Earth receives 174 petawatts (PW 1015 W) of
incoming solar radiation at the upper atmosphere
at any given time

SOLAR AVAILABILITY
In Nigeria, solar radiation intensities range
between 3.5 to 70kWhm2/day, with an average
solar radiation intensity of 5.535kWh/ m2/day.
The average sunlight duration is about 6 -
6.5hours daily. The average annual solar energy
incident in Nigeria is approx. 1.8041015kWh and
this value is about 27 times the country's total
fossil energy resources in energy units and over
115,000 times the electrical power produced.

SOLAR PHOTOVOLTAIC APPLICATION
Photovoltaics (or PV) is the field of technology
related to the application of solar cells for
energy by converting solar energy directly into
electricity A solar cell, or photovoltaic cell,
is a semiconductor device consisting of a
large-area p-n junction diode, which in the
presence of sunlight is capable of generating
usable electrical energy. Materials that absorb
the visible light are known as semiconductor
materials. Semiconductor is a poor electrical
conductor
6
If a piece of p-type silicon is placed in
intimate contact with a piece of n-type silicon,
then a diffusion of electrons occurs and current
will flow
Examples of semiconductor materials employed in
solar cells include silicon, gallium arsenide,
indium phosphide, and copper indium selenide.

SOLAR ENERGY THERMAL APPLICATION
A solar thermal plant is composed of two quite
distinct fields. First is the power block which
is quite similar to the power blocks installed in
any electrical power plant. This power block is
comprised of a series of units such as the
turbine, alternator, condenser, exchangers, pumps
etc., which are units that have been extensively
tested in the industrial market and are produced
by a large number of manufacturers.

TECHNOLOGIES
Concentrated Solar Power (CSP) Technology systems
use mirrors or lenses with tracking systems to
focus a large area of sunlight onto a small area.
The concentrated light is then used as heat or as
a heat source for a conventional power plant
(solar thermoelectricity). The solar
concentrators used in CSP systems can often also
be used to provide industrial process heating or
cooling, such as in solar air-conditioning.
10
CSP TECHNOLOGIES

• Concentrating technologies exist in five common
  forms, namely
• Parabolic Trough Solar Electric Generating
  System
• Enclosed Trough
• Dish Stirlings System
• Concentrating Linear Fresnel Reflector and
• Solar Power Tower
• The different components of a solar power plant
  can be manufactured in Nigeria and professionals
  can also find space in that segment of solar
  power value chain
