Friends, all of us now that we
can generate electricity from the solar energy by two means, the first one is by
photovoltaic systems (PV) which convert the sun radiation directly to
electricity and the second
one is by solar thermal
energy systems (CSP) which convert the solar radiation to a thermal energy then
to electricity . In the year 2020 the installed power of solar
energy systems used to generate electricity will exceed the installed power of hydropower,
wind and nuclear systems which used also to generate electricity.
Of course it is a matter of
time until solar electricity will be the number one of electricity generation technology,
let us see why ??:
First:
Solar radiation is available at
all places on the earth and in a high abundance as the amount of energy that arrives
to the earth is about larger than ten thousands times the total energy required
for all the humans .In the same time solar energy is the largest energy source available
of renewable energy sources.
Second:
Solar electricity is a clean electricity
generation source, so no environmental side effects which lead to dangerous
earth warm due to green house gases.
Third:
For solar photovoltaic electricity
systems there will not be a high cost of maintenance and operation. They
represent a fraction comparing to other fossil fuels electricity generation
systems cost.
Fourth:
Building anew renewable energy
plants like hydro or nuclear and even fossil fuel plants require large investment.
In the same time using photovoltaic system can be installed decentralized i.e.,
every one can use its building roof to install PV system and generate electricity
for its home need and when he needn’t this electricity , he can buy it to the
electricity utility . By this mean, we can face our increased requirements of
electricity without the need to such high capital cost required to establish
anew electricity power plant.
We believe that solar
electricity is the coming revolution that will change our electricity
generation landscape especially photovoltaic solar electricity systems that
will be the force behind this revolution due to its high growth rate in most of
world countries.
