteristics.
POE - Poly Olefine Elastomer is used to hold
the cells and in fact the entire framework
together.
Solar cells are sandwiched between two POE
layers.
The bottom most part of the module can be
backsheet or glass depending on the kind of
module. As in figure 2.
