CHAPTER III

METHODOLOGY

This chapter covers the methods and procedure undertaken by the researchers.

It is composed of four parts namely Site and Load Assessment, Data Gathering, System

Design, and conomic Analysis.

3.1 Project Design

This diagram helps readers for an easier understanding of the methods

undertaken by the researchers. This pro!ect design indicates the order of the tasks

underdone by the researchers to complete the pro!ect.

3.2 Project Locale

This section indicated the location &here the study &as conducted.

3.3 Project Instr !ents

This section of the method undertaken by the researchers indicates the

instruments used to ac'uire a specific data.

3.". Project Proce# re

"ollo&ing the pro!ect design, under this section &ill be the data ac'uired,discussions on a specific section of the pro!ect design

3.".1 Data gat$ering

To design a %( system, Site and load assessment is necessary.

Availability of sunlight on the site and the solar panel)s energy output needs to be

assessed.

3.".1.1 %olar Insolation

To determine the solar insolation for the location selected for the

solar po&er system to be designed.

3.".1.2 Location o& Panels

To determine the location of solar panels, certain factors must be

considered* it must receive a great amount of sunlight +considering solar



insolation , there should be no or at least a little obstacles for the sunlight

to reach the panels- and the location of the panels should be near to the

load to be supplied to minimi e losses.

3.".1.3 Loa# Esti!ation

It is necessary to determine the load to be supplied by the proposed

system. The monthly electric consumption of /S01GS2 &ill be collected

and &ill be used for computations of the estimated economic advantages

of the system.

3.".2 Cost an# %'eci&ications

0nder this section &ill be the data especially the cost and specifications of

the components used in the estimation of the system designed.

3.".2.1 %election o& %(ste! Co!'onents

In designing of %hotovoltaic System, it is desirable to select high

'uality and efficient components. Also, availability &ithin the region and

price of the materials is to be considered.

3.".3 %(ste! Design

0nder this section &ill be the product of the pro!ect &hich is the design of

the solar po&er system along &ith discussions and remarks made by the

researchers based on observed and researched data.



3.".3.1 Design %'eci&ication

It is important to properly utili e the components from reno&ned

manufactures &ith good reputation in designing the system. This section

&ill tell &hat kind of solar po&er system &ill be used for the design.

3.".3.2 Tilt an# Orientation

To get the ma3imum energy from the sun, the best possible tilt and

orientation must be determined.

3."." Econo!ic Anal(sis

0nder this section &ill be the computation of different common economic

interest of a pro!ect.

3.".".1 Cost Esti!ation o& %(ste! Co!'onents

stimation of the system components are obtained from different

suppliers around the %hilippines. 2omparison among these prices and

specifications &ill determine &hich components &ill be used.

3.".".2 %(ste! Co!'onents Li&e %'an

Life Span of the components of the system is significant for the



economic analysis for it determines the amount of time the system &ill be

useful.

3.".".3 E)'ecte# Pa(*ac+ Perio#

This chapter covers the data gathered by the researchers for the study follo&ing

the methods set.

".1 Project Locale

The researchers are currently 4 th year lectrical ngineering Students of

/indanao State 0niversity General 2ity 2ampus. The pro!ect is conducted at the

ngineering Laboratory of /indanao State 0niversity General Santos 2ity.

".2 Project Instr !ents

In ac'uiring re'uired data, the researchers used the follo&ing instruments*

Ladder and surveying tape 5 for manual measurement of the roof)s

dimensions.

components considered in designing the system.

%election o& %(ste! Co!'onents

"or the components used in this study, the researchers used the

products of the local companies such as FSolar System %hilippines . The

reason of the researchers for this is that these suppliers are local, and

prices obtained from these suppliers if not e3act, are nearly the range of

products locally available.

"or components not included in the 'uotation and prices taken fromlocal suppliers, the researchers used products from other international

suppliers to have an estimate of the cost.

The components used in this study may or may not be the

components to be used in the actual implementation, thus prices may still

go do&n and overall cost may be lo&er of this pro!ect)s design.
