PREFACE
The main non-renewable sources of energy in the
world are coal, oil, natural gas, and more recently
nuclear energy.
While the aforesaid power generators use coal, oil &
natural gas as their main fuel for energy production,
nuclear energy employs the technique of nuclear
fission of uranium for electricity generation.
The availability of these natural resources in future &
pollution are the main concerns.

PREFACE
The main renewable sources of energy in the world
are hydroelectricity, wind & solar energy.
Hydroelectric power plants cannot use water
continuously for electricity generation as they need to
maintain the level of water on both sides of the dam
for survival of aquatic life as well as prevention of
flooding in the area. This reduces its efficiency.
On the other hand, sunlight (in the desired angle)&
winds(in the desired direction) may not be available
throughout the day thereby reducing the efficiency of
the system

SOLAR POWER-AN INEXHAUSTIBLE
ENERGY SOURCE
Solar power, unlike other energy
sources, is now considered to be the
best alternative due to its versatility
in terms of renewability, cost-
effectiveness, improved operating
efficiency and last but not the least its
unlimited reserve, mainly being the
Sun.
The solar panels, being the modern
tech of alternative power source, aims
at absorbing maximum amount of
sunlight and converting into useable
electricity, and thus achieving
increasing popularity since the
realization of fossil fuel shortcomings.

DESIGN EVALUATION
 The main concern was whether the
materials used in the design would
be sufficient to hand the expected
loads and forces on the system
 The loads applied were gravity and a
65 mph wind normal to the solar
panel
 The system weight, size and
functionality was also evaluated

APPLICATION & SCOPE
The solar tracker system provides numerous applications in the field of
industrial, infrastructural as well as agricultural sectors, both private and public
purposes.
Its main application lies in the industrial processes like energy stations and
powerhouses for the production of electricity. Moreover, it also find its
applications in pool filtration systems, in agriculture for irrigation methods and
solar water heating systems.
