Abstract
PV production, explaining the advantages and disadvantages of each of these
programs and analyzing the study area in terms of the rate of production of
electric power per square meter m flat cells on the university surfaces and the
appropriate places for the installation of PV panels and the amounts of electric
power produced at Pharos University and their economic and environmental
returns as well as calculating electricity consumption bills for a period from
2015 to 2019 and assessing the extent of savings by using PV cells.This chapter
includes all data as electric bills, rooftop area, geographical data, solar density, and
PV sizing software with input and output data.
3.2. Research work procedure
1- Knowing the electric power consumption and its cost through previous bills.
2- Study the available alternative energy methods in the region and their economic and
environmental impact and compare them.
3- Conducting studies for the university buildings and determining the areas that can be
used to install the PV modules.
4- An economic feasibility study is carried out to measure the financial return of the
university from the use of PV technology using programs Microsoft office.
5- Using specialized programs in PV calculations to determine the size and capacity of
the units to be installed and to compare between the various programs and determine
the most appropriate ones for application in the case of the study It is one of the most
accurate and widely used programs worldwide
