Abstract

As
we know that today every country shown great attention toward solar energy
because it is a great source of renewable energy. They make such devices or
system that convert this solar energy into electrical energy. This conversion
can be done by two different method one is direct method while the other is
indirect method.

In
direct method solar energy is directly converted into electrical energy through
photovoltaic (PV) while in indirect method solar energy first convert into heat
energy and then this heat energy or steam can be converted into electricity
through concentrated solar power (CSP) system.

In
our project we will present the comparative study between these two types of
solar power panel (PV & CPV). Our study includes different quality
standards that improve the quality of these two types of solar panel and it’s
include their components, types, cost, efficiency, advantages and
disadvantages.

1 Introduction

Today
the most power full source of energy on the earth is Sun. Every type of energy
such as wind energy, biomass, hydro, fossil fuel etc. having their origins is
sunlight that can be produce by sun. According to research sun can fall solar
energy at the rate of 120 petawatts on the surface of the earth as shown in fig.1.
Its mean the total energy that sun can fall on the surface of the earth in one
day would full fill to satisfied the requirement of whole world for more than
20 years.1

Renewable
energy is such type of energy that is comes from some natural resources such as
sunlight, wind, rain, geothermal heat etc. All these resources are renewable
and that can be produced though natural phenomena. Therefore we will be able to
consider these resources to be inexhaustible in all practical purpose.2(3)

These
all Renewable energy sources only solar technologies will capture the interest
of all the researcher or people who are working on Renewable energy sources. In
the whole market of the world these solar power system can be divided into two
classes the first one is direct while the other one is indirect solar power. In
direct method solar energy is directly converted into electrical energy through
photovoltaic (PV) while in indirect method solar energy first convert into heat
energy and after that this heat energy or steam can be converted into
electricity through concentrated solar power (CSP) system. In CSP the main
problem in these technology is their inefficiency and their high capital cost

As shown in figure 1.1, 1.2 we can see how the conversion can take place in PV
System and CSP System.
